(Radio Iowa) – Forecasters say another storm system is expected to reach the state later this week that could bring snow across Iowa’s northern half and rain to the south. Meteorologist Cory Martin, at the National Weather Service, says the divider line between snow and rain runs from Council Bluffs to Des Moines to Cedar Rapids to Dubuque, but just a few degrees shift in the temperature could make all the difference.
“Temperatures are going to be warm enough to support actually a fair share of rain probably for a good chunk of the area as the storm system moves in through the day on Thursday,” Martin says. “If we’re looking for any snow, it may be confined to far northern Iowa, whereas further south, right now, we’re looking at warm enough for some rain to fall.” Once the sun sets on Thursday night, Martin says those conditions could change — or not — as the system is still developing. 
“Thursday night into Friday morning, temperatures may cool enough to allow that rain-snow line to sink further south and into central Iowa,” Martin says, “so, still quite a bit of uncertainty there and just how far south we’re going to see snow, just because we’re talking the difference of just a degree or two.” Wide sections of north-central and northeast Iowa may see two or more inches of snow, which could make driving hazardous from Mason City to Decorah.
“It’s certainly possible up there that we’re going to see slick and snow-covered roads that may impact your travel especially as we get into Thursday night,” Martin says. “Once the sun goes down, temperatures cool a little bit more, so that’s definitely something that we’ll be monitoring.” Keep up with the developing forecast at weather-dot-gov.

(Radio Iowa) -Things are going to get pretty windy across the state today (Friday). Jeff Zogg of the National Weather Service says this impacts every county. “There’s a pretty strong cold front that’s going to be moving across the state later on today into this evening. And especially behind that, the winds are going to pick up. We have a wind advisory for the entire state for later this afternoon into this evening,” Zogg says Zogg says there could be some pretty powerful gusts.
“Northwest winds 25 to 35 with gusts of 50 to 55 miles per hour possible,” he says. You might want to be sure everything in your yard is secure. “With those winds, definitely has the possibility to blow around unsecured objects — including holiday decorations if they’re out– and tree limbs could be blown down and there could be some power outages as a result of that,” Zogg says. You can also say goodbye to the warm temperatures.
“This will be the warmest day that we’ll see for a little bit. Highs on Saturday across the state will range from the lower 20s to the middle 30s,” Zogg says. Those driving high-profile vehicles this afternoon and evening should use caution in the high winds.
Today: Partly cloudy & windy. High 55. Winds S/SW winds @ 20-35 mph becoming NW late.

(Radio Iowa) – State climatologist Justin Glisan says November numbers were unremarkable except for a little bump up in precipitation. “A little over two inches for the statewide average — and that’s almost three-tenths of an inch above average. So, the first month of the fall season in which we had above average precipitation for the state,” Glisan says. He says the temperature was right in line with the average.
“Overall if we look at temperatures right at 37 degrees that average temperature, so the daytime high overnight low add them together and divide by two, so right on the button in terms of climatology,” he says. Glisan says the short-term forecast for December is mixed.
“As we move into December and January — the two coldest and driest months of the year — when we look at the outlook for six to ten and eight to 14 days — we do see an elevated signal for colder temperatures and then near normal precipitation, so at least to the first half of the month,” according to Glisan. The longer-term forecast doesn’t signal a lot of snowfall.
“Elevated probabilities of colder and drier conditions for the state. So, that suggests less snowfall. Now we’re still stuck in that La Nina phase which dictates where the storm tracks that’s up over the United States,” Glisan says. “So we are seeing basically a classic line in your signature on the precipitation front and what you see a bullseye of above average precipitation in the Ohio Valley in the Pacific Northwest, but that dry signal is showing up for the state of Iowa.” He says the forecast now for later in the winter shows a shift from LaNina to a more neutral position.
“Right in between La Nina and El Nino as we get into the February, March April timeframe. So we’re seeing a shift in the probability of what are the normal conditions across the eastern half of Iowa, and an equal chance of above below, or near average in western Iowa,” Glisan says. Today marks the beginning of the meteorological winter in the northern hemisphere.
(Atlantic, Iowa – KJAN) – The month of November here in Atlantic was, on average, three degrees warmer than normal as far as the High is concerned, at 49-degrees. Conversely, it was nearly three degrees cooler for the Low, at 24-degrees. Precipitation for the month continued the trend of being much less than what we would typically expect. Liquid precipitation (melted snow/ice & actual rain) in November amounted to just .91″ (91-hundredths of an inch), which was nearly an inch (.94″) less than what we should have had.
Here’s what the the stats for Atlantic normally are, for December:
Today: Mostly sunny. High 46. Winds S @ 15-20.
