With record high temperatures forecast for this week, the National Weather Service has placed much of North Texas under a heat advisory for today and Monday.

Brown County just missed being included in the advisory, even though highs of 102 are expected in Brownwood, according to the San Angelo weather service office. But in Comanche, Mills and Eastland counties, high temperatures are predicted to be in the 104 to 109 range.

“These high temperatures combined with humidity will produce heat index values between 105 and 110 degrees during the late afternoon hours,” forecast J.L, Dunn of the Fort Worth NWS office said. “High temperatures on Monday will remain between 101 and 105 degrees with heat index values between 105 and 110 degrees”

Overnight low temperatures are expected to drop only into the upper or mid-70s, providing little recovery time from the daytime heat.

Anyone involved in outdoor activities is urged to take frequent breaks and drink plenty of water, and wear loose-fitting and light-colored clothing.

A slight chance of thunderstorms is in the forecast for this area Tuesday and Wednesday.
