Bye Bye warmth: Cold winds sweeping eastward today

STATE COLLEGE — Cold air pouring in across the Midwest will reach the Appalachians this afternoon and will sweep to the Atlantic coast Friday night.

In the wake of a strong cold front, temperatures have been slashed by 25 to 35 degrees over the Upper Midwest.

While the magnitude of the temperature change will be somewhat less extreme as the front progresses eastward, temperatures will drop by 20 to 25 degrees over the Ohio Valley and 15 to 20 degrees along the Atlantic Seaboard Saturday and Sunday, when compared to highs during the latter part of this week.

Much cooler air will continue to push across the South, reaching South Texas and much of central Florida. Temperatures will be shaved by 10 to 20 degrees in most areas.

The impact of the front will only diminish over South Florida.

The flow of cold air over relatively warm water will cause lake-effect snow, flurries and squalls to spread from northwest to southeast, down wind of the Great Lakes. A couple of snow squalls can reach as far as the central Appalachians with a flurry possible in some of the northern and western suburbs of Washington, D.C., Philadelphia and New York City during Saturday.

While everyone may not be a fan of the chilly, blustery weather, the pattern will stir out the atmospheric conditions that have helped to produce locally dense fog during recent mornings.
