The polar vortex has again slipped its icy fingers down the warm necks of York County, jarring residents from a tease of warmer weather just in time to dump another foot of snow down their backs.
Yorkers woke up to about 2 degrees Friday morning, and the weekend will end with a storm that could bring about 12 inches of snow through Monday afternoon.
There will be a brief period of "warmer" temperatures Saturday and Sunday, with the mercury reaching as high as 40 on Saturday and the high 30s Sunday, said Craig Evanego, a meteorologist with the National Weather Service in State College.
The snow will start as the polar air makes its way back into the area during the day Sunday, and how much snow will fall depends on exactly when a wintry mix switches over to all snow as temperatures drop, he said.
If the entire storm is snow, accumulation could be more than a foot, he said. But he said it's more likely for York's snowfall total to reach between 10 and 12 inches because some of the storm could be freezing rain or other forms of precipitation.
The average temperature in York County for this time of year is highs in the mid-40s and lows above freezing, Evanego said. This year has been one of the coldest and the snowiest on record.
The winter has bought up a lot of residents' cold-weather patience, and many York stores have long sold out of cold-weather implements and replaced them with optimistic departments of gardening tools and outdoor furniture.
"The winter doesn't want to give up this year," Evanego said.
It is scientific fact that the cold weather will give way to warmer days, he said.
The days are getting longer and the sun's angle is getting higher, he said.
Spring officially starts in 19 days, on Thursday, March 20.
