FIRST CALL FOR TUESDAY NIGHT INTO WEDNESDAY’S STORM, TIMING & AMOUNTS INCLUDED

As we mentioned yesterday, the Winter Storm threat to the state that will be impacting us late Tuesday into Wednesday, will be a rain maker for most locations. However, Northwest PA and the Laurel Highlands will have a chance at seeing accumulating snowfall.

A low pressure will gather its energy and slowly strengthen over Southern Ohio before tracking through Central PA. Unfortunately, for snow lovers, this puts most of us on the warm side of the low pressure system. As this low pressure heads off toward the Northeast, it will begin to rapidly strengthen and deliver a much more significant snowstorm to our neighbors up North in Northern New England and Canada.

But staying more local to our area, here is how things are shaping out for Tuesday/Wednesday.

Timing: Precip will arrive here between 7 and 10 PM Tuesday Evening in far Western PA and move its way East during the night time. The precip will likely start as rain for even areas in far Northwest PA, but will change-over to an all snow event for NW PA, remainder of us will remain all rain.

AREA A – Precip will begin as rain Tuesday Evening before transitioning to a moderate, to at times, heavy wet snowfall. 3 to 6 inches of snowfall is expected. This area will have to keep an eye out for isolated power outages as the snow will weigh down on power lines and tree limbs.

Area B – The bulk of the moisture will be rain, however, as the low pressure heads Northeast, wraparound snows will fly in this area and will accumulate anywhere from 1 to 3 inches of wet snow.

Area C – This will be an all rain event for these areas. Anywhere from a quarter inch to an inch of rainfall is expected. Flooding should not be an issue.
