Current Conditions and Alert Status

A Heat Advisory is currently in effect for Allen, issued by the National Weather Service in Fort Worth. This moderate-severity alert is expected to remain active until this evening. The primary concern is dangerous heat, with the current air temperature sitting at 97 degrees Fahrenheit.

However, the combination of heat and humidity creates a feels-like temperature of 104 degrees. The relative humidity is 42 percent, and the dew point is 70 degrees, contributing to the muggy conditions. Winds are blowing from the south southeast at 9 miles per hour, with gusts reaching 10 miles per hour.

The sky is currently clear, allowing direct sunlight to intensify the heat.

Today and Tonight Outlook

For the remainder of today, conditions will remain sunny with a high near 100 degrees. Temperatures are expected to fall to around 98 degrees in the afternoon, but heat index values will climb as high as 104 degrees. The chance of precipitation is low at 5 percent.

Tonight, the sky will be mostly clear, with lows near 79 degrees. Interestingly, temperatures may rise to around 81 degrees overnight, keeping heat index values near 101 degrees. Winds will shift to 5 to 10 miles per hour from the south southeast.

Tomorrow and Safety Reminders

Tomorrow will bring mostly sunny skies with a high near 99 degrees. Temperatures are expected to dip to around 97 degrees in the afternoon, but heat index values could reach 105 degrees. The chance of precipitation increases slightly to 13 percent.

Winds will be lighter, around 5 miles per hour from the south southeast. Given the sustained high heat index values, it is crucial to take standard safety precautions. Residents should drink plenty of water, limit midday outdoor exertion, and check on elderly neighbors or those without air conditioning.

Avoid leaving pets or children in parked vehicles, as interior temperatures can rise rapidly in these conditions. Stay informed and prioritize hydration throughout the day and into the evening.
