Mesoscale Discussion 1966
NWS Storm Prediction Center Norman OK
0839 PM CDT Tue Aug 20 2024
Areas affected...Southeastern Colorado
Concerning...Severe potential...Watch unlikely
Valid 210139Z - 210315Z
Probability of Watch Issuance...20 percent
SUMMARY...Severe thunderstorms capable of damaging winds are ongoing
across portions of southeastern Colorado.
DISCUSSION...Deep boundary-layer mixing across southeastern Colorado
has resulted in steep low-level lapse rates that support severe
outflow winds. A surging downdraft has been observed north of the
KPUX radar site, with 60-70 MPH winds 500 ft above radar level.
Other convective cells in the Marginal Risk area will be capable of
similar outflow surges over the next 1-2 hours, with some potential
for additional local enhancement of outflow winds where outflows
merge. This activity should gradually die off in the absence of
solar heating and in the presence of a stabilizing nocturnal
boundary layer.
