[UPDATE WEDNESDAY OCTOBER 30, 12:52 P.M.] The National Weather Service says a WINTER WEATHER ADVISORY is in effect starting Wednesday night at 7 p.m. through Thursday afternoon at 1 p.m.] Widespread areas of 2 to 4 inches are expected, with some places seeing as much as a half-foot of snow. The heaviest is expected to be along the Iowa-Illinois border and into the state of Illinois.

[UPDATE WEDNESDAY, OCTOBER 30, 10:51 A.M.]: 1-2" of snow will be likely south of Highway 20 and there could be some 3" amounts, especially in southeastern Iowa. Snow will start this afternoon and continue through tomorrow morning.

[ORIGINAL POST]: CBS2 Weather First confirmed for us that 3.3 inches of snow fell overnight in Cedar Rapids Monday night into Tuesday. The bad news is, we're not done yet.

Wednesday and Thursday bring more accumulating snow, though the track and amounts are still uncertain. "A wintry mix will be possible in the afternoon and then switch to all snow overnight into Thursday. There is uncertainty of how much snow will fall, but the higher chances for accumulation will be south of Highway 20", according to their website.

1-3 inches is currently expected, with tweaks likely. No matter what, we will see more measurable snow in this next system. Grab the shovel (make sure the snow-blower is ready just in case). Bundle up for trick-or-treating and any other outdoor activities because at any rate, we do know it's going to be cold. Temperatures will be in the mid-30s Wednesday. For Thursday, snow will be done by the afternoon, but temperatures by trick-or-treating time will be near 30.
