Meteorologist Myles Henderson’s First Warning Forecast

A warm and muggy week… Highs will climb to near 90 this afternoon, about 5 degrees above normal for this time of year. It will feel more like the mid to upper 90s with the humidity. Expect a mix of clouds, partly to mostly cloudy, with an isolated shower or storm possible. It will be breezy today with SW winds at 10 to 15 mph.

Highs will return to the low 90s tomorrow with an afternoon heat index in the upper 90s. We will start with clouds in the morning, but skies will clear through the day.

Temperatures will dip into the upper 80s on Wednesday with slightly lower humidity. We will see a nice mix of sun and clouds with an isolated shower/storm possible. Heat and humidity will build for the end of the work week. Highs will climb to the low and mid 90s with afternoon heat index values in the triple digits.

The biggest rain chance this week is set for Saturday. The leftovers of Tropical Storm Laura will be pushed over the Mid-Atlantic by a cold front.

Tonight: Mix of Clouds, Isolated Shower/Storm. Lows in the mid 70s. Winds: SW 5-10
