Record heat and sunshine were suddenly replaced by weekend storms, sparking a third day of severe weather threats in the mid-Atlantic and Northeast and a growing threat of flooding near the Appalachians.
A slow-moving front moving east has taken advantage of plenty of moisture, the result of the lingering effects of a record-setting warm and humid air mass in the region over several days this week.
Severe thunderstorms with winds over 50-70 mph swept through the Northeast Friday leaving tens of thousands without power in Massachusetts and New York and generating more than 200 storm reports for the NWS — most reporting downed trees and/or power lines in areas violent. wind blow.
Andover, Massachusetts was hit by severe thunderstorms and city officials reported several major and secondary roads remain closed due to downed trees and power lines. Much of the city remained without power as of midday Saturday.
Although showers and thunderstorms return to the forecast this weekend, the severe threat is not as widespread for Saturday.
NOAA’s Storm Prediction Center does have a Level 2 of 5 risk for severe weather in eastern Pennsylvania — though Philadelphia is outside the zone this time — but that risk covers northwestern New Jersey and a sliver of southern New York.
Due to the threat, a Severe Thunderstorm Watch was issued for Philadelphia, Washington, DC and Baltimore throughout the evening.
Damaging wind gusts of 50-60 mph are again the biggest threat from severe thunderstorms, in addition to frequent bursts of heavy rain and lightning.

A Flood Watch is in effect for the mid-Atlantic
Further south, it wasn’t wind or hail, but torrential downpours that were worrying.
Thunderstorms along and east of the Appalachians could see rainfall rates of 2-4 inches per hour, and repeated groups of storms could cause flash flooding.
Flood Watches are in effect until late Saturday from southern West Virginia, through western Virginia and into western North Carolina, including Roanoke, Virginia and Charlotte, North Carolina.

Sunday doesn’t look like much, if anything drier in the mid-Atlantic or Northeast with showers and thunderstorms expected to continue.
The threat of severe weather is diminishing for Sunday but another quarter to half of rain is likely leading to gray skies and increasing puddles.
