DISCUSSION

KEY MESSAGE 1...

KEY MESSAGE 1 DESCRIPTION... Dry airmass will continue to move into the region on northerly flow on Friday. 1035mb sfc high pressure will be building south out of Canada and depending on how quickly it crests over the state will determine how low temps can fall. Current thinking is that while airmass will be very slowly moderating from Friday morning continued frost threat remains for Saturday morning. With high pressure axis just to the west of CWA late Thursday night and again Friday night, lower valleys should decouple bringing ideal radiational cooling to the area late. This should result in areas of frost Thursday night and widespread frost Friday night over northern Aroostook, northern Piscataquis and northern Somerset counties. This will bring damage to any outdoor plants and vegetation over these areas. Frost looks likely to the north and east of the Central Highlands.
