DISCUSSION

KEY MESSAGE 1...Rain with isolated thunderstorms today. A chance of showers with a slight chance of thunderstorms Saturday.

KEY MESSAGE 1 DESCRIPTION... Surface low pressure, along with the supporting upper trof, will cross the region today. Rain will occur across the region today. Isolated thunderstorms are also possible this afternoon. The surface system will exit across the Maritimes tonight, though upper level troffing will persist. Rain will taper to showers early tonight before ending overnight. Upper level troffing will persist across the region Saturday. With diurnal heating, expect another chance of showers Saturday. Could also have the slight chance of an afternoon thunderstorm.

KEY MESSAGE 2...Unsettled weather and a gradual warming trend from Saturday into the middle of next week, with chances of afternoon showers and thunderstorms nearly every day.

KEY MESSAGE 2 DESCRIPTION... A fairly wet weather pattern persists from Saturday into the middle of next week. While we probably won't see any well defined weather systems, persistent NW flow aloft around the east side of an upper level ridge, coupled with a fairly moist airmass, will allow for a chance of afternoon showers and storms pretty much every day Saturday to Wednesday. This will be the type of situation where we are unlikely to get any all-day rains, but there's a decent chance of a brief interruption in outdoor activities any day in the afternoon hours. While we can't rule out a few severe storms, most of the storms in this sort of pattern will be more run-of-the-mill. If any day were to see a break in the afternoon showers/storms, it would be Monday, but most other days, the chance looks to be 30-60 percent that any spot would see measurable rain at some point during the day any day.

Temperatures this weekend will be close to average with highs in the 70s, and potentially some low 80s Downeast Sunday, but then we warm a bit from Monday to Wednesday. There is some uncertainty just how warm we get, but at least low to mid 80s seems like a fairly safe bet, with nighttime lows becoming mild with upper 50s to mid 60s. It will be a bit muggy too, making it feel rather uncomfortable.
