Key Messages
1. Dry weather continues areawide through the weekend and into next week. A cool and dry airmass will bring widespread overnight lows in the 20s tonight and Saturday night.
Discussion
KEY MESSAGE 1 DESCRIPTION...
High pressure remains centered across Quebec through Friday, before gradually shifting south of New England through the weekend. At the same time, Josephine moves away while remaining well offshore through the day tomorrow, with the pressure gradient between the two bringing one more day of breezy conditions.
As the high crests overhead Friday night, the dry airmass allows for a cold night with lows falling into the 20s for most of the area, and some teens across the north. The high continues to move southward, setting up a moderating southwest flow by the end of the weekend. Temps rebound back into the 60s for Sunday and Monday.
A weak front passes through on Monday with little more than a few sprinkles across the north. Behind the front, a new high pressure center arrives with a cooler airmass. Highs return to the 40s and 50s for Tuesday and Wednesday, before beginning to rebound back into the 60s for the end of the week as the high moves offshore.
At this time there is still no meaningful rainfall in the forecast for at least the next week.
Aviation
Through 06z Saturday: Occasional N gusts around 20 kts ease this morning. Otherwise, VFR is expected today through tonight. Calm winds and clear skies tonight could promote BR/FG development for valley locations (particularly HIE/LEB), but the dry airmass may also help deter this.
Outlook...
Saturday-Wednesday...VFR prevails under high pressure. This should lead to light diurnal wind patterns.
