A WIND CHILL ADVISORY REMAINS IN EFFECT UNTIL NOON CST TODAY. 

NORTHWEST WINDS AT 5 TO 12 MPH WILL COMBINE WITH VERY COLD AIR
TEMPERATURES TO PRODUCE BITTERLY COLD WIND CHILLS OF 20 BELOW TO
30 BELOW ZERO THIS MORNING.

A WIND CHILL ADVISORY MEANS THAT VERY COLD AIR AND STRONG WINDS
WILL COMBINE TO GENERATE DANGEROUSLY LOW WIND CHILL VALUES. THIS
WILL RESULT IN FROST BITE AND LEAD TO HYPOTHERMIA IF PRECAUTIONS
ARE NOT TAKEN. IF YOU MUST VENTURE OUTDOORS...MAKE SURE YOU WEAR
A HAT AND GLOVES.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
332 AM CST FRI JAN 23 2009

.SHORT TERM...TODAY
BIG STORY FOR TODAY IS THE LEADING EDGE OF ARCTIC HIGH PRESSURE THAT
WILL BE SURGING SOUTHEAST ACROSS IOWA...REMINDING US THAT IT IS
STILL JANUARY. THE PRIMARY SURFACE COLD FRONT IS ALREADY EAST OF THE
AREA...BUT THE REAL SURGE OF COLD ADVECTION DOES NOT REALLY BEGIN
ACROSS THE NORTH UNTIL CLOSER TO SUNRISE...AND FARTHER SOUTH AFTER
NOON. 850 MB TEMPS GO FROM -6C TO +6C NORTH-SOUTH AT 12Z TO -18C TO
-8C AT 00Z. EXCEPT FOR ONLY A COUPLE OF DEGREES OR SO OF RISE ACROSS
THE SOUTH THIS MORNING...TEMPERATURES WILL BE FALLING THROUGH THE
DAY. NORTHWEST WINDS WILL BE BRISK AND GUSTY...MAKING IT FEEL EVEN
COLDER. WITH THE INITIAL SURGE...WIND SPEEDS WILL LIKELY EXCEED 30
MPH WITH GUSTS CLOSE TO 45 MPH EARLY THIS MORNING. HOWEVER...THE
DURATION OF SUCH SPEEDS SHOULD BE TOO SHORT TO WARRANT AN ADVISORY.
WIND CHILL VALUES BY LATE AFTERNOON ACROSS THE NORTH WILL BE -10F TO
-20F. WILL HAVE SHALLOW LAYER OF STRATOCU MOVING OVERHEAD FOR MUCH
OF THE DAY WITH NEARLY NEUTRAL OMEGA IN THAT LAYER...BUT AS CLOUD
TEMPS FALL BELOW -10C...SCATTERED FLURRIES SEEM A REASONABLE BET.

.LONG TERM...TONIGHT THROUGH THURSDAY
ARCTIC HIGH PRESSURE WILL BUILD DOWN THE NORTHERN PLAINS INTO THE
MISSOURI RIVER VALLEY TONIGHT. THIS WILL PRECLUDE SNOW CHANCES AND
RESULT IN SLOWLY DECREASING WIND SPEEDS AND CLOUD COVER...AS WELL AS
CONTINUED COLD AIR ADVECTION. MINIMUM TEMPS ARE DIFFICULT TO PIN
DOWN TONIGHT AS COLD AIR ADVECTION WILL BE CONTINUOUS YET THERE ARE
INDICATIONS THAT SOME MID/HIGH CLOUDS MAY DEVELOP IN NORTHWESTERN
IOWA AFTER MIDNIGHT...INHIBITING RADIATIONAL COOLING SOMEWHAT. HAVE
STUCK CLOSE TO THE PREVIOUS FORECAST FOR LOWS. THE COMBINATION OF
DRAMATICALLY LOWER TEMPERATURES AND NORTHWEST WINDS WILL PRODUCE
WIND CHILLS OF -20 TO -30 ACROSS THE NORTH...PROMPTING A WIND CHILL
ADVISORY FOR TONIGHT. IN OUR WEST CENTRAL COUNTIES A COMBINATION OF
LIGHTER WINDS AND SLIGHTLY HIGHER LOW TEMPERATURES KEEPS THEM A BIT
ABOVE ADVISORY CRITERIA IN THIS FORECAST...BUT THAT WILL BE
MONITORED DURING UPDATES TODAY.

