To see how the weather is shaping up for the remainder of the country, click here. Figure 2 shows the departure from average temperature and percent of normal precipitation across the state from October 2020 through March 2021. And the next few weeks look like some hot and dry weather for the Pacific Northwest. Climate Dyn., 38, 1459-1471. This article was published more than1 year ago. Parts of the Northeast, Ohio Valley and far western United States could see heavy rains and snow toward the end of February. Thus, in general, the expected prediction skill is likely to be lower than for temperature. Here at Patch, some of us were on the hype train by early July. After our second-warmest October on record, the first week of November delivered a chill, offering a taste of the inevitable. Finally, precipitation will be near normal nationwide in March, the Farmers Almanac offered in a qualifier, noting that in a sense, March will be a microcosm of the entire winter., From start to finish, the month will be full of stretches of uneventful weather, but when it turns stormy, the precipitation will come in big doses, the publication said. The more vigorous storm track and slight tilt toward colder temperatures over the northern tier of the U.S. during La Nia modestly increase the chance of a relatively snowy winter. River Stages Meeting Agenda - May 16-17, 2023 - Washington State Transportation Winter 2022-2023 should be dominated by an active storm track in the eastern half of the country, running from the western Gulf of Mexico to the northeast, across the Virginias, and across interior New York State and New England. The Old Farmer's Almanac has released its winter forecasts, saying Western Washington can expect more rain than normal, with warmer temperatures and less snow. Higgins, W., J. Schemm, W. Shi, and A. Leetmaa, 2000: Extreme precipitation events in the western United States related to tropical forcing. Below are some, though not all, of the factors that we considered in determining conditions for this upcoming winter. Overall, we expect temperatures for December through February to be close to average. His unchanging location is associated with the persistent changes intropical rainfalland winds that we havepreviously describedas being linked to ENSO.

Climate Variability: North AtlanticOscillation (NAO). February should offer some reprieve from storms. By contrast, the latest seasonal outlooks from the National Oceanic and Atmospheric Administration place very good odds on Washington seeing a wetter fall and winter. Here's every snow forecast made for D.C. for the upcoming winter By Jason Samenow Updated December 3, 2021 at 4:24 p.m. EST | Published December 3, 2021 at 3:37 p.m. EST Long-Range Weather Forecast for 2022 | The Old Farmer's Almanac Winter temperatures will be milder than normal, with slightly below-normal precipitation and snowfall. Warmer and drier winters are more likely during La Nia over more southern states, and this is exactly where seasonal snowfall tends to be reduced (4). The MJO can modulate the timing and strength of monsoons (e.g., Jones and Carvalho, 2002; Lavender and Matthews, 2009), influence tropical cyclone numbers and strength in nearly all ocean basins (e.g., Maloney and Hartmann, 2000), and result in jet stream changes that can lead to cold air outbreaks, extreme heat events, and flooding rains over the United States and North America (Higgins et al. The green shading denotes above-average rainfall, and the brown shading shows below-average rainfall. Experts from the National Weather Service (NWS) in Seattle detailed an outlook for the upcoming winter season during the annual stakeholders meeting on Tuesday, forecasting above-average rainfall. While it's not a perfect correlation, about six or seven out of every 10 La Nina winters do end up colder than snowier than average in Spokane. Precipitation will be above normal, with above-average snowfall in the far north and far south. When the probability of the favored category becomes very large, such as 70% (which is very rare), the above rule for assigning the probabilities for the two non-favored categories becomes different. TEI and HEI are calibrated to match the recent climatology of tornado numbers and hail events. After we developed our own numbers for this winter outlook, we polled several forecasters who produce their own outlooks to compare. Maloney E. and D. Hartmann, 2000: Modulation of hurricane activity in the Gulf of Mexico by the Madden-Julian Oscillation. The storm track is, in turn, shifted northward across parts of the Ohio Valley and Great Lakes (2). Forecasts and model runs | Washington Department of Fish & Wildlife However, as is evident in these maps, there is a great deal of variability even among strong La Nia events. These