NWS Des Moines, IA wrote its last area forecast discussion before the first event at Jun 7, 2:21 AM CST, 2 hours 39 minutes earlier.
Area Forecast Discussion National Weather Service Des Moines IA 321 AM CDT Tue Jun 7 2022 .DISCUSSION.../Today through Monday/ Issued at 321 AM CDT Tue Jun 7 2022 Key Messages: - More showers and storms by later today. Few could be strong to severe southwest. - Near to below normal temps and periodic chances for showers and storms continue through the end of the week into the weekend. Quasi-zonal pattern remains active as water vapor imagery shows the next PV anomaly tracking east through the northern Rockies. More showers/storms are likely by later today as the wave rides into the northern Plains and upper kinematic support overspreads the state. Severe potential looks rather marginal for most of the CWA today, but west/southwest Iowa may be more favorable as ML Cape increases to around 1000-1500 J/kg by later in the day. Hi- res models initiate deeper convection over Nebraska by 21z and drag the storms east to southeast. HREF members suggest this activity may mature into an MCS and travels across southwest Iowa later in the evening. Latest runs of the HRRR are more of a north/east outlier and bring some scattered stronger convection into central Iowa, so this trend will also need to be closely monitored to see if other hi-res members follow. While the instability isn't overly impressive, deep layer shear will be supportive of organized storm structure and a threat of large hail and damaging wind. A tornado cannot be ruled out if cells remain discrete, but weak low level shear is a limiting factor. The severe threat wanes for any storms activity further north/east across the state. Additional storms are possible late in the overnight along a frontal boundary sagging through the state. It is unknown if earlier convection shooting south will disrupt northward moisture transport and hamper redevelopment potential. Regardless, instability is paltry by this point and poses little to no severe threat. HREF PMM QPF is not overly bullish and mostly 1" or less, but any heavy rainfall in recently water logged areas could trigger some additional hydro issues. Any lingering shower/storms activity pushes east Wednesday AM. Upper northwest flow amplifies on the backside of the departing shortwave and will keep temps below normal for Wednesday into Thursday. Models suggest cold air advection and steep boundary lapse rates may foster diurnal shower activity Wednesday afternoon. Mean deep layer subsidence aloft may be tough to overcome so confidence in any shower activity materializing is still shaky. Atmosphere begins to reload later Thursday ahead of the next approaching shortwave trough. Showers/storms are likely by Thursday night and lingering into Friday as the wave slides through. At this time it looks like any appreciable severe weather threat will be limited by marginal CAPE as the axis of deeper instability axis holds to our west and south. Pattern progression amongst models begins to diverge a bit over the weekend, but appears to have improved with the 00z runs. Mean northwest flow remains locked in which should keep temps near to below normal. Additional showers and storms are possible later Saturday into Sunday as another low amplitude wave slides through. Too much uncertainty resides at this time range to comment on possible precip amounts/coverage or any severe weather threat. && .AVIATION.../For the 06Z TAFS through 06Z Tuesday night/ Issued at 1203 AM CDT Tue Jun 7 2022 Mainly VFR conditions expected to continue overnight with the exception of some fog potential. Winds have become light and variable and if clearing can occur, some fog could be possible but will likely not be widespread due to clouds filtering in. These should mainly be VFR clouds but if fog can be realized, MVFR, or lower, conditions may occur between 10-14Z. Not confident enough in coverage to include mention of impacts to any TAF sites, but KFOD and KOTM most likely. Winds expected to increase tomorrow afternoon and become out of the south/southeast. Shower/storm chances increase late tomorrow afternoon/early evening and additional mentions will likely be needed in the next issuance. && .DMX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION...Martin AVIATION...KCM
