Strong storms bringing heavy rain and winds gusting up to 70-miles per hour raced through western Iowa Sunday morning, causing injuries to a family of three camping in a tent at Lake Manawa State Park. The injuries occurred when a tree fell on the tent at around 5-a.m., Sunday. Elsewhere, there were reports of flooding, hail and downed power lines. The warnings began in our area just before 6-a.m.

According to the National Weather Service at 6:10-a.m., nickel-sized hail was reported by a trained storm spotter in Audubon County, 4-miles west of the Audubon Airport. A few minutes later, the hail was the size of quarters in the same area, and in the City of Audubon itself. A cooperative weather service observer in Audubon also reported 2.67-inches of rain had fallen by 8-a.m., causing flash flooding to occur 4-miles west/southwest of the Audubon Airport, with water covering the County Highway N-14 bridge over the Indian Creek. One-half mile of road was also under water. Another spotter reported 4.5-inches of rain west of the airport.

Meanwhile, in Cass County, law enforcement reported a squad car was rocked by estimated 60-mile per hour winds, just before 6:30-a.m., Sunday, about 4-miles southwest of the Atlantic Airport. Dime-sized hail was also reported. Thunderstorm wind damage was reported in Atlantic at around 6:30-a.m., with some shingles blown off roofs, and 12-to 14-inch diameter trees being snapped.

As the storms moved into Adair County, wind gusts of up to 65-miles per hour were reported 6-miles west/southwest of Greenfield just after 7-a.m. Those same type of winds were observed six-miles north of Greenfield at 7-a.m., causing 12-inch diameter tree limbs to bend at an estimated 10-degree angle.

The storms continued into Central Iowa, where 71-miles per hour winds were recorded near Dallas Center at around 8:30-a.m. Two power poles were snapped-off at the base near Nevada, at around 8:50-a.m., by fierce winds.

DAY ONE…THIS AFTERNOON AND TONIGHT

SCATTERED SEVERE THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON AND EVENING. THE MAIN THREAT WILL BE FOR LARGE HAIL AND DAMAGING THUNDERSTORM WINDS. ISOLATED TORNADOES ARE ALSO POSSIBLE. THE THREAT WILL CONTINUE UNTIL 9 PM THIS EVENING ACROSS THE OUTLOOK AREA. THESE STORMS COULD ALSO BRING HEAVY RAINS ALONG WITH THE THREAT FOR SEVERE WEATHER. LOCALLY HEAVY RAINS AND FLASH FLOODING ARE ALSO POSSIBLE IN SOME OF THE SLOWER MOVING STORMS AS MOISTURE LEVELS REMAIN HIGH ACROSS THE REGION.

DAYS TWO THROUGH SEVEN…SATURDAY THROUGH THURSDAY

OUR RECENT ACTIVE WEATHER PATTERN WILL CHANGE LITTLE THROUGH THE WEEKEND WITH OFF AND ON CHANCES FOR THUNDERSTORMS. A FEW OF THESE STORMS MAY STILL BE SEVERE WITH LARGE HAIL AND DAMAGING WINDS THE PRIMARY THREATS. LOCALLY HEAVY RAINS AND FLASH FLOODING REMAIN POSSIBLE AS WELL. THE BEST CHANCES FOR WIDESPREAD THUNDERSTORMS WILL BE SATURDAY NIGHT AND SUNDAY ACROSS THE REGION. OTHER LESSER THUNDERSTORM CHANCES ARE IN THE FORECAST EARLY NEXT WEEK…BUT THE POTENTIAL FOR SEVERE WEATHER APPEARS LOW AT THIS TIME.