model forecasts provide us with a signal for a La Nia event during the 2021-2022 winter season. NOAA typically releases its official winter predictions in October. Conversely, AO's negative phase has higher-than-average air pressure over the Arctic region and lower-than-average pressure over the northern Pacific and Atlantic Oceans. Forecast systems . Nisqually Boardroom 1D2. These analogues helped to loosely form the basis of our temperature and snow predictions because the weather in those years had some similarities to the factors below. The Northern Plains and Rockies may see a blizzard the third week of January. Meanwhile, the 30-year average snowfall has declined from over 20 inches in the late 1800s to just 13.7 inches today. Winter temperature differences from average (degrees F) during La Nia winters dating back to 1950. No single factor tells the whole story, nor are the correlations between past conditions and future conditions which we used to inform the outlook always strong. As air sinks from high altitudes, it warms and dries, which suppresses rainfall. NOAA Climate.gov drawing by Fiona Martin. NOAA's CPC Winter 2021-22 Outlook for the Upper Mississippi River Valley Released: November 18, . 2022 Forecasts. Release Date: Apr. 2023 Columbia River fall Chinook forecast (updated March 2, 2023) 2023 Columbia River spring/summer forecasts; Model Runs . We do take these long-term trends into account in our winter outlooks. Also, there is a tendency toward below-average snowfall over the mid-Atlantic, New England, and northern and central Plains, which is not seen during weak La Nia. These historical relationships along with guidance provided by a suite of computer models play a strong role in the final outlooks. Hospitals / Nursing Homes We can see this by comparing the right image below (more recent events) with the one to the left of it (older events). For Washington, Oregon and Idaho, the Farmers Almanac winter forecast calls for "typical winter temperatures and precipitation.". April 2023 . The typical U.S. impacts are warmer- and drier-than-average conditions across the southern tier of the United States, colder-than-average conditions across the north-central Plains, and wetter-than-average conditions in the Ohio Valley and Pacific Northwest/Northern California. But State Climatologist Nick Bond told KUOW's Angela King the almanacs forecasts for our region are about as good as flipping a coin. Experimental Graphical Hazardous Weather Outlook, retracted jet stream over the North Pacific. J. The mercury will be prone to both springlike spikes and bone-chilling plunges. Lavender, S. and A. Matthews, 2009: Response of the West African monsoon to the Madden-Julian Oscillation,J. Local Storm Report, Decision Support Image Credit: Climate Impacts Group, University of Washington. Northwest U.S. Archives - Farmers' Almanac AccuWeather's 2021-2022 US winter forecast Nationally, AccuWeather predicts an eventful winter similar to the 2020-21 season, which brought record-breaking snowfall and blackouts to some parts of the country. This was based upon recent trends over the past decade. For example, 8 of the 11 strong and moderate events show the cool conditions in the Northern Great Plains, which is most winters, but not all. Differences between the two periods for the precipitation composites are much smaller and therefore are not shown here. Sven R. Larson. The AO's positive phase is characterized by lower-than-average air pressure over the Arctic paired with higher-than-average pressure over the northern Pacific and Atlantic Oceans. The winter central Arctic surface energy budget: A model evaluation Review of Winter 2020-21 | Office of the Washington State Climatologist Western Washington forecast. The highest shift in the probabilities is from southern California into southwest Texas, much of Florida, southeast Georgia, and southeast Alaska. Thompson, D.W.J., and J.M. Wallace, 2001: Regional Climate Impacts of the Northern Hemisphere Annular Mode. I am also looking at the north Pacific, just south of Alaska. Tell us your plans in the comments section below. High pressure over Greenland or high-latitude blocking helps push the storm track farther south and east, often creating storm tracks that are cold and snowy for our region. There can be multiple MJO events within a season, and so the MJO is best described asintraseasonaltropical climate variability (i.e. It is true that there is no skill in predicting specific conditions, such as the exact temperature and amount of rain or snow for a given day, more than eight to 10 days into the future. Horizontal arrows pointing left represent wind departures from average that are easterly, and arrows pointing right represent wind departures from average that are westerly. Instead of