A Flood Watch has been issued for Saturday night into Monday as anticipated heavy rain falls on regions that recently received excessive rains. - The unsetteled pattern continues with additional storm chances mid to late next week. && .SHORT TERM /THROUGH SATURDAY NIGHT/... Issued at 301 PM CDT Fri Apr 26 2024 Atmosphere to remain unsettled through much of the short term as a negatively tilted upper low moves into Iowa and associated diffluence aloft aids upper vertical motion. Despite cloud debris from an MCS that formed over Oklahoma and spread across the forecast area today...elevated convection continues to form upstream of the Ozarks under the cloud cover. 18z KSGF RAOB depicting significant CIN with model soundings depicting even less instability farther east...thus severe threat to be limited Highway 65 east. Farther west...sunshine will support destabilizaton over southeast Kansas with storms forming southeast of ICT suggestive of the beginnings of the next round of storms. Leaned on the ML CAPE from the HREF and HRRR to however anticipate that any storms that may form to have a tough time propagating much into western Missouri this evening. Before then however hail to the size of tennis balls and damaging winds will be the primary threat for the storms that reach far southeast Kansas. The tornado threat will be somewhat reduced by veering surface winds and diminishing instability but the threat will need to be monitored. Rain chances will diminish this evening with minimal support for much of the day Saturday before diffluence induced uplift increases once again as the next waves moves across the Plains Saturday night. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Issued at 301 PM CDT Fri Apr 26 2024 Precipital water that had increased to around 1.3 Thursday before dropping to 0.8 inches on the 18z SGF RAOB, will once again surge northward to over 1.75 ahead of the next wave compliments of a 50 knot north orientated low level jet Saturday night. The resultant rainfall coupled with it falling on grounds already impacted by recent excessive rains raises an elevated to significant flood threat into Sunday. The next western wave will be more progressive as it tracks eastward along the Canadian border on Tuesday. Questions exists on how far south its influence will extend though moisture convergence along an attendant cold front will be enough to offer a limited potential for additional thunderstorms as it slowly sags southward late in the work week. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 1240 PM CDT Fri Apr 26 2024 Atmosphere to remain in an unstable pattern through the weekend.
