(Radio Iowa) — State climatologist Justin Glisan says the month of August brought much-needed rain across the state. He says we were an inch below average for rainfall in July and as August winds down, we are about six inches about normal. Glisan says that’s good for the state — especially in the southern areas that have been in drought conditions for some time. In Atlantic, we received 8.85-inches of rain in August, which was nearly five-inches greater than normal. The temperature in August state-wide ended up around one-half degree above normal — though the highs and lows were not what we usually see in the eighth month. “We typically expect 83 degrees for the high and 61 degrees for the low. Well, this month we’ve been above average for the high temperature at around 91 degrees. But the average low has been 51 degrees,” Glisan says. “So, when you take the average of the two, we are near normal.”
In Atlantic, our average High was slightly more than one-degree above normal, at 84.3-degrees. The average Low was a tad bit cooler than the norm. The rain we did get across Iowa came in large amounts and Fort Dodge got more than 15 inches of rain overall in August. Glisan says the rainfall should be more gentle in September. “We’re starting to get more frontal systems moving across the state. And these are the type of systems that bring gentler steady rains for a few hours, and it blankets the state” according to Glisan. “And that’s when we are typically building up water for the next year.”
He says the forecast models are showing a mix of temperatures and rainfall through September and into November. He says there will be above average temperatures, but equal chances for above or below average temperatures. Glisan says they are seeing a good chance for an El Nino pattern to develop, which would make it a warmer than normal winter.

Severe storms that rolled through southwest into central Iowa early this (Friday) morning, dropped one-inch diameter hail at around 4:15-a.m., in Bedford. The National Weather Service says 1.2-inches of rain also fell in a span of about 30-minutes. Severe thunderstorm warning were issued for the area, and for parts of Adair, Madison, Dallas and Guthrie Counties just before 5-a.m., and were capable of producing 60-mph winds and quarter-size hail, but there were no immediate reports of hail or damage.
Strong to possibly severe storms will be possible at times through the day, with chances increasing this evening into the late night hours. Large hail and damaging wind are the main threats along with locally heavy rainfall. A tornado chance cannot be ruled out later today. Periodic storm chances continue Saturday through next Thursday. There is a chance for strong to possibly severe storms today through Sunday night. Large hail and damaging winds will be the main threats. Localized heavy rainfall will be possible with all of the storm chances. River flooding and flash flood threats could increase into next week with several rounds of possibly heavy rainfall expected through the weekend into next week.
