Current Conditions and Air Quality

An active Air Quality Alert is currently in effect for the Allen area, issued by the National Weather Service. While the severity and urgency details are not specified, residents should remain aware of potential respiratory impacts. The current atmosphere is notably muggy, with an air temperature of 79 degrees Fahrenheit.

The combination of high relative humidity at 84 percent and a dew point of 73 degrees Fahrenheit creates a feels-like temperature of 82 degrees. The sky remains clear, and winds are blowing from the south southeast at 8 miles per hour, with gusts reaching 10 miles per hour. This humid environment can make the air feel heavier than the actual temperature suggests.

Today and Tonight Outlook

For the remainder of today, conditions will remain mostly sunny with a high near 91 degrees. There is a slight chance of showers and thunderstorms developing after 4 p.m., with the overall chance of precipitation estimated at 17 to 20 percent. Winds will vary between 0 and 10 miles per hour.

As night falls, a slight chance of storms may persist before 7 p.m. The sky will become partly cloudy, and temperatures will drop to a low around 73 degrees. Southeast winds will range from 5 to 10 miles per hour during the evening hours.

Tomorrow's Forecast and Safety

Tomorrow will be warmer, with a high near 94 degrees and a low around 74 degrees. The sky will be mostly sunny, but the heat index values could reach as high as 99 degrees. This significant increase in perceived heat requires caution.

Winds will shift to the south southeast, ranging from 5 to 15 miles per hour, with gusts potentially reaching 25 miles per hour. The chance of precipitation drops to 10 percent. Given the high heat index and humidity, it is advisable to stay hydrated and limit strenuous outdoor activities during the peak afternoon hours.

Check on elderly neighbors or those with respiratory conditions, especially given the active air quality alert.
