Severe Heat Warning in Effect

Melissa is currently under an Extreme Heat Warning issued by the National Weather Service. This severe alert remains in effect until tomorrow evening. The dangerous heat is already evident, with the air temperature sitting at 100F and the feels-like temperature reaching 105F.

The sky is clear, and winds are light at 7 mph with gusts to 8 mph. Relative humidity is 33%, and the dew point is 66F. These conditions create a significant risk for heat-related illness, particularly for those spending time outdoors.

Today and Tonight Outlook

Today will remain sunny with a high near 104F. Heat index values are expected to climb as high as 108F, making the air feel significantly hotter than the actual temperature. Winds will be from the south southwest at around 5 mph.

The chance of precipitation is low at 9%. Tonight, the sky will be mostly clear with a low near 80F. Temperatures may rise slightly to around 82F overnight.

There is a slight chance of showers and thunderstorms between 7 pm and 10 pm. Heat index values will remain high, reaching up to 105F. Winds will shift to the south at around 5 mph.

Tomorrow's Forecast and Safety

Tomorrow will follow a similar pattern, starting sunny with a high near 104F. Heat index values will again reach as high as 108F. A slight chance of showers and thunderstorms is possible after 4 pm.

The overall chance of precipitation is 20%. Winds will be from the south southwest at around 5 mph. Given the sustained high temperatures and heat indices, it is crucial to take precautions.

Limit outdoor exertion during the hottest parts of the day, stay well-hydrated, and check on vulnerable neighbors. Avoid leaving pets or children in unattended vehicles, as interior temperatures can rise rapidly in these conditions.
