08Z water vapor satellite had a mid level trough over western Utah and Arizona while profilers suggest the presence of a few downstream perturbations moving into western Kansas and Oklahoma this morning. Additional storms may form across the northern counties near and north of the warm front. Forecast soundings and hodographs continue to suggest the area near the triple point in central Kansas will have the higher probability of tornadoes into the early evening hours with discrete convection. Areas near and north of the warm front are likely to see the highest rainfall amounts and an increased potential for isolated flash flooding. Highs today are expected to top out in the mid 80s near central Kansas to the lower 70s in far northeast Kansas. Temperatures will be cooler in the 50s and 60s in the wake of the cold front.
