Strong winds from the north will bring cooler temperatures and gusty conditions to the Lehigh Valley on Thursday, with gusts potentially reaching 25-35 mph during the afternoon.

Afternoon high temperatures will range from mid-50s to low 60s, with significantly lower humidity and dry conditions.

The National Weather Service forecasts clear skies throughout the day, with northerly winds creating a tightening pressure gradient across the region.

Dew points will drop into the mid-20s to low 30s, creating very dry air conditions. While fire weather concerns remain low, residents should be prepared for brisk, chilly winds that will make outdoor activities feel considerably cooler.

Overnight temperatures are expected to drop into the mid-30s to low 40s, with the growing season officially ending for the Lehigh Valley and Pocono Mountains regions. The clear skies and diminishing winds may allow for some radiational cooling, particularly in sheltered locations. Current wind conditions, however, are not expected to trigger a frost advisory for the southern Poconos or Lehigh Valley.

Looking ahead, temperatures will gradually moderate, with Saturday expected to be slightly warmer.

A significant weather pattern shift is anticipated Sunday night into Monday, when a strong cold front will cross the area, potentially bringing scattered showers and a more pronounced temperature change.

Residents should dress in layers and be prepared for windy, cool conditions throughout Thursday and Friday, with outdoor activities potentially impacted by persistent northerly winds.
