Expect Stormy Weather to Continue Into Tuesday

STATE COLLEGE PA – A muggy start to the week is in store for the mid-Atlantic and Northeast as thunderstorms continue drenching the area. AccuWeather forecasters headquartered in State College say the stormy weather will be in no hurry to wind down.

The National Weather Service in Mount Holly NJ has expanded its flash flood watch for the area to include portions of Berks, western Chester, and western Montgomery counties through late Monday (July 12, 2021). A hot and humid air mass will cause one or more rounds of thunderstorms with heavy rain to affect the area from the afternoon into the night. Rainfall amounts could vary, but a general 1-to-3 inches of rain is possible, it predicted.

Through Tuesday, showers and thunderstorms can be expected to continue to drench many of the same areas that experienced downpours and severe weather during the weekend. Several areas – including Harrisburg, where more than 2 inches of rain fell late Sunday (July 11, 2021) – were under flash flooding warnings, AccuWeather said.

Drivers should be alert for rapidly changing road conditions and reduced visibility when traveling through torrential downpours. Experts advise not to drive through any areas of flooding or standing water on roadways, as it can be difficult to gauge how deep the water is and could result in a deadly situation.

Multiple reports arrived early Sunday evening from western and central Pennsylvania of downed trees and power lines amid the severe weather. The website PowerOutage.us reported thousands of homes in Pennsylvania and adjacent states were without power at some part of the day, according to AccuWeather Meteorologist Nicole LoBiondo.

Hot and humid conditions will continue to be ushered into the mid-Atlantic and Northeast thanks to a feature known as the Bermuda High. This will be the fuel for any severe thunderstorms to rumble across the East. “Shower and thunderstorm activity is likely to continue with a chance of daily storms from through at least the middle of the week in much of this area,” AccuWeather Lead Long-Range Meteorologist Paul Pastelok noted.

“Forecasters stress the need to move indoors at the first rumble of thunder. Picnic pavilions, tents, and umbrellas do not offer the protection that is needed from lightning strikes,” AccuWeather Meteorologist Alex Sosnowski warned.
