As far as ENSO goes the one difference this winter seems to be the east tropical Pacific was not as cold as the prior years when the SSTs in the Nino 1.2 at times were from -2 to -.2.5 while the western tropical pacific was near neutral. Sunshine and showers on Sunday. Fast, informative and written just for locals. Alex Burkill, senior meteorologist at the Met Office, said: Its likely to be the warmest spell weve had at the end of October since 2014, when we had the warmest Halloween on record. We dont end up with enough events in each group, and the noise of chaotic weather variability hides the signal we are trying to identify. The National Oceanic and Atmospheric Administration says its own five-day forecast is accurate about 90% of the time and seven-day forecast 80%. Here is what the Met Office is predicting for the coming weeks. 2022-2023 Winter Weather Forecast | ACHR News We did have a high-amplitude MJO phase 3, which often leads to wet conditions on the West Coast. This will be followed by the Quadrantid Meteor Shower . Despite the headlines, the winter weather predictions from both publications have a lot of similarities this year. 4th grader reports Friday's weather forecast 1 day ago. 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 Southern Plains. Conditions will be particularly cold through the middle of the month, with widespread frosts and a risk of wintry showers, even to low levels in some cases. The figure below shows that most (13 of 21) of the La Nias from 1951-2020 had below-average December-January precipitation in this region (1), although wet early winters during La Nia . Cold weather to arrive this weekend, bringing wintry showers to Scotland, Nanoplastics now ubiquitous in air, water and soil, says new report. We see an increased snow potential over the upper Midwest, with some other areas across the Midwest having normal snowfall amounts forecast this month (0/white areas). Three events went neutral in the third year, and three phases shifted into an El Nino in the third season. The image shows the average jet stream position in La Nina winters and the resulting weather patterns developing over the United States and Canada in a cold-ENSO dominant Winter. Tonight should be the chilliest for a while. How harsh will winter be? I first averaged the 30 simulations for each of the 21 La Nia winters, giving me 21 precipitation outcomes. Forecasts hint at abnormal UK winter: whats the long-range outlook? That total is deceptive as many areas in Tucson area had 6-7 inches today, Meanwhile Washington DC and Philadelphia have had less than 1/2 inch snow this winter, Submitted by Craig T on Thu, 03/02/2023 - 16:22. With the observations, I did try setting a higher La Nina amplitude threshold (DJF Nino 3.4 SST anomaly amplitude greater than 1 deg. This was an interesting post that gave more insights into how La Nia can influence winter precipitation in the Southwest, and how it's more complex than stating that its presence means it'll be dry. Below-normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes. The almanac, which releases an annual long-range. Farmers' Almanac Releases an Extreme Winter Forecast for 2022-23 The most important ingredients for snowfall are the air being cold enough and a supply of moisture. Rare 'Triple-Dip' La Nia Increasingly Possible - The Weather Channel I follow that convention here, though Im really calculating the inverse, meaning the noise-to-signal ratio. Enjoy summer while you can, folks because Ontario's 2022 winter weather forecast is shaping up to be a real drag. Submitted by rebecca.lindsey on Thu, 02/23/2023 - 10:32. But otherwise, the rest of the continent shows less snowfall than normal for this month. NOAA's 2022-2023 Winter Forecast | OpenSnow All good scientific studies note their limitations, and this analysis carries some caveats that are familiar to most climate scientists. Precipitation-wise, La Nina winters are usually drier over the southern United States. That's why Nat used model simulations to look at the relationships here, finding that there's no preferred pattern to the sea surface temperature for wet SW winters. Lets turn the Farmers Almanac into something real and useful. In this blog post, I hope to get this conversation rolling! When we divide up the observed record even further, e.g. By weather.com meteorologists October 13, 2022 At a Glance A generally colder than usual winter is expected in the northern tier of states. Hello climate.gov administrator, You always provide in-depth analysis and understanding. I did just one set of analyses focused on one particular region with one climate model, and thats why I stated up front that this is just the start of the conversation. Average DecemberJanuary precipitation anomalies (percent of the 1991-2020 climatology) for all La Nia events from 1951-2020, defined as La Nia occurring in DecemberFebruary. Submitted by Nathaniel.Johnson on Sun, 02/26/2023 - 20:08, In reply to Thanks Nat for this cogent by Clara Deser. Follow severe weather as it happens. The December snowfall forecast shows some areas with more snowfall over northern, western, and central parts. The rest of the United States shows less snowfall than normal, but that does not mean no snow at all. This latest forecast cycle interestingly shows more snowfall over the western United States and also the Midwest. So, the bottom line is that the relationship between La Nina amplitude and Southwest U.S. precipitation does not appear as simple as one (or at least I) would expect based on this analysis, and it's something I would like to understand better. It's important to keep in mind that not every location in the Southwest has been wetter than normal lately. WINTER SEASON 2022/2023 FIRST LOOK FORECAST - Severe Weather Europe My question, regarding the un-forecast DEC/JAN 2022-23 is whether the heavy precipitation was contributed to by the unusual presence of warming near and east of the Dateline referred to by NOAA as "warm blob" NEP22A and NEP23A? This does not mean there will be no snow, but it indicates less snowfall than normal. Historically, a strong blocking high-pressure system in the North Pacific is the most typical effect of a cold ENSO phase. Farmer's Almanac Winter 2021-2022 Predictions by Region - Martha Stewart Feeling cold. We cannot rule out the possibility that the model is missing some sort of predictable connection between a particular flavor of La Nia sea surface temperatures and Southwest precipitation. Get The 7 DMV newsletter in your inbox every weekday morning. Finally, the persistently positive SOI and MEI is an interesting observation. Submitted by Craig T on Thu, 03/02/2023 - 18:31, In reply to forecast busts by Nathaniel.Johnson, Submitted by Nathaniel.Johnson on Fri, 03/03/2023 - 10:31, Minor correction.

