Storms Continue on Wednesday

A jet stream trough continued over the northeast today allowing for more showers and thunderstorms to develop. An upper-level cold pocket of air shifted across the mid-Atlantic today which destabilized the atmosphere and allowed showers and isolated storms to develop. Some of the showers contained brief downpours and gusty winds. With the cold pocket of air aloft, hail was possible with any thunderstorms and was reported in Virginia. A severe thunderstorm developed late afternoon in southeastern Worcester county, MD and northeastern Accomack county VA which covered the ground with hail 5 miles NW of Chincoteague, VA. Pea to nickel size hail was reported. Drier weather will return on Thursday as the trough lifts out of the northeast.

A ridge in the jet stream will then develop over the east late in the week and hold into next week. This shift in the jet stream will allow warmer air to expand across the mid-Atlantic. Strong late April sunshine will allow temperatures to climb into the low to mid 80s inland this weekend into early next week.
