The Storm Prediction Center has indicated that areas from the Lower Hudson Valley in NY south to Delaware, Maryland and Northern Virginia have a marginal to slight risk for severe thunderstorms late this afternoon into tonight. This is thanks to a cold front that is dropping southeast from Eastern Canada, Upstate NY and the Great Lakes. The risk area extends west into the Ohio Valley.

Ahead of this front today will be the hottest temperatures of the week and in some places the hottest temperatures of the month. Most highs in Eastern Pennsylvania to Southern New England will reach the low to middle 90s. Areas to the south in Southern Pennsylvania into Maryland will see highs in the upper 90s to near 100. Meanwhile cooler air in Upstate NY is not that far away. Sunshine will occur for much of the day and then thunderstorms will develop in the late afternoon and evening. Not everyone is going to see thunderstorm activity.

Thunderstorms overnight will shift southward as high pressure builds strongly into New England. An onshore northeast flow develops and that will put an end to the heat. The front is going to drop southward and stall across the Delmarva Peninsula and back westward into Virginia. The onshore flow will remain in place through Friday and then turn southerly Saturday ahead of another cold front that will be moving through over the weekend.
