Temperatures Fall, Snow Chances Rise

A clipper system diving out of Canada draped a warm front across the Commonwealth throughout the day on Tuesday, allowing the entire state to rise above freezing for the first time in 18 days. This relative warmth will be short lived, but unlike the first 9 days of the month, there is no more arctic air on the way. A cold front passed through Pennsylvania early Wednesday morning, prompting temperatures to fall slowly across the state.

Behind the cold front, wind speeds have picked up drastically, sustained between 10 and 20 miles per hour gusting as high as 30 miles per hour. Wind speeds will decrease throughout the day as the cold front pushes south into the Mid Atlantic. Up sloping snow showers are possible across Western Pennsylvania, with Winter Weather Advisories in effect for the Laurel Highlands through 3pm this afternoon.

High pressure will dominate our weather pattern through the end of the week, before a potential storm system moves in for the latter half of the weekend into early next week. This system could produce a plow-able snowfall, but still too early to define exact snowfall totals.
