Current Conditions and Humidity

The air in Van Alstyne feels heavy this afternoon, with a notable level of moisture lingering in the atmosphere. The current dew point sits at 72F, contributing to a relative humidity of 62%. While the actual air temperature is 86F, the combination of heat and humidity pushes the feels-like temperature up to 92F. Skies remain mostly clear overhead, offering little relief from the sun’s intensity. Winds are currently light, blowing at 8 mph with gusts reaching 7 mph, which is insufficient to disperse the stagnant, muggy air.

Forecast for Today and Tonight

Conditions are expected to remain consistent through the rest of the day. The high will stay near 86F, matching the current reading, before dropping to a low near 73F tonight. There is no chance of precipitation, with the sky staying sunny during the day and becoming mostly clear after sunset. Winds will shift slightly, coming from the south southeast at speeds between 5 to 10 mph as the evening progresses. Despite the drop in temperature, the humidity will likely persist, keeping the night feeling warm and sticky.

Tomorrow’s Heat and Wind

Temperatures will climb significantly by tomorrow, with a high near 90F. The heat index is forecast to reach as high as 99F, making it feel much hotter than the actual air temperature. Skies will be mostly sunny, providing ample opportunity for the sun to intensify the heat. Winds will pick up considerably, coming from the south at 10 to 20 mph, with gusts as high as 30 mph. This increase in wind speed may help lower the heat index slightly by evening, but the air will remain warm. Overnight, temperatures will settle near 75F, with the heat index staying as high as 98F. Winds will continue from the south southeast at 10 to 20 mph, with gusts up to 30 mph, keeping the night humid and breezy.

Safety Reminder

With heat indices approaching 100F, it is crucial to stay hydrated and limit time spent outdoors during the hottest parts of the day. Wear lightweight, light-colored clothing and seek air-conditioned environments when possible. Keep an eye on how the body feels, as the combination of high heat and humidity can lead to heat-related illnesses quickly.
