Rain is in the forecast across the Commonwealth. A low pressure that has been stalling just to the north will finally begin to move further east today, turning winds Northwest off of the lake. Clouds and rain will be expected throughout the state as a result, with temperatures staying cool as well. Conditions look to improve for Wednesday and Thursday when a strong high pressure moves into the region, bringing sunny skies and warmer temperatures. By Thursday evening, another low pressure will begin to strengthen in the Great Lakes region of the country and will slowly begin to push eastward. Overnight Thursday will see the passage of a warm front associated with this system, bringing rain and even a chance at some thunderstorms. This chance should continue throughout the day Friday with hot and humid conditions. As the weekend starts, a weak cold front is expected to cross the state, and Saturday will see rain and a few thunderstorms once again.
