Meteorologist Myles Henderson’s First Warning Forecast

Not as hot but more storm chances… Finally a break from the extreme heat. Expect highs today near 90, still about 5 degrees above normal but better than earlier this week. Heat index values this afternoon will reach into the upper 90s to near 100. We will see a mix of sun and clouds today with scattered showers and storms as a stationary front slowly slides through the region. The best window for storms will be this afternoon to early evening. Severe storms are not expect but heavy downpours and lightning are possible.

The stationary front will slowly push into the Carolinas on Friday, keeping the chance for scattered showers and storms. Highs tomorrow will slip into the upper 80s. Expect mid to upper 80s for the weekend. The stationary front and its leftovers as it falls apart will combine with a small area of low pressure off of the Carolina coastline to keep a mix of clouds and the chances for scattered showers and storms. No day looks to be a washout but we will have several opportunities for showers/storms to end the week, over the weekend, and into the start of next week.

Today: Partly Sunny, Scattered Showers/Storms(40%). Highs near 90. Winds: W 5-10

Tonight: Partly Cloudy, Scattered Showers/Storms(30%). Lows in the mid 70s. Winds: SW 5-10

Tomorrow: Partly Sunny, Scattered Showers/Storms(30%). Highs in the upper 80s. Winds: W/N/E 5-10
