Thanksgiving is often noted as the busiest travel day of the year. Whether you plan to travel near or far, in a plane or in a car the KDLT Weatherblog highlights this years Thanksgiving travel forecast.
Quiet weather persists over much of the country this week, as a large ridge of high pressure will bring sunshine and much warmer temperatures to the region. Temperatures have been above average all week and will continue to warm Wednesday. Temperatures will warm between 20 and 30 degrees above average with many areas coming very close to breaking afternoon high temperature records.Afternoon high's Wednesday will warm into the 60's and 70's while average afternoon high's are usually in the 30's and 40's.
(Wednesday's Record's to beat and Forecast High Temperatures)
Travel weather for Wednesday will be very pleasant with abundant sunshine, a light breeze and warm temperatures. Areas of Montana could see a light rain/snow mix with cooling temperatures however much of the region will see quiet and calm weather for the day before Thanksgiving. None of the regions airports are expecting weather-related delays.
(Regional Travelcast for Wednesday)
An area of low pressure will move across North Dakota and Minnesota for Thanksgiving day bringing areas of rain showers and light snow flurries to the extreme northern United States. The low pressure center will drag a cold front across our area Thursday morning, which will increase winds across the region. Expect winds gusting in excess of 30 miles per hour towards the afternoon and early evening. Skies will remain mostly clear and temperatures mild with afternoon high temperatures into the 50's. The cool air behind the cold front will take some time filtering in until late Thursday.The rest of the country will remain sunny and warm with slightly cooler temperatures expected in New England.
Temperatures will remain above average Thanksgiving Day as cooler air behind the cold front will hold off until Friday.
The warm weather will not last long as the cold front Thursday will usher in some much cooler temperatures by Friday morning. Cold Canadian air will be ushered in by northerly winds essentially dropping our temperatures by more than 30 degrees in 24-hours.
(GFS Model valid for Friday Morning)
The cool air will move on towards the east for Saturday and Sunday as temperatures will warm slightly ahead of our next cold front. This next cold front forecasted to move in by Monday morning might be the coldest air we have seen so far this season. Cold Arctic air will likely become displaced from the arctic and surge south with a strengthening low pressure. While we will likely see temperatures well below average, the low will pass to our east, which will take any chances for snow well away from our area.
While the majority of November has been well above average some of our long-range models hint at a very cold end to November. At this point, things will likely change as it is still far out but the chances still remain very good for some very chilly weather moving in.
