Quiet and crisp transition from summer to fall this weekend

Cloudy and drizzly to start next week

TODAY: Pleasant with times of clouds and sunshine. High: 71

TONIGHT: Partly to mostly cloudy and cooler with some rain possible south of the Lehigh Valley late. Low: 56

SUNDAY: Cool with more clouds than sun. High: 70 Low: 53

Welcome to the last "day" of summer, southeastern Pennsylvania and western New Jersey! The astronomical calendar will officially flip from summer to fall at 9:54 tonight, but jugs of apple cider are already ripe for pickin' up at your local grocery stores. Somewhere near the pumpkin rolls we suspect. We're not hungry. You're hungry.

Anyways... 

Mother Nature will send summer off in a quiet and comfortable fashion, fitting for fans of autumn-like air. This morning's cold front will shoe away humidity as dew points fall into the 50s. After an early morning shower southeast of the Lehigh Valley, skies will be dressed in clouds and filtered sunshine. It's pretty much pumpkin-perfect until clouds thicken up tonight.

That same boundary responsible for more pleasant air is pinned just south of the state. Waves of low pressure will use it as a highway, driving some rain showers especially south of the Lehigh Valley late tonight and Sunday. Points near and south of the front will be covered in clouds, while an easterly component to our wind means the chance for significant sunshine north of the front isn't one we're willing to bet too much on. It's there though, and we'll hope for the best and brightest outcome for friends closer to the Lehigh Valley and Poconos. Highs near 70 degrees may be out of reach if clouds win out Sunday. Lows in the lower 50s will allow for some natural cooling at night.

Cloudy, cool, and drizzly will be the theme for the beginning of the work week as winds turn due east, pumping Atlantic moisture into the area. We've seen this set up time and time again--and it's not the set up for considerable sunshine if any at all. High temperatures Monday and Tuesday will max out in the upper 60s for this reason. Air will warm up as winds adopt a southwesterly approach mid to late week. That's when we're forecasting better odds for some sun and highs in the middle to upper 70s.

Wishes for a wonderful weekend!
