Watch our timelapse from Downtown Des Moines as storms push in from the north on Monday night. Gust front turned the crane like a weather vane. Nice shelf cloud in tow too. Vivid lightning show too with this line as it moved through just after 10 PM. #IAWX #DSM #DesMoines

Mammatus dropping down out of the anvil of departing t-storms this evening in north Iowa. As seen near Mason City looking east. Awesome looking shot. 📷Susan Janssen 📍Near Mason City, Iowa #IAWX #Mammatus

Mammatus popping down under the anvil of storms over north Iowa. This is seen from Floyd County tonight, south of Nora Springs. Beautiful. 📷Jo Hain 📍South of Nora Springs, Iowa #IAWX #Mammatus

Just a ton of small hail covering the ground in Cerro Gordo County, Iowa this evening from a severe storm. I'm told most of this was 1/2" in diameter or less... but a lot of it! 📷JP Midwest Storm Chaser 📍South of Clear Lake, Iowa #IAWX #Hail

Storms earlier this evening showing a lowering up over western Mitchell Co. Had a bit of broad rotation to it too. Tracking these storms as they continue to dip south. Overall, thinking the main threats will be hail & gusty wind. Hearing of a decent outflow with this storm too.

Does it get any more perfect than that? Casey's just painted a giant pizza box on top of the @[147288008641243]. #CaseysPizza #DesMoines #DSM

Awesome view from over 100 miles away! The tops of those storms you see from Downtown Des Moines are way up by Mason City, 108 miles away as a bird flies. Those storms are strong and are trying do dip south. Heads up for hail and wind this evening in northern Iowa. #IAWX #DSM

Here's your Monday evening #Fastcast. Storms bubble up over northern Iowa and push south. An additional wave possible from the west later tonight. Initial offerings could bring hail and wind threats to Iowa, gradually weakening with time tonight. #IAWX #Iowa #SevereWeather

Level 2 Risk on the Severe Weather Outlook for much of north/west Iowa off into Nebraska. Storms look to fire Monday evening, mainly after 6PM. Storms fire north and slowly slip southwards through Iowa. Greatest threat is hail, followed by wind. Threat time from 6p-12a. #IAWX #Iowa

Look at all that hail fall to the ground near Hope, MN! Hail fell for a few minutes and ultimately ended up covering a lot of the deck of LeAnn's home! 📷LeAnn F Knudson 📍Hope, MN #MNWX #Hail

Nope... not snow! That's hail! And lots of hail covering the ground south of Hope, MN earlier this evening from t-storms. A couple stones were up to quarter or half dollar size! 📷LeAnn F Knudson 📍Hope, MN #MNWX #Hail

A little cooler for your Saturday. Clouds hang through most of the morning. Showers hug southern Iowa for most of the day. A few popups will be possible north of I80 into the afternoon after a bit of clearing. Warmest temps will be in area north of I80. Low to mid 70s. #IAWX

Corn is all out of the field on ***Checks Calendar*** on September 19th?! That's got to be one of the earliest I've seen in a while. Taken in northern Polk County Friday evening. #IAWX #Harvest #Fall 📷Britt Butler

Ready for racing in Knoxville tonight! A gorgeous sky and avoiding the rain! The final events of the season are happening tonight and tomorrow with the Late Model Knoxville Nationals. #LetsGoRacing!

