AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
317 PM CST FRI NOV 12 2010

...FIRST MAJOR WINTER STORM TO AFFECT PORTIONS OF CENTRAL IOWA...

.SHORT TERM /TONIGHT/...
COMPLEX FORECAST ON THE WAY FOR TONIGHT...THOUGH INITIALLY WET WITH
LIQUID CONDITIONS PREVAIL UNTIL MIDNIGHT. WEAK SFC LOW BEGINNING TO
FORM IN SOUTHEAST KS AND IS EXPECTED TO STRENGTHEN AS IT LIFTS TO
THE NORTH THIS EVENING. STRONG PUSH OF THETAE ADVECTION AND MOISTURE
WILL BE FORCED INTO AN INCREASINGLY FRONTOGENETICAL REGION ACROSS
THE WEST/NORTHWEST PORTION OF THE FORECAST AREA...WITH A PORTION OF
THE FAR NORTHWEST SEEING THE RAIN MIX AND THEN CHANGE TO SNOW AFTER
MIDNIGHT. BOTH THE EURO AND NAM HAVE SLOWED THE SYSTEM DOWN AS IT
CROSSES THE REGION LATE TONIGHT AND SATURDAY. THIS IS SIMILAR TO
SOME OF THE SOLNS EARLIER THIS WEEK BY THE GEM/EURO/AND NAM. AS THE
SYSTEM WRAPS UP...COLD AIR WILL BE PULLED INTO THE BACK SIDE AS
SNOWFALL CONTINUES. BUFKIT SOUNDINGS FROM KFRM SUGGEST ALL SNOW WITH
THICKNESS AND H850 TEMPERATURES SUPPORTING A CHANGE IN THE
NORTHWEST/NORTH CENTRAL DURING THE EVENING AND TOTAL CHANGEOVER
AFTER MIDNIGHT NORTHWEST/WEST.  LOOKING AT THE 1.5 PV SFC SHOWS A
NICE POTENTIAL VORTICITY ANOMALY CROSSING THE REGION OF GREATEST
SNOWFALL CONCERN OVERNIGHT AS A TROP FOLD TO ABOUT 500 MB OCCURS.
LOOKED QUICKLY AT PLANAR VIEW OF DENDRITIC LAYER AND OMEGA WHICH
SHOWS DECENT LIFT OVERNIGHT FROM 06 TO 12Z TIMEFRAME. CONCERNS ABOUT
SNOW RATIOS THE NEXT THING TO COME INTO PLAY. WITH THE TEMPERATURES
NEAR THE FREEZING MARK OVERNIGHT A RATIO OF 8 TO 10 IS MOST LIKELY
WHICH MAY KNOCK DOWN TOTALS A BIT. MODELS GENERATE QPF AMOUNTS OF 1
TO 1.2 INCHES OVERNIGHT WITH NEARLY HALF OF IT FALLING AS SNOW
NORTHWEST SECTIONS. THERE WILL BE AN ABRUPT LINE BETWEEN RAIN/SNOW.
WILL BE UPGRADING THE WATCH TO A WARNING FOR WEST/NORTHWEST SECTIONS
WITH A FEW COUNTIES ADDED ON THE EAST SIDE FOR A WINTER WEATHER
ADVISORY. THERE IS A GOOD POSSIBILITY THAT A FEW COUNTIES IN THE
WARNING MAY HAVE A SPREAD OF 5 TO 6 INCHES ACROSS THE COUNTY WITH
SOME IN WARNING CRITERIA AND SOME RECEIVING MUCH LESS. WINDS WILL
CONTINUE TO INCREASE OVERNIGHT AS THE LOW DEEPENS AND GRADIENT WINDS
INCREASE WITH HIGH PRESSURE REMAINS IN PLACE. WINDS OF 12 TO 25 MPH
WITH GUSTS TO 30 MPH SHOULD OCCUR ON THE BACK SIDE OF THE SYSTEM.
THIS WILL CAUSE BLOWING AND DRIFTING OF SNOW. SNOWFALL AMOUNT
OVERNIGHT LOOK TO APPROACH 5 TO 7 INCHES BY DAYBREAK NORTHWEST. THIS
MORNING DENISON HAD SNOW WHICH DID NOT MELT ALL THAT QUICKLY. UNLESS
THE GROUND PLAYS A ROLE IN MELTING FOR SEVERAL HOURS...AMOUNTS OF 5
TO 7 INCHES LOOK REASONABLE NORTHWEST TOWARD MORNING WITH LIGHTER
AMOUNTS TOWARD THE ADVISORY AREA.

.LONG TERM /SATURDAY THROUGH FRIDAY/...
SFC LOW WILL BE CROSSING EASTERN IA DURING THE MORNING AS IT
CONTINUES TO DEEPEN.  STRONG UVV'S WILL PERSIST DURING THE MORNING
ACROSS NORTHERN IA WHERE PCPN WILL BE ONGOING.  MAIN CONCERN IS
DELINEATION OF THE RAIN/SNOW LINE.  KFRM SOUNDINGS HAVE BEEN ALL
SNOW WITH KMCW STAYING PRIMARILY RAIN UNTIL THE HEAVIER PCPN ENDS
AND STRONG CAA TAKES OVER.  HAVE GENERALLY LINED IT UP FROM NEAR
FOREST CITY TO FORT DODGE THEN AUDUBON. ADDITIONAL ACCUMULATIONS ON
SATURDAY APPEAR TO BE FROM AROUND 1 INCH NEAR DENISON/CARROLL UP TO
3 TO 4 INCHES NEAR THE IA/MN AROUND KEST AND KAXA.  STRONG NORTH TO
NORTHWEST WINDS ARE ALSO EXPECTED WITH SOME BLOWING AND DRIFTING
SNOW...ALBEIT THE SNOW WILL BE RATHER MOIST AND HEAVY.  NEEDLESS TO
SAY...THE WARNING WILL CONTINUE INTO THE AFTERNOON WHEN MUCH OF THE
PCPN SHOULD COME TO AN END AND THE WIND SLOWLY SUBSIDES. MAY SEE
UPWARDS OF 10 INCHES IN SOME LOCATIONS NEAR THE MN BORDER.
OTHERWISE...A SECONDARY SHORTWAVE DROPS INTO THE TROF AND REINFORCES
THE UPPER LOW WHICH LINGERS ACRS MN UNTIL FINALLY EJECTING ON
SUNDAY.  WILL LIKELY SEE SOME CONTINUED SNOW SHOWERS ACRS THE FAR
NORTH THROUGH SUNDAY MORNING BEFORE THE SYSTEM PULLS TO THE EAST.
THEREAFTER...WILL SEE A SERIES OF FAST MOVING WAVES IN THE NORTHWEST
FLOW WITH BEST THREAT OF ANY PCPN COMING TUESDAY INTO WEDNESDAY...
ALBEIT LIGHT AND SCATTERED. TEMPERATURES WILL REMAIN AT OR BELOW
NORMAL FOR THE DURATION OF THE EXTENDED AS THE CANADIAN AIRMASS
LINGERS NEARBY.

.AVIATION...
12/18Z...WIDESPREAD RAIN WILL CONTINUE IN THE EAST AND SOUTHEAST
TODAY WITH SOME BREAKS IN THE ACTIVITY FROM TIME TO TIME. CIGS/VSBYS
