DISCUSSION

KEY MESSAGE 1... Unseasonably cool through Friday then moderating temperatures into early Thursday evening, but any significant storm systems stay well south of the region.

KEY MESSAGE 1 DESCRIPTION... A closed 500 mb low passes to the north then northeast tonight, then slowly drifts south through the western Maritime Provinces through Thursday night. The result will be unsettled weather into Thursday evening, before the axis of the low passes to the south. At the surface, this will result in one weak area of low pressure passing well to the south tonight, and a second one crosses Maine on Thursday. Precipitation should be mainly in the form of rain showers tonight, then mixes with or changes to rain across mainly the North Woods Thursday before tapering off Thursday evening. Highs on Thursday should run around 10 degrees below normal.

By Friday, temps are expected to remain in the 40s due to persistent upper level low over the Canadian Maritimes. By Saturday, the next upper level low over the northern Great Plains will push the Canadian low to the east. This will allow for clearer skies and warmer temps. Significant storm systems will remain south of the region through the weekend though some operational runs indicating fairly compact s/wv moving into the area Sunday night into Monday morning. This would likely be enough to keep the temperatures below normal early next week.

AVIATION /18Z WEDNESDAY THROUGH MONDAY/

Likely becoming MVFR this evening throughout, with a chance of becoming IFR late tonight/Thursday morning. Conditions should improve to MVFR at most terminals early Thursday afternoon. Winds become light and variable throughout this afternoon and remain so into Thursday morning. Winds then become NW-N at 10kt or less early Thursday afternoon.

Thursday afternoon/night: Becoming VFR throughout by early Thursday evening. NW-N winds G15-20KT possible Thursday afternoon and evening.

Friday-Saturday night: VFR. NNW 5-15kts.

Sunday-Monday: VFR. Light winds.

MARINE

Winds should remain just below SCA levels this evening on the coastal ocean waters with a few gusts to 25 kt possible. Otherwise winds should be below SCA conditions on the coastal ocean and intra-coastal waters and below gale levels on the ocean waters tonight-Thursday night.

High pressure will keep winds and seas below small craft levels from Friday into early next week.
