The Lehigh Valley could get some light rain Wednesday during what has been a relatively dry period for the region.
Rain is possible starting early Wednesday morning and throughout the day, but not much rainfall is expected, according to the National Weather Service in Mount Holly, New Jersey. Forecasters are expecting between .01 and .1 inches of rain by the end of the day Wednesday.
Thunderstorms also are possible. Rain should taper off at night, which forecasters said should be calm.
Heavier rainfall is expected more to the south of the region, in Bucks County and Philadelphia. About a half an inch of rain is possible there. After Wednesday, the Lehigh Valley likely will be dry through at least Monday, according to forecasters.
A little over 2 inches of rain have fallen so far this month, with the bulk of the rainfall happening at the beginning of the month. It’s been nearly a week since the last measurable rainfall in the Lehigh Valley.
Good morning! We'll see some beneficial rainfall across at least parts of the area over the next day or two due to a coastal low to our south. The heaviest amounts will be near the coast with amounts tapering off as you head northward. pic.twitter.com/pW6yj5MlsK
