Mesoscale Discussion 1386
NWS Storm Prediction Center Norman OK
0312 PM CDT Mon Aug 03 2020
Areas affected...central/southern Wyoming...much of Colorado...and
northern/northeastern New Mexico
Concerning...Severe potential...Watch unlikely
Valid 032012Z - 032145Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated to scattered thunderstorms will pose a risk of
gusty winds approaching severe thresholds this afternoon and
evening. A WW issuance is not anticipated due to the isolated
nature of the threat.
DISCUSSION...Recent radar/satellite imagery indicates development of
convection initially along higher terrain across the discussion area
this afternoon. Though the storms have initially developed in areas
containing a relatively dry boundary layer, the combination of
modest low-level upslope flow beneath roughly 30 knots of
north-northwesterly mid-level flow will allow for propagation of
initial convection into lower-terrain areas where steep mid-level
lapse rates (8.5C/km) will allow for a risk of damaging wind gusts
and hail. A slightly higher risk for damaging wind gusts will
develop with any storms that can organize into linear segments and
propagate southward, though the overall risk should remain isolated
enough to preclude a WW issuance through the evening hours.
