NATIONAL WEATHER SERVICE SIOUX FALLS SD
930 PM CDT FRI MAR 28 2008

.DISCUSSION...
LATEST NAM OUTPUT AND GRDLY DVLPMNT OF PCPN ALF ALG FAR WRN SD/NE
BDR POINTS TO GRADUAL DVLPMNT OF SCT LGT PCPN TNGT AND SLW MOVG INTO
SWRN CRNR OF OUR FCST AREA VERY LATE. IN OTHER WORDS CURNT IDEA OF
GOING WITH JUST A SLGT CHC LGT RN/SHWRS OVER SWRN CRNR AND NOT TILL
09Z LOOKS OK. CURNT COOLNG TRENDS LOOK GOOD WITH TEMPS EXPCTD TO LVL
OFF LATR ARND OR JUST BLO FRZG THEN RISE A CPL DEGS AS PCPN MOVES IN
OVER ABV AREA. ALSO...IF PCPN ACTUALLY DOES DVLP LATE OVER THIS AREA
TEMPS LIKELY TO WARM A BIT MORE THAN WE HAVE UNDER THICKER CLD CVR
SO THAT SLGT CHC MENTN WILL STAY LIQUID. LGT RAIN/SHWR THREAT SHUD
CONT TO PUSH EWD INTO FCST AREA SAT MRNG AS WE HAVE IT SO NO
TEMPTATION TO CHANGE THAT EITHER. FRTHR E TEMPS WILL DROP SVRL DEGS
BLO FREEZG BUT WARM SAT IN PLANTY OF TIME FOR ANY LGT PCPN ARRIVAL.

&&
.AVIATION...
VFR WILL CONT THRU 12Z AND PSBLY WELL PAST THAT TIME WITH MID CLDS
MOVG OUT OF NERN FCST AREA AND SET TO INCRS FROM THE SW AFT 06Z. A
FEW SHWRS LGT SHWRS PSBL BY 12Z SW AND FRTHR E AFT 12Z. IF PCPN
DVLPS MORE THAN CURNTLY EXPCTED THERE STILL SEEMS A SLGT CHC FOR
SOME MVFR CIGS IN LGT RAIN DURG SAT BUT LWR LLVLS STILL LOOK PRETTY
DRY WITH PCPN REACHG SFC LIKELY TO BE PRETTY SCT AT MOST...WITH CIGS
AND VSBYS LIKELY NOT LWRNG BLO VFR.

.PREV DISCUSSION...
AREAS OF SOME LIGHT RAIN/SNOW IN JAMES VALLEY TRYING TO MAKE NORTH
TO NORTHEAST PROGRESS...BUT FINDING MORE DIFFICULTY MOVING INTO
RELATIVELY DRIER AIRMASS ACROSS NORTHEAST HALF OF THE FA. WILL TRACK
HIGHER CLOUD COVER FOR PREDOMINANTLY MID CLOUD DECK THROUGH THE AREA
THIS EVENING...WITH BREAK IN CLOUDS EXPECTED WEST TO EAST DURING THE
LATE EVENING/EARLY MORNING BEFORE CLOUDS INCREASE AGAIN AHEAD OF
NEXT WAVE LATE TONIGHT. STRONGER SOUTHEAST-SOUTH WINDS EXPECTED
TONIGHT...SO WE SHOULD NOT SEE TEMPS DROP TO THE EXTENT THAT THEY
DID OVER THE FRESH SNOW LAST NIGHT/THIS MORNING. BUT WILL KEEP THOSE
AREAS A LITTLE BELOW MODEL GUIDANCE...MAINLY ACROSS NORTHWEST IOWA.

