THE INSTABILITY.
CLOSED UPPER LOW CONTINUES ITS WOBBLE TO THE SOUTHEAST AS DOES THE
SURFACE LOW AND WILL SEE PRESSURE RISES INTO TONIGHT. FLOW WILL
REMAIN OUT OF THE NORTH NORTHEAST...WHICH WILL LIKELY KEEP A LOW
STRATUS DECK IN PLAY TONIGHT. THIS SHOULD LIMIT ANY VALLEY FOG
DEVELOPMENT AND HAVE LARGELY REMOVED THAT FROM THE FORECAST.
STRATUS DECK SHOULD LIFT AND DISSOLVE WITH THE MIXING OF THE DAY
MONDAY...AND LARGELY HAVE A MOSTLY SUNNY DAY IN THE FORECAST. A
COOLER AIRMASS WILL BE IN PLACE BY MONDAY MORNING AS EVIDENCED BY
