AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
320 AM CST SAT DEC 20 2008

.SHORT TERM...TODAY
INVERTED SFC TROUGH EXTENDS FROM LOW IN WESTERN KS UP THE GREAT
PLAINS AT THIS HOUR...WITH A 500 MB LOW APPROACHING FROM SOUTHERN
CANADA. AS THE MID-LEVEL LOW MOVES INTO NORTH DAKOTA THROUGH THE DAY
THE SFC TROUGH WILL BE PUSHED EASTWARD...WITH GOOD LIFT AND MOISTURE
PRODUCING SNOW OVER THE UPPER MIDWEST. BULK OF THE SNOW IN OUR AREA
WILL BE ACROSS THE NORTH...WITH LIGHTER AMOUNTS CENTRAL AND SOUTH.
MORE SIGNIFICANTLY...AN ARCTIC HIGH SPILLING OVER THE HIGH PLAINS
AND INTO THE MIDWEST THIS AFTERNOON WILL RESULT IN A WIND SURGE ON
THE BACK SIDE OF THE INVERTED TROUGH...HAVING THE SENSIBLE EFFECT OF
A COLD FRONT WITH A GOOD PUSH OF WIND BEHIND IT. BETWEEN THE 2 TO 4
INCHES OF SNOW THAT WILL FALL ACROSS THE NORTH TODAY AND THE 7 TO 12
INCHES THAT WAS RECEIVED IN THE SAME AREA THURSDAY NIGHT/FRIDAY
MORNING...THERE WILL BE A LOT OF SNOW TO BLOW AROUND ONCE THE WINDS
PICK UP DURING THE MID/LATE AFTERNOON HOURS. BECAUSE EXPECTED NEW
SNOW AMOUNTS ARE BELOW WARNING CRITERIA AND LOWERED VSBYS IN BLOWING
SNOW ARE NOT EXPECTED TO BE PREVAILING 1/4SM OR LESS...HAVE OPTED TO
ISSUE A WINTER WEATHER ADVISORY FOR THE NORTH/NORTHWEST TODAY. WHILE
BLIZZARD CONDITIONS ARE POSSIBLE IN THIS AREA BEFORE 00Z...IT IS
LIKELY THAT THEY WILL NOT BE WIDESPREAD. AS FAR AS THE BEGINNING
TIME OF THE ADVISORY IT IS SOMEWHAT ARBITRARY BECAUSE SNOW WILL BE
BEGINNING IN OUR NORTHWEST WITHIN THE NEXT COUPLE OF HOURS...BUT IT
WILL BE LIGHT AND NOT BEGIN TO ACCUMULATE APPRECIABLY UNTIL LATER IN
THE MORNING...WITH THE WIND SURGE/BLOWING SNOW NOT COMING INTO PLAY
UNTIL AFTER NOON. WILL TAKE A KIND OF MIDDLE GROUND BETWEEN THESE
EFFECTS WITH AN ADVISORY BEGINNING AT 9 AM. THAT WILL GIVE PEOPLE A
COUPLE OF HOURS TO GET AROUND WHILE THE SNOW AND WINDS ARE
RELATIVELY LIGHT BEFORE THE ADVISORY KICKS IN. CONDITIONS WILL
WORSEN TONIGHT AS TEMPERATURES PLUMMET AND WINDS GRADUALLY INCREASE
FURTHER AND OVER A WIDER AREA.

.LONG TERM...TONIGHT THRU FRIDAY
ANY SNOWFALL WL TAPER OFF TO FLURRIES AND/OR A FEW SNOW SHOWERS THIS
EVENING AS FORCING PASSES TO THE EAST.  INITIAL SURGE OF COLD AIR
BEHIND FRONT WL SEE FIRST SURGE OF WINDS ACRS THE CWA.  MAY SEE A
LULL IN THE VERY STRONG WINDS FOR A PERIOD THIS EVENING WITH
CONDITIONS NOT AS BAD.  HOWEVER...A SECONDARY SURGE OF ARCTIC AIR WL
PUSH IN LATE TONIGHT INTO SUNDAY MORNING WITH VERY STRONG NORTHWEST
WINDS.  SOUNDINGS INDICATE A 3-4KFT MIXED LAYER WITH WINDS
INCREASING TO 50KTS+ AT TOP WITH 30-35KTS AT THE SFC BY 12Z ON
SUNDAY AT KMCW.  GIVEN THE FOOT OF SNOW IN NORTHERN IA ALONG WITH
THE NEW SNOW FROM TODAY AND THESE STRONG WINDS.  HAVE OPTED FOR A
BLIZZARD WARNING ACRS THE FAVORED FLAT/OPEN TERRAIN OF NORTH CENTRAL
IA TONIGHT INTO SUNDAY. EXPECT WORST CONDITIONS FROM 3 AM EARLY
SUNDAY MORNING TO 3 PM ON SUNDAY AFTERNOON WHEN WINDS SHOULD BE THE
STRONGEST.  VISIBILITIES LIKELY BE NEAR ZERO DURING THIS TIME WITH
SUBSTANTIAL DRIFTING OF SNOW ACRS HIGHWAYS WITH TRAVEL EXTREMELY
DIFFICULT IF NOT IMPOSSIBLE. WIND CHILLS WILL ALSO BE BITTERLY COLD
WITH VALUES FROM -25 TO -40 BELOW ZERO. JUST SOUTH AND EAST OF THIS
WARNING AREA...HAVE ISSUED A BLIZZARD WATCH.  THIS AREA WAS SOMEWHAT
OF A TRANSITION LOCATIONS FROM MIXED PCPN TO SNOW DURING THE LAST
STORM.  THERE IS GENERALLY 4 TO 6 INCHES OF SNOW COVER BUT IT IS A
BIT HEAVIER/CRUSTY.  REMAINDER OF CENTRAL AND SOUTHERN IA HAD
PRIMARILY FZRA/IP FROM LAST EVENT AND EXPECT LITTLE ADDITIONAL SNOW
TODAY...THEREFORE BLOWING SNOW MUCH MORE LIMITED.  HOWEVER...WIND
CHILLS WILL BE VERY COLD IN THESE LOCATIONS AND HAVE GONE WITH AN
ADVISORY FROM I80 CORRIDOR ON SOUTH FROM TONIGHT INTO SUNDAY FOR
PROLONGED PERIOD OF BITTERLY COLD WIND CHILLS.

