A VERY MOIST BOUNDARY LAYER CHARACTERIZED BY MID/UPPER 70S SURFACE
DEW POINTS HAS BECOME MODERATELY UNSTABLE WITH HEATING. LATEST RUC
GUIDANCE SUGGESTS THAT MIXED LAYER CAPE IS NOW IN EXCESS OF 2000
J/KG...WHERE LOW-LEVEL CONVERGENCE HAS BECOME FOCUSED INLAND OF
SOUTHWESTERN COASTAL AREAS. SCATTERED STORM DEVELOPMENT IS NOW
UNDERWAY...AND SIGNIFICANT FURTHER INCREASE IN ACTIVITY AND
INTENSIFICATION APPEARS POSSIBLE THROUGH 21-23Z. AS CONSOLIDATION
AND UPSCALE GROWTH OCCURS...LIGHT EAST NORTHEASTERLY STEERING FLOW
WILL SUPPORT PROPAGATION TOWARD SOUTHWEST COASTAL AREAS... WHERE
TEMPERATURES ARE IN THE LOWER 90S. HEAVY PRECIPITATION LOADING MAY
CONTRIBUTE TO SPORADIC DOWNBURSTS...BEFORE GUSTY WINDS APPROACHING
SEVERE LIMITS PERHAPS BECOMES MORE COMMON ON THE LEADING EDGE OF THE
WESTWARD ADVANCING SURFACE OUTFLOW.
