Winter Storm Warning continues in the pink shaded counties through Tuesday evening in the west and early Wednesday morning in the far east. It along with the Winter Weather Advisory has been expanded in the last half hour to include a few more counties in the west central portions of the state. Snow accumulations of 4-9 inches have already occurred in central Iowa with a lot more snow to come. Totals by Tuesday evening will range anywhere from 6-12 inches, given what has already fallen and another 18-30 hours more of snow to come.

Travel is not advised in the Des Moines, Ames, Marshalltown, Newton and Grinnell areas this evening, with many more roads becoming hazardous throughout the evening into tomorrow morning.

Current temperatures have plummeted across the western and central portions of the state where the winds have switched to the NW.
Spencer has dropped to -18 (the validity of that reading is in question), but Sioux City is at -5, Des Moines is at 4, Waterloo at 7, Mason City at 3. Where the winds haven’t switched to the NW, readings include, Cedar Rapids 24, Dubuque at 23, Iowa City 26, Burlington 27, Quad Cities 25 and Keokuk 30.

Temperatures will drop quickly as NW winds take hold across the state tonight, with readings dropping 10-15 degrees in a few hours after the winds switch to the NW.

Snow totals so far will be posted later this evening.