That forecast extends to some popular California ski resorts. Next, I tackled the noise part of the calculation, which represents the Southwest precipitation variations that are unrelated to the sea surface temperature patterns. Images by NOAA Physical Science Laboratory. Rain, heavy at times, will sweep quickly north-eastwards across most parts. As a snow lover, I am jealous of Flagstaff residents, though I suppose many of those residents have a different perspective than I do. A person clears their car of snow to go to work, in Provo, Utah, on Feb. 22, 2023. Turning wet and windy from the west on Monday. Minnesota winter 2022-23 report card: Wettest on record and mild An official website of the United States government. As I watch another 2 feet of snow fall today in what is now the wettest winter in Flagstaff in 30+ years, a couple things stand out: The active MJO clearly has been a bigger influence on West Coast and SW weather this season. The first day of winter and the shortest day of the year, officially arrives on December 21, 2022, but that doesn't always mean that the cold temperatures and snow storms will wait until then. The greatest chance for warmer-than-average conditions are in western Alaska, and the Central Great Basin and Southwest extending through the Southern Plains. (Head to footnote 6 for all the gory math details.). The Met Office adds: What about the moisture? One exception is southwestern Canada and higher elevations in the western/northwestern United States. Winter 2022/2023 Snowfall Predictions: Final Snow Forecast for the There are also some hints of a cold event reaching down to the south-central United States. As that post notes, it's critical to understand the source of the mismatch models and observations (natural variability or model error or both? The forecast, which actually was released earlier than usual this year amid "growing concern over the rising costs of heating oil," warns that this winter will have people across much of the country "shaking, shivering, and shoveling." Northerly winds (i.e. Sea Surface Temperature AnomalyDecember 2010. However, climate scientists continue to investigate this topic, and hopefully we will have greater scientific consensus in the years ahead. The pattern in the map is very weak, with very small departures between the two groups. Drought improvement in the Southwest continues As of July 26, 2022, over 50% of the contiguous U.S. was in drought, with almost 20% in the two worst categories, extreme and exceptional drought (D3-4), a slight increase since late June. Hot Chocolate Warning In The East and South Instead, the pattern looked a bit more like the positive phase of the Pacific Meridional Mode. Summer Forecast 2022: Sizzling Summer Ahead - Farmers' Almanac - Plan Despite the rocky end of the year, Southwest reported a $539 million profit for 2022. The Farmers Almanac says temperatures in the Southeast and Northeast should become milder in February, though. The Met Office explains: To get cold air across the UK we need winds from the north or east. Ohio Winter Forecast 2022-2023 - Earth Development How harsh will winter be? Six organizations issue forecasts. When we plug those values in, we get (0.725)2/(0.194)2 = 14, which is why I conclude that chaotic weather variations are about 14 times more important than the variations caused by sea surface temperature variations for December-January Southwest U.S. precipitation during La Nia events. Quite unusual! The effects of air rising up hills and mountains must also be considered. Winter Weather Forecast for 2022 - 2023 | From Direct Weather What AccuWeather's 2022-23 winter forecast says about Minnesota December is favored to be the chilliest month on the Eastern Seaboard, with lower-than-normal temperatures expected from the Great Lakes down into parts of the Mid-Atlantic and Northeast. ), and I have seen that there are a few studies that point to processes around Antarctica that could be contributing.

