Weather Forecast Discussion

A little rain tonight, mainly south and east

Rainy and cooler on Thursday

TONIGHT: Mostly cloudy with a bit of rain, mainly south and east of the Lehigh Valley. Low: 54

WEDNESDAY: A damp start, then clouds breaking for some sunshine. High: 75

WEDNESDAY NIGHT: Becoming cloudy with rain overspreading the area after midnight. Low: 56

The skies did brighten at times on Tuesday, but overall it was a mostly cloudy day. The clouds never allowed the temperatures to take off, so mid and upper 60s was as good as it got. A little rain also made its way in from the south Tuesday afternoon. That rain will continue at times overnight, especially late and in areas south and east of the Lehigh Valley. Otherwise, skies will be rather cloudy overnight as temperatures fall into the mid 50s.

A little lingering rain will be around first thing Wednesday morning, again mainly south and east of the Lehigh Valley. The wave of low pressure associated with the rain will quickly exit the East Coast by midday. At the point, look for the rain to end and the morning clouds to give way to some sunshine. Temperatures on Wednesday will extend into the mid 70s. The clouds will lower and thicken again Wednesday night prior to another round of rain moves in closer to daybreak Thursday.

The rain that moves in late Wednesday night will then continue on-and-off throughout the day on Thursday with a thunderstorm possible in spots. Temperatures on Thursday will be cooler as a result of the rain and the clouds, so mid 60s is as high as temps will climb. Late in the day and at night on Thursday is when the rain will taper back to showers. Rainfall totals will generally be between .50" and 1.0" with locally higher amounts possible. 

Friday will still have more clouds than sun, but it will be a drier day overall with just a spotty shower or two. High temperatures will be seasonable in the low 70s.

The unsettled pattern continues into the Memorial Day Weekend, but we will see improvements. While showers and a thunderstorm can't be ruled out Sunday and Monday, Saturday looks dry. This weekend will also be warmer as daytime highs end up in the upper 70s.
