We received .3” snow yesterday, and about .1′ ice. The precipitation melted down to a equivalent of one-tenth of an inch of rain. Our high early in the day was 39. The this morning 22. Last year on this date our High was 43 and the Low was 15. The all-time record High in Atlantic on this date was 65 in 1933, and the Low was -27 in 1989.

…Freezing Drizzle To Impact Evening Commute… .

Areas of freezing drizzle will persist over portions of west central to central Iowa into the evening hours. While the precipitation has mainly transitioned over to snow along and north of Highway 20, areas further south along the Highway 30 and Interstate 80 corridors are seeing a wintry mix of freezing drizzle and ice pellets. Some light ice glaze has been reported, mainly on elevated surfaces and untreated roads across portions of central and west central Iowa. An additional light glaze is likely through the evening hours, especially during the evening rush hour. Further north, snowfall amounts of 1 to 2 inches are possible by tonight.

The Winter Weather previously issued for several area counties has been expanded to include Guthrie-Dallas-Cass-and Adair Counties, and remains in effect until 9-p.m.

A mix of freezing drizzle and ice pellets is occurring and will persist into the evening evening hours. This will include the evening commute. Ice accumulations of up to one tenth of an inch will be possible.

Today (Thursday) is the first official day of winter and it’s beginning to feel like it across Iowa. National Weather Service Meteorologist Brad Fillbach says much of Iowa’s mid-section could receive light freezing rain, while far northern Iowa should see snow. “As far as tonight and tomorrow morning, you’re looking at more freezing precipitation into this evening. Tomorrow looks to be dry with temperatures getting colder,” Fillbach said.

Some slick roads are possible, especially on overpasses and bridges. The snow over northern Iowa likely won’t amount to much. “The snowfall amounts should be on the light side, an inch or less,” Fillbach said. “The heavier stuff will stay up north of Iowa.” Sections of southern Minnesota could get up to three inches of snow today. People traveling through Iowa this weekend could face another hazard. “Weather-wise, the biggest concern for Christmas travel is going to be the temperatures,” Fillbach said. “Temperatures are going to be considerably cooler, with lows in the single digits.”

High temperatures in Iowa Saturday and Sunday will be in the 20s to low 30s. The forecast for Christmas day (Monday) includes a chance of light snow with morning lows near zero in northern Iowa to the mid-teens south. Afternoon highs should range from 10 to 30 degrees.

Winter may be making a very timely arrival later this week. The winter solstice will occur at 10:28 A-M Central Time on Thursday and forecasters say Iowa may see snow fly about that same time as much colder weather arrives, as if on cue. Meteorologist Cory Martin, at the National Weather Service, says they’re tracking a storm system that will be moving across the Northern Plains in the Thursday-Friday timeframe.

“It looks likely that parts of Iowa are going to see their first accumulating snowfall of the winter season,” Martin says. “That looks most likely across northern Iowa at this point. Further south, into central and southern Iowa, it’s a little bit more uncertain. We’re going to have some relatively warm air lingering around that might keep us with rain or a rain-snow mix.”

Since it’s still a few days away, forecasters are shying away from predicting just how much snow will fall and where, though Martin says it’s likely most of central and southern Iowa will see little-to-no accumulation. “Further north, how much snow we’re expecting right now, it doesn’t look like anything too heavy,” Martin says. “It looks like the best bet for heavier snow will probably stay up in South Dakota to Minnesota but we’ll continue to monitor that.”

With the Christmas holiday coming up, there will be plenty of motorists on the roads later this week. Martin says the state’s main east-west corridor may be wet but it shouldn’t be white. “Oh, for Interstate 80, I wouldn’t alter any travel plans at this point,” Martin says. “Just stay vigilant for forecast updates to see if anything changes through the week. One thing to keep in mind for the weekend, we are looking at a rather cold air mass surging south out of Canada. It’s going to be below- to well-below-normal temperatures here. If you’re traveling, make sure you have safety kits with you, just in case something were to happen.”

The latest forecast calls for rain likely most of Thursday before changing to freezing rain near sunset. A mix of freezing rain and snow is likely to continue Thursday night into early Friday morning.  Another travel hazard on Thursday and Friday could be strong, gusty winds. Temperatures will be plummeting over the weekend as well.
