DES MOINES, Iowa (AP) — Smoke from wildfires raging in Colorado has drifted into Iowa, making for redder skies at dawn and dusk but causing no health problems. The Des Moines Register says the smoke will likely remain over the state until the fires are out. The National Weather Service says the smoke is high in the atmosphere, so residents likely won’t see too many effects. Meteorologist Kevin Skow says winds, which generally flow from west to east across the U.S., has pushed the smoke over Iowa. He says the sky is hazier, and sunrises and sunsets will be redder than normal. Meteorologists haven’t notices any dust or other particles that could settle on the state and aren’t aware of any health risks. Environmental officials say Iowa’s air quality is good.
Iowans shouldn’t expect any relief from the extreme heat this week. National Weather Service meteorologist Miles Schumacher says it’ll be hotter than usual for the first week of July. “It’s going to remain hot all week with mid 90s (for highs) and temperatures staying in the 70s throughout the night,” Schumacher said. A heat advisory covering northwest Iowa runs from noon today until 7 p.m. on Friday. An additional heat advisory is posted for northeast Iowa from noon until 10 p.m. today only.
“One thing we don’t have that a lot of times we have is the extremely high humidity,” Schumacher said. He credits the mostly dry conditions over the past few months for the lack of humidity. The best chance for rain and slightly cooler conditions won’t arrive until late next weekend. “It’s looking like…Sunday and Monday we’ll see some cooler air and temperatures getting back to normal in the middle 80s for highs. It’s looks like we do have a chance for some much needed rainfall by Sunday and Monday,” Schumacher said.
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.
Yesterday’s High in Atlantic was 94. Our low for the 24-period ending at 7-a.m. today will be 70. Overnight, we were in the upper 70′s. Rainfall last month amounted to 3.95-inches, or about 2-tenths of an inch below normal. Normal rainfall for the month is 4.16″. The average High in June was 85.3-degrees, which was nearly 3-degrees warmer than normal . The Average Low last month was 61.1-degrees, which was also 3-degrees above normal.

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.
