DISCUSSION

KEY MESSAGE 1...Widespread soaking rain expected Thursday. Some drought relief is possible, though flooding is not expected.

KEY MESSAGE 1 DESCRIPTION... High pressure exits across the Maritimes Wednesday night while an occluded front approaches from the west. An area of rain will begin to expand eastward across the forecast area Wednesday night in advance of the front. A disturbance moving around an upper low across Quebec province will help support a developing low along the front Thursday. Rain will occur regionwide Thursday, along with the slight chance of an afternoon thunderstorm. The developing low will begin to cross the Gulf of Maine Thursday night, though the exact track is still uncertain. Rain chances will begin to diminish later Thursday night. The surface low exits across the Maritimes Friday, while the upper low crosses the region. Showers will persist across the region Friday, with the better chances across northern areas. The surface/upper lows vertically stack across the Maritimes Friday night into Saturday, slowing the movement of the system. Shower chances will persist Friday night into Saturday. The system then exits Saturday night into Sunday. The entire forecast area should receive a soaking rain Later Wednesday night into Thursday night. However, rain totals are still uncertain dependent on exactly where the surface low develops and how rapidly the system exits.
