The National Weather Service in Omaha has extended a HEAT ADVISORY that is currently in effect until 7-p.m. Friday (Today). The ADVISORY now includes the following counties in western & southwest Iowa:
MONONA-HARRISON-SHELBY-POTTAWATTAMIE-MILLS-MONTGOMERY-FREMONT & PAGE, in addition to the remainder of the State. The western/sw Iowa ADVISORY begins at 1-p.m., and expires at 7-p.m.

TEMPERATURES ARE EXPECTED TO CLIMB INTO THE MID AND UPPER 90S THIS AFTERNOON. THE TEMPERATURES WILL COMBINED WITH HIGH HUMIDITY TO CREATE HEAT INDEX VALUES FROM 103 TO 108 FOR A TIME THIS AFTERNOON. THE COMBINATION OF HOT TEMPERATURES AND HIGH HUMIDITY WILL CREATE AN INCREASED THREAT FOR HEAT EXHAUSTION OR HEAT STROKE…ESPECIALLY FOR THOSE WORKING OUTDOORS.

PRECAUTIONARY/PREPAREDNESS ACTIONS... A HEAT ADVISORY MEANS THAT A PERIOD OF HOT TEMPERATURES IS EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND HIGH HUMIDITY WILL COMBINE TO CREATE A SITUATION IN WHICH HEAT ILLNESSES ARE POSSIBLE. DRINK PLENTY OF FLUIDS…STAY IN AN AIR-CONDITIONED ROOM…STAY OUT OF THE SUN…AND CHECK UP ON RELATIVES AND NEIGHBORS.

The recent hot and dry spell has prompted the U.S. Drought Monitor to list nearly a quarter of Iowa in “severe drought.” A week ago, none of the state was in that category. State Climatologist Harry Hillaker says it’s clearly very dry across Iowa, but he disagrees with some of the U.S. Drought Monitor’s new assessment. “Right along the Nebraska border, there was actually a fairly good rain there about a week-and-a-half ago. So, I would have left out Harrison and Pottawattamie Counties (from the severe drought category). They’re still plenty dry, but certainly not as dry as the rest of that area,” Hillaker says.

In far northeast Iowa, a section of Allamakee County is labeled as being in “moderate drought.” Hillaker believes that area shouldn’t be listed in that category just yet. Overall, the U.S. Drought Monitor calls all of Iowa at least “abnormally dry,” compared with 82 percent last week. Sixty-percent of Iowa is in moderate drought and 22.4 percent is in severe drought. Hillaker says the lack of moisture and this week’s extreme heat will likely hurt the development of Iowa’s corn and soybeans.

“The worry with most of the corn and soybeans is it’s going to decrease the yield and the corn kernels themselves won’t fill very well with the lack of moisture, which is going to be worsened by the heat…same with the beans,” Hillaker says. This month is on track to enter the record books as Iowa’s 7th driest August. Last month was the state’s 9th driest July on record.

Hillaker says the two months combined have produced the 4th lowest precipitation total in 141 years of records. “The only ones lower were all a long time ago with 1947 being the most recent one. The other two were back in the 1800s,” Hillaker says. The dry spell, which started back in June, follows Iowa’s wettest ever spring. Over the months of March, April, and May, Iowa received a statewide average of nearly 17.5 inches of rain. That was over two inches above the previous record, which was set in the spring of 1892.

DES MOINES, Iowa (AP) — A growing season that began unusually wet and cold in the Midwest is finishing hot and dry, renewing worries of drought and its impact on crops. Experts say corn and soybeans may not have enough moisture in dry areas to develop to full weight, which could reduce this year’s harvest.

The weekly Drought Monitor report released Thursday shows that lack of rain has caused drought conditions to expand in parts of Illinois, Indiana and Michigan, and most of Minnesota and Wisconsin. It also shows that abnormally dry conditions have expanded in eastern Iowa and South Dakota. Rain eased drought in portions of northern Nebraska, but much of the western half of the state remain in extreme drought.

But the drought monitor showed improvement in some states, including Kansas.
