Heat remains the main concern

Dangerous heat is the main weather story in Allen this afternoon, with the air temperature at 99F and a feels-like reading of 102F under a clear sky. Relative humidity is 33%, and the dew point is 64F. Wind is 12 mph, with gusts to 14 mph.

The forecast keeps the heat near the century mark today, with a high near 100F and sunshine. The chance of precipitation is 1%, so meaningful rain is not part of the outlook. Heat index values could rise as high as 104F today, adding to the strain for anyone spending time outside.

Today, tonight and tomorrow

Tonight remains warm and mostly clear, with a low near 80F. Heat index values as high as 102F are in the forecast, and south southeast wind is around 10 mph.

Tomorrow brings another sunny and hot setup, with a high near 99F and a low near 80F. The chance of precipitation is again 1%. Heat index values may reach as high as 102F, with south southwest wind 5 to 10 mph.

Alerts and heat safety

There are no active NWS/NOAA weather alerts listed for Allen.

Even without an alert, this level of heat can wear people down. Drink water, take breaks in shade or air conditioning when possible, and limit strenuous outdoor activity when the heat feels strongest. Check on people and pets who may be more vulnerable to heat, and do not rely on a quick breeze to offset the conditions.
