Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1.

(Radio Iowa) – Forecasters say heavy showers are likely this (Friday) afternoon and evening for western and central Iowa, but it would take many more rains to make a dent in the long-running — and worsening — drought. State climatologist Justin Glisan says the new drought maps released late this week show drought conditions widening and getting more severe, especially across Iowa’s northern half.

“We’ve had drought expand across the state, especially the D-3 category, which is extreme drought,” Glisan says. “Looking at the previous maps, this is the largest extent that we’ve seen across northern Iowa since the early part of April in 2013.” The new climate outlook was issued for the region on Thursday and Glisan says it holds no obvious signs for what’s to come in the long-term.

“We have an equal chance of above, below or near-average temperature and precipitation behavior in the month of September,” Glisan says. “Then looking at meteorological fall — September, October, November — we do see elevated chances of warmer temperatures but again no clear signal for the precipitation side.” Fall will arrive in about a month, September 22nd, and Glisan says it’s a toss-up as to what the season ahead may hold.

“We do have a pretty good chance of moving back into a La Nina phase of the El Nino southern oscillation which impacts the jetstream over the United States,” Glisan says. “If we look at analog years in which La Nina has returned to the state, we don’t get a clear signal on precipitation behavior.”

The map shows at least parts of 22 Iowa counties are now in extreme drought, which covers more than ten percent of the state, up from around seven-percent last week. Fifty-five percent of the state is now in some level of drought, while almost 79-percent of Iowa ranges from abnormally dry to extreme drought. Only a few counties in southwest Iowa and most of the southern two tiers of counties are untouched by the dry weather.
