Enjoy summer while you can, folks because Ontario's 2022 winter weather forecast is shaping up to be a real drag. This year La Nia returns for the third consecutive winter, driving warmer-than-average temperatures for the Southwest and along the Gulf Coast and eastern seaboard, according to NOAAs U.S. Winter Outlook released today by the Climate Prediction Center a division of the National Weather Service. Precipitation-wise, La Nina winters are usually drier over the southern United States. The Met Office's three-month outlook, for example, suggests this winter is half as likely as usual to be classified as wet. Thanks for your questions. The cold phase is called La Nina, and the warm phase is called El Nino. This will be followed by the Quadrantid Meteor Shower . Chris Bilbrey, a forecaster with the Colorado Avalanche Information Center, digs a pit with Rebecca Hodgetts, southern mountains lead . (Head to footnote 6 for all the gory math details.). which became the state's newest city in January 2022, . While AccuWeather forecasts that snowfall will be suppressed, the company does not necessarily expect overall precipitation to be below normal as well, with milder temperatures leading to several all-rain events this winter. These temperatures ranged from near-normal to 4F warmer than normal. 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. 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. Warmer and drier winter weather prevails over the southern states. Events were the coldest temps are in the central pacific and warmer temps in the east. 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. More. 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. But now, we will look at actual Winter snowfall predictions from the latest forecast models.

The notably small sea surface temperature differences between the wet and dry groups indicate that the sea surface temperature pattern plays a very minor role in the Southwest precipitation differences during La Nia, according to the climate model. 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. Submitted by Stan Rose on Wed, 03/01/2023 - 21:45. If skies are clear, temperatures can fall gradually day-by-day because the sun is weak and there is little cloud to keep in any heat at night. La Nina does change the weather globally, but apart from the direct influence over North America, places like Europe have many other factors in circulation before any La Nina influence can spread this far. Share. Long-range forecasters from a National Weather Service agency have issued their outlook for the 2022-2023 winter season. To determine this signal, I first calculated the average of the December-January Southwest U.S. precipitation across all 30 ensemble members for each La Nia. Below-normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes and the Alaska Panhandle. All good scientific studies note their limitations, and this analysis carries some caveats that are familiar to most climate scientists. 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. This is not too far from the ECMWF prediction, but we generally see more snowfall in the northern United States. As forecasted, the La Nina conditions will last over the Winter but will weaken. For entertainment purposes, we also summarize the outlooks from the Farmers Almanac and its rival, the Old Farmers almanac but meteorologists put little stock in those predictions. Remaining very mild. Secure .gov websites use HTTPS Such projections reflect typical conditions that develop during La Nia events, which are associated with an episodic cooling of ocean waters in the tropical Pacific. The bottom line is that La Nia may tilt the odds toward dry early winter conditions in the Southwest, but La Nia clearly does not eliminate the chance of wet conditions either. Let us know. 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.. The widely followed youtube weather channel, is calling for a mixed bag of weather this upcoming winter season. Minnesota DNR. So what exactly does this mean for the winter weather patterns and snowfall potential? 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. ET. 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. NOAAs Climate Prediction Center updates the three-month outlook each month. I like your work, but would encourage you to look up and not down for a cause of the weirdness (it's literally snowing in most of California today) that we are experiencing this year. Overall, the UKMO is much more dynamic than the ECMWF and leaves more possibilities open regarding pattern development. This model has been quite consistent with low snow accumulation since the early September runs. While December was above-average as far as the temperature goes, January was a different story. However, there is another way which requires very little wind at all high pressure that becomes established across the UK for a long time in winter. 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.. This will be the 3rd year in arow where the Irrigation systems in thisarea have Very little to NO Water Stored for the Irrigation Season. below-average surface temperatures in the central and eastern equatorial Pacific, signal relative to the noise of random weather variability, Stratospheric warming due to Tonga volcano, https://www.washington.edu/news/2022/10/03/study-suggests-la-nina-winte, Southeast Colorado and Northeast New Mexico. No cold event has gone into the 4th year in the known records, so it is expected that we will see the last La Nina phase this season for a while.

Quite unusual! This area is still feeling theeffects of the past 3 VERY Dry Winters. I find this type of study fascinating. This is mainly a result of warmer-than-normal temperatures expected in late Winter by UKMO in the south/southwest. Plenty of sunshine is expected across the south over the next few days, matching temperatures in St Tropez in southern France. But, with varying levels of success, they can paint a broad picture of how hot or cold or wet or dry different parts of the country may be compared to average.

It was the largest snowfall of the season so far for Halifax and other communities of Nova Scotia. Europe is not known to have any specific/direct influences, as it is too far from the source regions. The most dynamic winter weather is usually found between the warm and cold anomalies in the Midwest and the central United States. Such heavy precipitation was unexpected prior to the season in a region afflicted with a multi-year severe drought, especially given that we are in the third consecutive winter of La Nia. 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. 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. 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. The southern half of the country has a higher probability of warmer than normal weather. - 29 US states are under winter weather alerts as people brace for a winter storm expected to bring heavy snow .

You can see that more snowfall is being forecast across much of the western United States compared to the previous forecast. 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. Instead, the pattern looked a bit more like the positive phase of the Pacific Meridional Mode. Categories Long range / seasonal forecast. That's a good point!

The problem with this approach, however, is that our record of reliable observations is just too short to slice and dice the data in this way. That forecast extends to some popular California ski resorts. As that post notes, it's critical to understand the source of the mismatch models and observations (natural variability or model error or both? Thank you for your comment, and I agree that the influence of the stratosphere on seasonal predictability and predictions is an important topic that deserves continued focus. Areas depicted in white are regions where climate signals are weak and I realize that this winter has been more eventful in other parts of the country, notably in the western U.S., where torrential rains and heavy mountain snows occurred in December and January. The January snow depth forecast shows a similar pattern of more snowfall from western Canada into the northwestern United States. The standard deviation of this set of values is 0.725 mm/day. The February snowfall forecast shows snowfall potential remaining over the northern parts of the United States. We did have a high-amplitude MJO phase 3, which often leads to wet conditions on the West Coast. It has reduced the snow potential over the eastern United States.
