The advisory highlights the significant risk associated with prolonged exposure to high heat and humidity levels across the region.

As of this evening, the air temperature stands at 91F, but the combination of heat and moisture makes it feel like 96F. Relative humidity is at 46%, with a dew point of 68F. Winds are blowing from the south at 8 mph, with gusts reaching up to 19 mph. The sky remains clear, offering no relief from the sun’s intensity.

Forecast for Today and Tomorrow

Today, residents can expect a high near 98F under clear skies. There is a zero percent chance of precipitation, meaning dry conditions will persist throughout the day. Overnight tonight, temperatures will drop to a low near 79F, though they may rise slightly to around 81F later in the night.

The National Weather Service notes that heat index values could reach as high as 103 during this period. South winds will continue at 10 to 15 mph.

Tomorrow brings even more intense heat, with a high near 100F and sunny skies. The chance of rain remains negligible at just 1%. Heat index values are forecasted to climb as high as 108, making it feel significantly hotter than the actual air temperature.

Winds will remain steady from the south at 10 to 15 mph. Tomorrow night, conditions will clear again with a low around 80F, potentially rising to 82F overnight, with heat indices up to 104.

Safety Reminders

Given the active Heat Advisory and extreme heat index values, it is crucial to take precautions. Stay hydrated by drinking plenty of water throughout the day. Limit outdoor exertion, especially during the midday hours when temperatures peak. Check on elderly neighbors or those without air conditioning to ensure their safety. If you must be outside, seek shade frequently and wear lightweight, light-colored clothing.
