837 FXUS63 KEAX 092027 AFDEAX Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 227 PM CST Sat Nov 9 2024 .KEY MESSAGES... * Stratus and light rain/drizzle continue to exit the CWA this afternoon, giving way to clear skies * Quiet conditions much of rest of forecast, one chance for rain - Tuesday overnight into Wednesday, showers/iso thunder * Temperatures generally a couple/few degrees above normal - Highs upper 50s to 60s - Lows mid 30s to 40s && .DISCUSSION... Issued at 226 PM CST Sat Nov 9 2024 Not difficult to see the regional weather maker on any number of satellite products, the cutoff low pressure system centered near the western/central Nebraska-Kansas border. Visible and water vapor satellite products drive home the wound up nature of the system with a pronounced dry slot across E Kansas up into SE Nebraska wrapping around its core. Warm conveyor belt out ahead of the dry slot gave the area its dreary conditions overnight last night into today, including periods of drizzle lingering after the appreciable rain pushed off to the E/NE this morning. Fortunately, as of early this afternoon the dry/clear slot has begun to work into/through portions of the western CWA. Unfortunately, given the trajectories, clearing will be more gradual through the remainder of the afternoon and evening. Winds will continue out of the S around 10 mph with occasional gusts to around 20 mph. While much of the CWA should see ample sunshine Sunday, upper low track, NE across Nebraska/Iowa, may keep some degree of cloud cover over NW/N portions of the CWA through Sunday before more substantial high pressure influences move in. Any measurable precipitation should remain north into Iowa. Early to mid week will see degree of upper level ridging move across the central CONUS in conjunction with large surface over over the Northern Plains. Modest 850mb temps, for this time of the year, around 8 to 10 deg C will help allow temps reach into the mid and upper 60s, possibly touching 70 Monday with peak ridging overhead. A few degrees cooler Tuesday onward with ridge passage and 850mb temps easing. Next opportunity for rain will be Wednesday/Thursday time frame as progressive longwave trough moves across central CONUS. Synoptic guidance varies in passage currently, with GFS/GEFS quicker than the Euro and its ensemble. Regardless, nothing terribly exciting in depictions, with plenty of dry air in place ahead of it, modest moisture return, and poor lapse rates/little to no CAPE. Toss on top of that strongest lift may be displaced northward some and the result is modest PoPs and potential QPF. With some of the timing uncertainty and dry air, do not have issue with PoPs in the 30s percent, nor QPF only around a tenth to quarter inch. Late week into next weekend will see dry conditions and a more notable upper ridge vs early week. As such, potential for temperatures to top out in the upper 60s to low-mid 70s by next Saturday with guidance suggesting double digit deg C 850mb temps. That would be upwards of 15+ degrees F above normal for mid- November. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1123 AM CST Sat Nov 9 2024 Beginning of TAF period will remain highlighted by non-VFR conditions as stratus and -DZ continue off/on across the TAF sites. The good news, conditions will improve by the early-mid afternoon across the sites as well with pronounced dry slot moving in. Expect VFR conditions to return by around 20z at the metro sites KIXD/KMKC/KMCI, likely in that order. KSTJ may hang onto IFR/MVFR conditions into late afternoon before going full VFR. Southerly winds will gust to around 20kts at times, slowly turning SW and W through the period. && .EAX WATCHES/WARNINGS/ADVISORIES... MO...None. KS...None. && $$ DISCUSSION...Curtis AVIATION...Curtis