View the weather with our interactive map. In the January forecast, there is no real improvement. In line with December's blocking high pressure, the lack of weather fronts moving in from the Atlantic mean the month is expected to be much drier than average for western areas, especially in Scotland. We know that all La Nias feature below-average surface temperatures in the central and eastern equatorial Pacific, by definition, but the details vary from event to event. The question is, whats different about those years? 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. La Nina is a climate pattern that originates in the Pacific Ocean but impacts the global weather forecast. The December snow depth forecast shows widespread negative anomalies. More snowfall is still forecast in the upper Midwest, with some hints of more snowfall around the central Great Lakes. We can run multiple simulations in which the ocean is always the sameforced to match observed sea surface temperatures, including all La Nias from 1951-2020but the starting atmospheric conditions are very slightly different each time. Although such climate models are rather sophisticated and reliable, they are imperfect.

A somewhat subjective rating of the day's weather, on a scale of 0 to 10. What does the latest ocean analysis data show, and what influence did it play on temperature and snowfall patterns in the past? Above all thank you for the richness of the information but i take note that some (data simulation methods) may tend to under-estimate (under fit) and others may overestimate (over-fit) an ulterior assumption , choosing the best ( mathematical) simulation methods may sometimes tell a good tale even with the presence of short data window . And did tropical sea surface temperatures contribute?

Winter Outlook for West Central and Southwest Florida 'Unreasonably' Cold: Farmers' Almanac Winter Forecast For VA 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. Turning to Slide 5. Also, CPC data reveals an East Pacific MJO episode in January. Submitted by Ed Ratledge on Fri, 02/24/2023 - 13:30. 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. NOAA releases Winter 2021/22 Outlook: How much cold and snow - WFXRtv Its conceivable that such differences could influence precipitation in the Southwest U.S., but these differences are much smaller than the amplitude of the largest average La Nia tropical Pacific sea surface temperature anomalies, which approach 2 Therefore, it is difficult to see how such small sea surface temperature differences could have an influence that is comparable with the average La Nia influence. But if these big picture findings hold up to further scrutiny, then it means that the typical or averaged La Nia precipitation pattern still may be the most reliable guide for seasonal predictions of Southwest precipitation in early winter, but we may have to rely on subseasonal and weather forecasts rather than seasonal outlooks to anticipate the sort of soaking that occurred in December and January of this winter. C) and did not see any substantial differences than when I considered all La Nina episodes. Below normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes and the Alaska Panhandle.

This will most likely result in wintry showers, these turning more organised at times in the north and east. By January, most of the country is mild, with lower temperatures farther north and a serious chill entering the Upper Midwest and Great Lakes region by February, while the Southeast especially toward Florida, warms up. Heres what that means. This way, the ENSO significantly impacts tropical rainfall and pressure patterns, strongly changing the atmosphere-ocean feedback system. The ENSO blog is written, edited, and moderated by Michelle LHeureux (NOAA Climate Prediction Center), Emily Becker (University of Miami/CIMAS), Nat Johnson (NOAA Geophysical Fluid Dynamics Laboratory), and Tom DiLiberto and Rebecca Lindsey (contractors to NOAA Climate Program Office), with periodic guest contributors. Below, you can see the progress of some historical multi-year La Nina episodes, with only two events previously having a 3rd-year event. The southern United States is forecast to have a drier-than-normal winter season. 7 day. During the years of 2022, 2023, and 2024, an event like no other struck the ENTIRE United States, unleashing total chaos upon the country. I need a storm to track south of me without occluding for once. This connection has been hypothesized, but the evidence is mixed. WARNING: Long-range forecasts are rarely accurate. That means that most teleconnection patterns that influence U.S. climate are what we consider "internal to the atmosphere" and tend to grow and decay on time scales of a couple of weeks. 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). We received 6.45 inches of precipitation (that includes snowfall as liquid equivalent), which is a whopping 3.53 inches above normal - more than double the .
