Easter weekend will bring some rain and possibly even a little snow

High pressure overhead Friday afternoon will allow temperatures to rise into the low 50s under mostly sunny skies!  Increasing southerly winds ahead of a cold front Saturday will boost temperatures into the mid and possibly upper 50s during the afternoon before rain moves in Saturday evening and overnight.  A cold front will move into the Midwest Saturday afternoon with rain likely developing between 3pm and 6pm in northwest Illinois and then spreading east through the evening and overnight.  Rainfall amounts will remain on the light side with roughly between a tenth and three tenths of an inch of rain falling by Sunday morning.

Cold air will lag behind the first front Sunday so temperatures with a little afternoon sun could rise back close to 50° for the afternoon.  Winds will increase from the west as another front, an arctic front, moves down the western Great Lakes.  While moisture will remain limited with the second front there may be enough forcing in the atmosphere to allow rain showers to develop after 6pm or 7pm and possibly mix with a few snowflakes by Sunday night as the temperature drops below freezing. 

It will be a chilly start to the first few days of April but temperatures look to moderate back into the upper 40s and low 50s by the end of next week.
