Rain is expected into Thursday afternoon while temperatures drop in the Lehigh Valley.
After several days of temperatures in the 60s and 70s, a cold front should drop highs into the 40s to end the week, according to the National Weather Service in Mount Holly, New jersey.
Showers will likely continue into the early afternoon, and there is a possibility of very light snow before precipitation stops, forecasters said. Highs will be in the 40s and 50s through the weekend and then into the 60s by Monday, according to the weather service.
These high temperatures will happen early today before colder air arrives. The temperatures by mid-afternoon will be mostly in the mid/upper 30s. Don’t dress for the temperatures we had the past few days. 🤨 pic.twitter.com/57cK22gEGN

Another cold front will bring rain, gusty winds and a “surge” of colder air, meteorologists wrote Thursday in their daily forecast discussion.
“This may result in high temperatures Tuesday and Wednesday reaching the upper 30s to low 40s across our region,” the wrote. “Winds chills will be in the 30s much of the time. Quite a difference from the recent spell of warmth.”

A high of 80 was recorded Tuesday, tying the record for that day and making it the third-earliest 80-degree day on record for the region.
