The Lehigh Valley could get some rain Thursday night, as temperatures in the 70s give way to the 40s over the weekend, forecasters said.

Less than an inch of rain could fall late Thursday night into Friday as temperatures drop, according to the National Weather Service in Mount Holly, New Jersey. A high of 73 is expected Thursday, dropping to 43 Saturday, forecasters said.

Rain should stop by Friday morning in the Lehigh Valley, and temperatures should fall into the upper 20s Friday night. Temperatures will return to normal Sunday, with highs in the 50s.

There could be an “unsettled pattern” next week with the possibility of more rain.

“While it will be on the more mild and warmer side next week, there will be multiple chances for rain as several frontal systems slide by,” meteorologists wrote Thursday in their daily forecast discussion. “None of these systems look overly impactful at this point, but there could be some periods of rain, beginning late Monday and continuing off and on through the middle of the week.”

Temperatures in the 60s are possible early next week.
