Area forecast discussion, Apr 28, 3:52 PM CDT, 1 hour 1 minute before
Area Forecast Discussion National Weather Service Wichita KS 352 PM CDT Wed Apr 28 2021 .SHORT TERM...(This evening through Sunday night) Issued at 344 PM CDT Wed Apr 28 2021 The main concern through is the threat for strong to marginally severe storms through the remainder of the afternoon and evening along and ahead of the sfc cold front steadily moving through the area. As of 1945Z the cold front bisects the area in a line from about Emporia KS to just west of Winfield KS. Ample bulk shear running parallel to the cold front will continue to support broken lines of convection as it continues to move southeast this afternoon and evening. Overall, storms have been under-performing model progged MLCAPE so far today, likely due to extensive cloud cover/lack of destabilization across the area. The strongest storms that can develop may be able to support some dime to isolated quarter size hail as HiRes data continues to paint a small region of 1000-1500 J/kg CAPE along/just ahead of the front. In this same region, there is also a focused zone of about 100-150 J/kg 0-3km MLCAPE with increased sfc vorticity and LCLs in 500-700m AGL range. This combination has produced (northern OK), and will continue to support, a brief funnel cloud or two with updrafts along and just ahead of the front. The risk of a landspout tornado is very low but non-zero. A few additional showers and isolated storms will be possible along the 850-700mb baroclinic zone behind the sfc front however moisture becomes decreased in these areas thus expect a general taper-down in activity toward the late evening hours with just a few lingering elevated showers possible across far southeast KS around midnight. As the main trough continues to push east of the area tomorrow upper northwest flow will return to the region while sfc high pressure builds into the area. Weak upper ridging is progged to remain overhead through much of the weekend brining warm and dry conditions back across the area with temps in the mid 70s to low 80s. Meanwhile the 500mb low is progged to continue to meander across the eastern dessert southwest/northern Mexico through Saturday before it is forced northeast across Texas due to the next shortwave diving south of the pacific northwest. There is some consensus that the passing system brings some showers to the area Sunday evening and night. .LONG TERM...(Monday through Wednesday) Issued at 344 PM CDT Wed Apr 28 2021 As the pacific northwest trough continues its trek southeast, it should be located near the central Rockies by late Monday and ejecting out over the Central Plains by Tuesday. This will drive a cold front/developing sfc low across the region brining increased chances of showers and storms to the region. A big western CONUS ridge will be building to end the period, returning northwest flow to the region with dry condition and seasonable high temps. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 1255 PM CDT Wed Apr 28 2021 A southward moving frontal boundary is currently located from KHUT to near KEMP to KTOP. As the front moves south for the afternoon hours expect a wind shift to the NW, with the frontal boundary making it into SE KS by this evening. Copious amounts of moisture is located ahead of the front with MVFR cigs. Also seeing some scattered showers and storms developing ahead of the front as well, so plan on going with a VCTS for the KICT/KHUT and KCNU tafs as afternoon heating leads to additional TSRA development ahead of the front for the afternoon hours. As the front moves south, post frontal MVFR to IFR cigs will be common with some scattered showers around. So will go with a VCSH for this shower chance. Ketcham && .FIRE WEATHER...
