(Radio Iowa) – Don’t plan on putting away the heavy coat anytime soon. National Weather Service Meteorologist Brad Small says the cold temperatures are going to get worse. “There’ll be some snow first. The weekend will start off dry — but snow will move into much of Iowa sometime on Sunday from northwest to southeast, Sunday to Sunday evening,” Small says.
He says they are predicting accumulations of one inch from central Iowa to the south — and then larger amounts moving to the north. “We could see amounts of three to four inches — something of that nature from Fort Doge north and west,” Small says. “A good chunk of the state will see some snow. It won’t be a heavy snow at any particular time — it’ll be light to moderate for an extended period. Still enough to get some snow on the ground — especially on the grass.
There could be some melting during the day, Sunday, however by Sunday night we’ll see snow in most locations.” The cold temperatures will follow. “After the snow ends we’re expecting near-record cold and even some records possible in some spots Monday and Tuesday,” Small says. “The coldest morning is Tuesday morning when we’ll see lows in the teens and single digits from Des Moines north and west, and low 20s towards Ottumwa.”
Small says it’s just a matter of the cold weather pattern being stuck over the state.
Today: Mostly cloudy w/a chance of sprinkles or flurries this morning; Becoming partly cloudy. High 41. NW @ 20-35mph.

(Radio Iowa) – Despite the damp weather we’ve experienced over the past couple of days, open burning bans remain in effect for 18 Iowa counties. State Fire Marshal Dan Wood says that’s not common for this time of year. “Usually it’s less than that, but usually we’ve had more moisture where this year has just been very much a drought statewide,” he says. Burn bans are not issued by the State Fire Marshal’s office. Local fire chiefs and emergency managers in each county determine there’s an elevated fire risk and issue the ban on open burning in a county. The State Fire Marshal’s website lists the burn bans that are in effect.
Most of the 19 counties are in the western half of Iowa. “Having a very dry summer and now a very dry fall we’ve had a lot of counties go with these burn bans,” Wood says, “kind of sounding the alarm for the dangers of their being field fires.” A recent western Iowa field fire was one-and-a-half miles wide at one point. Fire officials advise farmers to have a disc nearby as combines roll through a field. If a fire is sparked, the disc can be used to turn over crop residue and create strips of soil to stop a fire from spreading. On a couple of days this fall, northwest Iowa farmers have been advised to halt the harvest due to high winds that could quickly spread a fire sparked by a combine.
In this area, counties with burn bans still in effect until further notice, include: Audubon, Cass, Harrison, Mills, Montgomery, and Pottawattamie.
