Low pressure will impact the Mid-Atlantic region from later today into the overnight hours with two threats on the table...severe weather and flash flooding. This low-pressure system will push eastward into southern Pennsylvania later today and end up over southern New England by late tonight. An upper-level jet streak will add fuel to the fire in the Mid-Atlantic region with strong upward motion that is destabilizing the atmosphere and thunderstorm coverage is increasing across western sections. Localized flash flooding can result from the “training” of thunderstorm cells meaning multiple storms may move over the same general area producing excessive rainfall amounts.

The work week will start off on the wet side as low pressure heads in this direction from the Midwest. There will be occasional showers from this afternoon into Tuesday and multiple thunderstorms can be mixed into the picture. Some of the rain will be heavy and some of the storms can be severe and there is the threat of localized flooding as thunderstorms can develop in a “training” fashion meaning multiple heavy rain cells could move over the same general area.

An incoming frontal system will keep it unsettled around here today and occasional showers and maybe a thunderstorm…any storm can be on the strong side. In addition to the threat for rain, today will feature warmer, and more humid conditions, and the winds will become quite noticeable gusting from a southwesterly direction past 30 mph or so. The passage of the frontal system later tonight will open the door for some decent June weather for the Mid-Atlantic region in the Friday and Saturday time frame and then clouds should increase on Sunday ahead of a possible rain soaking event on Monday.

After a couple of very comfortable days in the Mid-Atlantic region, changes will take place here at mid-week with warmer and more humid conditions on the way. The atmosphere will also become more unstable later today as an upper-level low expands into the northeastern states bringing us scattered PM showers and thunderstorms. On Thursday, an incoming frontal system will generate more instability in the atmosphere and there can be another round of PM showers and thunderstorms...some of those late day storms on Thursday can be strong-to-severe. From this vantage point, the passage of the late week frontal system looks like it’ll set us up for a pretty decent weekend in the Mid-Atlantic region.
