We’re going to get some welcome relief to the brief warm spell we’ve had so far this week, as a large area of showers over Pennsylvania will move east slowly during the course of the day today. You can already feel a change in the air, with temperatures generally 10 degrees (or more) cooler this morning than at this time yesterday.

Friday – the cold front responsible for bringing us showers today will move through to our south and usher in a cool, dry air mass from Canada in its wake. High pressure will then build over Quebec and dominate the area through at least Monday. Temperatures will be pleasant near 80 with mostly sunny skies.

Saturday and Sunday – the pattern of pleasant, mild and seasonable temperatures will set the stage for the formal beginning of summer (Saturday, June 21st is the day of the summer solstice, the longest day of the year). Temperatures both days will range in the upper 70s to low 80s, with low humidity and sunny skies.

Monday and Tuesday – this stretch of nice weather continues into the beginning of the next work week, with high pressure slowly moving off to the east, but still warm and nice. Temperatures again will be in the low 80s with mostly sunny skies.

Our next chance at rain will come Wednesday with a cold front associated with a two storms systems that will merge (one over the Mississippi Valley, the other moving from Ontario).