only looking at individual weather events, its important to consider the environmental cues for the outbreak of severe weather. Last year was a La Nia year and we are looking at something similar this year as cooler water once again builds in the central Pacific Ocean. Zhang, C., 2005: Madden-Julian Oscillation. This failure of the typical pattern occurs because La Nia is never the only thing that influences the climate over the United States during the winter. Cooler ocean waters mean that winds over the Pacific are stronger than normal with means rainfall decreases over the northern-tropical Pacific Ocean and so on. 1: The tornado environment index (TEI) and hail environment index (HEI) are functions of monthly averages of convective precipitation, convective available potential energy, and storm-relative helicity. About WDFW . Sign up for free Patch newsletters and alerts. The Nio-3.4 index has a 66% chance of reaching a value less than -1.0C duringNovember 2021 - January 2022, but only a 14% chance of being below -1.5C. of Transportation: Information on travel alerts, road conditions, ferry schedules, construction areas, etc. The strength and placement of the jet streams, columns of fast-moving air that circle both the northern and southern hemispheres, is a noticeable effect of La Nia. However, these figures are based on about 20 different La Nia episodes, many of them from the 1950s, 1960s, and 1970s, and we have not removed the longer-term trends from the temperature and precipitation data used here. We graded our outlook a C+. Sometimes we're a little wet in kind of November and December in La Nina conditions, but not always. 2022 Columbia River spring-summer-fall forecasts; 2022 Chinook (statewide) 2022 Coho . Climate,15, 905-914. Cassou, C., 2008: Intraseasonal interaction between the Madden Julian Oscillation and the North Atlantic Oscillation. temperature and precipitation over the U.S. National Oceanic and Atmospheric Administration. In the maps, the CPC forecasts show the probability of the favored categoryonly when there is a favored category;otherwise, they show EC (equal chances). The federal budget deficit in 2022 exceeded $1 trillion and is widely expected to remain at that level for the foreseeable future. These are tricky forecasts, and we think well have our share of them this winter. Meanwhile, the winter weather will take its time arriving in the Southeast, with only mild temps in some place throughout December. The official Climate Prediction Center outlook is similar to these model forecasts, calling for a 70% chance for La Nia to continue through the 2021-2022 winter season. However, as is evident in these maps, there is a great deal of variability even among strong La Nia events. The snowiest periods will be in mid-November, late December, early to mid-January, and early February. Lett. This is usually because of two primary factors: 1. Climate Outlook | Office of the Washington State Climatologist Western Washington got more rain and snow compared to average, with Snoqualmie reporting their highest snow depth in 10 years. La Nina winter weather in Seattle | king5.com Snow lovers are unlikely to be pleased as were projecting below-average amounts for the fifth time in the past six winters. Street Departments We are currently in the midst of a very persistent negative PDO period. Precipitation tends to be below-average across the southern tier of the United States and wetter than average across the Pacific Northwest and Ohio Valley. WASHINGTON The Farmers' Almanac just released its 2021-22 winter forecast, and it predicts Washington is in for a fairly normal pattern. Its calling for above average temperatures and below-average snowfall (5 to 13 inches), in line with everyone elses expectations. Note that monthly temperature predictions are less reliable than for the whole season. When La Nia develops across the tropical central/eastern Pacific Ocean, it can affect areas thousands of miles away, including the United States. And like for seasonal temperature and precipitation, knowing the state of ENSO is a pretty reasonable place to start. Are you ready for the upcoming winter season? The price of natural gas sold to Nevada ratepayers saw another unusually high spike in January 2023, hitting $36.81 per thousand cubic feet, up from $3.74 in January of 2021 and $7.45 in January 2022. Other climate phenomena, such as the Arctic Oscillation or the Madden Julian Oscillation, as well as the random nature of weather, can also play a large part in how winter turns out. The impacts of La Nina will likely be felt until early spring 2022. Strong MJO activity often dissects the planet into halves: one half within the enhanced convective phase and the other half in the suppressed convective phase. This video and related