A line of showers and thunderstorms is expected to move from northwest to southeast across the area late this afternoon into tonight. Storms are expected to develop around 4-5pm across far northwest Iowa. Storms will move rapidly to the southeast with the peak impacts between 6pm and 11pm. Damaging winds, large hail and frequent lightning are the primary concerns. A tornado or two is also possible, although the higher tornado risk has shifted north into Minnesota. While a brief period of heavy rainfall is possible as the storms move through, the faster movement of storms should limit the flash flood threat. The greatest threat for severe weather is over the northern third of Iowa, with areas from Atlantic to Council Bluffs northward, to Carroll and east to Ames under a slight risk.

(Radio Iowa) — This is the last week of summer and forecasters at the National Climate Center are raising the odds of an El Nino weather pattern impacting our region soon. Meteorologist Dennis Todey, director of the U-S-D-A’s Midwest Climate Hub in Ames, says we may see a shift within a few months. “We get into El Nino conditions maybe by late fall but probably by mid-winter,” Todey says. “The probability is around 65 to 70% chance right now.”
Forecasting models indicate a weak El Nino is most likely, Todey says, but that’s just at the moment. “This one will probably not be a particularly strong one,” he says, “so, therefore, what we expect out of this, we can’t assume as much out of it this time. Typically, we talk about El Nino winters as higher likelihood of being warmer than average throughout most of the Northern Plains, the northern Midwest. That’s still the thinking.”
Todey says it’s a safer bet the impacts of the weather pattern will be felt more next year than this fall. “The other thing, when we have El Ninos, we expect a better chance of precipitation as you get into springtime,” Todey says. “The indications for fall aren’t as strong and we’re really not being impacted by El Nino right now, so, we can’t say too much about the fall as being too much different from average right now.”
Forecasts for the last three months of the year show near-normal temperatures and precipitation are likely for the region.

Strong storms that moved into western Iowa Tuesday afternoon, brought hail, winds of up to 60 miles per hour, and caused scattered power outages. According to the National Weather Service, a thunderstorm wind gust of up to 60-mph at around 3-p.m. was recorded by an Iowa DOT system, and hail a bit larger than the size of peas was observed. The event occurred about two-miles south/southeast of Adair.
Four-miles north/northeast of Anita, about 10-minutes earlier, a DOT automated site recorded a 60-mile per hour gust of wind. Power lines and/or poles were reported down in Kimballton Tuesday afternoon, as well, after storms pushed their way through Shelby and Audubon Counties.
There were no other, immediate reports of damage or injuries.
