Key Messages
1. Breezy winds abate Friday afternoon followed by high pressure dominating the weather pattern through much of next week.
Discussion
KEY MESSAGE 1 DESCRIPTION...
A gradient between high pressure over Quebec and Josephine well offshore will persist over the forecast area through Friday morning. Breezy northerly winds continue this evening and will subside some tonight while remaining elevated. Breezy northerly winds combined with cool air will bring sub freezing wind chills to much of the area Friday morning. Winds will start to relax Friday evening as high pressure builds close to overhead. High pressure will center over the area Friday night through Sunday bringing optimal conditions for radiational cooling. This will allow for lows to drop below freezing across the area both Friday and Saturday night. Day time highs will moderate into the 50s Saturday and 60s on Sunday.
High pressure slips south Monday as a dry cold front approaches from the NW. It will be mild Monday ahead of the cold front with highs in the mid to upper 60s south of the mountains. The cold front crosses late Monday with high pressure returning through the balance of next week. This will allow for chilly nights with lows in 20s and sunny but cool days with highs in the 40s and 50s.
Aviation
Through Friday: Gusty N winds to 20 kts will continue through tonight, although may be intermittent. A 40 kt NE LLJ around 2000 ft along the coastal plain could lead to LLWS if surface winds do not remain elevated. Otherwise VFR is expected tonight through Friday.
Outlook...
Saturday-Tuesday...VFR prevails under high pressure. This should lead to light diurnal wind patterns.
