AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
353 PM CST SAT JAN 29 2011

.SHORT TERM /TONIGHT/...
WEAK WAVE AND UPPER LEVEL BOUNDARY CONTINUE TO PRODUCE LIGHT SNOW
ACROSS NORTHERN IA THIS AFTERNOON. QPF AMTS ADJUSTED TO REFLECT UP
TO AN INCH OF ACCUM PRIOR TO EVENING FCST. HAVE KEPT SOME RESIDUAL
SNOWFALL GOING EAST INTO THE EVENING HOURS WITH LITTLE IF ANY
ACCUMULATION EXPECTED. STORY FOR THE REMAINDER OF NIGHT WILL BE COLD
AIR ADVECTION WITH NORTHERLY WINDS. CLOUDS REMAIN A CHALLENGE WITH
LARGE AREA OF ST ACROSS THE DAKOTAS WORKING SOUTHEAST. SOME UPSTREAM
BREAKS...BUT CONFIDENCE REMAINS LOW THAT TOTAL CLEARING WILL OCCUR
OVERNIGHT AS COLD AIR SETTLES INTO THE AREA. IN EITHER EVENT...HAVE
KEPT MINS MUCH COOLER NORTH WITH LOWS NEARING ZERO. SNOW WILL END
NORTHEAST THIS EVENING.

.LONG TERM /SUNDAY THROUGH SATURDAY/...SEVERAL CONCERNS WITH THE
EXTENDED PERIOD WITH CENTRAL IOWA IN BETWEEN TWO SYSTEMS EARLY TO
MID NEXT WEEK. MODELS ARE IN FAIR THROUGH MID WEEK WITH TIMING
AND PLACEMENT OF SNOW...WITH THE ECMWF A BIT MORE BULLISH WITH THE
QPF. STILL SOME DISCREPANCIES WITH THE SECOND MAIN TROUGH ON
TUESDAY.  LEANED TOWARDS A BLEND OF THE SREF/ECMWF FOR POPS AND
NAM/GFS/SREF FOR QPF AMOUNTS.

SUNDAY THROUGH TUESDAY...MID LEVEL SHORTWAVE CUTS ACROSS MINNESOTA
AND NORTHERN IOWA SUNDAY NIGHT INTO MONDAY.  THIS WILL BE IN
CONJUNCTION WITH SOME GOOD ISENTROPIC LIFT DEVELOPING DURING THE
SAME TIME FRAME.  QPF AMOUNTS SEEMED A LITTLE HIGH WRT TO THE
GFS/ECMWF BUT STILL GET ROUGHLY 7-8 INCHES WITHIN A 24-30 HOUR
PERIOD BEGINNING AROUND 06Z MONDAY AND LASTING THROUGH 12Z TUESDAY.
BUFKIT HAS SLIGHTLY MORE SNOW THAN THE COBB OUTPUT...BUT STILL COULD
SEE SOME WARNING CRITERIA SNOWFALL IN SOME ISOLATED AREAS ALONG
THE NORTHERN TWO TIERS OF COUNTIES BY LATE MONDAY NIGHT. BEST
DENDRITIC SNOWFALL WILL BE FROM 06Z TO 18Z MONDAY WHICH MATCHES UP
WELL WITH A BROAD AREA OF FN VECTOR DIVERGENCE BETWEEN 700-750MB
BY 12Z MONDAY. BUFR SOUNDINGS BECOME SATURATED BY 06Z MONDAY AND
FINALLY LOSE THEIR ICE INTRODUCTION SOMETIME TUESDAY AFTERNOON.
RIGHT NOW...ISSUED A WINTER STORM WATCH FROM 06Z MONDAY THROUGH
18Z TUESDAY FOR SNOW AND THEN BLOWING SNOW BY TUESDAY. STRONG CAA
DEVELOPS BEHIND THE SECOND MAIN TROUGH THAT MOVES THROUGH ON
TUESDAY. WINDS ATOP THE MIXED LAYER RANGE FROM 25-30KTS TUESDAY
AFTERNOON AND INCREASE WEDNESDAY NIGHT. WENT LOWER ON TEMPS FOR
TUESDAY AS SECOND TROUGH IS SLIGHTLY FURTHER SOUTH THAN PREVIOUS
MODEL RUNS.

