NOAAs new supercomputers are enabling us to develop even better, more detailed forecast capabilities, which well be rolling out in the coming years..
In this blog post, I hope to get this conversation rolling! First is the ECMWF, and then it is the UKMO. The Farmers Almanac says temperatures in the Southeast and Northeast should become milder in February, though. 7 day. Temperatures will likely fluctuate between cold and mild, north to south, but will probably average out around normal. 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). Those rainstorms may cause flooding in the Ohio Valley and along the Mississippi River, AccuWeather says. This will impact the Friday evening commute with delayed travel likely. Between 9 and 23 November there could be an increasing chance of settled weather from mid-month, bringing a potential for colder, drier weather especially for the north and west, it said. The coldest periods will be in late November, mid- and late December, and mid-January. Regions further east, on the other hand, will probably experience precipitation levels more typical for the time of year.

Want to learn more about the Weather? By that standing (since 1893), the meteorological winter of 2022-23 was the wettest in Minnesota. The effects of air rising up hills and mountains must also be considered. We have seen a stronger-than-normal jet stream throughout the Southwest, which has brought the wetter conditions this winter. The image below shows the circulation pattern of a cold phase and its ocean-atmosphere connection. Records back to 1893 are considered the most reliable and qualify for the "modern" record. 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. From February to April, below-normal precipitation is forecast in the Southwest and coastal portions of the Southeast, but areas including Texas may see a respite from less-than-normal snowfall and rainfall. The figure above shows the sea surface temperature differences between the high- and low-precipitation groups in the SPEAR simulations. The more forecast data you can look at, the better idea you can get about the expected weather patterns. A common approach to overcome this limitation of not enough real cases is to use global climate models to create hypothetical ones. 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. Drier-than-average conditions are forecast in portions of California, the Southwest, the southern Rockies, southern Plains, Gulf Coast and much of the Southeast. Durango Herald 3:40 AM MST on Mar 4, 2023. From the second half of next week onwards, milder conditions seem likely to push erratically north, with spells of rain and snow likely at times - which could be disruptive in places, at least at first. Unfortunately, a dry winter is predicted for the Southwest states, which won't help the drought situation. I follow that convention here, though Im really calculating the inverse, meaning the noise-to-signal ratio. 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. It relocates the jet stream downwards between the two strong pressure systems, marked above by the blue lines. 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 .

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. (NOAA Climate.gov, based on NWS CPC data). Below-average temperatures are forecast in the northern contiguous United States, stretching from northern Michigan to northern Washington state. 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. Areas depicted in white are regions where climate signals are weak and To analyze the effect of different sea surface temperature patterns on early-winter precipitation in the Southwest during La Nia, I first defined two groups: the wettest 20% and driest 20% of simulations. According to Flagstaff NWS website they gave so far had 146.7" snow this winter which blows away the previous record. That means forecasts will bust from time to time, and success or failure must be evaluated over many forecasts. The almanac forecasts cold and wet conditions down even into Florida, with the worst of the cold forecast for January. Submitted by Nathaniel.Johnson on Sun, 02/26/2023 - 20:08, In reply to Thanks Nat for this cogent by Clara Deser.

It has reduced the snow potential over the eastern United States. Question: Will you also be writing a paper about this? As always, we start with the ECMWF, the most often used and highly regarded seasonal forecasting system. Minnesota DNR. 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).
D.C.-area forecast: Nice today, a few showers early Thursday; Friday Among the winter outlooks issued by meteorologists so far, most agree that the southern United States will be drier and warmer than normal, with the best chance of colder and stormier-than-normal conditions in the northern tier, Midwest and Ohio Valley. We did have a high-amplitude MJO phase 3, which often leads to wet conditions on the West Coast.
AccuWeather 2022-2023 US winter forecast | AccuWeather With snow accumulation up to 88 inches, and entire summers with temperatures below freezing, the northern hemisphere was rattled with Satan's snow. This figure indicates that the Southwest December-January precipitation was below the 1991-2020 average in 13 of 21 La Nias during the period. Submitted by Nathaniel.Johnson on Thu, 03/02/2023 - 08:32, Tucson Intl Airport had 1.0 inches of snow today (March 2) bringing season total to 1.5 inches. Overall we still see less snowfall than normal for the first Winter month. Yes, Tucson is in the part of the Southwest where the La Nina dry signal is usually quite reliable. 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. So what exactly does this mean for the winter weather patterns and snowfall potential? As we emphasize on the blog, ENSO may tilt the odds toward one outcome or the other, but the forecast is always probabilistic. The displaced jet stream brings colder temperatures and winter storms from the polar regions down into the northern and northwestern United States. Due to arctic amplification (or not) the jet steam has been "wavy" this winter bringing colder than average temperatures to the SW (I live in Tucson) and unusual warmth to the east. It's an event unprecedented in our lifetimes.
A significant winter storm will plow through the East. But snow - CNN Most areas dry, breezy and very mild, though a few showers perhaps affecting southern England for a time. Although it's several months away yet, a typical La Nia winter in the U.S. brings cold and snow to the Northwest and unusually dry conditions to most of the southern tier of the U.S., according.
NOAA's 2022-2023 Winter Forecast | OpenSnow 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). 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 ) . Submitted by Nathaniel.Johnson on Fri, 02/24/2023 - 16:22, In reply to Other Teleconnections by Bob G. The biggest wild card in the weather for this year is the (massive) 5 to 10% greater global stratospheric water vapor content due to the injection of seawater from the Tonga volcano. Widespread extreme drought continues to persist across much of the West, the Great Basin, and the central-to-southern Great Plains. The greatest chance for warmer-than-average conditions are in western Alaska, and the Central Great Basin and Southwest extending through the Southern Plains. The video below shows the developing cold ocean anomalies in the equatorial Pacific as we head deeper into Fall, boosted by the strong easterly trade winds. Chris Bilbrey, a forecaster with the Colorado Avalanche Information Center, digs a pit with Rebecca Hodgetts, southern mountains lead . Understanding what teleconnection patterns we can and cannot predict on these seasonal time scales remains a big research topic. Maximum temperature 7C. This is an interesting question, and perhaps sometime Nat will have a chance to look into it. is favored for the Southwest, eastern areas of the Great Basin, as well as parts of the central and southern Rockies. This is mainly a result of warmer-than-normal temperatures expected in late Winter by UKMO in the south/southwest. The most dynamic winter weather is usually found between the warm and cold anomalies in the Midwest and the central United States. However, December may put the brakes on this, with a strong signal for this month to be much cooler than average. It was the largest snowfall of the season so far for Halifax and other communities of Nova Scotia. Their precip map show wetter that normal conditions for California during these types of events. Whether you are a fan of snow, here is the latest roundup of what meteorologists are saying about the weather in the coming months. We can also track snowfall potential on normal temperature and precipitation Winter forecasts. You can see that more snowfall is being forecast across much of the western United States compared to the previous forecast.

