On Tuesday, residents of the Lehigh Valley may anticipate mostly cloudy skies and lower-than-normal temperatures, with highs in the upper 70s. The unusually chilly weather trend will be aided by a northeast breeze.
A persistent high-pressure system above southern Quebec is expected to push a windy northeast wind across the area, according to the National Weather Service forecast, keeping temperatures below normal for late August.
To the south, isolated light showers are likely over the Delmarva peninsula and southern New Jersey, especially in the morning. Partially sunny skies are predicted for Lehigh, Northampton, and Warren counties, with little chance of significant precipitation.
Northeastern winds of 5 to 10 mph will provide a chilly, humid atmosphere in the Lehigh Valley before turning east-southeast into Tuesday evening.
Seasonable low temperatures for this time of year are predicted to fall into the low 60s overnight. There is little chance of midday breaks due to the heavy cloud cover that is predicted.
Temperatures are expected to rise into the mid-seventies on Wednesday and Thursday, with showers and thunderstorms probable until the likelihood of precipitation decreases on Thursday.
Although specifics are yet unknown, a frontal system that is expected to move in during the weekend may bring more unstable circumstances.
By the end of the week, the extended forecast predicts more unpredictable weather as a frontal system moves in on Saturday night and Sunday, but it also predicts a return to more normal late summer temperatures.
Through Thursday, the greatest offshore effects of Hurricane Erin will be felt along the coast, where high surf, severe rip currents, and strong winds could cause beach erosion and tidal flooding.
