Weather Summary
Jessica Parker
Weather Underground midday recap for Wednesday, May 16, 2012.

Unsettled weather continued in the Eastern U.S. on Wednesday as a long cold front dropped across the Midwest and reached from the Lower Great Lakes through the Southern Plains during the afternoon. Moist and unstable conditions ahead of the northern edge of this cold front led to scattered showers and chances of thunderstorms across the inland Northeast. Storms over parts of New York, Pennsylvania, and western New England had the potential to turn severe this afternoon with large hail and damaging wind gusts. Meanwhile, to the south, scattered thunderstorms popped up again along the sea breeze of the Carolinas. Plenty of moisture streaming across the area heightened instability and led to the possibility of few intense storms with hail and gusty to damaging winds.

Further south, weak winds and a lingering moist airmass allowed showers and thunderstorms to persist across parts of the Florida Peninsula through the afternoon.

In the West, well above average temperatures continued in the Desert Southwest, while a few isolated showers developed in the Central Great Basin.
