Severe storms to disrupt Saturday activities in northeastern US

A line of severe thunderstorms will march across the northeastern United States into Saturday night with the potential for flash flooding, damaging wind gusts and isolated tornadoes.

The storms will cut the warm weather for much of this past week.

Winds can be strong enough in some locations to cause minor property damage, knock down weak trees and spark sporadic power outages.

Rain can be heavy enough to quickly inundate poor-drainage areas along streets and highways.

Hail may be large enough to cause cracked windshields or dents in roofs of exposed vehicles.

The biggest impact from the storms will be disruptions to travel and outdoor activities. The combination of wind and torrential rain may render umbrellas ineffective.

As the storms press eastward, motorists can face sudden near-zero visibility and very slick conditions due to the combination of torrential rain and strong wind gusts.

Flight delays are likely as the storms approach and move through airport locations.

"While a thunderstorm is a rare event during February, these storms may bring a fair amount of lightning strikes, in addition to the downpours and gusty winds," according to AccuWeather Meteorologist Bill Deger.

People should keep alert for rapid changing weather conditions and seek shelter indoors when thunder roars.

The storms will march across Virginia, Maryland, Pennsylvania and upstate New York during the afternoon.

Late in the afternoon and early evening on Saturday, the storms will intensify and impact part of the I-95 corridor from Raleigh, North Carolina; to Richmond, Virginia; Washington, D.C.; Baltimore; Philadelphia; Newark, New Jersey; and New York City. During this time, the storms will also roll across the Catskills and the Hudson Valley.

It is these locations that are in line for the worst storms which pose the greatest threat to lives and property.

Across northern Maryland, eastern Pennsylvania and Delaware, storms may become strong enough to produce an isolated tornado or two.

Residents in or the near the path of any tornado Saturday should seek immediate refuge in a storm shelter, basement or interior room to minimize the risk of injury.

The storms will not affect Boston until the middle of the night.

While the storms are likely to lose some intensity Saturday night, there can still be locally heavy rain and gusty winds across New England. When combined with melting snow, the rain can still lead to some incidents of flash flooding.

Much colder but more seasonable temperatures will quickly return in the wake of the storms and will erase temperatures in the 50s, 60s and 70s F.

Static US Weekend

Despite a warm, wet and stormy start to the day in Pittsburgh, temperatures are likely to be near freezing with flurries in time for the NHL Stadium Series game between the Flyers and Penguins at Heinz Field Saturday evening.
