Despite the warmer temperatures Wednesday, State Climatologist Harry Hillaker says August could break up a 10-month long streak in Iowa. Temperatures in August have averaged roughly two-and-a-half degrees cooler than normal. “Chances are fairly good we’ll end the month with below average temperatures, despite warmer weather off and on the next week or two,” Hillaker said. The cooler-than-normal trend in August is a drastic change from July – which entered the record books as the fourth warmest month, on average, in Iowa history. “We haven’t had a month averaging below normal dating all the way back to September 2011 and many of those months were quite a bit above normal” Hillaker said. “This has been quite a change from what we’ve been seeing.”
In July, the capital city of Des Moines recorded 10 days with a high temperature of at least 100 degrees. In August, there have been five days where multiple cities have posted record low temperatures. “Part of that is related to the fact that it’s just so darn dry,” Hillaker said. “We have very low humidity, which allows air to cool off much more at night than it would otherwise and that makes it easier to get unusually low temperatures.”
Iowa has posted nine consecutive weeks with below normal precipitation. There have been some unusual single day temperature swings in August as well. For example, on Tuesday, Hillaker said Mason City hit a low of 41 in the morning before warming up to 81 in the afternoon. Here in Atlantic, our 24-hour low Wednesday was 52. The thermometer darted up to 95 during the afternoon. That was just 5-degrees shy of tying the record High for August 22nd.

The Shelby County Emergency Management Agency is telling residents of the county that outdoor burning will not be permitted AT ALL, today. The County is one of several in far western Iowa to be placed under a “Red Flag Warning” for this afternoon and this evening. The warning is in effect from Noon until 7-p.m. Emergency Management Coordinator Bob Seivert said all Fire Danger indicators will be in the “Extreme” category this afternoon, because any fires that do develop, can move rapidly. He say the amount of “fuel” in the fields and the dry conditions indicate that if fires do develop, they could move into communities, much like they have in the western states of Colorado, Nebraska, and to our south, in Oklahoma.
The county has been in the “High” Fire Danger category for several weeks now, and Sievert says citizens have been very mindful of the dangers and cooperative. He says his agency has had a lot of cooperation from the public in calling in their need to burn, and connecting them with their local fire chief so they can conduct a burn safely. Seivert encourages people who want to burn – not today, as no burning is allowed – in the future, to call 755-2124 so that officials can ensure the burn is safe and conducted according to standards.
Seivert says officials in Shelby County began preparing for today’s Extreme Fire Danger threat, Tuesday night. He says meeting have taken place with the fire chiefs and fire officers in Shelby and surrounding Counties, as well as elected officials. The parameters that exist today and how they differ from other fire emergencies were outlined during those sessions. Seivert warns of what could happen if a fire does develop during the extremely dry, and windy conditions that are expected today. He says they may be asking citizens to leave their homes and move to a safer location, to get them out of harms way.”
Cass County is not included in a Red Flag warning. Instead we are in an “Enhanced Fire Danger” category. Cass County Emergency Manager Mike Kennon told the Board of Supervisors during their meeting this morning, that citizens here need to be wary of the danger faced by fast growing fires, as well. He says you should refrain from outdoor burning, and issued a reminder the County is and has been under a Burn Ban for quite some time. Kennon says Montgomery County Emergency Management Coordinator Brian Hamman is using a Wildland Fire Dispatch procedures. That means if there’s a grass fire, neighboring fire stations will be dispatched for mutual aid. That includes those from communities in the southern part of Cass County.
