Active Pattern Returns through the Weekend

Light snow falling Wednesday night will be done by Thursday morning, but not before producing a dusting up to half an inch.  Warmer temperatures Thursday evening will allow the potential for light freezing drizzle or freezing rain into Friday morning. 

An even stronger storm system will move in from the Plains late Friday night and Saturday.  Aloft there will be enough warm air to warm temperatures above freezing, but near the surface temperatures will hoover right around freezing due to the snow on the ground.  This could lead to freezing rain overnight Friday into early Saturday morning.  By mid-morning Saturday, temperatures should be warm enough throughout the atmosphere to produce mostly rain, and

possibly a lot of it.  Moisture values rise close to an inch in the atmosphere which could lead to rainfall totals of half an inch, up to an inch of rain by Saturday night.  If rainfall totals are that high, the runoff potential could be high with flooding in ditches and backyards, and possible rises on local creeks and rivers.  Rivers, while not in flood stage, are still high from all the heavy rain back in October.

By Sunday cold air wraps in which could cause the precipitation to switch over to a mix before light snow Sunday night.
