    Mesoscale Discussion 1734
    NWS Storm Prediction Center Norman OK
    0703 PM CDT Sun Sep 12 2021

    Areas affected...Eastern Colorado and western Kansas

    Concerning...Severe potential...Watch unlikely=20

    Valid 130003Z - 130130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...An isolated severe wind threat continues across eastern
    Colorado and may continue into western Kansas before weakening after
    sunset.

    DISCUSSION...A line of storms across Lincoln County has shown
    increasing intensity over the past hour as it moves into a more
    favorable airmass with MLCAPE in excess of 500 J/kg and decreasing
    inhibition per SPC mesoanalysis. Further support for the lowering
    CINH can be seen by the high based cumulus across eastern Colorado
    on visible satellite imagery. Very steep low and mid-level lapse
    rates will continue to support a severe wind threat with this
    activity, but the threat should start to wane after sunset as the
    boundary layer starts to significantly cool and CINH starts to
    increase once again.
