As the Thanksgiving travel period kicks off this weekend and continues through the following weekend, at least three storms of note have the potential to cause trouble on the roads and at the airports across the United States.
More than 55 million travelers have plans to venture at least 50 miles away from home from the Friday before Thanksgiving to the Sunday after Thanksgiving, according to the American Automobile Association (AAA). The holiday travel volume is expected to be second-highest behind 2005 since tracking began in 2000, AAA said.
An active storm track is forecast to bring a wintry mix this weekend to the Midwest and Northeast, prior to a more significant and potentially very disruptive storm for the central U.S. during the peak of the Thanksgiving travel time.
The same storm forecast to bring much-needed rainfall to part of California and the Southwest states at midweek and soaking rain to the South Central states late this week is expected to turn toward the Midwest and East this weekend.
Rain and a couple of thunderstorms are likely to extend from the lower Mississippi Valley to the Ohio Valley from Friday to Saturday then from the southern Atlantic coast to the mid-Atlantic and southern New England from Saturday to Sunday.
While the rain can make for slick travel on the roads, poor visibility due to patchy fog and a low cloud ceiling can lead to airline delays at some of the major hubs from Atlanta to Cincinnati, Pittsburgh, Washington, D.C., Philadelphia and eventually New York City and Boston.
On the storm’s colder northwest flank, a wintry mix and some snow could extend from parts of the central Plains Friday night to the middle Mississippi and Ohio valleys Saturday and the Great Lakes and Northeast region during Saturday night.
The hubs of Cincinnati, Cleveland and Pittsburgh may be affected by some wintry precipitation for a time this weekend. Should the storm push farther north into the cold air, the wintry precipitation zone could reach Detroit and Chicago.
The next cross-country storm, which will originate over the Gulf of Alaska this weekend, is forecast to dip over the Northwest and northern Rockies early next week.
While this new storm will bring rain showers to the Seattle and Portland areas, snow will spread over the northern Rockies, the mountains of the interior Northwest and the northern Plains from late Sunday to Monday.
Snowfall is likely to occur at to pass elevation levels with this storm, so motorists should anticipate delays as the storm moves in.
In terms of Thanksgiving travel, in lieu of any bad weather, there’s “nothing worse than Wednesday,” the AAA said in its statement. Trips made on the Wednesday before Thanksgiving can be four times longer as commuters mix with holiday travelers, according to AAA.
Bad weather can greatly magnify the travel delays.
That same Northwest storm is likely to regroup over the central and southern Rockies from Tuesday to Wednesday.
There is the potential for heavy snow and winterlike travel conditions with substantial delays for a 1,200-mile stretch of the heartland. Wintry weather could spread from eastern Colorado and northeastern New Mexico to parts of Wisconsin, Minnesota, and Michigan as Thanksgiving travel surges next Wednesday.
There is the potential for heavy snow and winterlike travel conditions with substantial delays to spread from eastern Colorado and northeastern New Mexico to parts of Wisconsin, Minnesota, and Michigan as Thanksgiving travel surges.
Should the storm develop to its maximum intensity, blizzard conditions may unfold over part of the Upper Midwest with strong winds and low visibility.
Chicago could be in middle of the worst of the storm’s wintry side or it may just avoid it. Either way, ripple-effect airline delays may increase as the large and strong storm unfold over the region as many flights connect to or originate from O’Hare International Airport.
“There is a chance the storm turns far enough to the east to allow some snow and/or a freeze-up in parts of Indiana, Ohio and western Pennsylvania late Wednesday and Wednesday night,” according to AccuWeather Meteorologist Max Gawryla.
The same storm is likely to produce locally heavy rain and thunderstorms on its warm side over the southern Plains and the lower Mississippi and Tennessee valleys by the middle of next week.
“Depending on how quickly this story system strengthens, we could be contending with severe thunderstorms from Arkansas and Louisiana through southern Indiana and western portions of Kentucky and Tennessee,” according to AccuWeather Senior Meteorologist Randy Atkins.
Should the major storm next week move faster, heavy rain, gusty winds and poor visibility could hit travel hard in the Southeast and the Northeast during the day and night before Thanksgiving.
