Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1100 PM CST Sun Nov 07 2021
Valid 081200Z - 091200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Lightning may be noted with convection across northern California
later tonight, primarily after 03z.
...Northern CA...
An early-day short-wave trough is forecast to eject across CA into
the Great Basin, though meager moisture/instability will be noted
ahead of this feature. However later tonight, low-level warm
advection is expected to increase markedly across northern CA ahead
of a secondary stronger short-wave trough. Large-scale forcing for
ascent will contribute to mid-level moistening/destabilization as
favorable trajectories encourage PW values to increase to near one
inch. Forecast soundings suggest convection that forms will remain
elevated in nature, though parcel ascent should gradually lower to
near 850mb by the end of the period.
