Lehigh Valley Weather: After storms this weekend could see the first 90 degree day of 2021
Following scattered thunder, the Lehigh Valley could experience its hottest day of the year yet.
Thursday’s Lehigh Valley weather forecast predicted a high of 89 degrees on Sunday, which would make Wednesday for 2021 the hottest yet. But, noted National Weather Service meteorologist Michael Silva, “it won’t take much to raise it one more degree.”
If that happens, it would be pretty much on schedule. On average, the first 90-degree day of a year here is observed around May 30 – this happened as early as April 7, according to weather service records.
The Lehigh Valley has not had a 90-degree day since August 27.
Over the past century, the Lehigh Valley has averaged 17 days a year at 90 degrees or more. There were as many as 41 (in 1966) and as few as one (in 1960).

If that doesn’t happen on Sunday, next Wednesday will be another good chance to cross the 90-degree mark, Silva said.
But before Sunday’s heat, we’ll have to deal with a few widely scattered showers and thunderstorms on Saturday.
Silva said most people probably won’t see the rain. But where storms do arise, he warned they would have the potential to be strong.
