Widespread life-threatening flash and urban flooding continues in south-central Texas, with considerable flooding impacts possible across central Texas. Wildfire smoke is impacting air quality across much of the Great Lakes region into southern New England and the Mid-Atlantic. Monsoonal thunderstorms may produce isolated to scattered flash flooding across the Southwest into the Great Basin. Read More >
Overview
A line of storms moved into Western Pennsylvania during the afternoon of April 3rd, 2006, and produced large amounts of small hail. A few reports of wind damage in large/damaging hail were received from Warren County (Northwestern PA), but all the rest of the hail was smaller than pennies - which is the threshold for severe/damaging hail.
The unusual thing about these storms is that they made copious amounts of small hail - as it covered the ground in many places in the Laurel Highlands and Allegheny Plateau.
