Current Conditions and Alert Status

Residents in Allen are currently under a Heat Advisory issued by the National Weather Service. This moderate severity alert remains in effect until early tomorrow evening. As of this afternoon, the air temperature stands at 95 degrees Fahrenheit, but the combination of heat and humidity creates a dangerous feels-like temperature of 101 degrees.

The relative humidity is currently 44 percent, with a dew point of 70 degrees. Winds are light, blowing from the southeast at 7 miles per hour with gusts reaching 9 miles per hour. The sky is mainly clear, offering little relief from the direct solar radiation.

Today and Tonight Outlook

Tonight, conditions will stay mostly clear with a low around 79 degrees. Despite the drop in air temperature, heat index values will remain elevated, reaching as high as 104 degrees. Winds will shift to the south-southeast, ranging from 0 to 10 miles per hour.

Tomorrow and Safety Reminders

Tomorrow will bring similar conditions, with sunny skies and a high near 101 degrees. The low is expected to be around 80 degrees, and the chance of rain is only 3 percent. Heat index values will again peak at 106 degrees.

Winds will be from the east-southeast, varying between 0 and 10 miles per hour. Given the sustained high heat indices, it is crucial to stay hydrated and limit outdoor exertion during the hottest parts of the day.
