What Has Changed
No significant changes to the going forecast this early Wednesday morning other to add more wind information for later Thursday into Friday.
Key Messages
1. High pressure remains in control of the weather pattern across northern New England through the weekend while an ocean storm passes offshore. Northerly gusts of 30 to 35 MPH possible later Thursday into Friday.
Discussion
KEY MESSAGE 1 DESCRIPTION...
High pressure keeps northern New England dry through the end of the week and the weekend, while an offshore ocean storm brings some cloud cover into parts of the region this week.
An inversion around 925mb moves in aloft during the daytime today, keeping temps a bit cooler today. Additionally, high cloud cover spreads inland from the coastline as cirrus from the offshore storm moves northward.
Temps rise a few more degrees ahead of a weak front on Thursday, before falling back again on Friday. The ocean storm makes its closest pass Wednesday night and Thursday, before tracking near the Canadian Maritimes.
The pressure gradient between the offshore storm and high pressure building in from the northwest could cause gusty winds later Thursday into Friday morning. Current forecast soundings indicate that northerly gusts could top 30 to 35 MPH.
The broad high pressure center then drifts southward from the end of the week through the weekend. Centered south of New England, the high brings a moderating trend through the weekend and early next week, along with continued dry conditions. Highs return to the 60s by Sunday, with some low 70s possible by Monday next week. A weak cold front is possible by Tuesday next week, but at this point it looks mostly dry as well.
