'24-'25 Winter Storm #8
15 Jan 2025 05:30 AMWhile not much for a winter storm, an isolated area near Fort Dodge reported the IEM-analysis-map-arbitrary total of at least two inches of snow overnight into Tuesday morning. Totals an inch or less were common over the rest of the state. Other reports of an inch were found in a line from Fort Dodge to Davenport. The forecast continues to show warming temperatures for the rest of this week before a significant cold air outbreak arrives for early next week.

'24-'25 Winter Storm #7
06 Jan 2025 08:01 AMA major winter storm brought freezing rain and heavy snow from Kansas to now D.C. Iowa barely got clipped by the event with a sharp northern side gradient to the heaviest snowfall totals as dry air over Iowa fought off the snow. The featured analysis is struggling to show the tight gradient that exists over the southern tier of Iowa counties with a limited number of reports in the area. Our recently active weather pattern looks to settle down a bit this week with seasonal cold air in place and not much in the way of precipitation chances.

'24-'25 Winter Storm #6
02 Jan 2025 10:28 PMA compact and quick moving winter storm dumped a stripe of two to four inches on Thursday between roughly Sioux City to Davenport. The featured map presents an analysis of mostly NWS Local Storm Reports as much of the once-daily COOP data will be arriving Friday morning. So the map will be updated once those additional reports arrive along with any CoCoRaHS reports. The map also plots the three Snow Squall Warnings polygons issued by NWS Des Moines as intense snowfall rates impacted the morning work commute. Attention is quickly turning to a much larger storm complex forecast to arrive late this weekend, with the largest snowfall totals forecast to clip southern Iowa along with a sharp gradient in totals to the north.

'24-'25 Winter Storm #5
01 Jan 2025 12:54 PMWhile most of the precipitation from the storm impacting the state Monday into Tuesday fell as rain, a few locations picked up measurable snowfall with an isolated area west of Des Moines picking up over two inches. The featured map presents available NWS COOP, Local Storm Reports, and CoCoRaHS reports over the past two days. Some of the snow did quickly melt with the change over to rain, so totals were difficult to measure and report. Our weather pattern looks to remain active to start off 2025 with the next accumulating snow storm arriving Thursday and a likely bigger storm to end the upcoming weekend.

'24-'25 Winter Storm #4
20 Dec 2024 08:18 AMA prolonged period of snowfall starting late Wednesday evening brought a few inches of snowfall over the northern tier of Iowa counties. The heaviest totals approaching four inches were found over extreme northeastern Iowa. There additionally was some minor freezing rain with this event as well. Winter Road Conditions are currently partially snow and ice covered this Friday morning over northeastern Iowa. Unfortunately, this snowfall will not stick around for Christmas next week as a number of days with above freezing temperatures are expected for the area.

'24-'25 Winter Storm #3
18 Dec 2024 08:20 AMWhile not much for a winter storm, a quick moving system brought some rain, freezing, and snow to mostly the northern half of the state. There were a few isolated two inch snow fall reports found over northeastern Iowa, so the arbitrary threshold for IEM map generation / storm counting was triggered. Another quick moving snow producing storm is expected this evening with similar amounts of light snowfall. For those of you hoping this bit of snowfall sticks around for a week, above freezing temperatures are expected next week and even tomorrow, so the chances of a White Christmas are very slim at the moment.

'24-'24 Winter Storm #2
15 Dec 2024 08:30 PMFriday evening into Saturday brought a significant ice storm to eastern Iowa with the Cedar Rapids to Iowa City corridor the hardest hit. The featured map presents available NWS Local Storm Reports of freezing rain accumulations. The map also plots the extent of the Ice Storm Warnings issued by the NWS for the event. Far northeastern Iowa did also get an inch or so of snowfall along with some freezing rain. Thankfully, temperatures warmed above freezing for much of the state on Saturday and for the entire state on Sunday, which helped to reduce impacts from this event.

'24-'25 Winter Storm #1
03 Dec 2024 05:30 AMThe first wide spread snowfall over Iowa of the season fell on Monday with most locations picking up 1.5 inches or less. There were a couple of isolated two inch reports, so this met the arbitrary threshold for the IEM to generate a snowfall event map. The featured map presents an analysis of available NWS and CoCoRaHS reports. This snowfall was tremendously fluffy with snow to liquid water equivalent (SWE) ratios around 40 and above. A more typical SWE value in Iowa is closer to 13, so it was certainly not much trouble to shovel such fluff away.
