AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
612 AM CST MON FEB 11 2008

.DISCUSSION...
PRECIPITATION HAS ALREADY DEVELOPED ACROSS SOUTHEAST
KANSAS...NORTHWEST OKLAHOMA...AND SOUTHWEST MISSOURI...AND IS HEADED
TOWARD THE AREA.  ALL GUIDANCE HAS SETTLED DOWN ON A PRIMARILY
FREEZING RAIN/SLEET EVENT ACROSS SOUTHEAST MISSOURI...CHANGING TO
SLEET AND SNOW FURTHER NORTH INTO SOUTHWEST ILLINOIS...AND PRIMARILY
SNOW WITH SOME FREEZING DRIZZLE MIXED IN ALONG AND NORTH OF THE I-70
CORRIDOR.  HAVE CONVERTED THE REMAINDER OF THE WINTER STORM WATCH
OVER TO A WINTER WEATHER ADVISORY.  THINK SNOW AMOUNTS WILL FALL
SHORT OF ADVISORY CRITERIA ACROSS MUCH OF THE ADVISORY
AREA...HOWEVER...ALL MODEL SOUNDINGS ALONG THE I-70 CORRIDOR HINT AT
AN EXTENDED PERIOD OF FREEZING DRIZZLE AS THE LOWER AND MIDDLE
LAYERS WARM THROUGH THE DAY AND INTO THE EVENING DUE TO STRONG WARM
ADVECTION AND DIABATIC PROCESSES.  THIS REMOVES THE ICE CRYSTALS
FROM THE CLOUDS AND LEAVES SUPER COOLED WATER DROPLETS.
TEMPERATURES AT THIS TIME ARE PRIMARILY IN THE LOW TO MID TEENS
ACROSS THE ADVISORY AREA AND I DONT THINK SURFACE TEMPERATURES ARE
GOING TO GET ABOVE FREEZING TODAY...SO EVEN 2-5 HUNDREDTHS OF SUPER
COOLED DRIZZLE WILL FREEZE INSTANTLY TO UNTREATED SURFACES CAUSING
POTENTIALLY HAZARDOUS CONDITIONS ON ROADS.  AS THE LOW LEVEL JET
NOSES NORTHEAST INTO ILLINOIS TODAY...IT WILL RUN INTO PROGRESSIVELY
COLDER AIR.  WHILE SOUNDINGS ARE INDICATIVE OF FREEZING RAIN OVER
THE SOUTHEAST MISSOURI...OVER SOUTHERN ILLINOIS THEY ARE INDICATIVE
OF A SNOW/SLEET MIXTURE...ESPECIALLY THIS EVENING.  ITS A
BORDERLINE ADVISORY/WARNING SITUATION IN THE SALEM AREA FOR INSTANCE
WHERE SOUNDINGS ARE HINTING AT A 3-5 HOUR PERIOD OF SLEET.  IF THE
PRECIPITATION IS HEAVY ENOUGH WELL BE PUSHING OUR 1/2 INCH OF SLEET
WARNING CRITERIA OVER THERE.

ALL THIS ADDS UP TO A VERY COMPLEX FORECAST FOR THE NEXT 24 HOURS OR
SO...BASED PRIMARILY ON THE THERMAL PROFILES OF THE NAM.  AN ERROR
OF A FEW DEGREES OR A FEW MILES IN ANY DIRECTION WILL DRASTICALLY
ALTER THE WEATHER ACROSS THE AREA.

MANY THANKS TO SURROUNDING UFOS FOR THE COLLABORATION COORDINATION
ON THIS TRICKY FORECAST

.AVIATION...
FOR THE 12Z TAFS...
LEFT GOING FORECAST PRETTY MUCH ALONE WITH VFR CONDITIONS THIS
MORNING AND LOWERING CIGS DURING THE AFTERNOON AT ALL SITES.
STL/SUS/COU WILL BE ON THE NORTHERN EDGE OF THE PRECIP SHIELD WITH
UIN NOT SEEING MUCH PRECIP AT ALL. COUS PRECIP SHOULD REMAIN RATHER
LIGHT THROUGHOUT THE DAY. STL/SUS SHOULD SEE A BETTER CHANCE FOR
ACCUMULATING SNOW...ESPECIALLY LATE THIS AFTERNOON AND EARLY
EVENING. THIS IS ALSO THE BEST PERIOD FOR EXPERIENCING IFR VSBYS
WITH THIS SYSTEM. TEMPERATURES APPROACH THE FREEZING MARK ALOFT
AROUND 00Z...SO ADDED SLEET. THERE MAY BE A PERIOD OVERNIGHT OF
SOME FREEZING DRIZZLE AREA WIDE...BUT COU SHOULD SEE THE BEST
CHANCE OF A LIGHT GLAZING. CIGS WILL CONTINUE TO DECREASE
OVERNIGHT. A COLD FRONT WITH NORTHWESTERLY WINDS IS EXPECTED TO
PUSH THROUGH THE REGION TOWARDS DAWN...BUT DUE TO THE LENGTH OF
GOING FORECAST...DECIDED TO LEAVE IT FOR THE 18Z TAF SET.
