Upper Levels: An intensifying upper level trough moves into the area tomorrow before shifting to eastward on Friday but Troughing will persist near the northeastern states into the middle of next week.
Surface: A warm front will pass through the region today ahead of a developing low pressure system in the midwest. As that low intensifies and tracks to our north, it will eventually drag a cold front across the region Thursday night with a round of showers and isolated thunder. In its wake high pressure will build in through early next week. Temperatures will drop sharply Thursday night and Friday as the pressure gradient tightens between the departing storm system building high. A dry cold front boundary will make an approach Saturday evening and an offshore low will develop on Sunday enhancing winds across eastern zones once again and helping to draw in some reinforcing cold air.
Discussion: Turning mild today with partial sunshine and temperatures nearing 70 degrees. The mild weather will last until a cold front makes an approach tomorrow evening featuring a gusty round of showers and isolated thunder. Remaining windy into Friday as a much colder airmass moves into the region with sunshine chilly weather to last into next week.
