UPDATE
COMPLICATED WEATHER SITUATION ACROSS THE AREA THIS MORNING. HAVE
DECIDED TO ALLOW THE DENSE FOG ADVISORY TO EXPIRE...WITH ONLY ONE
LOCATION STILL REPORTING ONE QUARTER MILE VISIBILITY...AND ALL
OTHER SITES REPORTING A HALF MILE OR BETTER. THIS MAY BE SPLITTING
HAIRS...BUT THOSE ARE THE REQUIREMENTS. THE ONE SITE IS LIKELY TO
IMPROVE IN THE NEXT HOUR. WILL CONSIDER A NEW ADVISORY IF VSBYS
DROP AGAIN AS THE SURFACE LOW APPROACHES AND ENHANCES CONVERGENCE. PEOPLE
WILL STILL NEED TO BE CAUTIOUS OUT THERE TODAY...SO HAVE WORDED
THE EXPIRATION STATEMENT PRETTY HEAVILY.
AVIATION
AS FOR AVIATION...WE WILL REMAIN IN THE SOUP TODAY...WITH LIFR
CIGS AND LIFR/IFR VSBYS THROUGH THE CURRENT SET OF TAFS. THERE MAY
BE SOME IMPROVEMENT AFTER 12Z WEDNESDAY...BUT THAT WILL BE
TEMPORARY AS A NEW SYSTEM MOVES IN TO SOUP US IN AGAIN LATER WEDNESDAY.
DVN WATCHES/WARNINGS/ADVISORIES
IA...NONE.
IL...NONE.
MO...NONE.
