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.
