Comfortable weather to start this week, then back to the hot and humid conditions

Forecast

Less humid and breezy by Sunday...

TONIGHT: Mostly Clear, Comfortable. Diminishing Winds. Lo 62. Winds: W 5-10 mph.

MONDAY: Mostly Sunny, Pleasant. Hi 84.

TUESDAY: Hot, Humid, Stray PM Storm. Hi 90.

Clear skies will continue to dominate tonight with tranquil conditions. Temperatures will drop to the low 60s and upper 50s in outlying areas (this after we officially hit 88° for a high)! This is the impact the cooler and drier air will have. The breezy will also calm down through tonight and tomorrow morning.

Tomorrow brings more user-friendly weather for this time of the year with highs in the mid-80s and manageable humidity. We also stay rain/thunderstorm free during the day.

By the middle part of this week, a returning classic summer time pattern sets up over Pennsylvania and really much of the eastern United States. Temperatures are likely to hit and/or exceed 90 several days, with humidity becoming more uncomfortable by late Tuesday and Wednesday. In fact, heat indices by Wednesday may approach 100. Stray showers/thunderstorms may come back into the picture as early as late-day Tuesday. From Wednesday-Friday, multiple weak disturbances will cross over-top a very hot and humid air-mass. The combination of these two will lead to daily thunderstorm chances and while it certainly won’t be raining at all times, we’ll have to be on guard for slow moving heavy storms given the weak flow and high moisture content. A better chance for more organized storms looks to come next Saturday with the approach of a cold front.
