Severe Heat Alert in Effect
Sherman is currently operating under an active Extreme Heat Warning issued by the National Weather Service. This severe alert remains in effect until tomorrow evening. The immediate danger is driven by the combination of high air temperatures and low humidity, which creates dangerous heat index values.
Right now, the air temperature is 102F, but the feels-like temperature has reached 105F. The relative humidity is only 28%, and the dew point is 63F. Winds are light at 5 mph with gusts up to 12 mph, and the sky is clear.
This lack of cloud cover and moisture allows the sun to intensify the heat throughout the afternoon.
Today and Tonight Outlook
For the remainder of today, conditions will remain mostly sunny with a high near 104F. The heat index values will peak at 105F. South winds will stay around 5 mph.
As night falls, the sky will remain mostly clear. Temperatures will drop to a low near 82F, though they may rise slightly to around 84F overnight. The heat index will still reach 104F during the night, meaning the air will not provide significant relief.
Winds will shift to the south-southeast at 5 to 10 mph. Residents should be aware that the heat persists well into the evening hours.
