Apparently 24 years ago the NWS office for Flagstaff moved from the airport to a community(Bellemont) just west of Flagstaff. Thanks for doing those simulations, and for sharing the results here. The official NOAA Temperature outlook points: The official precipitation forecast is also quite similar to the latest model forecasts. Places where precipitation was less than 100 percent of the 1991-2020 average are brown; places where precipitation was 300 percent or more than average are blue-green. How harsh will winter be? 2022-2024 "Arctic Hell" Storm - Hypothetical Disasters Wiki Also, CPC data reveals an East Pacific MJO episode in January. It relocates the jet stream downwards between the two strong pressure systems, marked above by the blue lines. An important global weather factor is ENSO. AccuWeather says that the lingering water vapor in the atmosphere from the eruption could cause a warmer winter than normal but that the magnitude of the effect is unknown. I am no scientist. We can also track snowfall potential on normal temperature and precipitation Winter forecasts. So what exactly does this mean for the winter weather patterns and snowfall potential? More U. S. drought in a second-year La Nia? Warmer-than-average temperatures are favored in the Southwestern United States, across the Southeastern states, and along the Atlantic coast. The southern half of the country has a higher probability of warmer than normal weather. Biden set for first veto on Senate bill opposing climate-friendly investing, Global carbon dioxide emissions hit new highs last year, says IEA report, Young women are criticized for this vocal tic but it helps whales survive, winter outlook from WeatherBell Analytics. This figure indicates that SPEAR produces very wet early winter conditions in the Southwest for some of the La Nia simulations, with the largest differences between the wet and dry groups exceeding twice the 1991-2020 climatology (more than 200%). Starting with the seasonal average for Europe, we can see another weak snowfall forecast similar to the ECMWF. Next, I tackled the noise part of the calculation, which represents the Southwest precipitation variations that are unrelated to the sea surface temperature patterns. Submitted by Nathaniel.Johnson on Thu, 02/23/2023 - 17:47. Resources such as drought.gov and climate.gov provide comprehensive tools to better understand and plan for climate-driven hazards. This U.S. Winter Outlook 2021-2022 map for temperature shows warmer-than-average conditions across the South and most of the eastern U.S., while below average temperatures are favored for southeast Alaska and the Pacific Northwest eastward to the Northern Plains. 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. Finally, do you have any comment on the unusual persistent La Nina-like SOI and multivariate ENSO index (MEI) for the 2020-23 La Nina despite occasional neutral Nino34 SSTA lapses? The Met Office has warned that snow may appear across the north and west of the UK as early as 9 November. Rick Wiley / Arizona Daily Star Facebook For example, we can see a list of teleconnection patterns monitored by CPC, and I believe that only the PNA and TNH have a strong connection to ENSO among that list. The million-dollar question for seasonal forecasters and climate scientists alike is whether this unusually wet Southwestern U.S. could have been anticipated more than a few weeks in advance. Of course, as with all these predictions, they are just indications of the long-range patterns. A major weather divide is int he forecast. Cold weather to arrive this weekend, bringing wintry showers to Scotland, Nanoplastics now ubiquitous in air, water and soil, says new report. The greatest chances for drier-than-average conditions are forecast in portions of California, the Southwest, the southern Rockies, the southern Plains, the Gulf Coast, and much of the Southeast. Categories Long range / seasonal forecast. These are blog posts, not official agency communications; if you quote from these posts or from the comments section, you should attribute the quoted material to the blogger or commenter, not to NOAA, CPC, or Climate.gov. Overall, the UKMO shows a decent snow season across the northern United States. Here is the forecast for the coming days. Last month was. ECMWF data provided is provided by the Copernicus-EU open project. You can see that jet stream redirection in the image below. I will just add that I only focused on one impact and one particular region (Southwest U.S. precipitation), but it would be interesting to do a more comprehensive analysis of possible distinctions between La Nina flavors in the climate model simulations. The season will be relatively normal this year. The exact value may change depending on what metric you use, but the overall conclusion shouldnt change. The Farmer's Almanac Winter 2022-2023 Forecast Is Here 2022-2023 Winter Weather Forecast | ACHR News Submitted by Nathaniel.Johnson on Tue, 02/28/2023 - 15:50. But note more snowfall potential remains over the u pper Midwest. 