If you are missing warmer weather and Sunday’s cool and breezy day isn’t working for you, the beginning of the work week will be a welcome relief.

Monday and Tuesday will not only be sunny, but high temperatures will rise into the 70s in the Lehigh Valley with the possibility of passing 80.

However, things will likely change back in the middle of the week as rainy weather returns, though temperatures shouldn’t take a big dive.

“As high pressure shifts further away on Tuesday, a low passing well to the north may bring a few showers late Tuesday into Tuesday night for areas northwest of the I-95 corridor,” the National Weather Service in Mount Holly, New Jersey said in its forecast discussion. “A cold front then approaches from the west on Wednesday and will stall out over the area.”

An area of low pressure will also come up from the southeast which will result in widespread rain for at least two days. Thunderstorms are a possibility.

“Precipitation likely will come in multiple waves Tuesday night through Thursday,” the NWS said. “The first wave will be with the incoming cold front mainly late Tuesday into Wednesday. The second wave would come more toward Wednesday night and Thursday as the area of low pressure slides through.”

Sunny weather is expected back on Friday with temperatures in the 60s.
