Muggy Conditions Persist

Residents in Allen are waking up to notably humid air as the week begins. Current readings show an air temperature of 79F, but the moisture in the atmosphere makes it feel warmer at 82F. The relative humidity sits at a heavy 79%, with a dew point of 72F indicating significant stickiness.

Winds are blowing from the south at 9 mph, occasionally gusting up to 20 mph under mostly clear skies.

Heat and Humidity Ahead

The heat will intensify quickly as the sun rises. Today is forecast to be sunny with a high near 99F. While the air temperature itself reaches that peak, the combination of heat and humidity will push heat index values as high as 104F. South winds will pick up slightly, ranging from 10 to 15 mph. The chance of precipitation is negligible at just 1%.

Overnight tonight, skies will remain clear. Temperatures will drop to a low around 78F initially, though they may rise to around 80F later in the night as humidity lingers. Winds will continue from the south at around 10 mph, with gusts potentially reaching 25 mph.

Tomorrow brings little relief from the warmth. The day will be sunny with a high near 98F. Heat index values are expected to climb back up to 104F. South winds will persist between 10 and 15 mph, with gusts as high as 25 mph. Overnight tomorrow night, conditions will remain clear with a low around 81F.

Safety Reminder

With heat index values reaching the upper 100s, it is crucial to stay hydrated and limit strenuous outdoor activities during the peak afternoon hours. Check on elderly neighbors or those without air conditioning, as the humidity can make indoor spaces feel warmer than the thermometer reads. Keep an eye on local updates for any changes in conditions.
