Monday will feature the most widespread Severe Thunderstorm threat of the season, in regards to how much of the State is in the SLIGHT RISK category as oppose to MARGINAL.

Severe Thunderstorms will fire up along a front that will be passing through the State Tomorrow. The line of storms may not be a solid line, more like a broken line of storms, however, anywhere along the front, there is the chance for a Severe Storm to develop.

Hires Nam future radar shows this well: Valid 4 PM Mondayhresnam 4 pm

Notice how it is not a solid line, but it extends all the way from Southwest PA to Northeast PA, putting all locations in between under a risk for Severe Weather.

Timing: Northwest PA will be the first to be impacted in the late Morning hours Monday, then the line will move from Northwest to Southeast as we head into the Afternoon hours. All activity should be shut off by 8 PM.

Main Impacts: SPC states that the storms that do develop Tomorrow will pack a punch in the form of Damaging Winds.

Area A – The Storm Prediction Center has placed much of PA in a SLIGHT RISK for Severe Weather. Again the main impact will be damaging winds, but of course heavy rain and frequent lightning will also occur.

Area B – This includes extreme Southeast PA, the SPC has placed this area under a MARGINAL RISK for Severe Weather.

If you have any outdoor plans Tomorrow, I would not cancel them, but definitely keep your eye to the radar and follow our Facebook Page for updates throughout the day>>>>PA Weather Action on Facebook!

Josh has been passionate about weather as long as his memory dates! From watching the Weather Channel at age 7, to making hand-drawn hurricane maps at age 11, starting his first weather site at 13, and founding PWA at 15 and forecasting for the state for the past 9 years, Josh's interest in weather has never dwindled! As difficult as it is, he greatly enjoys forecasting for Pennsylvania due to its countless microclimates. The state is an East Coast severe weather hotspot and nearly always home to the rain/snow line during winter storms!
