AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
413 AM CST WED FEB 28 2007

.SYNOPSIS...
160+KT JET NOW PUSHING ACROSS BAJA/SWRN CONUS WITH SHRT WVS NOTED
OVER CA/NV.  OTHER WEAKER WVS NOW EXTEND FM ERN MT THROUGH MO RIVER
VALLEY WITH STRONG KINEMATIC AND THERMODYNAMIC FORCING APPROACHING.
PCPN MAINLY VIRGA FOR NOW WITH RADAR ECHOS WORSE LOOKING THAN SFC
OBS SUGGEST.  09Z SFC ANLYS SHOWS LOW PRES IN FAR SWRN CO WITH
WRMFNT ALG KS/OK BORDER.  SFC DEWPOINTS WELL INTO THE 40S AND EVEN
LOW 50S IN OK WITH 100-300 J/KG MUCAPES N OF BNDRY INTO SERN KS/SWRN
MO.

.DISCUSSION...
MANY ASPECTS OF THIS STORM TO WORRY ABOUT RANGING FROM POTENTIAL
BLIZZARD N AND W TO SVR TSTMS FAR SE.  AFOREMENTIONED STRONG FORCING
REMAINS STEADY TODAY SO EXPECT SATURATION AND PCPN TO COMMENCE LATER
THIS MORNING WITH POPS INCREASING TO LIKELIES AND CATEGORICAL IN
MOST LOCATIONS BY AFTERNOON.  FORECAST SOUNDINGS SUGGEST SNOW NORTH
WITH RAIN...FREEZING RAIN OR SLEET ALL POSSIBLE THIS MORNING CENTRAL
AND SOUTH...TRANSITIONING TO FREEZING RAIN OR SNOW NORTH AND RAIN
SOUTH.  STAYED AT OR BELOW COOL END OF GUIDANCE WITH ELY
WINDS...CLOUDS AND PCPN DEVELOPING.  THIS FORCING EXITS FORECAST AREA
THIS EVE DURING WHAT LOOKS TO BE RELATIVE MIN IN UVM.  SOUNDINGS
SHOW SATURATION IN LOWEST 5-10KT FEET SO WE ARE LOOKING AT MINIMAL
QPF DURING THIS PERIOD.  PCPN TYPE WED EVE LOOKS TO BE PRIMARILY
LIQUID.  MID LEVEL RH DIMINISHES AND NOT MUCH ICE INTRODUCTION NRN
PORTIONS WHERE FRZG RAIN/DRZL MORE LIKELY...BUT DID MENTION TOKEN
SNOW REFERENCE WITH POTENTIAL FOR SPOTTY SATURATION <-10C.  HAVE
SWITCHED WINTER STORM WATCH TO WINTER WX ADVY DURING THIS PERIOD.

SITUATION THEN BECOMES MUCH MORE INTERESTING AND ACTIVE LATE WED
NIGHT.  GFS APPEARS TO BE THE MOST SE SOLUTION OF H7/H5 LOWS...WITH
NAM/GEM/ECMWF A TAD MORE NWLY.  MUCH LIKE HPC...WILL FAVOR THIS
CONSENSUS AS STORMS SUCH AS THESE RARELY VERIFY WITH SERN FRINGE OF
SOLUTIONS.  DO NOT OFTEN BUST HEAVY SNOW AXIS FARTHER S THAN
EXPECTED.  NAM DETAILS HAVE SHRT WV DEEPENING RAPIDLY OVERNIGHT WITH
CORRESPONDING DROP IN SFC PRESSURES.  NOT QUITE BOMB CRITERIA...BUT
WILL NOT MAKE MUCH DIFFERENCE WITH LOW DOWN TO 977MB BY THU NIGHT.
VERY STRONG WARM ADVECTION/ISENT LIFT ALONG 305K SFC...WHICH IS
ALONG DENDRITIC ZONE AS WELL...SUGGESTS SURGE OF CONVECTION INTO
SERN QUARTER OF IA AFT MIDNIGHT.  CONSIDERING THE AMOUNT OF
FORCING...SPC OUTLOOK MAY NOT BE AGGRESSIVE ENOUGH N AND WOULD NOT
BE SURPRISED TO SEE SVR HAILERS AROUND KOTM INTO EARLY THU.

FARTHER N AND W...HIGH END FORCING IN PLACE IN THE MESO AND SYNOPTIC
SCALES.  DEEP INTENSE QG FORCING DEPICTED WITH VERY LOW STATIC
STABILITIES DRAWN NORTHWARD ON NOSE OF DRY SLOT.  THIS IS IN
ADDITION TO THE IMPRESSIVE FRONTOGENETICAL FORCING SO EXPECT INTENSE
BANDING WITH 1/HR + RATES IN BROADER PCPN SHIELD.  305K ISENT SFC
SHOWS NICE TROWAL WITH MOISTURE TRANSPORT WRAPPED INTO SYS FROM THE
SE...SEEMING A DIRECT TAP OF THE WARM CONVEYOR BELT WHICH YOU DO NOT
SEE TOO OFTEN.  WOULD NOT BE SURPRISED TO SEE THUNDER SNOW.  CURRENT
THINKING IS FOR 6-14 INCHES ALONG AND NW OF GREENFIELD-WEBSTER
CITY-HAMPTON LINE WITH AMOUNTS OF A FOOT OR MORE POSSIBLE IN NRN
IA.  SEVERAL CONCERNS REGARDING THESE AMOUNTS HOWEVER ON BOTH ENDS
OF THE SPECTRUM.  06Z NAM CONTINUES ITS NW TREND EVER SO SLIGHTLY
WHICH COULD DIMINISH AMOUNTS...BUT ALSO MAY HAVE PROBLEMS ON THE
HIGH END CONSIDERING THE UVM AND CONVECTION.  HOPEFULLY THE
TRANSIENT NATURE OF SYS WILL KEEP THINGS SOMEWHAT UNDER CONTROL
AMOUNT WISE.  WHAT IS OF HIGHER CONFIDENCE IS THE WIND POTENTIAL.
WHATEVER SNOW DOES FALL WILL BE VERY WIND BLOWN WITH GUSTS UP TO 45
MPH.  CONSIDERING WHAT WE HAVE EXPERIENCED THIS WEEKEND AND
POTENTIAL WITH THIS STORM...WILL HEIGHTEN AWARENESS AND SWITCH LATER
WINTER STORM WATCH TO BLIZZARD WATCH.  SYS SHOULD CONTINUE ITS
EFFECTS WITH LIGHT SNOW BUT STILL STRONG WINDS AND BLOWING EVEN INTO
FRIDAY AS SECONDARY SHRT WV ROTATES AROUND PARENT LOW.

TEMP WISE...EXPECT RATHER FLAT TREND TONIGHT THEN EARLY HIGHS AND
FALLING READINGS THU...ESPECIALLY CENTRAL AND WEST.  MAXES SHOULD BE
TOWARD LOW END OF GUIDANCE.  WITH PERSISTENT WINDS AND CLOUD
COVER...HAVE STAYED TOWARD WARMER END THU NIGHT.  INTO FRI...MIXING
MAY DEVELOP SNOW SHOWERS WITH MAXES MAYBE TOWARD HIGH END.  NO LATER
CHANGES AS PRIMARY FORECAST EFFORT INTO THIS POTENTIALLY VERY HIGH
END STORM.  WSWS WILL BE VERY STRONGLY WORDED.
