Thursday’s High in Atlantic was 85. Our 24-hour Low thru 7-a.m. today was 51. Last year on this date, our High in Atlantic was 78 and the low was 58. The All-time Record High in Atlantic on this date was 104 in 1938. The Record Low was 45 in 1938, 1951 & 1995.
Thursday was the last day of June. It also marked the end of the peak season for tornadoes in Iowa. National Weather Service meteorologist Craig Cogil says the state’s only had about a dozen confirmed tornadoes this year, way below the average of 35 by the end of June. Cogil says it’s been a relatively quiet year so far. “In general, we haven’t seen a lot of stormy activity across the state,” Cogil says. “We’ve seen low numbers with hail and wind damage as well. It’s just not been a really active storm season for the state.”
After a lot of hotter-than-normal days during June, Cogil predicts something of a cool-down to start off July, along with maintaining the generally quiet weather year. “We’ll still see storms on and off but nothing real widespread and temperatures certainly look to be at least at normal,” he says. “I’m certain as we head out, we’ll have a few periods of warmer than normal.”
A National Weather Service survey team has confirmed one tornado impacted parts of Harrison and Pottawattamie Counties, Wednesday evening. The twister, rated as an EF-zero on the Fujita scale, packed peak wind gusts of up to 85 mph. On the ground it traveled 4 1/2 miles, damaging crops and trees in an area stretching from around Interstate 680 a little more than 7 miles southwest of Persia, and ended slightly over 5 1/4 miles west of Neola. No structure damage was observed by the Storm Survey Team.
And, while the peak season is wrapping up, Cogil reminds tornadoes can strike any month of the year and we may still get several. “On average, about another 20 or at least 15 to 20,” he says. “It’s the end of the peak season but certainly still a threat of seeing additional (tornadoes) through the end of the year.” On Veterans Day last November, there was an outbreak of tornadoes with 10 twisters being reported in Iowa.

The National Weather Service sent a team into southwest Iowa this morning (Thursday) to look for any damage to trees, crops and buildings from last night’s two possible tornadoes. Meteorologist Van DeWald, in the weather service’s Omaha office, says the severe weather rumbled through both Harrison and Pottawattamie counties.
“We had a pretty strong storm that developed near Persia, Iowa, and then moved southwest toward Underwood,” DeWald says. “We do have reports of a couple of tornado touchdowns. We are sending out a survey crew to look at that to see if it’s one tornado or two and to find the beginning and ending points.” Persia and Underwood are about 16 miles apart and he says the area was pelted with large hail during the storm which struck about 6 P-M.
“I don’t believe there’s any injuries and there is some damage out there but it seems to be mostly to trees,” DeWald says. “I haven’t heard of a lot of structural damage at this time.” Iowans will need to keep an eye to the sky as more severe weather is possible within a matter of several hours.
“We do have a cold front coming down into the area,” DeWald says. “That could trigger some thunderstorms throughout the day today. Some of them could be strong, especially this afternoon into early evening.”
Some relatively cool conditions have settled over Iowa to end the month of June, similar to the way the month started. But, State Climatologist Harry Hillaker says it was extremely hot nearly every other day. “Overall, it’ll probably end up being just a little bit shy of being four degrees warmer than a typical June, which may not sound like a lot, but we’d probably have to go back to 1988 to find a June that averaged warmer than this one did,” Hillaker says.
The average High in Atlantic thru the 29th, was 87.4-degrees, which was 4.7-degrees warmer than normal. Statewide, the average temperature for June will wind up being close to 74 degrees, also about 4 degrees warmer than normal.
Statewide, the average temperature for June will wind up being close to 74 degrees. Hillaker expects this will likely be the 11th-hottest June in Iowa in 144 years of records. In Des Moines, temperatures reached the 90s on 13 of June’s 30 days. “We had only one location in the state that managed to get to triple digits during June and that was the town of Little Sioux, between Council Bluffs and Sioux City on the Nebraska border. They hit an even 100 degrees on June 11,” Hillaker says.
The average low for the month of June in Atlantic (through June 29th, was 61.5-degrees, which is 2.7-degrees warmer than normal. Rainfall amounts over the month varied widely, with the heaviest totals in northeast Iowa.
“Some areas up there had well above normal precipitation for the month. A few places are over 10 inches of rainfall for June, which would be roughly about double the usual amount,” Hillaker says. Other areas of the state received very little rain in June. “The west-central and southeast corners of the state saw less than an inch of rain for the full month,” Hillaker says. “June is usually the most reliable month of the year for rainfall, so to get less than an inch is quite unusual,” Hillaker said.
In Atlantic, thru June 29th, we received just eight-tenths of an inch of rain. Normally, we would have received 4.98-inches. The U.S. Drought Monitor indicates “moderate drought conditions” exist over southeast Iowa and most of southern Iowa is abnormally dry.

(Updated) — Heavy rain falling over parts of northwest and western Iowa overnight into early this (Thursday) morning, prompted the National Weather Service to issue a flash flood warning for Woodbury County. That warning has since expired. The service said early today (Thursday), that up to 3 inches of rain already had fallen and that thunderstorms in the area were expected to drop heavy rain.
Severe thunderstorms moved through much of western Iowa Wednesday evening, spawning at least one confirmed tornado. The service says the twister touched down near Persia, in Harrison County. Another tornado was observed not far from the Tri-Center High School, in Neola. No structural damage or injuries have been reported, however, hail ranging in size from nickels to quarters, and strong, straight-line winds flattened some corn and soybean field north of Neola, where they received more than an inch of rain.
And, hail up to the size of golf balls was reported three miles southwest of Underwood.
