DISCUSSION
KEY MESSAGE 1...Patchy/areas of frost possible across northern areas tonight.
KEY MESSAGE 1 DESCRIPTION... High pressure will build across the region tonight, bringing clear skies and light winds. This will result in favorable conditions for radiational cooling. Low temperatures will generally range from the mid to upper 30s across much of northern Maine. However, temperatures could locally drop to around freezing across northwest areas. Patchy/areas of frost are possible tonight across northern areas, particularly in the normally colder low lying locations. Patchy river valley fog is also possible later tonight.
KEY MESSAGE 2...Chance for rain showers by late next week, though little to no drought improvement anticipated.
KEY MESSAGE 2 DESCRIPTION... Low pressure system to the far north moves eastward, pushing a front through New England late next week. Ensemble models have slowed the progression of the front with more members leans towards Thursday evening and Thursday night for rain. Upper air model soundings indicate a large dry airmass ahead of the front. This coupled with the decreasing intensity of the front, rain showers look to be minimal, especially for the north. Cannot rule out some scattered rain showers across the south.
