NWS Kansas City, MO wrote its last area forecast discussion before the first event at Apr 15, 12:27 PM CST, 3 hours 58 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 127 PM CDT Sat Apr 15 2023 .Discussion... Issued at 126 PM CDT SAT APR 15 2023 Key Messages: - Chance for strong to severe thunderstorms in central MO this afternoon. - Rain/snow mix possible along and north of US Highway 36 Sunday morning. - Unseasonably cool temperatures expected Sunday and Monday morning. ...Discussion... A combination of satellite imagery and radar have made it easy to track the location of the cold front moving through the CWA. As this front moves out of the northwest quadrant of MO, this will keep severe weather concerns relegated to central, southern, and eastern MO. Ahead of the front, clearing across central and the southwestern quadrant of MO has allowed for the environment to recharge after storms this morning as WAA and moist air advection continue feeding into our warm sector. Our surface low has also taken a farther track south that what we were anticipated yesterday, currently over west- central MO. This will places the southeast quadrant of our CWA in a favorable spot to receive our forecast area's strongest storms. However, if the cold front makes it to the SE border of our CWA, SGF and LSX will be the one seeing all the severe storms this afternoon. As the front pushes east, storms will continue initiating around through 2PM as the boundary destabilizes. CAMs continue to resolve this first bout of storms to be isolated supercells before converging into a linear structure. These early afternoon storms will be surface-based, tapping into a decent pool of SBCAPE anywhere between 1500-2500 J/kg. Steep low-level lapse rates and effective bulk shear between 40-50 knots will be enough to support the development of supercells. All hazards are possible with these initial storms: a few tornadoes are possible with a good chance for large hail and damaging winds. Within a couple of hours, we anticipate these cells to converge in a linear structure as they make their way in central MO. Between 5PM-7PM, this line will be nearing the EAX CWA border and entering into LSX's CWA. The threat for severe weather in our CWA is anticipated to be completely done around 7PM tonight. Lingering showers and a few non-severe thunderstorms are possible for the rest of our CWA this afternoon into early Sunday morning. Behind the front, temperatures will drop into the mid 30s to lower 40s. We are still looking as a chance for a rain/snow mix to affect areas north of Interstate 70. While surface temperatures will sit a few degrees above freezing in northern MO, wet bulb temperatures may hover around freezing to 34 degrees F for a couple of hours Sunday morning. This coupled with saturated DGZ zones in the atmospheric profile and some hinting of weak frontogenesis fields at 700mb, the atmosphere may be primed and ready to go for some rain/snow showers. The extremely warm ground temperatures from our several days of 80 degree highs will keep any snow accumulation from occurring, if snow does end up occurring. By Sunday afternoon, dry weather will finally arrive with highs in the 40s to 50s. Temperatures will rebound back to seasonal normals in the 60s by Monday. Upper-level ridging will keep our weather dry and warm through through most of Monday and Tuesday until another upper-level shortwave trough digs into the Great Plains. Chances for rain and storms return Wednesday through the weekend. && .Aviation...(For the 18Z TAFS through 18Z Sunday Afternoon) Issued at 1219 PM CDT SAT APR 15 2023 MVFR conditions expected for the majority of the TAF period as broken to overcast clouds between 1000-2500 feet affect our terminal airspace. Rain will likely start up again around 3-4pm this afternoon, tapering off by the evening hours. We may see some IFR conditions with these showers, and will adjust accordingly as needed. Winds will be mainly out of the northwest, gusting through the evening hours around 25-30 knots, calming down around 10-13 knots overnight, and beginning to gust upwards of 30-35 knots by late Sunday morning. The severe threat for our terminals is non-existent today with the main bout of rain ending this evening. However, lingering light showers will be possible through Sunday morning potentially resulting in some VCSH in later prevailing groups. We have kept them out of our TAFs at this time until confidence is higher. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...Klaus Aviation...Klaus
