Current Conditions and Alert Status

A Heat Advisory is currently active for Allen, issued by the National Weather Service in Fort Worth. This moderate-severity alert remains in effect until this evening. Residents are facing dangerous heat conditions right now, with the air temperature sitting at 97 degrees Fahrenheit.

However, the combination of heat and moisture means the temperature feels like 110 degrees. The relative humidity is at 50 percent, and the dew point stands at 75 degrees, creating an oppressively humid environment that makes the air feel heavy and sticky.

The sky is currently clear, and winds are blowing from the south southeast at 14 miles per hour, with gusts recorded at 11 miles per hour.

Today and Tonight Outlook

The forecast for the remainder of the day indicates sunny skies with a high near 101 degrees. Heat index values are expected to reach as high as 109 degrees, posing significant risks to those spending time outdoors. Winds will shift to around 10 miles per hour from the south southeast.

As night falls, conditions will remain mostly clear with a low around 80 degrees. The heat index will stay elevated, reaching up to 106 degrees, while winds ease to between 5 and 10 miles per hour. The lack of significant cooling overnight means the oppressive heat will persist into the early morning hours.

Tomorrow’s Forecast and Safety

Tomorrow will bring similar conditions, with sunny skies and a high near 101 degrees. Temperatures are expected to fall to around 99 degrees in the afternoon. The heat index will peak at 105 degrees.

Winds will come from the south at 5 to 10 miles per hour, with gusts potentially reaching 20 miles per hour. The chance of precipitation is low at 8 percent. Given the sustained high heat indices and humidity levels, it is crucial to stay hydrated and limit midday exertion.

Check on neighbors and vulnerable individuals who may not have access to air conditioning. Avoid prolonged exposure to direct sunlight, and seek cool, shaded areas or air-conditioned spaces during the hottest parts of the day.
