Current Conditions and Heat Index
Van Alstyne is experiencing a very hot and humid afternoon on Sunday. The air temperature currently stands at 88F, but the combination of heat and moisture makes it feel significantly warmer. The current feels-like temperature is 98F, driven by a relative humidity of 66% and a dew point of 75F.
