Mesoscale Discussion 1708 NWS Storm Prediction Center Norman OK 0651 PM CDT Mon Oct 09 2017 Areas affected...Northeast OK...Southeast KS Concerning...Severe Thunderstorm Watch 499... Valid 092351Z - 100115Z The severe weather threat for Severe Thunderstorm Watch 499 continues. SUMMARY...Isolated hail will continue to be the primary threat with storms this evening. DISCUSSION...Scattered convection is beginning to mature along the advancing wind shift over northeast OK with lightning now detected with updrafts over Osage County. Frontal convection may gradually increase across northeast OK over the next few hours but overall intensity of this activity may struggle to produce more than isolated large hail. Latest MRMS data at times exhibits hail approaching 1" but mostly marginally severe. One reason may be that large-scale forcing for ascent lags this region considerably. In addition, the onset of boundary-layer cooling will result in updrafts becoming increasingly elevated in nature. Even so, some threat for isolated severe will continue for the next few hours. ..Darrow.. 10/09/2017 ...Please see www.spc.noaa.gov for graphic product...
