Current Conditions and Humidity

Residents in Van Alstyne are experiencing a notably humid start to the day this morning. The air temperature currently stands at 82F, but the heavy moisture in the atmosphere pushes the feels-like temperature up to 88F. Relative humidity is holding steady at 74%, with a dew point of 73F indicating significant saturation in the lower atmosphere.

Skies are currently clear, offering no immediate relief from the sun’s intensity. Winds are blowing from the south at 10 mph, with gusts reaching up to 20 mph. These breezes provide minimal cooling effect given the high moisture content.

There are no active National Weather Service or NOAA weather alerts in effect for this area. The primary concern remains the oppressive heat and humidity rather than severe storm activity.

Today will be sunny with a high near 99F. The National Weather Service indicates that heat index values could climb as high as 104 due to the combination of temperature and humidity. A south wind around 10 mph will persist throughout the day. The chance of precipitation is minimal at just 1%.

Tonight, conditions will remain clear with a low near 77F. However, temperatures are expected to rise to around 79F overnight, preventing any significant relief from the heat. Heat index values may reach 101 during this period. Winds will increase slightly to 10 to 15 mph from the south.

Tomorrow brings another sunny day with a high near 98F. The heat index is forecast to hit 103, maintaining hazardous conditions for prolonged outdoor exposure. South winds will continue at 10 to 15 mph. The chance of rain drops to 0% for tomorrow. Temperatures will fall to a low near 79F tonight, rising again to around 81F overnight.

Safety Reminder

Given the high heat index values exceeding 100 degrees, it is crucial to stay hydrated and limit midday exertion. Check on elderly neighbors or those without air conditioning.
