Storms to bring flooding, damaging winds from Plains to Northeast into this week
Flooding downpours, damaging wind gusts and hail will target parts of the Plains and Northeast into this week as a potent dip in the jet stream moves east.
Severe thunderstorms drenched much of the Northeast on Aug. 20, but parts of Delaware, Pennsylvania and New York were hit especially hard.
An active weather setup across the United States will fuel severe thunderstorms and flooding across portions of the Plains, Midwest, mid-Atlantic and Northeast into this week. This comes just days after a large complex of storms produced tornadoes from Pennsylvania to New Jersey.
Southerly winds will transport abundant Atlantic moisture into the East, fueling flooding downpours. The greatest risk of flooding will be roughly along and east of the Interstate 95 corridor, stretching from New Jersey to southeastern Massachusetts. An elevated flooding risk will also extend into northeastern Ohio and northwestern Pennsylvania.
"Since August has been wet and the soil is already saturated in some areas, additional showers and storms can easily produce run-off into poor drainage areas and lower-lying spots. Heavy rainfall rates can also lead to standing water on some roads," AccuWeather Meteorologist Chad Merrill said.
Severe thunderstorms to target portions of the Rockies, Plains
Following Saturday's severe weather, additional rounds of strong to severe thunderstorms are anticipated across northern portions of the Rockies and Great Plains on Sunday afternoon and evening. Hail and localized damaging wind gusts will be the main hazards, with an AccuWeather Local StormMax™ of 80 mph.
Farther east, the severe weather threat is not expected to be as widespread as Saturday in this region, though stronger thunderstorms could still produce gusty winds and small hail. A few lake-effect rain showers could also develop near the Great Lakes.
Cooler and less humid air will spread south behind the storm system Sunday afternoon and evening. Drier weather will follow across much of the region for the start of the new week.
Severe thunderstorms to once again target Great Plains Monday
Additional rounds of thunderstorms are expected across northern portions of the Great Plains on Monday. Localized damaging wind gusts and hail will be the main hazards. Downpours and strong winds could lead to travel disruptions during the Monday evening commute.