map images can also be accessed at www.climate.gov/WinterOutlook2021. A negative AO in the winter months often correlates with a cold pattern in our region, and supports winter storms when other factors align with it, particularly when we have a negative NAO as well. For the MJO to be considered active, this dipole of enhanced/suppressed convective phases must be present and shifting eastward with time. This picture is consistent with long-term warming trends in the United States. While a negative AO and NAO combination far from guarantees a cold and snowy period, our chances of a meaningful snow event are much greater than without it. Warmer-than-normal temperaturesare favoredacross the southern and eastern United States. Washington State Dept. We expect there will be multiple windows when both indexes link up and go sharply negative, enhancing our chance for snow events. 2023 Housing Market Predictions and Forecast - Realtor.com La Nia refers to abnormally cold water temperatures across the central and eastern equatorial waters (5N-5S, 120-170W)] of the Pacific Ocean. Viewed from above either pole, these patterns show a characteristic ring-shape or "annular" pattern; thus, AO and AAO are also referred to as the Northern Annular Mode (NAM) and Southern Annular Mode (SAM), respectively. However, considering there have been 23La Nias since the winter of 1949-50, this is a very small sample size. (2015b) for more details. Because of the uncertainty involved, we give ranges and attempt to be as transparent as possible in conveying that these outlooks are indeed low-confidence. La Nia and El Nio is a an observation of ocean temperature anomalies near the equator in the Pacific Ocean that can have a direct impact on weather patterns globally. Locally,wetter-than-normal is slightly favoredinsoutheast Minnesota, northeast Iowa, andwestern Wisconsin. Theseries of maps to the right shows temperature patterns across the continental United States compared to the 1981-2010 average for every winter seasonDecember through Februarysince 1950 that coincided with La Nia conditions in the equatorial Pacific Ocean. Sci.,29, 1109-1123. Time Zone. WASHINGTON The Farmers Almanac just released its 2021-22 winter forecast, and it predicts Washington is in for a fairly normal pattern. Here's the FOX 5 Winter Weather Outlook! The typical U.S. impacts are warmer- and drier-than-average conditions across the southern tier of the United States, colder-than-average conditions across the north-central Plains, and wetter-than-average conditions in the Pacific Northwest stretching into northern California. Notice how the shading returns to the same location on the order of about 45 days. The early arrival of the winter storms will also spell an end to the active wildfire season for the region as rain and snow help to douse any flames. Notably, the forecast calls for: The Great Lakes and Northeast can expect potent winter storms heavy snow, rain or a wintry mix of both during the second week of January, the final week of February and the second week of March. Forecast Discussion The greater the difference, the stronger the La Nina is and more likely it is to influence weather patterns. When it is strongly positive, it often correlates with a cold and stormy pattern for the Mid-Atlantic. Since initiating these outlooks, our best winter forecast preceded the record-breaking Snowmageddon winter of 2009-2010, when we said: Overall, we find chances for a large snowstorm of 8-12 inches or more are much higher than normal this coming winter. Our outlook for the winter of 2014-2015 was also quite successful, as we correctly called for it to be cold with somewhat above-normal snow. Over Indonesia, there is more rising air motion and lower surface pressure. The precipitation pattern, presented above, shows negative anomalies (indicating below-normal rainfall) across the entire southern part of the country with a weaker signal of above-average precipitation in the Ohio Valley and in the Pacific Northwest and the northern Rockies. However, tornado and severe weather activity is more variable (noisier and harder to predict) than ordinary weather (think temperature and precipitation), and any ENSO signal is harder to see. where snowfall is greater than average and brown shows where snowfall is less than average. Early February should also start rather cold and stormy, but the month looks to end on the warmer side. Fiscal Forecast America: Farewell to State Independence Climate.gov drawing by Fiona Martin. NOAA's 2021-2022 Winter Forecast | OpenSnow Drier-than-average conditions are favored across the southern United States, and southeast Alaska. Here's what a 'double dip' La Nina winter means for Washington April and May will be warmer and slightly wetter than normal, on average.