Meanwhile, an intense storm is likely to track more slowly and potentially farther west over the Central states. Such a storm may delay the arrival of rain and colder air on the Atlantic coast and might allow severe thunderstorms to push farther north with warm air into the Ohio Valley and potentially the Great Lakes region.
So, not only may there be normal heavy holiday traffic on the roads and at the airports, a storm may really throw a wrench into plans during the day and night before Thanksgiving over the Central and Eastern states.
Another storm is likely to move in from the Pacific Ocean and could have negative impact on travel with low-elevation coastal rain and mountain and inland snow in the Northwest from Wednesday to Thanksgiving Day.
This far out, the track, strength and timing of each storm can change. STAY TUNED TO OUR LIVE SHOWS ON YOUTUBE!
The Frost and Freeze map shows where frost cant be expected and where temperature are forecast to fall below 32 degrees F. Frost is a solid deposition of water vapor from saturated air. It is formed when solid surfaces are cooled to below the dew point of the adjacent air. Frost crystals’ size differ depending on time and water vapor available. Frost is also usually translucent in appearance. There are many types of frost, such as radiation and window frost. Frost causes economic damage when it destroys plants or hanging fruits. It can also damage road surfaces through a process known as frost heaving.
If a solid surface is chilled below the dew point of the surrounding air and the surface itself is colder than freezing, frost will form on the surface. Frost consists of spicules of ice which grow out from the solid surface. The size of the crystals depends on time, temperature, and the amount of water vapor available.
In general, for frost to form the deposition surface must be colder than the surrounding air. For instance frost may be observed around cracks in cold wooden sidewalks when moist air escapes from the ground below. Other objects on which frost tends to form are those with low specific heat or high thermal emissivity, such as blackened metals; hence the accumulation of frost on the heads of rusty nails. The apparently erratic occurrence of frost in adjacent localities is due partly to differences of elevation, the lower areas becoming colder on calm nights. It is also affected by differences in absorptivity and specific heat of the ground which in the absence of wind greatly influences the temperature attained by the superincumbent air.
Because cold air is more dense than warm air, in calm weather cold air pools at ground level. This is known as surface temperature inversion. It explains why frost is more common and extensive in low-lying areas. Areas where frost forms due to cold air trapped against the ground or against a solid barrier such as a wall are known as frost pockets.
Map: November 2019 Snowpack | Who Has Snow?
Jake didn’t add this in our latest video but I felt it was worth a mention!
The 2019-2020 ski season is off and running with ski resorts from Vermont to Tahoe spinning chairlifts and serving up ski runs. It’s still very early in the ski season, but the daily SNOTEL map gives us an idea of who are the early season snowfall leaders and laggards.
So who is having the best early season? Look to Montana where snowpacks are at near 300% of normal.
Ski areas in California and Oregon are unfortunately off to slow starts. But don’t get to down just yet. It’s only mid-November with months of cold and snowy weather ahead.
The areas of the map that are purple, blue and green are snowpacks that are above average. Measurements are taken automatically at backcountry weather stations called SNOTEL. (scroll down for UK weather)

Snow weather warning: Blizzards forecast for White Christmas as temperatures plummet
SNOW is expected to hit the nation as a cold spell could bring temperatures down to -10C, sparking hope of a White Christmas this year.
Temperatures in the UK could dip to -10 this week, forecasters have warned. The freezing spell has prompted hope of snow this Christmas as long-range forecasts indicate a risk of heavier and more widespread snowfall for the final part of November and into next month
Exacta Weather’s James Madden said: “There is the risk of more cold weather and snow of a more potent and widespread nature during the second half of this month and into December.
“Wintery conditions are likely to feature and be more prominent across higher ground next week, some sleet and snow is not out of the question to some lower levels.
“This will be most likely in parts of Wales, the Midlands, and even as far south as south-west England at times.
“Current indications suggest a possible white Christmas in some parts to the north and west of the country, and the likes of Aberdeen or Manchester could see snow.”
NH Snow cover extent to wk44, highest since 1999
