The National Oceanic and Atmospheric Administration says its own five-day forecast is accurate about 90% of the time and seven-day forecast 80%. It calls for snowfall to be above normal toward the East Coast as well. The Met Office has warned that snow may appear across the north and west of the UK as early as 9 November. Verification, impacts and post-processing, Climate information for international development, Science for Impacts, Resilience and Adaptation (SIRA), Atmospheric processes and parametrizations, Regional model evaluation and development, Environmental Hazard and Resilience Services, National Meteorological Library & Archive. Here are some useful tips. The blue bars indicate the chance of La Nia for each three-month period into winter 2022-23, according to this forecast from early May 2022. . We can also see more snowfall hinted in this run over southern Great Britain. I also have noted that the tropical atmosphere has been more persistently La Nina-like than the Nino region sea surface temperatures in recent months. If there is one basic theme I've learned from all the postings on this blog is that our climate is very complex with many different parts and ENSO is just one big part of it so there is always going to make any winter outcome far from certain. Widespread extreme drought continues to persist across much of the West, the Great Basin, and the central-to-southern Great Plains. 30 forecast for Winnetka! Above-normal precipitation is possible in northwestern Montana, northern Idaho and northeastern Washington state. The Old Farmers Almanac is predicting a divided nation with harsh winter in the East and mild weather in the West. Thanks, Tom. The Met Office notes that the UK being an island makes snow far less frequent than in mainland Europe. As we discussed in this post, La Nina typically causes a reduction rather than increase in western U.S. atmospheric river activity. In turn, the NAO, PNA and AO combinations--some of which can be reasonably forecast on intraseasonal scales--demonstrate that some of our wettest winters can come in a La Nina year. The relief from an unrelenting drought was welcome, but too much of a good thing also meant flooding, mudslides, and dangerous debris flows. For completeness, I will mention that there are other potential sources of seasonal predictability, such as stratospheric, cryosphere, land surface or radiative forcing variations, but sea surface temperature variations generally are the most important. The U.S. Winter Outlook 2022-2023 map for temperature shows the greatest chances for warmer-than-average conditions in western Alaska, and the Central Great Basin and Southwest extending through . The pattern in the map is very weak, with very small departures between the two groups. So, I agree that we likely can point to specific factors contributing to this unusual winter, and it would be worthwhile to carry out a detailed attribution analysis. It will modify the jet stream pattern over North America and the Pacific Ocean, extending its reach to the rest of the world. Most of the continent is forecast to have less snowfall than normal, except for far northern Europe. Although such climate models are rather sophisticated and reliable, they are imperfect. A blog about monitoring and forecasting El Nio, La Nia, and their impacts. Starting in December 2022 through February 2023, NOAA predicts drier-than-average conditions across the South with wetter-than-average conditions for areas of the Ohio Valley, Great Lakes, northern Rockies and Pacific Northwest. Distribution of DecemberJanuary precipitation anomalies (percent of the 1991-2020 climatology) in the Southwest U.S. (region defined in the figure above) for all 21 La Nias from 1951-2020. For this analysis, I am using simulations of monthly climate from the Geophysical Fluid Dynamics Laboratory (GFDL) climate model called SPEAR, the same model that contributes seasonal forecasts to the North American Multi-Model Ensemble (NMME), but here the experiment is designed to analyze the climate effects of the observed sea surface temperature evolution from 1951-2020 (4). The UK is set to be hotter than Greece over the weekend as the countrycontinues to experience unusually warm temperatures this October. Between 2013 and 2022, we delivered an organic revenue CAGR of 11. . With snow accumulation up to 88 inches, and entire summers with temperatures below freezing, the northern hemisphere was rattled with Satan's snow. Events were the coldest temps are in the central pacific and warmer temps in the east. Submitted by Nathaniel.Johnson on Thu, 03/02/2023 - 09:50, In reply to Other teleconnections by Stan Rose.

