Mesoscale Discussion 0188
NWS Storm Prediction Center Norman OK
1205 PM CST Fri Feb 24 2023
Areas affected...Interior Santa Barbra County Interior
Mountains...Los Angeles County Mountains...and Ventura County
Mountains
Concerning...Blizzard
Valid 241805Z - 242200Z
SUMMARY...Heavy snowfall with rates exceeding 2 in/hr possible
through the afternoon and evening. Blizzard conditions possible at
times with near zero visibility.
DISCUSSION...A low currently located off the coast of California
continues to bring increasing mid-level moisture inland across
Southern California across the axis of a strong 40 kt low-level jet.
As the upper-level low advances eastward through the afternoon and
evening, colder air will overspread the region with lapse rates
steepening to around 6-6.5 C/km ahead of the frontal band. With
destabilization and increasing frontal forcing, expect an increase
in snowfall rates across the Santa Barbra Interior Mountains, Los
Angeles County, and Ventura County Mountains through the afternoon
and evening, with snowfall rates exceeding 2"/hr across the mountain
passes. Sustained winds of 30-40 mph with gusts 55-70 mph (locally
higher) will allow for blowing snow and reduced visibility. Blizzard
conditions will be possible, with near white-out conditions and
dangerous travel likely.
