Rain is in the forecast across the Commonwealth for the short term, as a low pressure system that has been stalling just to the north will finally begin to move further east today, turning winds northwesterly, off of Lake Erie. 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 sunnier skies and warmer temperatures. By Thursday evening, another low pressure system will begin to strengthen in the Great Lakes region 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.
