WEATHER BLOG: Cold Weather Coming

We are looking at a much cooler start to the day today with radiational cooling overnight. Morning temperatures will be at or below normal before the sunshine comes up. The high pressure system influencing the area is currently to our north near Nova Scotia and is being impinged upon by low pressure moving out of the Great Lakes. This low should stay off to our west through the day today but winds will turn out of the southeast and let us get up to normal. Overall it shouldn't be a terrible start to the weekend.

The low off to our west is bringing a good thump of snow across Iowa, Wisconsin, and far northern Illinois. Luckily that low rapidly swings northward into the upper trough and it looks as though we will avert much in the way of wet weather Saturday night into Sunday. At the same time as this low pulls off to our north, a large amount of moisture is sitting along a stalled boundary off the Atlantic Coast. As we move into Monday and Tuesday, the upper trough will continue east and bring much colder air over our region, while keeping an immense amount of rainfall off the coast. If chilly
temperatures are the worst we see Sunday afternoon through Tuesday we will have lucked out considering having the two big weather makers so close.

High pressure moves overhead and out of the southeast on Tuesday and the trough leaves the region to the northeast. The result will be some nice weather for Wednesday traveling and Thanksgiving Day. In fact, Thursday may be one of the nicest days you can ask for given the time of year. Some sunshine mixing through the clouds and above normal temperatures are expected. The mornings midweek will be chilly though, thanks to radiational cooling at night. High pressure will work hard for us on Friday to keep us dry and warm again, before what could be a wet day on Saturday.
