Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0736 PM CDT Fri Sep 06 2019 Valid 070100Z - 071200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS THROUGH MID EVENING ACROSS PARTS OF THE CENTRAL HIGH PLAINS... ...SUMMARY... Strong storms could still pose at least some risk for severe hail and wind across parts of eastern Wyoming into mid evening. ...01Z Outlook Update... Strong convection lingers within weak surface troughing north through east of the Laramie mountains. This includes a small cluster of storms north of Douglas WY, which may be supported by forcing associated with a locally enhanced area of warm advection. Beneath 30-40 kt west-southwesterly 500 mb flow, deep layer shear across eastern Wyoming is strong, and boundary layer instability may remain sufficient to maintain at least some severe hail/wind risk into the 01-03Z time frame. Overnight, a broader area of lower/mid tropospheric warm advection may maintain thunderstorm development eastward through portions of western and central South Dakota and Nebraska, before diminishing. Otherwise, a couple of strong storms may linger through mid evening across parts of the northern intermountain region and Great Basin. However, due to increasingly sparse coverage, severe weather potential is becoming increasingly negligible. ..Kerr.. 09/07/2019Read more
