Date:
July 21, 2025
Forecast Period:
8:00 AM Today (July 21, 2025) through 8:00 AM Tomorrow (July 22, 2025)
Discussion:
A high pressure ridge continues to build westward. High heat and humidity today while the area is under a Heat Advisory from the National Weather Service. Maintain caution as category 5 heat stress will extend for multiple hours today. Tomorrow, a weak trough to the north will push a weak front southward into the area in the afternoon triggering widespread showers and thunderstorms with some potential to approach severe (marginal risk from the NWS).
Special Conditions:
Heat advisory in place. High temperatures and humidity will lead to heat illness if precautions are not taken.
