AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ST LOUIS MO
1122 AM CST FRI DEC 19 2008

.UPDATE...
/1121 AM CST FRI DEC 19 2008/
HAVE LET WIND ADVISORY EXPIRE ON TIME. ONLY A FEW LOCATIONS ARE
NEAR CRITERIA AT 17Z...AND PRESSURE GRADIENT WILL WEAKEN AS
SURFACE LOW OVER NORTHERN INDIANA MOVES QUICKLY EASTWARD THIS
AFTERNOON. HAVE INCREASED CLOUDS THROUGH TONIGHT BASED ON
SATELLITE AND OBSERVATIONS UPSTREAM. THERE IS SOME POTENTIAL FOR
SCATTERED FLURRIES OVER THE NORTHERN HALF OF THE CWA...BUT DO NOT
FEEL CHANGE IS HIGH ENOUGH TO INCLUDE IN FORECAST. ONLY MADE MINOR
CHANGES TO TEMPERATURES.

BRITT

&&

.DISCUSSION...
/506 AM CST FRI DEC 19 2008/

A DIFFERENT WX STORY TO HIT EACH DAY OVER THE NEXT FEW DAYS.

FOR TODAY...WE WILL BE SAYING GOODBYE TO OUR ICE STORM BUT DEALING
WITH SOME DEVELOPING FOG THIS MORNING AND BRINGING IN STRONG
WINDS IN THE STORM/S WAKE ALSO THIS MORNING. TEMPS WILL ALSO BE A
CHALLENGE GIVEN THE LARGE GRADIENT ACRS THE FA ATTM. PCPN DRY
SLOT HAS WORKED THRU THE FA...AND WILL GO OUT WITH A DRY
FCST...EFFECTIVELY BRINGING TO A CLOSE THE SIGNIFICANT ICE EVENT
OVER THE NRN THIRD OF THE FA WHERE A QUARTER TO THIRD OF AN INCH
OF ICE ACCRETION OCCURRED. THE DRY SLOT FOR THE CLOUDS ALSO
WORKING THRU THE FA...WITH A MORE PERMANENT CLEARING TO OCCUR THIS
MORNING FOR AREAS S OF I-70...AND MORE CLOUDS EXPECTED TO THE N.
VERY STRONG WINDS JUST OFF THE GROUND...CLOCKED AT 50-70KTS AND
GREATER ON VWP AND PROFILER NETWORK...WILL GAIN A BETTER ABILITY
TO MIX DOWN TO THE SFC AS STRONG LO PRES PASSES TO OUR N AND TURNS
WINDS TO THE SW AND W...AND SO SHOULD SEE NEAR WIND ADVSRY LEVELS
THIS MORNING WITH GUSTS TO 40MPH. TEMPS IN THE MID 50S SURGING
NEWD FROM SWRN MO SHOULD MAKE INROADS TO MUCH OF THE AREA S OF
I-70 BEFORE 12Z...WHEN CDFNT WILL THEN PUSH THRU THE FA AND BRING
TEMPS BACK DOWN AGAIN.

ON SATURDAY...WE WILL SEE A SMALL CHANCE FOR RAIN OR SNOW OVER THE
AREA WITH PASSAGE OF A STRONG COLD FRONT DURING THE AFTERNOON.
THIS FRONT WILL PROVE NO DIFFERENT THAN OTHER FRONTS THIS TIME OF
YEAR...WITH BEST PCPN CHCS ALG/BHND IT. VERTICAL TEMP PROFILES ON
MODELS SHOW P-TYPE SHOULD START OUT AS LIQUID FOR MOST AREAS BUT
THEN SWITCH TO SNOW...BUT THAT/S IF IT PRECIPITATES AT ALL.
MOISTURE WILL BE HARD TO COME BY WITH TODAY/S SYSTEM SCOURING OUT
MUCH OF THE GOOD MOISTURE FROM THE LOWER ATMOSPHERE AND LITTLE
TIME FOR RECOVERY IS ALLOWED. FOR NOW HAVE MAINTAINED THE TOKEN
30PCT CHCS IN THE FORECAST...ALTHOUGH IT IS LOOKING MORE DOUBTFUL.
THE REAL STORY WILL BE PASSAGE OF A STRONG CDFNT DURING THE
AFTERNOON...WITH THE TIMING LATE ENOUGH IN THE DAY AND THE BETTER
CAA LAGGING A BIT BEHIND TO PREVENT NON-DIURNAL TEMP WORDING IN
THE FORECAST. A FEW HRS BEHIND CD FROPA SHOULD SEE A MARKED INCR
IN WIND SPEEDS WITH STRONG PRES RISES AND TIGHT PRES/TEMP GRADIENT
INDICATED...WITH 15-25 MPH SUSTAINED EXPECTED WITH GUSTS TO
35-40MPH.

ON SUNDAY AND MONDAY...IT WILL ALL BE ABOUT THE BITTER COLD. MODELS
HAVE BEEN ADVERTISING THIS FOR A LONG TIME NOW...WITH 1037MB HI
CENTER TO COME DOWN EARLY NEXT WEEK. THIS AIRMASS LOOKS EVERY BIT
AS COLD AS THE ONE WE SAW EARLIER THIS WEEK...IF NOT COLDER...AND
SO HAVE FORECASTED TEMPS COMPARABLE TO THE EVENT FROM LAST
WEEK...WITH DAYTIME HIGHS GENERALLY FROM 10 TO 20 DEGREES BOTH
DAYS AND NIGHTTIME LOWS IN THE SINGLE DIGITS BELOW AND ABOVE ZERO.
COMBINED WITH THE WINDS...MAY SEE WIND CHILL ADVSRY CRITERIA BOTH
SUNDAY AND MONDAY MORNINGS...ESPECIALLY ACROSS THE NRN THIRD OF
THE FA.

TAKING A SNEAK PEEK AT THE EXTENDED...WE ARE STILL SLATED TO SEE