Big differences in rainfall this week in Iowa— some spots out east saw less than 1/10" , while others soaked up over 3"+! 🌧️🌤️ #IAwx #Iowa #Rain

Here's your Thursday evening #Fastcast for central Iowa. More rain pushing in from the southwest. Look for a few streaks of heavier totals. Focus more over northern Iowa for Friday with scattered rain/storms before returning back south for Saturday. #IAWX #DSM #Iowa #Weather

Quick, everyone! The Pot of Gold is *IN* Morin Lake! Rainbow in southern Minnesota with a late day t-storm earlier this week. 📷Dave Sime 📍Alden, MN #MNWX #Rainbow

Wicked! Lightning spiderwebbing across the sky from a departing t-storm over the Des Moines metro tonight. 📷Cristina Friederch 📍West Des Moines, IA #IAWX #Lightning #Iowa #Storms

Here's your Wednesday evening #Fastcast. More rain chances ahead all the way through the weekend. But coverage isn't quite as extensive for Thursday or Friday. Still, some streaky heavy rain amounts possible and an isolated strong storm too. #IAWX #Iowa #DSM #DesMoines

Shelf cloud! This shelf is radiating out from a cluster of severe storms over southern Iowa on Tuesday evening. Sometimes a signal for strong wind, we've seen a few gusts push to 60+mph near Osceola with this storm. This shelf is seen approaching Chariton. 📷Derek Coker 📍Chariton, IA

Severe storm in southern Iowa over Osceola Wednesday evening had some strong wind with it and some smaller hail. Here's a tree that was taken out at the Hy-Vee store in town. I'm told the rain and wind was quite intense with this storm. 📷Carissa Jacobsen 📍Osceola, IA #IAWX

Double Rainbow over the Fall fields in northern Iowa from 9/15/25. The skies have been a bit more busy as of late. The sun still peaking through provided for this #DoubleRainbow opportunity. #Fall 📷Janelle Furleigh #IAWX #Rainbow

Radar estimates around 4" of rain has caused some problems in and around Ft Dodge. There's reports of stalled out vehicles and water covering roads, like what's shown here under the Kenyon Rd. Bridge along the Des Moines River. 📷Brooke Varland 📍Fort Dodge, IA #IAWX #flooding

Here's a look at your Tuesday evening #Fastcast for central Iowa. More rain on the way for Wednesday with better coverage across Iowa. Totals range widely. A soggy stretch continues through the end of the week. #IAWX #DSM #DesMoines #Forecast

A great look at a couple of storms pulsing up, but still in their infancy looking south of the Des Moines metro earlier this afternoon. Such an artistic shot! 📷Cristina Friederich 📍West Des Moines, Iowa #IAWX #Iowa #DSM

Good morning from central Iowa! A beautiful start to the day with the sun rising above the horizon, peaking between the morning clouds. This gorgeous shot was taken near Boone! Let's see your #sunrise/#sunset shots in the comments! #IAWX 📷Jon Hathaway 📍Boone, IA

Expect sparse pulsing showers and storms to build up across central Iowa after 2 PM continuing through the evening. Coverage won't be too great, but much like tonight, if you do see them, you could easily pick up a decent amount. Severe prospects are low. #IAWX #DSM

Nice colors mixing in to the trees over northern Wisconsin along US highway 8. Not near peak or anything but definitely more advanced than some areas further south like Iowa! 📷Danny Werner 📍Northern Wisconsin #WIWX #FallColors

Some color is starting to work into the Fall landscape in Iowa with some early turning of the leaves in Walnuts and sumac in the ditches. But overall, the color change is minimal. Starting to see color a bit more prominent in northern ND, MN, WI and the UP of MI. #IAWX

Here's your Monday evening #Fastcast for central Iowa. We're looking at daily rain chances through the end of the week. But there's a couple days where rain is more prominent than others. Temperatures are gradually on the decline but will the bottom drop out? #IAWX #DSM #DesMoines

An absolutely stunning shot of the Northern Lights shining through the holes in the clouds in the southern Minnesota night sky! Great capture! 📷 Amanda Hanenberger 📍 Dodge Center, MN #NorthernLights

Missing this yet on a hot September day? It's closer than you might think. #Blizzard #Snow #Winter

I got Blitzed, y'all. #FUMBLE!!! Tom Brady must have been at the studio and deflated the ball on me! #Local5Blitz #Blooper

