Very hot pattern holds

Allen is in a very warm and clear setup, and the main weather story is heat. The current air temperature is 78F, with a feels-like reading of 79F. Relative humidity is 71%, and the dew point is 68F. Wind is 5 mph, with gusts to 17 mph, under a clear sky.

The heat will build quickly into today, with sunshine and a high near 100F. The chance of precipitation is just 1%, so rain is not expected to offer meaningful relief. Heat index values may reach as high as 102, making it feel even hotter than the air temperature at times.

Today will be sunny, with south wind 5 to 10 mph. The low is near 80F.

Tonight stays clear, with a low around 80F and temperatures rising to around 82F overnight. Heat index values may be as high as 103, and south wind is around 10 mph.

Tomorrow remains sunny and very hot, with a high near 99F and a low near 79F. The chance of precipitation increases to 14%, but the forecast still keeps the day sunny. Heat index values may again reach as high as 103, with south wind 5 to 10 mph.

Alerts and safety

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

Even without an alert, this level of heat can be taxing. Drink water, take breaks from strenuous activity, and do not leave people or pets in parked vehicles.
