Before we get into the details about Tuesday Evening into Wednesday, a disturbance is still projected to move through the state Tonight and into Tomorrow Morning bringing with it a mix of rain and snow. Our call from last night still stands with this system. If you missed our call, click here>>>https://paweatheraction.com/light-snow-sunday-night-wintry-mix-arrives-mid-week

As for the bigger storm potential, we are tracking a Winter Storm set to begin Tuesday Evening and lasting through Wednesday Morning. A low pressure system will develop in the South and track its way Northward before transferring its energy into a coastal low. Over the last 36-48 hours, guidance has been steadily trending colder and colder for this system. While this still won’t be an all snow event for most of us, this will lead to a longer duration of snow versus rain for many locations.

For a visual on this, below is the Canadian Model valid 7 PM Tuesday Evening.

The further North you are in PA and the higher your elevation is will increase your chances of receiving accumulating snowfall. Many low elevated valleys will receive a slushy mix or just a cold rain.

It is projected as this storm wraps up and the precipitation weakens, most locations end in the form of light rain.

Timing: Tuesday Evening into Wednesday Morning

MAP FORECAST FOR WINTER STORM TUESDAY INTO WEDNESDAY

Area A: 4 to 6 inches of heavy wet snow is possible, ending as a brief period of drizzle. Isolated power outages would be possible in these areas as the snow would weigh on power lines and tree limbs. 

Area B: 2 to 4 inches of wet snow is possible, ending as a period of light rain. 

Area C: 1 to 2 inches of wet snow is possible before changing to a period of rain. 

Area D: Up to 1 inch of wet snow is possible before changing to rain.

Area E: Up to a coating of wet snow is possible before changing to rain.

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!
