11:50 AM | Heavy showers and embedded strong thunderstorms closing in at the noon hour

Discussion

The combination of low pressure and a cool front is generating a wide area of showers and embedded strong thunderstorms across West Virginia, much of Maryland and Virginia, and it is headed for the big cities along the I-95 corridor for the afternoon and early evening hours. Some of the rain will fall heavily at times beginning at mid-day across the Philly and DC metro regions and then in the early-to-mid afternoon hours across NYC, and there is likely to be occasional thunder mixed in up and down the I-95 corridor through the afternoon and into the early evening. Given the still saturated grounds throughout the Mid-Atlantic region, flash flooding is still a big concern as the soaking rainfall with torrential downpours moves in. Improvement occurs on Wednesday as Canadian high pressure builds into the Mid-Atlantic from the Great Lakes region and the second half of the week will be quite comfortable before heat and humidity increase noticeably during the upcoming weekend.