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. This year, La Nia is forecast to prevail for a third straight winter. Fortunately, right on cue, the Farmers' Almanac has released its 2022/2023 winter weather forecast. Most areas dry, breezy and very mild, though a few showers perhaps affecting southern England for a time. 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 . 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 . Winter Forecast for Southwest Michigan for 2022/2023 Impactful Winter Weather On the Way A storm system will move into Lower Michigan for Friday, bringing primarily snow but some light freezing rain could mix in across the far south. Higher temperatures are forecast for the West; WeatherBell projects temperatures 1 to 3 degrees above normal in the Southwest. 8/10: A new . The snowfall forecast focuses the most snowfall on the Midwest. In the Southeast, the Farmers Almanacs expected East Coast storms are more likely to bring rain, although chilly conditions that enter the region in January could cause wintry precipitation there, as well. Typically there is a phase change around every 1-3 years. 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. Thank you for your question! These temperatures ranged from near-normal to 4F warmer than normal. WARNING: Long-range forecasts are rarely accurate. Images by NOAA Physical Science Laboratory. The almanac, which releases an annual long-range. Here, I am focusing on the Southwest region south of 40 N that covers most of California, Nevada, Utah, and Arizona, in early winter (DecemberJanuary). Historically, a strong blocking high-pressure system in the North Pacific is the most typical effect of a cold ENSO phase. The rest of the United States and eastern Canada are expected to see less snowfall in the early spring. December-February: January-March: The logical conclusion is that, according to the climate model, unusually heavy Southwest U.S. precipitation during December-January of La Nia has very little to do with the sea surface temperatures and instead is more closely tied to short-term and seasonally unpredictable weather conditions, as captured by the variations among the 30 simulations for a given La Nia. I saw this same behavior in my analysis of the SPEAR climate model simulations, which increases confidence that this more robust dry signal in February-March is a real phenomenon. The UK winter weather forecast 2022/2023 Unfortunately, a dry winter is predicted for the Southwest states, which won't help the drought situation. The southern United States is forecast to have a drier-than-normal winter season. This is only the 2nd time there has been above normal winter rainfall, Submitted by Craig T on Thu, 03/02/2023 - 08:09, In reply to jet stream by Nathaniel.Johnson. The widely followed youtube weather channel, is calling for a mixed bag of weather this upcoming winter season. That part of the country also is expected to receive less snow than normal. The UK is set to be hotter than Greece over the weekend as the countrycontinues to experience unusually warm temperatures this October. Hourly. The Euro precipitation forecast outlines the major areas of concern with our snowfall outlook. My conclusion: the chaotic weather variations are about 14 times more important than the variations in La Nia amplitude or flavor for Southwest U.S. precipitation, which is consistent with the figure above. We are currently in a La Nina phase, entering its third and final year, likely being replaced by a warm phase for 2023/2024. This is mainly a result of warmer-than-normal temperatures expected in late Winter by UKMO in the south/southwest. So, next, we want to know if there are any consistent differences in the sea surface temperature pattern between La Nias that lead to wet versus dry early winters in the Southwest. Submitted by Nathaniel.Johnson on Thu, 03/02/2023 - 17:00, In reply to Southeast Colorado and Northeast New Mexico by Tony Arnhold, Science & information for a climate-smart nation, torrential rains and heavy mountain snows, NOAAs Precipitation Reconstruction over Land (PREC/L). .

