The episode as NWS DMX wrote it up.
Another day with gusty winds across the state. Most sites saw gusts into the 30 to 45 mph range. However one location in Clive, IA in the DSM Metro reported some tree damage from the wind gusts. The highest gusts seemed concentrated across central, southern and southeastern Iowa.

Area Forecast Discussion National Weather Service Des Moines IA 324 PM CDT Tue Apr 30 2019 .SHORT TERM.../Tonight through Wednesday/ Issued at 325 PM CDT Tue Apr 30 2019 Surface low continues to be located across NW TX with an inverted trough feature stretching northeastward into OK and KS and MO. Iowa remains to the north on the cold side of the system which has resulted mainly drizzle and showers across the area today. This trend is expected to continue into this evening. However the stronger shortwaves ejecting ahead of the main upper trough continues to lift through the central/southern Plains currently and will allow for the large area of showers across NE KS and northern MO to translate northward into Iowa, especially southern Iowa this evening. Maybe a thunderstorm still embedded in the far southeast, but instability expected to be fairly limited and therefore suspect majority of the activity to be showers and little thunder. Some additional shower development expected late this evening into tonight across the central/north with shortwave moving through CO to lift through NE/IA late tonight. This activity should diminish and move east toward sunrise and through the morning hours Wednesday. Another shortwave moving through the main upper trough currently dropping through NV will eject eastward through the state late Wednesday night into early Thursday. This will bring another chance for some widespread showers and a few storms. No severe storms are anticipated, but another widespread quarter of an inch of rain is possible. Overall conditions will continue to be cool and cloudy with regards to temperatures tonight into tomorrow night. Could see temps approach 60 into the low 60s in the far south/southeast for Wednesday. .LONG TERM.../Wednesday night through Tuesday/ Issued at 325 PM CDT Tue Apr 30 2019 Confidence: Medium to High Next system to affect Iowa is currently over Nevada/Utah and is expected to track east-northeast. H500 pattern shows one wave which is expected to split into two separate wave; one into a northern/southern stream component each as it crosses the Rockies and enters the High Plains. The northern stream wave will reach northern Minnesota by 12z Thursday while the southern stream wave will quickly eject northeast into the mid-Mississippi River Valley about the same time. Neither wave will amplify much, but with a sub-tropical high anchored over the southeast coast; ample moisture will again be available for showers and thunderstorms with the southern stream wave. With the persistent southwest upper flow and high locked in place over the southeast US, an upper level boundary will continue to sit just south of the state and provide continued lift with each wave that passes near it. Clouds will again thicken up early in the period with showers and scattered thunder southeast spreading over most of the area through the overnight. Clouds and showers should keep temperatures in the 40s to 50s over the region Wednesday night. There are some timing differences with the departure of the system on Thursday. The NAM is quickest with the GFS next followed by the Euro. Despite the differences, there is general consensus that clearing will be on the way by the afternoon hours as a ridge of high pressure builds into the region. H850 temperatures will recover to 3 to 4C by 00z. This should help push into the 50s north to the lower to mid 60s south. Over the next 36 hours the upper level pattern relaxes with little available shortwave energy approaching until a northern stream system enters the Northern Plains by Friday morning. Though moisture will be somewhat limited, there may be some scattered showers later Friday afternoon into Friday night as as weak front passes through the region. Depending on the timing of the Friday boundary, Saturday may actually turn out to be a dry day. Right now, confidence is a bit lower on timing. Temperatures will be on the mend into the weekend with 60s for Friday and 60s/70s on Saturday. Even a modest amount of sunshine with H850 temps pushing 6 to 8C should elevate highs into the lower to mid 70s south. For now will not vary too much from current forecast, but consider slightly warmer temperatures Saturday if the current trends hold. /Sunday through Tuesday/... Confidence: Low to Medium There is generally less agreement with timing of features in the last portion of the extended. Through Sunday there is good agreement with a trailing and weakening cold front into Sunday morning. The main difference in the Euro/GFS is the extent of the speed of the parent H500 wave over southern/Central Canada. Despite a slower GFS than the Euro, the outcome is pretty much the same. The timing of the showers and overall expected temperatures are very similar in the upper 60s/lower 70s for Sunday. The remainder of the forecast is still much more uncertain with the timing of the large scale system next week. The Euro is actually faster with the onset of precipitation Monday than the GFS and also warms the region up significantly Monday afternoon. There may be a need to raise temperature 10 to 15 degrees early next week if the Euro is more correct. Eventually with another large scale southwest trough becoming established by Tuesday, the pattern going forward appears to be wet and mild. && .AVIATION.../For the 18Z TAFS through 18Z Wednesday afternoon/ Issued at 1246 PM CDT Tue Apr 30 2019 Continued showers and some drizzle through much of the forecast period. Thunder chances look to be fairly isolated and mainly impacting KOTM late this afternoon into this evening. Otherwise mainly IFR to MVFR CIGS in place this afternoon and will remain in place through the period, potentially dropping to LIFR/IFR tonight. Easterly winds to increase some into this evening, then shift around to the northeast to north/northwest into Wednesday. VSBYS also expected to remain in the MVFR range to possible IFR range through the period with the precipitation chances. && .DMX WATCHES/WARNINGS/ADVISORIES...
