There’s an up side to all of the hot and steamy weather — far fewer tornadoes. Jeff Johnson, the warning coordination meteorologist for National Weather Service office in Johnston, says June is usually one of the worst months for twisters in Iowa. That wasn’t the case this year. ”We really are below normal,” Johnson says. “We haven’t had any so far in the state. That’s unofficial. There could be one out there I’m not aware of but very few tornadoes in June which is our peak month, climatologically speaking. June is when we account for a large percentage of our tornadoes. May and June account for about 70% of our annual total.”
He says Iowa’s seen very few tornadoes in 2012, so far. ”Our service area in Des Moines, which is 51 central Iowa counties, I think we’ve had a total of four tornadoes this year, which is really small,” he says. “We had the EF2 that hit Creston on April 14th and that’s been our most significant event but otherwise, very few tornadoes in Iowa this year.” During 2011, Iowa recorded 50 tornadoes which caused 16 injuries and no deaths. Over the past three decades, Iowa has averaged 47 twisters per year.

DES MOINES, Iowa (AP) — Strong storms produced hail, rain and strong winds and causing power outages as they rolled across Iowa Friday afternoon and evening. The National Weather Service says the storms hit central Iowa Friday afternoon with one-inch diameter hail reported in DeSoto along with 50-mph winds, just after 3-p.m., hail up to 2 1/2-inches in diameter in Newton, and winds of 72 mph near Grinnell, where a semitrailer had jackknifed on Interstate 80. Officials say winds toppled a barn near Searsboro. There are no reports of injuries.
Power outages were reported in Des Moines, where 2,200 customers of MidAmerican Energy were without power Friday afternoon. The storms moved into eastern Iowa, where Alliant Energy reported over 19,000 customers without power in Benton, Iowa and Linn counties. Officials say power lines blowing down and trees falling on lines are to blame for most of the problems.

The latest Drought Monitor Report from the Iowa Department of Natural Resources indicates most of Iowa continues to be very dry, but far western Iowa is less affected than the rest of State. Officials say although 78 percent of Iowa remains in some form of dry conditions, a significant increase in areas rated as moderately dry, from 13 percent to 37 percent, has occurred up and down central Iowa.
Rainfall averaged 2.02 inches compared to normal precipitation of the period at 2.36 inches; however, precipitation varied widely across the state, with above normal rainfall over much of west central and southwest Iowa and well below normal over northeast and extreme northwest Iowa. An area stretching from the eastern half of Crawford County southeast through Audubon, the northeast half of Cass and Adams Counties, and continuing southeast to Ringgold and Decatur Counties, shows abnormally dry conditions, despite the recent, but spotty rains. The far southwest corner of Fremont County is also abnormally dry, while the remaining western third of the state shows normal soil moisture.
