Mesoscale Discussion 1422
NWS Storm Prediction Center Norman OK
0241 PM CDT Tue Jul 04 2023
Areas affected...much of northern and eastern Colorado...southern
Wyoming
Concerning...Severe potential...Severe Thunderstorm Watch likely
Valid 041941Z - 042045Z
Probability of Watch Issuance...80 percent
SUMMARY...Storms will increase in coverage from southern Wyoming and
northern Colorado across much of eastern Colorado, with damaging
outflow winds and area of hail.
DISCUSSION...Storms are gradually increasing along the Front Range,
while heating continues to destabilize the air mass. Northeasterly
surface winds will maintain low-level moisture with CAPE values
gradually increasing this afternoon. The northeasterly surface winds
beneath midlevel westerlies of 40-50 kt are resulting in favorable
hodographs for cellular storm mode, and this should eventually
enhance hail potential. With time, increasing outflows are expected
to merge and surge east across eastern CO and eventually western KS
where a well-heated boundary layer awaits.
