In a wet summer, it's been fairly dry lately. A few showers/storms Tue/Wed then....
Thursday and Friday...
Post-frontal airmass with high pres building in from the Gt Lakes
will bring dry conditions with seasonable temps. High pres and NW
flow aloft will keep Idalia and its moisture well south of New Eng.
Pleasant days with highs in the 70s with chilly nights. The coolest
night will be Thu night with lows dropping into the upper 40s
in the typically colder locations by Friday morning.
Saturday through Monday...
Continued dry weather but a warming trend is expected as high pres
shifts offshore and mid levels gradually warm. GEFS and EPS
ensembles indicate high probs of highs 80+ Sunday and Monday, while
GEFS has 30-50 percent probs of 90 for Monday. But this will depend
on sub-tropical ridge axis building east into New Eng. There is
uncertainty with how quickly an amplifying trough exits east of New
Eng next Mon which will impact temp forecast.
