Central U.S

It's back! Heat and humidity has returned to the Plains this week. The heat index will climb above the century point this week in most areas. Heat alerts extend from Wisconsin to Texas.

Temperatures will return to near average by Saturday. Temperatures will slowly trend downward into next week, even a few degrees below average for this time of year. Be sure to practice heat safety this week. Check on elderly or ill neighbors, never leave children or pets unattended in a vehicle, avoid strenuous work during the heat of the day, take frequent breaks and stay hydrated!

Northeast Heat

The heat continues to spill into the northeastern United States too. Heat advisories are in place for the next couple of afternoons. In pink, excessive heat warnings are in place across New Jersey and into Pennsylvania. For many, Thursday afternoon will be the warmest day of the week.
