Boundary comes through early up here, it’s a tomorrow afternoon/evening heat and muggy night before early AM FROPA.
This summer so far is characterized by brief single afternoons of heat, then days of 70s over 50s.
As of 348 AM EDT Thursday...From Monday night through mid-week there remains a large spread in guidance in the evolution and strength of an upper ridge over the central CONUS and any shortwave energy that roles over into the Northeast. There`s little to hang your hat on leaning towards any one solution so have continued to highlight low chances for showers at this time. In general, the Northeast does look to remain under cyclonic flow though, favoring slightly below normal temperatures.
