VERY DEEP MARINE LYR IN PLACE FOR THIS TIME OF YEAR, 6000 FEET AT VBG
AND 3000 AT NKX. MUCH MORE LIKE A SPRING-TIME MARINE LYR THAN MID TO
LATE SUMMER. ONSHORE GRADIENTS ARE UP AS WELL AND THE COMBINATION OF
THESE TWO FACTORS SHOULD RESULT IN A COOLER DAY ACROSS THE AREA. TEMPS
MAY BE A TAD WARM IN THE ZONES GIVEN THE CURRENT CONDITIONS BUT ARE
CLOSE ENOUGH. SOUNDINGS CONFIRM WHAT WE SEE ON WATER VAPOR IMAGERY
WHICH IS A STRONG SOUTHWEST FLOW DEVELOPING ALOFT. AN UPPER TROF WITH
A VORT MAX RIGHT OFF THE CENTRAL COAST IS THE CULPRIT AND ALSO
RESPONSIBLE FOR OUR DEEP MARINE LYR. THIS WILL MOVE OUT BY SAT AND
ALLOW DAYTIME TEMPS TO INCREASE EACH OF THE NEXT FEW DAYS. IN
ADDITION, GRADIENTS ARE EXPECTED TO TREND OFFSHORE SO THIS WILL ALSO
HELP WARM TEMPS. AS A RESULT, WE SHOULD BE BACK TO NORMAL BY SUNDAY.
NO CONVECTION IS EXPECTED FOR THE NEXT SEVERAL DAYS.
