What forecasters said that day
The local office's own words before this wind advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Des Moines, IA wrote its last area forecast discussion before this wind advisory went out at Mar 27, 11:52 PM CDT, 3 hours 7 minutes earlier.
Area forecast discussion, Mar 27, 11:52 PM CDT, 3 hours 7 minutes before
Area Forecast Discussion National Weather Service Des Moines IA 1152 PM CDT Fri Mar 27 2020 ...Updated for 28/06Z Aviation Discussion... .DISCUSSION.../Tonight through Friday/ Issued at 337 PM CDT Fri Mar 27 2020 The weather will be quite active into the weekend with fog, severe thunderstorms and wind all concerns at various times. The parent long wave trough was still well to our west this afternoon approaching the Four Corners area with a stream of moisture moving into the MO Valley. The associated surface features resulted in a frontal boundary from OK through MO and IL with a weak surface wave over western MO. Cool easterly flow was in place across IA under an inversion per the 19z surface analysis but temps were well through the 70s and dewpoints through the 60s by central MO in the warm sector. This low level baroclinic zone is expected to push northward into tonight reaching northern MO and will eventually push 1000+ j/kg MUCAPEs into southern IA into early Saturday. This will develop scattered convection, which could potentially be severe as extreme effective shear develops aloft /50-70kts/. The moist low level inversion will keep hail the primary threat into the morning. Underneath the inversion widespread fog is expected, and may require an advisory later this evening depending on trends. By tomorrow at 18z the surface low will still be to our west over eastern NE, but the warm front is expected to reach IA resulting in temps well through the 60s central and south, and possibly 70+ southeast. This will also result in a small wedge of surface instability into southeast IA with uncapped MLCAPEs 1-2K j/kg. The areal coverage will be limited however as the dry line occludes along the front. Soundings suggest the window between inversion and adequate mixing and low level moisture is brief, three hours or less, so this coupled with very fast storm motion of 40-60kts depending on storm mode will keep our severe window minimal. There are some questions whether discrete cells can be anchored to surface features versus being somewhat elevated and driven by the lobe of kinematic forcing, so all these factors will keep the confidence in severe weather somewhat low this far west. However there is some wind and even tornado potential with 0-1km SRH expected to briefly approach 200-300 m2/s2 with low LCLs due to lingering low level moisture from earlier in the day. As the dry line exits the area, appreciable precipitation is anticipated along the deformation zone over western and northern IA and will be immediately followed by increasing NW winds as the surface low reaches the Upper MS Valley tomorrow night. Although stratus is expected to remain in place, wind speeds, especially gusts, may approach advisory criteria /45kts/ overnight into Sunday morning. The next precip window appears to be Tuesday into Wednesday generated by a compact short wave tracking through the central Plains and OH Valley, and then a separate northern stream short wave into the upper MO Valley. Much of the thermodynamic and kinematic forcing associated with the first wave stays to our south, and anything with the northern wave is brief into Wednesday morning north. The CMC is the most aggressive, as were suggestions from previous runs, but if this trend continues PoPs in this window may be too high. Later into next week confidence decreases further with various model solutions regarding the evolution of the large long wave trough from SW Canada into the northern CONUS. Models have had little run to run continuity regarding the degree of ridging and placement of the upper low to our north. The forecast is essentially dry until model trends become more clear, but Thu would be a potential precip window if 12z run trends remain stable. With fairly zonal flow, no temperatures extremes are anticipated. && .AVIATION.../For the 06Z TAFS through 06Z Saturday night/ Issued at 1152 PM CDT Fri Mar 27 2020 Active TAF period expected. TAF period begins with low ceilings and visibilities along with DZ/RA/SHRA. Some TSRA is possible overnight in SE IA including KOTM. Conditions generally improve Saturday afternoon, however TSRA is possible again at most TAF sites. Some of the TSRA in the KOTM/KALO vicinity may be strong/severe, with all modes of severe weather possible. Strong storm threat is not expected to make it as far west/northwest at KDSM. && .DMX WATCHES/WARNINGS/ADVISORIES...NONE. && DISCUSSION...Small AVIATION...Zogg
