By Justin Drabick,

This first official weekend of summer ended up very pleasant with near average temperatures and low humidity.  Average highs this time of year are in the low 80s.  A trough or dip in the jet stream over the northeast this weekend has kept a cooler and drier air mass in place.  As we move into the workweek the jet stream pattern will change a bit.

A developing storm system will track towards the Great Lakes sending a warm front to our area.  Expect some clouds around on Monday with warmer temperatures in the mid to upper 80s.  Humidity levels will begin to rise as the front approaches.  The warm front passes through the Delaware Valley on Tuesday providing hot and humid conditions.  If enough sunshine develops, highs will make it into the low 90s.  There will be a chance for showers and storms during the afternoon and evening as the next cold front approaches.

The cold front clears the Delaware Valley Tuesday night, allowing cooler and drier air to return to the region.  Mostly sunny skies return on Wednesday as northerly winds cool temperatures back into the 80s with lower humidity.  Thursday remains very nice and comfortable with sunshine and highs in the mid 80s.  Some more heat begins to build on Friday into the holiday weekend with highs in the upper 80s on Friday and low 90s on Saturday.  A scattered shower or storm is possible Saturday night.  Right now, I don’t see any long periods of high heat and humidity during the next week or so.  Have a great week!
