Current Conditions and Alert Status

A Heat Advisory is currently in effect for the Sherman area, issued by the National Weather Service in Fort Worth. This moderate-severity alert remains active until 8:00 PM CDT tomorrow. As of this afternoon, the air temperature stands at 99F, but the combination of heat and humidity makes it feel like 102F.

Relative humidity is at 33%, with a dew point of 64F. The sky is clear, and winds are blowing from the south southeast at 13 mph, with gusts reaching 15 mph. These conditions contribute to the dangerous heat index values that are expected to peak at 104F later today.

Forecast for Today and Tonight

The day will remain sunny with a high near 101F. The chance of precipitation is minimal at 5%. As evening approaches, temperatures will drop to a low near 79F, though they may rise slightly to around 81F overnight.

The sky will be mostly clear tonight. Winds will ease to between 5 and 10 mph from the south southeast. Despite the drop in air temperature, heat index values will remain high, reaching as much as 104F, meaning the perceived heat will persist well into the night.

Outlook for Tomorrow

Tomorrow will bring similar conditions, with sunny skies and a high near 100F. The chance of rain is extremely low at 1%. Winds will shift to a south direction, ranging from 5 to 15 mph.

Heat index values are expected to reach 102F during the day. Tonight, temperatures will again fall to around 79F before rising to 81F, with mostly clear skies. Winds will be from the south southeast at 10 to 15 mph.

Given the sustained high heat index values, it is important to stay hydrated and limit outdoor exertion during the hottest parts of the day. Check on neighbors and ensure pets have access to shade and water.