Starting to see some color materialize way up north in Minnesota. I've seen a few yellow popping in locally across Iowa. But we've got a ways to go before reaching Peak Fall Color. That average peak is around mid to late October over southern Minnesota down into Iowa. #IAWX #MNWX

For September... these temperatures are getting up there. Quite possible a record high comes into play for Des Moines on Saturday. 95° forecasted. 96° is the record. As far as a heat index... a few may make upper 90s but this isn't a 'humid' setup. #IAWX #DSM #DesMoines

Here's a look at your #Fastcast! It's a hot Saturday coming in. Highs will commonly hit the mid 90s across Iowa. Near a record for Des Moines. This round of Summer won't be too humid with only slight rises leading to a degree or two increase for the heat index. #IAWX #DSM

Turning up that HEAT! Friday temps target the low 90s south of US 30 in Iowa. 90s take over the entire state on Saturday. Mid 90s will be common. If you're lucky, the heat index may be a degree or two hotter at times, but largely negligible. #IAWX #DSM #DesMoines

Tricky forecast for rain tomorrow. It's a balancing act between light radar returns and dry low levels in the atmosphere. Hi-Res data is pushing a little light accumulations, mainly over north Iowa with the returns being able to overpower the dry air. #IAWX #DSM

Going to be a hot one on Friday for the southern half of Iowa. Temps are in the 90s but feeling... cooler? Yes, the moisture component just isn't there. Your sweat will help you cool better in a dry environment. Either way, it's 90 degree day for most areas south of US30. #IAWX

A stunning monarch butterfly takes a rest on a zinnia with striking contrast. Nature sure has a way of making its own art. It's shown in full display here. 🦋 📷Jon Hathaway 📍Boone Co. Iowa #Butterfly #Monarch #Fall #MonarchMigration

Temps are trending upwards for the end of this week. By Saturday, we're looking at the highs pushing towards record range. Mid 90s are possible to start the weekend. Talk about #Whiplash from those morning temps in the 40s last Sunday! #IAWX #Iowa #IowaWeather #DSM #DesMoines

About to turn up that heat. Each day in the next three is hotter than the previous. Saturday is the hottest with low/mid 90s in central Iowa. Relative humidity levels aren't a huge factor this time. #IAWX #DSM

Here's a look at your #Fastcast on this Monday evening! Fall-like conditions are being set aside for the return of summer. We'll go from near record low temperatures to near record high temperatures in about a week! 90s are returning by Friday/Saturday. #IAWX #DSM #Iowa

What a swing! From near Record Lows last weekend to near Record Highs this weekend. Saturday's high of 94° in Des Moines is within a stone's throw of the record high of 96° set back in 1939. We'll be on temp watch once again. #IAWX #DSM #DesMoines

A fiery sky as the sun slips to the horizon on Sunday evening in southern Iowa. A picture perfect Fall evening in Leroy! 📷Greg Watsabaugh 📍Leroy, Iowa

Some beautiful sunsets over the weekend. This on on Friday night down in Chariton with a warm glow on the horizon. 📸Austin Hamilton 📍Chariton, IA #IAWX #Sunset

Fall this weekend, Summer this week. Temperature take the jump up across central Iowa this week. Building up to some pretty warm readings by the end of the week. #IAWX #DSM

Sunday's low temperature for Des Moines is expected to be just off record territory. 42° would tie for the second coldest ever recorded on September 7th in Des Moines. Widespread low 40s with some upper 30s are expected across Iowa Sunday morning. #IAWX #DSM

Coldest Low Temps on September 6th for Des Moines. Saturday's low will be down with the coldest on the date. It'll be our coldest on this date since 1988 when it was 42°. Widespread low to mid 40s are expected across Iowa Saturday morning. #IAWX #DSM

Frost potential for many in the Upper Midwest early Sunday morning. More prevalent across Northern Minnesota and North Dakota, a few frosty spots are possible as far south as Iowa. #IAWX #MNWX #NDWX #Frost
