Damaging Winds in Iowa, June 17, 2016
A wave riding the northwest upper level flow through the Dakotas and Northern Minnesota initiated a series of storms that eventually topped the ridge and started southeast. The storms eventually initiated along an outflow boundary, taking them due south into northern Iowa, where they produced periods of heavy rain and a few damaging and high wind reports near Estherville.

Area forecast discussion, Jun 17, 5:23 PM CST, 1 hour 9 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 623 PM CDT FRI JUN 17 2016 .UPDATE... Issued at 608 PM CDT Fri Jun 17 2016 Have updated forecast for potential MCS backbuilding into far northwest/west counties overnight. Currently complex is pivoting with most active outflow moving SW toward Sioux Falls. Will continue to monitor...added chances to far northwest with surrounding slight chance. Possible a few stronger storms will move through far NW as well. Threats would be wind/hail. Remainder of forecast on target./rev && .SHORT TERM.../Tonight/ Issued at 317 PM CDT Fri Jun 17 2016 High pressure still off to the east with return flow into ERN NE/far western IA and ERN SD. Sfc boundary stretching east across ERN SD with a few storms forming over the past hour across EC SD and WC MN. Activity has been ongoing across central MN through the day and areas may merge with an area of convection sliding southward along the instability axis as moisture transport begins to veer into ERN NE/far western IA this evening/overnight. Large amount of instability present, however deep layer sheer is practically non- existent. Therefore if the complex of storms materializes, the activity could clip the far northwest/west central counties in the CWA. Have included slight chance pops for the far northwestern tier of counties for this chance and expect majority of the activity to remain to the west of the CWA. Severe threat is limited given the lack of shear, however instability is large so an isolated strong to severe storm is possible. Mainly damaging winds gusts would be the severe threat, but an isolated large hail report is possible. .LONG TERM.../Saturday through Friday/ Issued at 317 PM CDT Fri Jun 17 2016 The upper ridge to build in along with the thermal ridge for Saturday into Sunday with h85 temps approaching +24C by Sunday across western Iowa. Heat will build across the state with temps into the 90s for Sunday, and increasing dewpoints as well. Heat index values expected to climb to around 95 to 100 with the highest values off to the west. Upper ridge begins to break down into Sunday night and Monday as a cold front drops through the state. This will bring the next chance for precipitation, however the dynamics with this front to remain further north, thus areal coverage of storms could be limited as moisture also limited. Kept with chance pops mainly late Sunday night north and Monday afternoon/evening central and south as the front drops south. Large area of sfc high pressure then to build back into the region Tuesday into Wednesday with upper ridging building across the western US into the end of the week. This scenario should set up more seasonal temperatures and dry conditions for the majority/remainder of next week. && .AVIATION.../For the 00Z TAFS through 00Z Saturday evening/ Issued at 623 PM CDT Fri Jun 17 2016 Main concern early in the period 00-09z will be MCS over MN this evening moving south/southwest with time. Other than KFOD...not likely to affect any other sites given current progress. Have added VCTS to KFOD around 02z with activing building back SW aft 03-05z and exiting area. Otherwise with high over Great Lakes little additional challenges during period with winds increasing by 15z Saturday SSE ~ 08-16kt across the area with VFR conditions. /rev && .DMX Watches/Warnings/Advisories...
