Temperatures Moderate on Christmas Week

A weak disturbance has increased clouds this evening.  It will be mostly cloudy overnight along with a chance of flurries. It will be partly sunny on Sunday with increasing clouds in the afternoon. and continued cold with a high around 20.  A stronger disturbance will affect the area early in the week with a chance of accumulating snow by Monday night.  Snow will linger into Tuesday before the system moves off to the east.   On Wednesday high pressure will take control, but skies will be slow to clear out.  On Thursday the high pressure ridge will move off to the east allowing the next system from the west to approach the midwest.  With a zonal flow in place for most of the week,  temperatures will top out close to average. There will be a chance of snow by late Thursday continuing though Friday afternoon assuring the Stateline of a white Christmas.  Canadian high pressure will take over again on Christmas making for a cold holiday with some sunshine.
