PENNSYLVANIA — Parts of Pennsylvania are at risk for severe thunderstorms Monday afternoon and evening, according to the National Weather Service’s Storm Prediction Center.
The Storm Prediction Center has placed portions of the Mid-Atlantic, including parts of Pennsylvania, under a Slight Risk (Level 2 of 5) for severe weather.
Forecasters say thunderstorms are expected to increase in coverage and intensity during the afternoon, particularly across eastern and central Pennsylvania. The primary threat is expected to be damaging straight-line winds capable of bringing down trees and power lines.
An isolated tornado cannot be ruled out, especially across eastern Pennsylvania where stronger low-level wind shear may develop. However, forecasters say uncertainty remains regarding how unstable the atmosphere will become, which could affect the overall tornado threat.
The severe weather is expected to develop as a strengthening low-level jet and an approaching cold front interact with warm, humid air across the state. Thunderstorms may also develop along outflow boundaries left behind by earlier rounds of rain before moving east through the afternoon and evening.
Residents are encouraged to stay weather-aware Monday and have multiple ways to receive watches and warnings as conditions can change quickly.