Comments must be on-topic; free of profanity, name-calling, or ad-hominem attacks; and cannot repeat misinformation about climate that has been widely debunked by authoritative sources. Temperatures overall will be below average but may gradually trend up later. More. How will the Hunga Tonga volcanic eruption play into the forecast? 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. Fast, informative and written just for locals. 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. December finally brings the cold. A cold morning with a fair amount of cloud around, though perhaps some brighter spells, where there could be early morning frost. So, that gets to the main point of the post. 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. More snowfall is also seen over parts of the upper Midwest. This way, we can use these anomalies as an indicator to better understand the current state of the global climate system and its seasonal development. With the La Nia climate pattern still in place, drought conditions may also expand to the Gulf Coast.. You can see a strong high-pressure system in the North Pacific and a low-pressure area over Canada and the northern United States. 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.. It's hard to say without looking at the study, but perhaps that was an analysis of observed La Nia events. This winter it seems the temps were fairly uniform across the equator. Submitted by Finn Stiles on Sat, 02/25/2023 - 05:01. Starting with the seasonal average, we see below-average snowfall over most of Europe, which is indicative of a high-pressure dominant pattern. 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. Oct. 13 2022, Published 3:08 p.m. The changes in the jet stream certainly have impacted conditions over the U.S. this winter.

Submitted by emily.becker on Thu, 02/23/2023 - 17:12, In reply to sampling differences by John N-G. That's a good question! NOAAs Precipitation Reconstruction over Land (PREC/L). Looking at the temperature analysis for the same winters, we can see a cold anomaly under the jet stream in western Canada and the northern United States. Winter has arrived, but what's the potential for cold and snow in the UK? This set consists of 30 simulations, and since there are 21 winter La Nia events between 1951-2020, I have 30 x 21 = 630 simulations of December-January La Nia conditionsa much larger sample size than if I just relied on the 21 observed La Nia winters. The brown bars indicate events with below-average precipitation, and the green bars indicate events with above-average precipitation. In winter, the land gets cold more quickly than the sea, so where there is a lot of land and very little sea, such as the huge interior of continental Europe, Canada or the United States, it gets cold enough for snow to fall frequently, it says. According to the Old Farmer's Almanac, winter will arrive early this year for the province, with frigid temperatures dropping down from the Yukon and northern Alberta by mid-to-late November. The December snowfall forecast shows the snowfall increase over the northwestern United States. What does the latest ocean analysis data show, and what influence did it play on temperature and snowfall patterns in the past? Below-normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes. 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. A somewhat subjective rating of the day's weather, on a scale of 0 to 10. Submitted by Scott Yuknis on Fri, 02/24/2023 - 04:55, In reply to About comments by rebecca.lindsey. More early Spring snowfall is also expected over the northwestern United States and the southern half of Canada while the La Nina influence slowly lets go. We will look at two highly regarded seasonal weather forecasting systems. And did tropical sea surface temperatures contribute? Weather.coms official winter outlook like NOAAs and AccuWeathers calls for above-normal temperatures in the South, while far-northern parts of the continental United States manage to stay below average, these conditions being driven by La Nia. During this period, the prevailing winds continue to blow from the northwest or northeast. Are you Weather-Ready for spring hazards? What is this gigantic hole that has appeared in the fields of Turkey? This is typically on the western and southern border of low-pressure systems, where the northerly and northwesterly flow pulls down cold air from the north. 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. Looking at the winter predictions for 2022-2023, there may be some weather you need to look out for. Get The 7 DMV newsletter in your inbox every weekday morning. How unusual were these Southwestern wet conditions in the first two-thirds of a La Nia winter? In the SPEAR simulations, I examined the relationship between the ensemble mean Southwest U.S. precipitation anomalies and the La Nina SST anomalies. We either require the cold air to meet a rain-bearing weather front and turn it into snow, or for the cold air to pick up enough moisture from its short journey across the North Sea, to form showers.. 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?