Submitted by Nathaniel.Johnson on Wed, 03/01/2023 - 19:55, In reply to Atmospheric rivers by Jiwon Kim. The MJO certainly can interfere with ENSO, particularly during development of ENSO through the MJO influence on tropical westerly wind bursts. But note more snowfall potential remains over the u pper Midwest. But in general, AccuWeather is predicting a season of less snowfall on the Eastern Seaboard. Besides the northwestern United States and the Midwest, we can see more snowfall potential over the northeastern United States and eastern Canada. One way we could try to address this question is to group both the wettest and driest La Nias over the Southwest in December-January and then see if there are notable differences in the sea surface temperature patterns that occurred during wetter La Nias versus drier La Nias. Typically there is a phase change around every 1-3 years. Typically, the first influence of these ocean anomalies can be seen in the jet stream patterns changing. There will be a chance to catch the last major meteor shower of 2021 just before Christmas, with the Ursids peaking on December 22 and 23. The Farmers Almanac predicts that across the region, March will go out like a lion, with a variety of conditions, including heavy snowfalls, heavy rain and gusty thunderstorms. This atmospheric river onslaught surprised many who were expecting a dry season, especially in the Southwest, not only because of the prolonged drought, but also because La Nia tends to bring drier-than-average winter conditions to the region. Ideas and explanations found in these posts should be attributed to the ENSO blog team, and not to NOAA (the agency) itself. I am no scientist. The February snow depth forecast shows continued increased snowfall potential over the northwestern United States and expanding over western and southern Canada. I also agree that relying on ENSO indices for a seasonal forecast is a recipe for a busted forecast, particularly IF the forecast is not interpreted correctly. It says that temperatures there could drop 4 degrees below normal for the month something that could result in a damaged citrus crop and stunned iguanas. The rest of the United States is forecast to receive less snowfall than normal this month, with the expectation of the far northeastern United States and parts of the southeast. Could the jet stream also have influenced precipitation amounts ? I also like the idea that MJO may have been a factor, BTW I am not a weather scientist just a life long weather geek, Submitted by Craig T on Tue, 02/28/2023 - 20:15. I agree, a very interesting post! This area is still feeling theeffects of the past 3 VERY Dry Winters. This is referring to the kind of divide where one half of the U.S. could be blistering cold, while the other will be so mild. We will look at two highly regarded seasonal weather forecasting systems. Rishi Sunak set to unveil new laws to tackle small boat crossings in Channel next week, Government WhatsApp decision-making threatens 'accountability', warns Information Commissioner, Snow and ice warning as coldest day of year so far to hit UK as temperatures plummet, continues to experience unusually warm temperatures this October, 'How bad are the pics? The February snowfall forecast shows snowfall potential remaining over the northern parts of the United States. As the figure above shows, much of the western U.S. was pummeled from late December through mid-January, as a series of nine atmospheric rivers dumped more than a seasons worth of rain and snow in a few short weeks. 4th grader reports Friday's weather forecast 1 day ago. It was also noticeable that most mediterranean-like climates in both ( North and South) hemispheres had shown early signals of drought in December-January Projections from last year , the coupling of a negative ENSO and negative PDO with Negative IOD brings limited number of Lanina years with such combined wet-dry phases during a particular ENSO ( cold or warm ) . Difference in DecemberJanuary sea surface temperature anomalies ( C) between the wettest 20% and driest 20% of Southwestern U.S. La Nia outcomes simulated by the GFDL SPEAR climate model. Its interesting to note that the La Nia dry signal over the Southwest U.S. appears to be a little more robust in February-March than December-January, as 15 of the 21 events classified as La Nia in December-February had drier-than-average conditions in February-March. AccuWeather's range for the Twin Cities is 75-124% of normal, which means it could be below average or above average. And did tropical sea surface temperatures contribute? Share sensitive information only on official, secure websites.. Snow-covered field in Kansas. As its normally colder higher up in the atmosphere, when the air rises up a hill, it becomes colder, and condenses to form cloud and precipitation. New for the 2023 edition are weather summaries and maps for all four seasons in 2023. AccuWeather forecasters are predicting a more active severe thunderstorm season in the southeastern states during the winter months because of warmer-than-normal ocean temperatures. Dont miss the full Winter forecast with pressure and temperature patterns: Winter Forecast 2022/2023 November Update: Cold ENSO phase peaks, with its growing weather influence as we head for the start of the Winter Season, Snow Extent in the Northern Hemisphere now Among the Highest in 56 years Increases the Likelihood of Cold Early Winter Forecast both in North America and Europe, Weather: A significant double-blocking pattern will bring a cold Winter start in December, disrupting the circulation and unlocking the cold air. Drought development is expected to occur across the South-central and Southeastern U.S., while drought conditions are expected to improve across the Northwestern U.S. over the coming months. You can see a strong snowfall anomaly over the Midwest and the Great Lakes, expanding over the northeastern United States. The colder air is more easily accessible to the northern United States, which increases the snowfall potential if enough moisture is available. It looks like an interesting study, and it relates to last month's blog post on the discrepancy between observed and modeled Pacific sea surface temperature trends. During the meteorological winter (December 1 through February 28) of 2022-23, average temperatures ranged from 16.7F at Medford, WI (COOP) to 25.7F at Boscobel Airport, WI (ASOS). Finally, the persistently positive SOI and MEI is an interesting observation. Jasmine Blackwell,jasmine.blackwell@noaa.gov, (202) 841-9184, Drought to persist in Great Plains, parts of West and expand, Audio: October 20 virtual media briefing on Winter Outlook 2022, National Oceanic and Atmospheric Administration, U.S. Winter Outlook: Warmer, drier South with ongoing La Nina. From February to April, above-normal temperatures are projected to continue along the East Coast, in the Southeast and into the Southwest, with the greatest chance of warmer weather along the Mid-Atlantic and Southeast coastlines as well as parts of the Southwest. That tends to redirect the polar jet stream down over the northern United States, with the cold air following. The prevailing Northeast Monsoon typically persist s until late March 2023 in the ASEAN region . Glasgow and Belfast are predicted to reach 16C, although this could be followed by a period of more typical October weather. Unfortunately, a dry winter is predicted for the Southwest states, which won't help the drought situation. Everything you need to know about the forecast, and making the most of the weather. This is all thanks to blocking high pressure to the north-west of the UK, which will prevent low pressure bringing mild air from the west and will instead favour colder air from the north and east. It was the largest snowfall of the season so far for Halifax and other communities of Nova Scotia. I don't have an explanation except to speculate that the multidecadal enhancement of the zonal sea surface temperature gradient (like what was described in this post) is helping to keep the tropical atmosphere more La Nina-like even when the typical ENSO sea surface temperature indexes are deviating from typical La Nina values.
