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 tonight while an occluded front approaches from the west. An area of rain will begin to expand eastward across the forecast area tonight 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. The developing low will cross the Gulf of Maine Thursday night. Rain chances will begin to diminish later Thursday night. The surface low exits across the Maritimes Friday, with a trof extending back across the forecast area, while the upper low begins to move south across the region. Showers will persist across the region Friday, with the better chances across northern areas. Could also have the slight chance of a thunderstorm Friday afternoon. The surface/upper lows vertically stack across the Maritimes Friday night into Saturday, slowing the movement of the system. A disturbance moving around the Maritimes system will rotate across the region Saturday. 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. Generally expect rainfall totals of a half to three quarters of an inch across much of the forecast area Wednesday night into Saturday, with areas of up to around an inch.
