864 FXUS63 KTOP 222019 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 219 PM CST Wed Jan 22 2025 .KEY MESSAGES... - Cold front moves through tonight keeping temps on Thursday below freezing. - Dry weather with temperatures near or slightly below normal are expected through the weekend. && .DISCUSSION... Issued at 219 PM CST Wed Jan 22 2025 At mid afternoon, a couple of waves were moving through a mid level trough across the northern and central Plains. The northern wave was moving across Minnesota into the Dakotas while another was present over eastern Nebraska. Regional radar was pockets of showers/snow showers across parts of central and eastern Nebraska at 1945Z within an area of DPVA and steepening low and mid level lapse rates. For tonight, isolated sprinkles or flurries will be possible across the northern counties late this afternoon into the evening hours as the energy rotates southward into northeast Kansas. A cold front will continue to move through the forecast area this afternoon with the best advection of cold air arriving later this evening. This will send temperatures back into the teens for lows tonight. On Thursday, temperatures will cool back into the 20s for highs. A secondary mid level trough will move through Nebraska on Thursday with no precipitation expected. Temperatures rebound on Friday and warm to above freezing across northeast Kansas as warm advection commences Thursday night and continues through the day on Friday. Heights rise through the day on Friday as mid level flow transitions from northwest to a more westerly zonal flow. Kansas remains in a nearly Zonal flow through the weekend as a mid level low develops in the west and northern stream trough remains in Canada and into the northeast. Highs remain in the 30s for the weekend for highs , then warm into the 40s for the first half of next week as the upper low moves across the Rockies with ridging into the southern and central Plains. Forecast confidence for precipitation by next Wednesday remains low as models differ on the location and depiction of the mid level trough and associated energy and moisture return. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
