The severe weather threat for Severe Thunderstorm Watch 278
continues.

SUMMARY...Severe threat continues within WW277 and WW278.

across much of PA into northern MD/WV this afternoon. The strongest
cluster to the south has produced winds around 60-75 mph over the
last hour. Radar presentation continues to show 50-60 kt winds in