Residents in southeast Iowa’s Henry County are getting a good look at the damage from last night’s (Thursday) apparent tornado. It touched down about halfway between Mount Pleasant and Washington. No one’s reported hurt but several homes and farmsteads were damaged, including a large turkey farm near Wayland. Dozens of neighbors gathered to help round up about a thousand turkeys after the barn was blown away. National Weather Service meteorologist Jeff Zogg says much of the state had severe weather overnight.  “We received a lot of hail reports of one-inch or larger across the northern part of the state and then later in the evening those storms died out,” Zogg says. “The strongest storms occurred in the eastern part of the state where there were a lot of hail reports, a lot of flash flooding occurred.” 

Nickel-sized hail was reported early this (Friday) morning in Adams County. Emergency management officials said the hail fell near Prescott, at around 3-a.m. Zogg says there’s a chance for more thunderstorms across much of Iowa today and through the weekend. “We’re in for an unsettled weekend in terms of thunderstorm activity,” he says. “During the day today, there’s a chance of thunderstorms statewide, better chances this evening and tonight statewide. Some storms this evening and early overnight may be severe with hail and strong winds.” He says Iowans need to keep a close watch on the skies — and the forecast — as conditions can quickly change.

“Any thunderstorm that does develop will have the potential to produce heavy rains and possible flash flooding,” Zogg says. “It looks like there’ll be another chance of thunderstorms during the day on Saturday and into Saturday night and early Sunday. Finally, late this weekend, Sunday night into Monday, a cold front will push through the state and take a lot of the thunderstorm activity and humid weather with it.”  High temperatures topped off in many Iowa cities in the 80s and 90s this week. He says highs by Monday may only be in the 60s and 70s.

FOR MONONA-HARRISON-SHELBY-POTTAWATTAMIE-MILLS-MONTGOMERY-FREMONT & PAGE COUNTIES IN WESTERN IOWA….

THERE IS A SLIGHT RISE FOR SEVERE STORMS ACROSS ALL OF THE OUTLOOK AREA BEGINNING LATE THIS AFTERNOON IN NORTHEAST NEBRASKA…THEN THROUGH THE EVENING ACROSS THE REST OF EASTERN NEBRASKA AND SOUTHWEST IOWA. LARGE HAIL WILL BE THE PRIMARY HAZARD WITH DAMAGING DOWNBURST WINDS A SECONDARY CONCERN.

INCREASING HUMIDITY ON SOUTH WINDS ALONG WITH AFTERNOON HEATING WILL PRODUCE A VERY UNSTABLE ATMOSPHERE IN THE OUTLOOK AREA. A STATIONARY FRONT DRAPED ALONG THE SOUTH DAKOTA BORDER SHOULD PROVIDE THE FOCUS FOR THUNDERSTORM DEVELOPMENT THIS AFTERNOON…AIDED BY A MID LEVEL WAVE MOVING IN FROM THE WEST. ANY STORM THAT DEVELOP NEAR THIS STATIONARY WILL HAVE A SMALL CHANCE TO PRODUCE A TORNADO. THIS ACTIVITY IS EXPECTED TO DRIFT OR DEVELOP SOUTHEAST ACROSS THE REST OF EASTERN NEBRASKA AND SOUTHWEST IOWA DURING THE EVENING…WITH LARGE HAIL POSSIBLE.

SATURDAY THROUGH THURSDAY…

SEVERE THUNDERSTORMS ARE AGAIN POSSIBLE SATURDAY EVENING AND SATURDAY NIGHT. A VERY UNSTABLE ATMOSPHERE WILL BE IN PLACE SATURDAY AFTERNOON BUT WARM MID LEVEL TEMPERATURES SHOULD CAP ANY DEVELOPMENT UNTIL A COLD FRONT APPROACHES FROM THE NORTHWEST. THAT FRONT SHOULD BE MOVING INTO NORTHEAST NEBRASKA DURING THE EVENING…THEN SWEEP THROUGH THE REST OF EASTERN NEBRASKA AND SOUTHWEST IOWA OVERNIGHT. LARGE HAIL WILL BE POSSIBLE WITH ANY
THUNDERSTORMS…EVEN THROUGH THE OVERNIGHT HOURS…AS INSTABILITY WILL REMAIN HIGH.
