A Little Freezing Rain to Rain

As moisture develops and moves in from the southwest, a brief period of freezing rain is possible on Sunday morning.  In fact, scattered pockets of light freezing rain mixed with sleet will move into the area as early as midnight.  A Freezing Rain Advisory takes effect in Green, Rock & Walworth County in Wisconsin at 6am and lasts through 12noon. 

Generally, little to no ice accumulation is anticipated.  Even the advisory areas in southern Wisconsin can expect less than 0.1″ of ice.  Along the I-88 corridor in northern Illinois, the threat for frozen precipitation will come to an end first, as temperatures warm above freezing around the 7am hour.  In the Rockford area and locations along the US 20 corridor, temperatures should rise above freezing around the 8am hour.  Following suit, southern Wisconsin will rise above freezing around the 9am hour.

Once temperatures rise, our attention turns to just plain rain.  Our FutureTrack Rainfall model is cranking out around 0.50″ of rain through Sunday evening.  However, since rainfall will be scattered in nature and intensity, 0.25″-0.50″ is the rainfall range for our local area.  This very dynamic system even includes the chance for a rumble or two of thunder!

By Sunday evening, our chance for rain decreases quickly.  Widely scattered rain showers mixed with a few wet snowflakes are possible after midnight.
