Meteorologist Myles Henderson’s First Warning Forecast

Weekend storm chances… A stationary front will linger over the Mid-Atlantic for the next few days, keeping rain and storm chances in the forecast. Expect some sun this morning with clouds increasing this afternoon. Scattered showers and storms will fire up this afternoon and continue into tonight. Our severe threat is low but heavy downpours and lightning are possible. Highs today will reach just above average into the upper 80s.

The front will stay over the Carolinas on Saturday, keeping us under a mix of sun and clouds with scattered showers and storms. Highs Saturday will fall slightly into the mid 80s. A cold front will build in for Sunday, increasing rain and storm chances for Sunday afternoon and night. Highs will climb to near 90 before the front moves in.

Showers should clear out Monday morning with sunshine returning Monday afternoon. Even cooler temperatures will move in next week with highs in the low to mid 80s.
