Current Conditions and Notable Humidity

It is currently Sunday this morning in Allen, TX, and the air is already feeling heavy with moisture. The current air temperature sits at 81F, but the relative humidity of 74% and a dew point of 72F make it feel significantly warmer, with a feels-like temperature of 85F.

Winds are blowing from the south southwest at 9 mph, with gusts reaching up to 21 mph, while the sky remains clear.

The notable condition driving the current discomfort is the high humidity. A dew point of 72F indicates a muggy atmosphere that will linger through the day. This moisture level contributes to the elevated heat index values expected later, making the air feel oppressive even before the peak heat arrives.

Today and Tomorrow Forecast

Today, the sun will dominate the sky with a high near 99F. The National Weather Service forecasts heat index values as high as 103 due to the combination of heat and humidity. South southwest winds will persist at 5 to 10 mph. There is only a 3% chance of precipitation, so residents should expect dry, sunny conditions.

Tonight, skies will remain clear with a low around 79F. However, temperatures will rise to around 81F overnight, keeping the heat index values as high as 103. South southeast winds will average around 10 mph. The humidity will not break, meaning the night will offer little relief from the daytime warmth.

Tomorrow, the pattern continues with sunny skies and a high near 99F. Heat index values will reach as high as 102. South winds will blow around 10 mph, with gusts as high as 20 mph. The chance of precipitation drops to just 1%. Tomorrow night will be clear with a low around 80F and similar heat index concerns.

Safety Reminder

With temperatures and heat indices in the low 100s, it is crucial to stay hydrated and limit midday exertion. Check on neighbors, especially the elderly or those without air conditioning, to ensure they are safe in the heat. Keep vehicles parked in the shade when possible, as interior temperatures can rise rapidly.
