DRY AIR WORKING IN QUICKLY THIS MORNING HAS KILLED ANY FOG. SOME LINGERING CI AND CU/SC WILL THIN OUT OVER THE NEXT FEW HOURS. THEN SOME ADDITIONAL SCT CU COULD DEVELOP THIS AFTERNOON. SOME GUSTY WINDS MAYBE POSSIBLE WITH GUSTS INTO THE UPPER TEENS. SKIES WILL CLEAR OVERNIGHT. WITH THE DRY AIR...MOST TAFS WILL SEE NO FOG. THERE IS A POSSIBILITY AT LUK FOR SOME MVFR FOG TOWARD SURISE TOMORROW...BUT THINK THE CHANCE IS LOW ENOUGH AT THIS TIME TO LEAVE OUT. OUTLOOK...NO SIGNIFICANT WEATHER IS EXPECTED AT THIS TIME.
