while periods of rain occurred over the southeast third to half of 
the state. across the northwest, periods of light freezing rain was 
reported. Temperatures ranged from the lower to mid 20s across the

Tuesday. Showers and thunderstorms with heavy rain will occur across
southeast portions of the Upper Midwest while further northwest,
periods of freezing rain or drizzle will be the main impact to the
area depositing up to a quarter inch of ice and making for treacherous
travel and some potential for broken tree limbs and downed power lines
in the heavier ice accumulations.  

A brief break will come on Wednesday before another system impacts
the region on Wednesday night and Thursday bringing another chance for
freezing rain or freezing drizzle and some snow to northern areas.
Then after a brief break Friday, another system will move across the
area Friday night and Saturday. Highs will be on the cool side with
20sand 30s expected although late in the week, some moderation into 
the 30s and 40s will be possible. Lows will be in the single digits
