VFR CONDITIONS WILL CONTINUE THROUGH TONIGHT INTO THE MID
MORNING HOURS CONFIDENTLY, WITH COLD NORTH TO NORTHWEST WINDS A
LITTLE UNDER 10 KTS. BY MID MORNING, SOME MODELS SUGGEST A MVFR

MODELS SUGGESTING LOW CLOUDS, ALSO HAVE LOW CLOUDS IN PLACE NOW,
WHICH IS NOT HAPPENING. I HAVE GENERALLY LOWERED CIGS TO LOWER
END VFR, WITH A SCATTERED 3000 FT LAYER AS THE POTENTIAL IS NOW
