High pressure overhead and low pressure off the mid-Atlantic coast will keep us in a cool northeasterly flow over the next several days. The low to our south will slowly drift north as it meanders toward the Virginia Capes by Friday morning. Moisture from this system wants to spread into western Massachusetts by Thursday night and Friday while high pressure just to our north will try and suppress the system from doing so. It is a tricky outlook and we will be right on the fringe of the precipitation shield, especially Thursday night and Friday.
As we get into the weekend we are hopeful the high wins out and pushes the clouds and rainfall southward, maintaining a mostly dry weekend, but it will be a close call. Skies will likely vary from partly to mostly cloudy through the weekend while the storm actually begins to drift south and weakens. The further south it moves the better the weather through the weekend.
Temperatures do remain on the cool side through the next five days with daytime high generally in the 60s and overnight lows in the 40s. Winds are expected to persist out of the east and northeast at 10 mph or less.