THE WINDS ARE FORECAST TO BEGIN SUBSIDING ON SUNDAY EVENING AS HIGH
PRESSURE BUILDS INTO THE STATE.  TEMPS ON SUNDAY NIGHT WILL BE WELL
BELOW ZERO WITH MOST LOCATIONS FROM -10 TO -20 FOR AIR TEMPS AS
SKIES CLEAR AND WINDS SUBSIDE.  WL SEE WAA BEGIN ON MONDAY AS
SOUTHERLY WINDS DEVELOP IN RESPONSE TO INCREASING THICKNESSES AS
WESTERN TROF DEEPENS.  INITIAL SHORTWAVE ON MONDAY NIGHT ALONG WITH
STRONG LOW LEVEL JET AND INCREASING MOISTURE HELP TO PRODUCE SOME
LGT SNOW ACRS CNTRL/NORTHERN IA BY LATE MONDAY NIGHT.  THE THREAT OF
PCPN WL PERSIST INTO TUESDAY AND TUESDAY NIGHT AS SOUTHWEST FLOW
PERSIST AHEAD OF AN EJECTING SHORTWAVE.  SOME ACCUMULATING SNOWS MAY
ONCE AGAIN VISIT THE STATE...ESPECIALLY THE SOUTHEAST HALF.  LITTLE
CHANGE IN THE FORECAST BEYOND THIS POINT AS COLD WEATHER PERSISTS.

&&

.AVIATION...20/06Z
CIGS REMAIN MAINLY IN THE MVFR RANGE...WITH A FEW IFR OBSERVATIONS
ACROSS WESTERN SOUTHERN IOWA. EXPECT THE MVFR/LOCAL IFR CONDITIONS
TO CONTINUE THROUGH THE ENTIRE TAF PERIOD. UPPER LEVEL WAVE NEARING
THE AREA...WITH SNOW APPROACHING EASTERN SOUTH DAKOTA. THIS SNOW
WILL CONTINUE TO SPREAD EASTWARD IMPACTING MAINLY KFOD...KMCW...AND
KALO BY MID/LATE MORNING INTO THE AFTERNOON HOURS. CHANCE FOR BRIEF
PERIODS OF IFR/LIFR VSBYS WITH THE SNOW...WITH THE BEST CHANCE AT
KMCW SO HAVE INCLUDED A TEMPO GROUP FOR THOSE CONDITIONS THERE.
OTHERWISE BIG ISSUE WILL BE THE STRONG AND GUSTY NORTHWEST WINDS
EXPECTED BEHIND THE ARCTIC COLD FRONT BY THIS AFTERNOON INTO
TONIGHT. THIS WILL REDUCE VSBYS ACROSS THE NORTHERN TAF SITES WHERE
CONSIDERABLE AMOUNT OF SNOW FELL YESTERDAY AND THE NEW SNOW IS
EXPECTED. THEREFORE ANTICIPATE VSBYS DROPPING INTO THE IFR/LIFR
CATEGORY INTO TONIGHT...AND HAVE HIGHLIGHTED THIS WITH ONLY A 1SM
MENTION AT THIS TIME. HOWEVER IT IS HIGHLY LIKELY THAT NEAR BLIZZARD
CONDITIONS WILL BE PRESENT ACROSS NORTHERN IOWA...SO THE TAF SITES
MAY SEE VSBYS REDUCED TO A QUARTER MILE OR LESS AT TIMES SATURDAY
NIGHT.
