A winter weather advisory has been issued for the area and the National Weather Service (NOAA) in the Quad Cities is predicting moderate to heavy snow fall tonight into Friday.
According to the NOAA website, a band of snow is expected to develop and spread into parts of eastern Iowa and far northwestern Illinois by late this afternoon. The snow will become heavy at times tonight, with periods of snow then continuing through the day on Friday. Currently the axis of heaviest snow is expected to occur generally along and north of Iowa City, to Davenport, andto a Princeton Illinois line where a Winter Storm Warning has been issued. Advisory amount snow accumulations are expected south of this axis from Sigourney, to Aledo Illinois. Expect a difficult Friday morning commute, especially in the warning areas. The snow is expected to taper off from west to east by late Friday afternoon.
Total snow accumulations of 2 to 5 inches are expected in Iowa, Keokuk, Washington and Louisa counties and in Mercer County Illinois from 6 p.m. to 6 p.m. Thursday.
Motorists should plan on slippery road conditions, including during the morning commute on Friday, and be prepared for reduced visibilities at times.
A Winter Weather Advisory for snow means periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities, and use caution while driving.
Light snow will continue across portions of the outlook area early this morning with snow accumulations of less than a half an inch. More snow, mainly on the light side will move across areas north of Interstate 80 this afternoon into early evening with an inch or
less of accumulation possible. The heavier snow will then develop after dark during the evening from west to east, again along and north of the Interstate 80 corridor. Three to six inches of snow is expected to fall by Friday morning generally along and north of a line from Iowa City, to Quad Cities, and to Princeton Illinois. Amounts will taper off quickly to the south. The snow will then continue on Friday and spread south some as the day progresses. By the time the snow decreases from west to east by late afternoon, at least four to eight inches of snow accumulation is expected generally along and north of Interstate 80. A Winter Storm Warning has been issued for these areas tonight and Friday. Areas just to the south from Sigourney, to Wapello and Aledo Illinois will get two to five inches of snowfall late tonight and Friday, and a Winter Weather Advisory is in effect for these areas. North to northeast winds of 10 to 15 mph will produce at least some minor drifting of snow on Friday in areas that receive several inches of accumulation.
More periodic rounds of accumulating snow are likely from late Friday night through Saturday night, as a few mid level disturbances move across the region. Several inches of additional snow accumulation are possible during this stretch. At the moment, the favored area for higher amounts of accumulating snow is south of Interstate 80.
