Area Forecast Discussion National Weather Service Des Moines IA 1203 AM CDT Fri Jul 1 2022 ...Updated for the 06z Aviation Discussion... .DISCUSSION.../Tonight through Thursday/ Issued at 240 PM CDT Thu Jun 30 2022 Key Messages: -Rain and storm chances tonight more focused after midnight -Precip chances increasing especially for areas south on Saturday -Continued active pattern into the middle of next week. A blanket of high-based clouds moved across northern and central Iowa this afternoon. Some light rain has shown up on radar in areas north today, but has had a hard time reaching the ground due to the substantial amount of low-level dry air. PoPs have been kept low today to reflect this. Morning soundings had sizable low-level dewpoint depressions and warm mid-levels advecting into the area throughout the day, adding to the inhibition of convection later this evening. Slightly more favorable conditions exist in areas northeast and southwest where forcing will be stronger. Soundings for central Iowa, the in-between region, keep dry, capped low levels along with weak convergence along the stalling boundary. Higher CAPE values combined with an "inverted v" hybrid profile, the chance for a conditional hail and strong downburst potential, though small. CAMs continue to trend dry until the boundary sinks into southern Iowa late overnight/early Friday when a better moisture tap is available. While locally heavy rainfall is possible with this, the threat for severe weather is minimal. The newest HREF PMM 24 hour QPF continues to have very small areas receiving up to 1.5 inches of rainfall therefore the threat for any hydrology impacts is low. After brief redevelopment of precip on Friday afternoon in portions of Missouri, the boundary will retreat back towards the state for another potential for precip on Saturday. An MCS looks to form in the Dakotas Friday night and sink towards the state, however due to the tight moisture gradient that exists over the northern and eastern portion of the state, confidence is low that the MCS would sustain itself long enough to affect the state. Multiple rounds of embedded energy is hinted at in models into the first half of next week. The strongest wave looks to be Sunday night into Monday where an MCS will pass through the state. Deterministic runs and ensembles continue to hint at this possibility. Continued redevelopment of rain is possible into next week due lots of moisture potential and the nocturnal jet nose being fixated nearby. Broad-brushed PoPs have been kept in the long term due to uncertainties of boundary placement and timing. && .AVIATION.../For the 06Z TAFS through 06Z Friday night/ Issued at 1158 PM CDT Thu Jun 30 2022 VFR conditions generally expected to prevail through the TAF period though some MVFR conditions could occur briefly with heavier showers. Showers with a few thunderstorms remain possible overnight into Friday morning. Recent trends continue to push activity further south and starting later and have adjusted timing accordingly with KOTM the most likely site to be affected by any showers/storms. Kept with a VCSH at KDSM during the most likely time period of showers, though activity may be further south. Timing may still need to be further refined with scattered nature of showers/storms and thus lower confidence in exact timing of impacts. && .DMX WATCHES/WARNINGS/ADVISORIES...
