| Episode narrativeepisode_narrative | Early reports starting on the 9th are in this entry, with several later reports starting on the 13th in Part II. ||Additionally the combination of heavy snowpack and heavy rainfall absorbed into the snow partially collapsed a horse barn roof in rural Adair County near Greenfield. ||An ice jam occurred in Ottumwa on the Des Moines River causing flash flooding were water rapidly rose several feet on the morning of the 12th. Several cars and campers were flooded.||A relatively deep and widespread snowpack existed across the region during early to mid March. Many areas in central and northern Iowa had around a foot to two feet of snow on the ground, along with many areas in upstream river basins in Minnesota and the Dakotas having similar or deeper snowpacks on the ground. Additionally, with the below normal temperatures throughout the majority of the 2019 year to date, soils were frozen to depths of a foot or more throughout the aforementioned areas. All of that primed the area for potential moderate to major flooding issues should a rapid snowmelt and/or rainfall event occur, which unfortunately came to fruition.||The primary driver was two-fold with warm air advection on the backside of a departing high pressure on the 12th, and a sizable low pressure system that moved through the region on the 13th and 14th. The event began with widespread temperatures and dew points in the upper 30s to low 40s on the 12th with the initial warm air advection, which continued through the overnight hours into the 13th. As the low pressure system developed off the Colorado Rockies, warm air advection continued to push temperatures and dew points up into the upper 40s and low 50s on the 13th and 14th, aiding the rapid snow melt. On top of the rapid snowmelt, which often went from 12 or more inches on the ground to zero in a matter of about two days, light to moderate rainfall occurred ahead of and on the backside of the low pressure system on the 13th and 14th. All combined to cause widespread overland flooding, river flooding, and ice jam issues. |
| Event narrativeevent_narrative | A heated horse barn near the town of Greenfield experienced a partial roof collapse due to the snow and rainfall absorbed into the snow putting too much weight on the that part of the roof. Minor injuries to a couple of horses were reported. |
