Area covered by excessive heat watch Thursday
The National Weather Service has issued an excessive heat watch for Thursday afternoon and evening for the Washington, D.C. metro region. High temperatures are forecast to reach the upper 90s to around 100 degrees, with heat index values of 105 to 110.

Thursday is forecast to be the first of three straight days when temperatures could reach triple digits, with heat indices in the 105-115 range. NOAA’s Hydrometeorological Prediction Center forecasts peak heat indices of 109, 109, and 110 Thursday, Friday, and Saturday.

The National Weather Service reminds us:

AN EXCESSIVE HEAT WATCH MEANS THAT A PROLONGED PERIOD OF HOT TEMPERATURES IS EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND HIGH HUMIDITY WILL COMBINE TO CREATE A DANGEROUS SITUATION IN WHICH HEAT ILLNESSES ARE POSSIBLE. DRINK PLENTY OF FLUIDS...STAY IN AN AIR-CONDITIONED ROOM...STAY OUT OF THE SUN...AND CHECK UP ON RELATIVES AND NEIGHBORS.
