Meteorologist Myles Henderson’s First Warning Forecast

Extreme heat is making a comeback… Highs will reach to near 90 this afternoon but with the humidity it will feel more like the mid 90s. Expect a nice mix of sun and clouds with an isolated shower or storm possible. Temperatures will drop into the mid 70s tonight with mainly clear skies.

Heat and humidity will climb to end the week. Highs will return to the mid and upper 90s Thursday through the weekend. With the humidity, heat index values will reach into the triple digits each afternoon. It will feel like 105 to 110 for Friday and the weekend. We will see plenty of sunshine with a few clouds mixing in. A “pop-up” shower or storm is possible but most areas will stay dry.

Today: Partly Cloudy, Isolated Showers/Storms (20%). Highs near 90. Winds: SW/S 5-10

Tonight: Partly Cloudy. Lows in the mid 70s. Winds: S 5-10

Tomorrow: A Few Clouds, Hot & Humid. Highs in the mid 90s. Winds: SW/S 5-10

Some slow development of this system is possible during the next day or two while it moves toward the WNW at 10 to 15 mph. After that time, environmental conditions are forecast to become unfavorable for development.
