MODELS IN GENERAL AGREEMENT NEXT 36 HOURS WITH NGM AND AVN BEING A LITTLE MORE AGRESSIVE IN MOVING CUTOFF LOW OVER BAHA PENINSULA EASTWARD...HENCE HIGHER POPS ON THURSDAY. OUTSIDE SLIGHT CHANCES LATE THIS AFTERNOON AND EARLY EVENING DUE TO FRONTAL BOUNDARY AND OROGRAPHIC LIFTING OVER MOUNTAINS...BELIEVE MODELS MAY BE A LITTLE TOO FAST ON APPROACH OF AFOREMENTIONED CUTOFF LOW SO WILL LEAN TOWARDS A LESSER CHANCE OF POPS GIVEN MORE STABLE AIR BEHIND FRONTAL BOUNDARY.
