...SYNOPSIS...
FAST ZONAL FLOW WILL COVER THE SRN HALF OF THE NATION THIS FORECAST
PERIOD BETWEEN WEST COAST/NRN GREAT BASIN TROUGH AND BROAD
SUBTROPICAL RIDGE ACROSS THE SRN GULF OF MEXICO/BAY OF CAMPECHE.
DOWNSTREAM FROM THE POSITIVE TILT WRN TROUGH...FROM THE NRN HIGH
PLAINS EWD TO THE UPPER MS VALLEY...DEEP LAYER NLY FLOW EMANATING
FROM THE POLAR REGIONS MERGES WITH ZONAL AIR STREAM TO MAINTAIN 
STRONG MID LEVEL CONFLUENCE AND LARGE SCALE SUBSIDENCE FROM THE
PLAINS TO THE MIDWEST.

...CA COAST...
CONVECTIVE SHOWERS SHOULD INCREASE WITHIN TROUGH AXIS...AND NEAR MID
LEVEL COLD POOL...DRIFTING SEWD ACROSS CA AND NV LATER TODAY.
HOWEVER...COOL AND RELATIVELY DRY BOUNDARY LAYER WILL LIMIT BUOYANCY
ACROSS MOST OF THE REGION. MARINE LAYER MAY CONTRIBUTE TO SLIGHTLY
GREATER POTENTIAL INSTABILITY NEAR THE CNTRL CA COAST DURING THE
AFTERNOON AS A SMALL SCALE PERTURBATION ROTATES THROUGH THE BASE OF
THE LARGER SCALE TROUGH FROM SFO SWD. ONLY A COUPLE OF ISOLATED CG
LIGHTNING STRIKES OCCURRED DURING A SIMILAR SCENARIO ON FRIDAY
AFTERNOON AND A GENERAL TSTM FORECAST AREA DOES NOT APPEAR WARRANTED
FOR TODAY.
