Discussion

Strong and sprawling high pressure over the northeastern quadrant of the nation will continue to be the main player around here during the next several days and a key to the season’s first extended unseasonably warm stretch of weather. There will be a back door cool front that pushes from east-to-west across the region later today and low-level easterly winds will develop and likely knock off at least a few degrees in the temperature department compared to Wednesday’s highs and overnight lows should be in the 50’s. A stronger and more conventional cool front is likely to drop southeast from the Great Lakes region at the end of the weekend and its passage should usher in somewhat cooler air for the early part of next week following a very warm weekend.