AFTER A COLD BUT QUIET DAY SATURDAY WITH HIGH PRESSURE NEARBY...OUR
NEXT POTENTIAL WEATHER MAKER WILL TAKE SHAPE IN THE FORM OF LOW
PRESSURE IN THE LEE OF THE ROCKIES ON SATURDAY NIGHT. FOR SEVERAL
DAYS THERE HAVE BEEN INDICATIONS OF A WIDE BAND OF MOISTURE/PRECIP
SETTING UP JUST NORTH OF THE 850 MB WARM FRONT...HOWEVER THERE ARE
DISAGREEMENTS AMONG VARIOUS FORECAST MODELS REGARDING
WHERE...WHEN...AND TO WHAT EXTENT THIS WILL OCCUR. THE GFS CONTINUES
TO BE THE MOST BULLISH...WITH MOST OTHER MODELS BEING LOWER AND MORE
INTERMITTENT WITH QPFS. THERE ARE SEVERAL REASONS FOR THIS. ONE IS
THAT THE GFS IS MOISTENING THE ATMOSPHERE MUCH MORE QUICKLY THAN ITS
PEERS ON SATURDAY NIGHT. GIVEN THE MAGNITUDE OF DRY AIR THAT WILL BE
IN PLACE TO OVERCOME...THE GFS SEEMS MUCH TOO QUICK TO DO SO
CONSIDERING WE WILL BE IN ZONAL WEST NORTHWESTERLY FLOW. ANOTHER
REASON IS THAT THE GFS IS SLIGHTLY FURTHER NORTH AND CLOSER TO OUR
AREA WITH THE 850 MB WARM FRONT THAN THE OTHER MODELS. AND
FINALLY...GFS FORECAST SOUNDINGS FOR SUNDAY INTO SUNDAY NIGHT SHOW A
PERSISTENT NEARLY SATURATED DENDRITIC LAYER EXTENDING FROM THE
SURFACE TO AROUND 600 MB. NAM FORECAST SOUNDINGS ARE LESS OPTIMISTIC
WITH SMALL POCKETS OF DRY AIR IN THE PROFILE AND SLIGHTLY WARMER
TEMPERATURES IN SOME LAYERS. WITH LITTLE IN THE WAY OF FORCING WITH
THIS SYSTEM...AND MOST OF THE SNOW PRODUCED BY RELATIVELY WEAK AND
INTERMITTENT LIFT WITHIN A DEEP...MOIST...AND COLD ATMOSPHERE...A
HIGH POP/LOW QPF EVENT APPEARS MOST LIKELY. SNOW RATIOS WILL BE
HIGH...PROBABLY 20-25 TO 1 IN SOME LOCATIONS...BUT THE QPFS SHOULD
REMAIN LOW ENOUGH TO PREVENT SIGNIFICANT ACCUMULATIONS. HOWEVER...IF
THE PROFILES DO END UP CLOSER TO THE GFS ESTIMATION ANYWHERE THEN
THEY MAY RECEIVE SOMEWHAT HIGHER SNOWFALL AMOUNTS.

AS SURFACE HIGH PRESSURE BUILDS IN SNOW WILL COME TO AN END MONDAY
NIGHT. A WEAK MID-LEVEL TROUGH PASSING OVER COULD PROVIDE SOME
FLURRIES OR ISOLATED LIGHT SNOW SHOWERS...BUT MEASURABLE SNOW
APPEARS UNLIKELY. THE ECMWF MODEL HAD BEEN MUCH STRONGER WITH THIS
TROUGH PRODUCING A SURFACE CYCLONE ON THE 12Z RUN...BUT HAS CALMED
DOWN SIGNIFICANTLY ON THE 00Z RUN AND IS NOW IN LINE WITH OTHER
FORECAST MODELS. THE WEATHER SHOULD REMAIN UNEVENTFUL UNTIL
WEDNESDAY WHEN ANOTHER COLD FRONT COMES THROUGH PROVIDING A
REINFORCING SHOT OF COLDER AIR.

&&

.AVIATION...23/06Z
MENTIONED MVFR VIS FOR FOG AT MOST TAF SITES EXCEPT FOD AS WINDS
HAVE BEGUN TO INCREASE IN NORTHWEST IA.  HAVE BRIEF PERIOD OF LIFR
VIS AT ALO...BUT FOG SHOULD BEGIN TO LIFT BY 07Z. FROPA EXPECTED
BETWEEN 06Z/11Z WITH MVFR CIG ANTICIPATED MOST OF THE DAY FRIDAY.
STRONG NORTHWEST WINDS WILL PERSIST THROUGH THE ENTIRE TAF
PERIOD...BUT SHOULD SLOWLY RELAX TOWARDS THE END OF THE FORECAST
PACKAGE. CONFIDENCE WAS LOW TO MENTION ANY SNOW...BUT POTENTIAL IS
THERE FOR SOME BRIEF PERIODS OF LIGHT SNOW REDUCING VIS TO MVFR
CONDITIONS BETWEEN 12Z/21Z.
