Meteorologist Myles Henderson’s First Warning Forecast

***A Heat Advisory is in effect until 7 PM for all of Hampton Roads and most of Northeastern North Carolina. Afternoon heat index values will likely top 105 for many locations.***

Extreme heat continues… Highs will reach the mid 90s today, about 10 degrees above normal for this time of year. With dew points in the mid 70s, it will feel 10 to 15 degrees hotter this afternoon. Expect heat index values between 105 and 110 for most areas. We should see a mix of sun and clouds again today with a “pop-up” shower or storm possible this afternoon.

The good news… Today will be the hottest of the next 7 days. The bad news… Wednesday will be almost as hot. Expect highs in the low to mid 90s on Wednesday with afternoon heat index values near 105. We should see plenty of sunshine during the day but rain chances will increase Wednesday evening as a front starts to move in.

The front will slowly drag through the region from late Wednesday through Thursday and into Friday. Expect more clouds with scattered showers and storms. Our highest chance for showers and storms will be Thursday. The front will also bring a break from the extreme heat. Expect highs in the upper 80s to end the work week.

Today: Partly Cloudy, Isolated Showers/Storms(20%). Highs in the mid 90s. Winds: SW/S 5-15

Tonight: Partly Cloudy, Stray Showers/Storms(10%). Lows in the upper 70s. Winds: S/SW 5-15

Tomorrow: Partly Cloudy, PM Scattered Showers/Storms(30%). Highs in the low to mid 90s. Winds: SW 5-15
