Long range forecast for november
Huntsville , Alabama, measured 5. These atmospheric ingredients will also be present to generate some early-season snow, but this will not be an indicator of how the entire winter will play out, but instead , the start of a bookend winter in terms of snowfall. An overturned tree sits in front of a tornado-damaged home in Mayfield, Ky. Hazards of a different and more traditionally winter variety could also develop this season.
This winter is indeed looking like a snowy one across most of the northern tier of the contiguous United States, but AccuWeather senior meteorologist Paul Pastelok says , there is more to the forecast than just snowstorms. Last year, there were several snow events across the region that blanketed some southern cities.
The clash of cold air with lingering warmth could spark an out-of-season severe weather event in the Midwest or Ohio Valley late in November or in December. Severe weather as a whole decreases across the U. In , a tornado outbreak across Louisiana, Mississippi and Alabama on Christmas Day spun up 34 twisters and 84 damaging wind reports and cut power to families as they tried to celebrate the holiday with their friends and families.
The snowfall totals will be boosted by a few nor'easters, with January and March bringing the highest chances of powerful coastal snowstorms. AccuWeather 's approach to concocting the winter forecast, one of its most highly-anticipated seasonal outlooks, is a bit different: The process involves a team of veteran long-range forecasters analyzing computer models, looking at how previous winters have played out and using their own personal experience to determine if it's going to be a snowy winter, if and when the polar vortex will unleash Arctic air across North America and whether it will be a good season for skiers.
Pastelok added that if the water in the Gulf of Mexico and along the Atlantic coast remain warmer than usual, there is the chance for a "potentially big system" to develop during the second half of the winter that could impact the East Coast. One of the more unusual factors that could influence the overall weather patterns this winter can be traced back to a cataclysmic volcano eruption that took place in the early weeks of The volcano spewed an unprecedented amount of debris high into Earth's atmosphere which, as Pastelok will explain, could still be having an effect on the weather on a global scale.
This is lower than last winter when there were four occasions on which snow accumulated across the region. Snowfall for the season as a whole is likely to be below normal for most of the central Appalachians, Ohio Valley and interior mid-Atlantic, but precipitation could end up above normal with a few all-rain events likely to unfold throughout the winter.
A wave of chilly air swept across the Northeast and Midwest just in time for the arrival of astronomical autumn, which started on Sept. Residents across the Northeast and Midwest will experience a few winter previews in November and December as waves of cold air dive down from Canada, but the biggest blasts of cold air will hold off until later in the winter. Farther west, near- to above-normal lake-effect snow is expected.
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.

The best opportunity for snow or wintry precipitation across the interior Southeast will arrive in January and early February with one or two snowfall events possible in this timeframe. AccuWeather long-range forecasters are predicting that 40 to 50 inches will accumulate in the city, around the average snowfall amount of Last winter, Boston finished the season with 54 inches of snow with In cities such as Washington, D.
Last January, accumulating snow was observed on just four days throughout the month, amounting to This winter, AccuWeather is predicting that Washington, D. Even when it does snow during the week, the impacts on daily routines may not be the same as they were a few years ago. Outside of that region, New England is one of the only areas east of the Rocky Mountains where snowfall could end up being above normal.
With this in mind, AccuWeather is ready to make its annual prognostication and unveil a detailed region-by-region breakdown of the U. A mild winter is in the forecast for most of the southeastern U. Instead, it's the water temperature in the Gulf of Mexico and along the Atlantic Seaboard that has meteorologists' attention. The weather setup will be one of the most complicated and dynamic in recent memory due to all of the weather factors in play over the upcoming months, Pastelok said.

Despite what will be the third La Niña winter in a row, this winter will not necessarily be a carbon copy of the past two. Boston may end up being the only major city along the Interstate 95 corridor that finishes the winter with near-normal snowfall. Temperatures this low can also cause the cold-blooded iguanas that reside in Florida to become temporarily stunned by the cold to the point that they appear dead before the warmth reanimates the reptiles.
In addition to fueling an active final stretch of the Atlantic hurricane season, which officially lasts through Nov. Some heavier rain events will be possible across the Gulf Coast states and into the Tennessee Valley from December into February, including the risk for some severe weather, Pastelok said. Pastelok and his team of long-range forecasters are predicting a "triple dip La Niña ," as it is the third winter in a row that La Niña will shape the weather patterns across the U.
The regular climate phenomenon occurs when the water near the equator in the eastern Pacific Ocean is cooler than average, which in turn influences the jet stream and the overall weather patterns in North America. In recent winters, there have been cold spells in Florida that sent the mercury dipping down into the 30s and 40s F, enough to cause frost and freeze in the typically warm state, which can endanger some of the state's temperature-sensitive citrus crops.
Winter is fast approaching, but AccuWeather meteorologists say that it will shape up much differently than last winter in part due to a volcano that erupted on the other side of the globe. As for Floridians and reptilian inhabitants of the Sunshine State, the pushes of frigid air that do make it to the Southeast might come short of intruding deep into central or southern Florida.
Pastelok said that the chance of a widespread frost or freeze is low this year, but if it does occur, it will likely take place in late January. By Brian Lada , AccuWeather meteorologist and staff writer.
