NZUS43 KTOP 121816 WRKTOP 130 PM Mar 12 2026 Strong west-northwest mid level flow was noted across the western and central CONUS. A deep lee surface trough across eastern CO/western KS, combined with deep mixing, was causing south- southwest winds of 30 to 40 MPH with gust of 40 to near 50 MPH. The strong surface winds and gusts will continue through the afternoon hours for much of the central and northern counties of the CWA. Therefore, the wind advisory will continue through 7 PM. This evening, the low-level jet will increase to around 50 KTS across the central and eastern counties of the CWA. The stronger low- level jet of 60 KTS will develop northeast of the CWA across east central KS and western MO. At this time it looks as if wind gusts of 35 to 40 KTS may develop across the northeast counties through the evening hours but there is some question to how widespread the stronger wind gusts will be across the northeast counties. Not sure if we will keep the dry adiabatic lapse rates after sunset which may constrain momentum transfers down to the surface. The evening shift will need to monitor the LLJ and how much parcel momentum transfer will occur to get wind gusts above 45 MPH. There is a chance that a wind advisory may be needed for the eastern and north central CWA counties this evening, once the wind advisory for the central and western counties expire. The weak surface front will become stationary along the OK?KS border on Friday. night temperatures on Friday will reach the lower 60s north to mid 60s south. Saturday, the mid level flow will become zonal and a lee surface trough will deepen across western NE/eastern CO. The front across northern OK will undergo frontolysis as it shift north. Winds will become southeast and southerly. Wind speeds will increase during the late afternoon and evening to 10 to 20 MPH with some gusts. Highs will warm into the mid to upper 70s across the western counties with mid 70s elsewhere across the CWA. Big changes are in store for the second half of the weekend. An H5 trough across the Pacific northwest will dig Southeast across the Plains and amplify Sunday. Strong low-level CAA across the northern Plains will send modified arctic air southward across the central and southern Plains. Highs on Sunday will be during the 12Z-15Z time period as the front rapidly shifts southward across the CWA. Temperatures may start out in the lower to mid 40s northwest and mid 50s to around 60s south but temperatures will fall through the 30s into the mid to upper 20s northwest and through the 40s into the mid 30s across the remainder of the CWA. Gusty northwest winds will make it feel even colder. The stronger ascent ahead of the amplifying trough will be northeast and east of the CWA but there may be enough ascent and frontogenesis for rainshowers that will become mix with and change over to snow showers through the afternoon hours into the early evening before ending. At this time any snow accumulations will be a dusting on grassy surface. Road surface temperatures will be warm. If you have any tender plants outdoors they will need to be taken in Sunday night, since overnight lows will drop into the mid to upper teens. Monday will continue to be cold as the center of the surface ridge of high pressure shifts southeast across eastern KS into the lower MS River Valley. Highs across the eastern counties will only reach the mid to upper 30s. Highs in the western counties will be warmer with highs in the mid to upper 40s. Tuesday through Thursday, expect a warming trend as an H5 ridge across the western US slowly shifts east towards the high Plains. The mid level flow will back from the north-norwest to the west northwest and surface winds will become southerly. Highs Tuesday will warm into the mid 50s to lower 60s southwest, highs on Wednesday will reach the lower 70s east to upper 70s west, and by Thursday, highs will reach the lower to mid 80s.
