New, Changing Data On Next Week (Mainly Regarding Timing)February 15th, 2013 at 10:52 pm by Chad Evans under Chad's WLFI Weather Blog
Monday looks like a 1 p.m. to 10 p.m. rainfall period. Looks too warm for any start of sleet & it appears the rain will exit too early for any sort of changeover to snow. Looks like 0.20-0.40″ of rainfall, right now.
Late week system looks to arrive earlier.
It looks as if snow could move in early Thursday afternoon, then change to sleet from southwest to northeast. By 7 p.m., looks like all sleet over most of the viewing area with freezing rain Lafayette & southward. By 10 p.m., it looks like all sleet north of Lafayette & freezing rain south of Lafayette. By 4 a.m. looks like rain over all of the area except in northern Newton, Jasper, Pulaski & Fulton counties. Everyone may go to rain briefly, followed by a period of snow showers sweeping in Friday morning-midday.
All said, at least right now, minor snow accumulations are likely with the potential of decent, but not major ice accumulations. Temperatures look to rise from 26 to 36 then down to 27 during duration of the storm, overall.
Heavy snowfall accumulations of 8-16″ & blizzard conditions are possible Des Moines, Iowa to Madison, Wisconsin to Grand Rapids, Michigan.
We need to keep an eye on the track of this storm, but track so far has been consistent. Currently, confidence is reasonable in projected track & precipitation type here. If there is a shift to the south, our snowfall potential will go up & we need to watch ice accumulations to see if they look to reach a damaging threshold (at least for a while before changing to a period of rain).
