After an exceptionally mild winter springtime temperatures have reverted closer to normal, and possibly a bit below normal, as evidenced by the fact that the National Weather Service has issued a freeze watch for the area for Thursday from 12 to 9 a.m.
According to the weather service’s latest forecast for the Lehigh Valley, Thursday’s low will be around 30 degrees, which is just below freezing.
“Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing,” the NWS noted in a hazardous weather outlook published Wednesday afternoon. “Take steps now to protect tender plants from the cold.”
In addition to Lehigh and Northampton counties, the freeze watch covers Upper Bucks, Western Montgomery and Berks counties in Pennsylvania, as well as parts of western New Jersey.
Temperatures are forecast to remain cool for the remainder of the week before returning to the 60s next week.
