Area Forecast Discussion National Weather Service Wichita KS 653 AM CDT Fri Sep 17 2021 .SHORT TERM...(Today through Sunday night) Issued at 246 AM CDT Fri Sep 17 2021 An upper trof moving along the north central conus/Canadian border this morning will move to Ontario and the northern Great Lakes by early evening. The associated surface cold front will sag southward across central Kansas this afternoon with temperatures falling from midday highs in the 80s into the 70s. Much warmer air will reside further south across southern Kansas with highs near 90F. Some elevated convection is expected later this morning across central Kansas with some southward development into south central Kansas during the afternoon. The afternoon activity may become quasi-surface based where MLCAPE values greater than 1000 j/kg will reside along/just south of the front in the presence of weak deep layer shear. So a few strong storms will be possible, though risk for severe appears rather low. Upper ridging will develop over the area once again on Saturday with highs close to 90F across most of the area. An significant upper trof will move into the western conus on Sunday before moving over the northern and central Rockies Sunday night. It will remain unseasonably warm on Sunday with a bit more wind from the south across central Kansas. Darmofal .LONG TERM...(Monday through Thursday) Issued at 246 AM CDT Fri Sep 17 2021 The long awaited taste of Fall still looks to arrive Monday night and Tuesday as a modified Canadian/Pacific airmass plunges south across the central conus. The associated upper trof will slide eastward from the Plains to the Great Lakes and Ohio Valley on Wednesday. So the trend toward significantly cooler looks on track with temperatures below seasonal climo thru mid-week. KED && .AVIATION...(For the 12Z TAFS through 12Z Saturday morning) Issued at 630 AM CDT Fri Sep 17 2021 A cold front continues to approach central KS this morning, with a southward moving outflow boundary just ahead of the main front. Scattered convection along and just ahead of the front will continue to bring chances of VCTS/TSRA to the area today. Mentioned VCTS for the central KS sites and KHUT where confidence was highest. Central KS sites could see some brief lower cigs this afternoon behind the front. Additional elevated convection may develop over the next couple hours this morning, mainly west of I-135. A region of accas can be seen on satellite imagery though in a narrow swath. Given narrow axis opted to not include an earlier mention of storms for now, but will amend as needed. && .PRELIMINARY POINT TEMPS/POPS...
