BREAKING: New weather forecasts are showing a roller coaster temperatures ride into Christmas weekend, rising to near 50 degrees actual temperatures in Central Allegany County, NY, early Friday morning before plunging to sub-zero windchills all day Christmas Eve. The Lake Effect Snow Warning, originally scheduled to end early this afternoon for Cattaraugus and Wyoming counties west, has been cancelled.
At the same time, the US National Weather Service Buffalo NY, in combination with the NOAA NWS Weather Prediction Center (WPC) at College Park, Md., are showing increasing chances for a new weather system bringing a warmup and widespread rain Thursday and Thursday night, followed by much colder conditions and a changeover back to snow Friday, combined with potentially strong winds Friday night and Saturday.
The strong winds will provide a significant gap between actual and wind chill temperatures throughout the period.
The WPC video accompanying this story shows the quickly changing dynamics of a frigid Arctic air mass plunging southward from Canada to much of the United States throughout this week and then moving northeast.
Projections as to how cold Christmas Day temperatures might be are expected this afternoon.
