Active Alert and Current Conditions

An Extreme Heat Warning is currently in effect for Van Alstyne, Texas. This severe alert indicates dangerous heat conditions that require immediate caution. As of this Wednesday morning, the air temperature stands at 82F, but the humidity makes it feel significantly warmer.

The feels-like temperature is currently 89F, driven by a relative humidity of 79% and a dew point of 75F. These moisture levels create an oppressively humid atmosphere that intensifies the perceived heat.

The sky is currently clear, and winds are calm at 0 mph, though gusts may reach up to 11 mph. While the current conditions are already uncomfortable, the forecast indicates a significant escalation in heat intensity over the next several hours.

Forecast for Today and Tomorrow

Today, the sun will remain out with a high near 100F. The National Weather Service reports heat index values as high as 110F during the day. Northeast winds will pick up slightly, blowing at 5 to 10 mph. The chance of precipitation is minimal at just 2%, leaving the sky sunny and dry.

Tonight, conditions will remain clear with a low around 76F. Despite the drop in air temperature, the heat index will remain elevated, with values as high as 107F. Winds will shift to the east northeast, maintaining speeds of 5 to 10 mph. This means the oppressive heat will linger well into the night, offering little relief.

Tomorrow, the heat will persist but with a slight decrease in peak temperatures. The high will be near 96F, with heat index values reaching up to 102F. Skies will remain sunny, and east winds will blow around 10 mph.

The chance of rain is negligible at 1%. Tomorrow night, the sky will be mostly clear with a low around 76F and a heat index of 99F.

Safety Reminder

Given the Extreme Heat Warning and heat index values exceeding 100F, it is critical to stay hydrated and limit time spent outdoors, especially during midday hours. Check on elderly neighbors and ensure pets have access to cool, shaded areas. Avoid strenuous activity during the hottest parts of the day to prevent heat-related illnesses.
