Severe thunderstorm watch issued for Tuesday

A severe thunderstorm watch is in effect across Central Maryland on Tuesday evening, with risks of hail and damaging winds.

Some severe storms formed by about 6 p.m., with storm warnings in Montgomery and Frederick counties and in Kent, Queen Anne's and Caroline counties on the Eastern Shore. Strong storms were meanwhile moving across Carroll, Baltimore and Harford counties.

The severe thunderstorm watch was in effect through 9 p.m.

"The main threats will be hail and lightning. Damaging wind gusts could accompany any of the thunderstorms, especially through early evening," the National Weather Service said in a statement. 

Humidity was forecast to surge for the middle of the week, with highs in the upper 80s Tuesday and storm chances both Tuesday and Wednesday. Temperatures surged to 90 degrees Tuesday afternoon at Baltimore-Washington International Thurgood Marshall Airport, the first time this year they have reached that milestone.

Highs Wednesday are forecast in the upper 70s. After storms pass through, cooler temperatures and lower humidity are forecast, with lows Wednesday night in the 50s and highs Thursday around 70 degrees, with more rain chances.

Highs Friday and into the weekend are forecast in the upper 70s with dry weather.
