Active AlertsDuncansville, PA

A reinforcing shot of cold air moving in this morning will help to generate a line of heavier snow showers and possibly some embedded, dangerous snow squalls. Visibility restrictions to a half-mile or less, a quick coating of snow on roadways, and brief wind gusts of 30 to 40 mph are expected to accompany many of these heavier snow showers. Depending on exact air and road surface temperatures, as well as the longevity of the snow, flash freeze conditions might develop (a quick transition from wet to icy road surfaces). If this combination of factors (poor visibility, gusty winds, and flash freeze conditions) do develop at one time, then a Snow Squall Warning would be issued for the affected area. A line of heavier snow showers and possible snow squalls is expected to affect the following locations at approximately the reference times: Warren and Tidioute from about 8 to 9 am Bradford, Ridgway, St. Mary's, Dubois, Johnstown, and Seven Springs from about 9 to 10 am Coudersport, Emporium, Clearfield, Altoona, and Bedford from about 10 to 11 am Renovo, State College, Huntingdon, and Breezewood from about 11 am to 12 noon Use extra caution if you must travel into a snow squall, slow down and consider exiting the highway. Rapid changes in visibility and potentially slick roads may lead to accidents. Please use extreme caution and allow plenty of stopping distance. Avoid braking suddenly.

What: West winds 20 to 30 mph with gusts up to 55 mph expected.
Where: Bedford, Blair, Cambria, and Somerset Counties.
When: Until 1 AM EST Monday.
Impacts: Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result.
Additional Details: The highest winds will be on the ridge tops. Snow showers will also be occurring while the wind is strong. That will mean blowing snow and lowered visibilities at times.

Use extra caution when driving, especially if operating a high profile vehicle. Secure outdoor objects.
