DISCUSSION
KEY MESSAGE 1...Gusty winds from the northwest during the day Friday could lead to isolated power outages.
KEY MESSAGE 1 DESCRIPTION... Cooler air moving in, with a strong pressure gradient, will lead to gusty winds over land during the day Friday. Anticipating max gusts 30-40 mph, with the greatest threat across Northern Maine and into the Bangor region. This will be strong enough to lead to isolated power outages. The primary threat is during the day Friday from mid-morning to sunset.
KEY MESSAGE 2...Potential for frost Saturday night across the north.
KEY MESSAGE 2 DESCRIPTION... High pressure will be building in Saturday evening from Canada. Movement of the high will determine how low temps can drop Saturday night into Sunday morning. Operational guidance and ensemble members indicate that sfc high should be cresting over CWA around 06z Sunday with return flow kicking in after this time. Winds should decouple and with uncertainty in thickness of cloud cover spilling into the area overnight have gone on the colder side of guidance with river valleys dropping to near to just below freezing, mainly over nrn areas. Have included patchy frost in forecast for Saturday night.
