DISCUSSION

KEY MESSAGE 1... Unseasonably cool temperature will continue through the weekend.

KEY MESSAGE 1 DESCRIPTION... Below normal temperatures will persist across the region on Friday with continued northerly flow and cloud cover expected. Afternoon highs on Friday will be about 10 degrees below the normals for this time of year. Upper level low pressure will be diving southward from Quebec Province during Friday. Latest guidance keeps this system far enough to our west through Friday night that impacts across our forecast area should be minimal. However, our western areas will be on the eastern periphery of the shower activity associated with this system. Thus, portions of the north Maine Woods and central Maine Highlands may see a few showers from late Friday afternoon through Friday evening. Rainfall amounts will be light, generally a tenth of an inch or less. Across the far north, it is expected to remain dry. There is the potential for patchy to areas of frost across northern areas Friday night.

For Saturday, the closed low pressure system will move over the waters. Cool NE flow along with 925mb model temps around 0C will keep daytime surface temps well below normal. Expect temps in the mid to upper 50s. By Saturday night, clouds are expected to clear and winds should calm and switch to a NW flow. Temps should reach into the mid to upper 30s with areas of frost possible in the north. Highs on Sunday still remaining below normal. A prolonged period of below normal temps through the day on Tuesday before temps begin to moderate by mid-week.