We can also see more snowfall hinted in this run over southern Great Britain. Note that even the most scientifically advanced seasonal outlooks cannot pinpoint what the weather will be in a particular place at a particular time this far in advance. Wetter-than-average conditions are most likely in western Alaska, the Pacific Northwest, northern Rockies, Great Lakes and Ohio Valley. Everything I read details how little we understand and have modeled such an occurrence- a gigantic and long-lasting (it will take years for the extra water vapor to dissipate) change to something that we think of (and model) as utterly constant and stable. That can be interpreted as a potential route of winter cold air outbreaks down from the Midwest to the south, creating occasional snow events. 16 day. CPC Outlook for Winter 2022-23: The overall forecast for West Central and Southwest Florida for the upcoming winter is for a better chance of above normal temperatures and below normal rainfall as can be seen in the Climate Prediction Center Winter Outlook graphics below. Because the observed record is too short to tease out the relationships we seek with sufficient precision, we rely on climate models to sharpen the signal relative to the noise of random weather variability. Want to learn more about the Weather? travelling for the east to the west) are cold because they arrive from the cold continental interior of mainland Europe. The cold phase is called La Nina, and the warm phase is called El Nino. NOAA releases Winter 2021/22 Outlook: How much cold and snow - WFXRtv Six organizations issue forecasts. This will most likely result in wintry showers, these turning more organised at times in the north and east. Here, I am focusing on the Southwest region south of 40 N that covers most of California, Nevada, Utah, and Arizona, in early winter (December-January). Since the latest forecast data was released in mid-late November, we now also have the March data included, so we can look at some early Spring snowfall potential. Ontario's 2022 Winter Weather Forecast Is Here & You're Gonna Need A 2022-2023 Winter Forecast Preview | OpenSnow 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. But otherwise, the rest of the continent shows less snowfall than normal for this month. 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. The start of this period is expected to be characterised by winds from the north bringing cold conditions to most areas with widespread frost and ice. We'll let you know if/when he does! Winter 2022/2023 Snowfall Predictions: Final Snow Forecast for the One of the main features of the UK's weather this year has been the seemingly indomitable prevalence of mild conditions, which has catapulted 2022 into strong contention for the warmest year on record. You can see that more snowfall is being forecast across much of the western United States compared to the previous forecast. 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 clearly are not that unusual. Ohio Winter Forecast 2022-2023 - Earth Development ENSO phases significantly influence tropical rainfall, pressure patterns, and the complex exchange between the ocean and the atmosphere. Hopefully Nat will have a chance to turn this into a paper, but it will have to wait for a lull in his schedule. Their precip map show wetter that normal conditions for California during these types of events. Europe features mostly warmer than normal conditions over northern parts, with a storm track over the southwest . Thanks for your questions. La Nia could enter rare third straight year.

That means forecasts will bust from time to time, and success or failure must be evaluated over many forecasts. Most of the continent is forecast to have less snowfall than normal, except for far northern Europe. In the East, the almanac predicts above-average snowfall for a vast area, from North Carolina to central New England to the Ohio and Tennessee Valleys, as well as the Great Plains. This does not mean there will be no snow, but it indicates less snowfall than normal. 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. air travelling from north to the south) bring the air straight from the Arctic and over a cold sea to reach the UK. Temperatures overall will be below average but may gradually trend up later. Most of Europe is forecast to have less snow depth by mid-winter. Above-normal precipitation is forecast in part of the Ohio Valley, an area that could pick up above-normal snowfall if temperatures remain low enough. But now, we will look at actual Winter snowfall predictions from the latest forecast models.

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. 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. 2022-2023 California and Southwest Weather Thread However, we still need more analysis to see if the particular sea surface temperature pattern this year played some role, including the unusual frequency of atmospheric rivers. Difference in DecemberJanuary precipitation anomalies (percent of the 1991-2020 climatology) between the wettest 20% and driest 20% of Southwestern U.S. La Nia outcomes simulated by the GFDL SPEAR climate model. Farmers' Almanac predicts Michigan winter with plenty of snow, cold La Nina: What to expect from the return of this climate pattern - USA TODAY 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). However, December may put the brakes on this, with a strong signal for this month to be much cooler than average. The ENSO influence is spread globally through this feedback system, creating different Winter temperature and snowfall patterns. Warmer and drier winter weather prevails over the southern states. We always focus on trends and probabilities, but still, variation is key. Annual and monthly snow totals at MSP Airport since 2011-12. TUCSON, Ariz. (KGUN) March marches in like a lion!

From the abundance of acorns in the fall to the bushiness of squirrel tails, there are many fanciful forecasting techniques have been used over the years as a means to glean a glimpse of what the weather will be like in the upcoming winter. However, I would not rule out that there could be a minor influence, especially with NEP22A, since those anomalies are in a region that did seem to provide a minor enhancement to Southwest precipitation in the simulations I analyzed. The most common wind direction in the UK is south-westerly though, so more often than not we get relatively mild air from the Atlantic bringing rain, rather than this cold air from the north and east which often turns any rain to snow..
