The Lehigh Valley’s residents may anticipate largely overcast skies with the possibility of showers and thunderstorms starting Wednesday afternoon.
There are currently no severe weather alerts for Warren, Northampton, or Lehigh counties.
A slow-moving frontal boundary is expected to move northward through lunchtime, bringing with it the possibility of isolated thunderstorms and localized heavy rainfall, according to the National Weather Service forecast. With easterly breezes of around 10 mph, temperatures will rise to the mid-seventies.

As diurnal instability increases, scattered showers are most likely to occur in the afternoon. With high precipitable water levels of 1.7 to 2 inches, there is a chance of tropical-style downpours. Depending on the precise location of the frontal boundary, isolated locations may see brief localized flash flooding, but widespread flooding is not anticipated.
The forecast for Thursday calls for more cloudy skies and highs in the low to mid-seventies. Hurricane Erin will pass offshore and deliver breezy northeast winds of 10 to 15 mph with gusts of up to 20 to 30 mph to the area, which is in its peripheral effect zone.
Through Thursday, Erin is expected to create high surf, life-threatening rip currents, minor to major tidal flooding, and gusty gusts along the coast.

With high pressure moving in and temperatures cooling, the Lehigh Valley’s weekend forecast appears more optimistic. After the erratic midweek circumstances, a lovely conclusion to the week is anticipated on Friday, with partly to mostly sunny skies and highs in the low to mid-80s.