SNOWFALL WRT TO SECOND...STRONG UPPER LEVEL TROUGH OF LOW PRESSURE
WILL PUSH ACROSS THE REGION TUESDAY INTO EARLY WEDNESDAY WITH THE
STRONGEST ENERGY OF THIS SYSTEM FURTHER SOUTH IN MISSOURI. SOUTHEAST
IOWA LOOKS TO GET A DECENT AMOUNT SNOW WITH IT BEING IN THE LOCATION
OF THE BAROCLINIC ZONE SETTING UP ON THE NORTHWEST SIDE OF THE SURFACE
LOW.  TROWAL DEVELOPS BY TUESDAY AFTERNOON...BUT LOOKS TO REMAIN
JUST TO THE SOUTHEAST OF THE FORECAST AREA.
REGARDLESS....IMPRESSIVE ISENTROPIC LIFT AND BY 00Z WEDNESDAY
THROUGH 12Z WEDNESDAY ACROSS THE SOUTHEAST.  QPF AMOUNTS ARE
EXTREMELY HIGH...ESPECIALLY THE ECMWF.  SNOW RATIOS ARE ROUGHLY 15:1
ATTM WHICH RESULTED IN SNOW AMOUNTS NEAR 10 INCHES BY EARLY WEDNESDAY
MORNING NEAR THE OTM AREA. HOWEVER...ATTM HELD OFF ON ANY
HEADLINES AS STILL SOME UNCERTAINTY WITH PLACEMENT OF HEAVIEST
SNOWFALL ACROSS THE SOUTHEAST.

WEDNESDAY THROUGH FRIDAY...MUCH COLDER TEMPERATURES FILTER INTO
THE STATE BY WEDNESDAY INTO THURSDAY WITH STRONG ARCTIC SURFACE
HIGH BUILDING INTO THE REGION. LOWERED TEMPS ACROSS THE FORECAST
AREA ABOUT 3-5 DEGREES FOR HIGHS WEDNESDAY AND LOWS THURSDAY
MORNING.

&&

.AVIATION...29/18Z
COMPLICATED FCST THIS PERIOD DUE TO MULTIPLE CLOUD DECKS AND WEAK
IMPULSE MOVING EAST/SOUTHEAST TODAY. LEADING EDGE OF COLD AIR
PRODUCING AN AREA OF MVFR CIGS NEAR US HIGHWAY 30 AND THIS AREA IS
DRIFTING EAST SOUTHEAST WITH TIME...THOUGH AHEAD OF IT EARLIER MVFR
CIGS HAVE GIVEN WAY TO VFR CIGS ATTM. IMMEDIATELY BEHIND THE COLD
AIR ADVECTION...CIGS GO BKN VFR ONCE AGAIN WITH MVFR POCKETS NORTH
INTO MN. WEST OF THE REGION AN AREA OF MVFR/IFR CIGS ASSOCIATED WITH
LAST NIGHTS RADIATIONAL COOLING IS MOVING ESE AND HAS EXPANDED AS
FAR EAST AS KOFK AND KSUX. EXTRAPOLATION TAKES IT INTO WESTERN IOWA
AS THE EVENING PROGRESSES. MODELS NOT HANDLING FEATURES VERY WELL
THOUGH RUC SEEMS TO HAVE A HANDLE ON CURRENT RH FIELDS THROUGH 03Z.
GIVEN CURRENT TRENDS HAVE PULLED BACK ON LESS OPTIMISTIC CIGS ACROSS
CENTRAL SECTIONS THOUGH THERE SHOULD STILL BE A BRIEF WINDOW BETWEEN
18 AND 20Z THAT MVFR CIGS RETURN AT KDSM BEFORE GENERAL LOWERING
TAKES PLACE AFT 00Z SOUTH SITES KOTM AND KDSM. CONCERNS OF LOWERING
CIGS TURN NORTH AFT 03Z AS IFR CIGS DEVELOP AND MOVE SOUTH FROM MN.
