(Radio Iowa) – Some trick-or-treaters in Iowa -could- be crunching through new-fallen snow this Halloween, though the forecast is still a bit shaky for the weekend. Meteorologist Kristy Carter, at the National Weather Service, says some Iowa cities set record high temperatures just yesterday (Tuesday) in the low 80s, but a big cool-down will likely be arriving on Friday. “We’ll be looking at high temperatures in the 30s to 40s on Saturday and Sunday,” Carter says. “There are some precipitation chances this weekend as well, which could come in the form of the dreaded snow word.”
She says there’s at least a chance of falling flakes this weekend across much of Iowa’s northern half as a storm front arrives. “That would be Saturday night into Sunday at this point,” Carter says. “It’d be over northern areas but details are a little bit more uncertain at this point. We don’t have any amounts or anything. It’s just something we’re watching.” Winter doesn’t officially arrive until December 21st, a little under two months from now, but Carter says snowfall isn’t out of the question in October. “The normal amounts for roughly this time of year is actually point-one (inches) for say Des Moines,” Carter says, “so it’s certainly not uncommon to see a trace or so, a very light amount of snow this time of year.”
The long-range forecast says the cold weather is expected to stick around into early next week, before the next chance at a warm-up.
(Radio Iowa) – Iowa could be in store for a warmer-than-normal winter ahead, according to the long-range forecast from the Climate Prediction Center. State climatologist Justin Glisan says the report calls for a warming trend for the upper Midwest during the climatological winter, which runs from December 1st through February 29th. “This goes hand in hand with being in a moderate-to-strong El Nino,” Glisan says. “Typically, El Nino winters are warmer than average and that can have an impact on the type of precipitation we get.” A warmer winter might make you think we’d have less snow, but he says that’s not always the case.
“If we look at snowfall patterns going back to 1950, with moderate-to-strong El Ninos, we typically see less snow but that doesn’t necessarily mean that we see less precipitation,” Glisan says, “however, if we look at the Climate Prediction Center’s precipitation outlook, no clear signal there.” Glisan says precipitation in Iowa varied from past winter seasons.
“If we look at the last few El Nino winters that we have had, 2010, 2016 and 2019, we’ve kind of been all over the board in terms of precipitation,” he says. “2010 was the 45th wettest, 2016 was the 31st wettest, but then you go to 2019, very wet conditions and the third wettest on record.” While the report predicts the winter ahead may be warmer for Iowa and the region, it shows above-average precipitation for much of the southeastern U-S, and below average precip across parts of the north.

(Radio Iowa) – There’s still hope that the remainder of the fall will bring heavier moisture than normal that can help cut back the ongoing drought in Iowa. D-N-R hydrologist Tim Hall says recent rains weren’t enough to make a big dent, but did erase the areas of D-4 or extreme drought. “Areas of Benton and Tama County that were previously in the D-4classification saw enough rain to improve to D-3. But improvement to D-3 is still D-3,” he says. The D-3 designation is extreme drought compared to the D-4 exceptional drought designation. There is only a small sliver of the state that has no drought. Hall says late fall has not been the best time to make up a moisture deficit, though there have been exceptions.
” By the time we get to November, we see less than two inches of rain over the entire month. However, a couple years ago, we saw a very wet October, we’ve seen very wet fall months before,” Hall says. “So there’s certainly the opportunity to see noticeable and really helpful rainfall.” He says warmer temperatures would help, as they keep the ground from freezing and shutting out water. “The first thing that happens when it rains is you get water into the soil matrix and you improve soil moisture. And after that, the water can move down into shallow groundwater. That all sort of comes to an end with the ground freeze up. You tend to get very rapid runoff in ground freeze up and not as much benefit,” Hall says.
The short term forecast has the potential for some rains in the coming week.”There could be widespread rain in the one to two inch rain across a lot of the state. So there’s there’s some optimism that between now and the end of the month we could see another inch plus of rain which would certainly be great,” he says. ” I mean at now, anything we get over about three quarters of an inch in a week is above normal. So we’d love to see that.”
Hall says any rain we get before the ground freezes is a bonus in helping build up of the groundwater that has been way behind for months.