JUST CAN/T SEEM TO SHAKE THE ACTIVE PERIOD WITH THE ENTIRE FORECAST
PACKAGE LOADED WITH PRECIPITATION CHANCES. SMALL WAVE WITH DECENT
THERMAL GRADIENT MOVES THROUGH WESTERN CWA IN THE MORNING HOURS.
TEMPERATURES IN NORTHERN PORTIONS OF CWA SUPPORT A MIXTURE OF RAIN
AND SNOW...WHILE AREAS FURTHER TO THE SOUTH REMAIN RAIN. LOOKING FOR
A BRIEF BREAK ON SATURDAY AFTERNOON FROM PRECIP...BEFORE A FEW
CONVECTIVE SHOWERS ROLL INTO FAR WESTERN CWA FROM THE HIGH PLAINS.
INSTABILITY REMAINS FAIRLY LIMITED AND ABOVE 700 MB SO ONLY
MENTIONED RAIN SHOWERS. OTHER CONCERN ON SATURDAY ARE GOING TO BE
THE WINDS AS LOW LEVEL JET GETS ENERGETIC AHEAD OF A DEVELOPING LOW
PRESSURE SYSTEM MOVING FROM SOUTHEASTERN MONTANA INTO SOUTHERN
MANITOBA SUNDAY EVENING. BUFKIT PROFILES SUGGEST LOW LEVEL JET WOULD
APPROACH 50 KNOTS AROUND 2000-2500 FEET...AND WITH MIXING POTENTIAL
NEAR THERE...WILL HAVE TO WATCH FOR POTENTIAL OF A WIND ADVISORY.
SOUTHEAST WINDS COMING OFF DWINDLING SNOW PACK ACROSS NORTHCENTRAL
IOWA...SO MAY TAKE TILL AFTERNOON HOURS TILL CRITERIA IS APPROACHED.

THE AFOREMENTIONED LOW CONTINUES TO LIFT OFF TO THE NORTHEAST
SATURDAY NIGHT AND THE ASSOCIATED COLD FRONT SWEEPS THROUGH THE
AREA. EXPECT SOME RAIN SHOWERS (OR POTENTIALLY SNOW SHOWERS ACROSS
SOUTHWEST MINNESOTA) WITH THE FRONT AS IT MARCHES EAST.  THE
MIDLEVEL FRONT IS EXPECTED TO STALL OVER SOUTHERN PORTIONS OF CWA
SATURDAY NIGHT...AND WILL BEGIN TO LIFT NORTH ACROSS THE CWA SUNDAY
NIGHT AS THE NEXT SHORT WAVE TRAIN APPROACHES FROM THE WEST.
FORECAST AREA IS LOCATED IN THE RIGHT REAR QUADRANT OF THE UPPER
LEVEL JET RESULTING IN AMPLE UPPER LEVEL SUPPORT. SECONDARY AREA OF
LOW PRESSURE SPINS UP ALONG THE THERMAL BOUNDARY ACROSS THE CENTRAL
PLAINS. STRONG 700 MB FRONTOGENESIS SLIDES NORTH INTO SOUTHERN
CWA...AND HAVE INCREASED POPS ACROSS THE ENTIRE CWA ON MONDAY WITH
THE FOCUS ON NORTHWEST IOWA. COULD BE LOOKING AT AN ACCUMULATING
SNOW EVENT ON MONDAY...ESPECIALLY ALONG AND NORTH OF I-90 WHERE HIGH
TEMPERATURES WILL STRUGGLE TO REACH 10-15 DEGREES BELOW NORMAL.

ON WEDNESDAY A WARM AIR ADVECTION BAND SETS UP CREATING AN
OVERRUNNING EVENT.  AMOUNTS LOOK TO BE RELATIVELY MINOR WITH
MOISTURE REMAINING SOMEWHAT LIMITED.

CHUNK OF ENERGY WORKS IN FROM BLOCKING PATTERN SET UP OVER THE WEST
COAST AND IS EXPECTED TO MOVE ACROSS THE CENTRAL PLAINS ON
THURSDAY.  BULK OF THE WAVE IS EXPECTED TO REMAIN SOUTH...THOUGH THE
NORTHERN FRINGES MAY ECLIPSE SOUTHERN PORTIONS OF THE FORECAST AREA.

FRIDAY LOOKS RELATIVELY QUIET AHEAD OF A BACKDOOR COLD FRONT THAT
MAY AFFECT THE NORTHERN PLAINS NEXT WEEKEND.  GFS IS SUGGESTING 925
MB TEMPS MAY FALL AS LOW AS -20 AROUND THE US CANADIAN BOARDER.
JUST CAN/T SEEM TO SHAKE THIS COLD ACTIVE PATTERN.
