The northwestern Pennsylvania city has already seen 133 inches of snow - more than 11 feet - through January 10, making it the snowiest city (population of 100,000 or more) in the United States so far this winter.
LITTLE ROCK, Ark. - Winter weather is expected Thursday night and into Friday morning for parts of Arkansas. Snowfall accumulations of 1 to 3 inches possible. More accumulating snow is possible on Monday, followed by another push of arctic air.
Predicted mixed precipitation and significant snow accumulation has prompted the National Weather Service to issue a winter storm warning for the north country. "We are not expecting any sort of massive snowstorm or any sort of massive ice storm". So please keep an eye on the forecast if you have travel plans Saturday.
Wild whiplash of winter weather to take place Friday
The cold front dragged Thursday morning's moderate temperatures down quickly to around and below freezing temperatures. This won't be the light and fluffy snow we've had so far this season, there will be some weight to it.
The city likely won't have the ice around long enough for widespread power outages, but some areas will receive around about a quarter of an inch of accumulation - which is when power outages begin to occur.
Counties along the OH and Mississippi Rivers are expected to get a tenth of an inch of ice or less. Here is our best estimate of timing for the morning rush hour, the lunch hour, and the afternoon rush hour, with hazardous conditions expected across the board by late tonight. The pink indicates a freezing rain, sleet, and snow mixture.
Localized gusty winds are possible and could produce blowing and drifting snow and reduced visibility.
The storm may bring major travel disruptions throughout the region. Drivers should be aware that even trace amounts of ice can make the roads very slick, especially after a period of rain that may have washed away road treatments.
