AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
333 PM CST FRI MAR 17 2006

.DISCUSSION...
MAIN FOCUS FOR TODAY CONTINUES TO BE PROLONGED SNOW EVENT EXPECTED
TO AFFECT MAINLY SOUTHWEST HALF OF THE CWA THIS WEEKEND. SOME MINOR
DIFFERENCES IN POSITION OF LARGE SCALE FEATURES BETWEEN THE GFS AND
NAM...BUT THESE DIFFERENCES ARE NOT AS SIGNIFICANT AS HAS BEEN SEEN
IN THE PAST FEW RUNS...AND A BLEND OF THE TWO MODELS SEEMS REASONABLE
FOR IRONING OUT SOME OF THE FINER DETAILS.

FOR TONIGHT...MAINLY JUST SOME INCREASE IN MID-HIGH CLOUDS...BUT
ISENTROPIC 285-275K SURFACES SHOWING SHARP LIFT AND RAPID SATURATION
WEST OF THE JAMES VALLEY BETWEEN 06Z-12Z TONIGHT...SO WILL KEEP LOW
POPS OUT THERE FOR LATE TONIGHT. LIFT AND SATURATION CONTINUE TO
INCREASE THROUGH THE DAY SATURDAY...AND WILL STEADILY INCREASE POPS
ACCORDINGLY. STRONGEST ISENTROPIC LIFT WILL AFFECT THE FAR SOUTHWEST
CWA LATER SATURDAY NIGHT INTO SUNDAY...AND WILL MENTION POTENTIAL
FOR HEAVY SNOW DURING THIS TIME. TOTALS OF 9 TO 15 INCHES A PRETTY
GOOD BET IN THE WARNING AREA...ESPECIALLY WITH HIGHER ELEVATIONS IN
GREGORY COUNTY. SEEMS AS THOUGH GFS IS GETTING A BETTER HANDLE ON
DRY PUSH COMING AROUND THE BASE OF THE SURFACE HIGH CENTERED OVER
NORTHERN MANITOBA...PROVIDING MORE CONFIDENCE THAT WE WILL SEE A
PRETTY TIGHT SNOW GRADIENT SOMEWHERE IN THE SOUTHWEST HALF OF OUR
CWA. WITH THE GFS AND NAM COMING INTO BETTER AGREEMENT ON MOISTURE
AND TIMING...POTENTIAL FOR SIGNIFICANT ACCUMULATIONS SEEMS CERTAIN
ENOUGH IN OUR SOUTH CENTRAL COUNTIES TO WARRANT ISSUING THE WARNING
FOR THEM AT THIS TIME. HOWEVER...STILL SOME UNCERTAINTY REGARDING
EXACTLY WHERE THAT TIGHT SNOW GRADIENT WILL END UP...SO HAVE OPTED
TO EXPAND THE WATCH A LITTLE FARTHER EAST.

SNOW SHOULD WIND DOWN FROM NORTH TO SOUTH MONDAY INTO MONDAY NIGHT...
AS LOW SLIDES EAST INTO THE MID-MISSISSIPPI VALLEY AND CANADIAN HIGH
PUSHES FARTHER SOUTH INTO THE NORTHERN PLAINS AGAIN.

EXTENDED RANGE FROM TUE THRU SAT SHUD PROVE TO BE A FAIRLY QUIET
PERIOD...BASED ON SUPERENSEMBLE OF DEVELOPING SPLIT AND BLOCKY FLOW.
WL ALSO BE MUCH MORE WINTERLIKE...DESPITE THE SUN/EARTH RELATIONSHIP
DEFINING THE START OF SPRING NEXT WEEK. LINGERING EFFECTS OF WEEKEND
SYSTEM COULD BRUSH THRU SRN PORTIONS OF NW IA EARLY TUE AS MAIN UPR
WAVE SHIFTS ACRS CNTRL/SRN PLAINS...AND KEPT LOWEST CHC GOING WITH
TENDENCY FOR THESE TYPES OF SYSTEMS TO WANDER A BIT MORE NORTHWARD
THAN PROGGED. OTHERWISE...HIGH PRESSURE WL SETTLE IN BEHIND FOR WED
USHERING IN RENEWED COOL PUSH.  MOST GUIDANCE SHOWS SOME DEGREE OF
TROUGHING IN SRN STREAM SLIDING BY TO S. 00Z ENSEMBLES SUGGEST
ENTIRE WED NIGHT/THU SYSTEM MAY BE A BIT SLOWER...BUT AGAIN SEEM TO
PUT MORE CREDIT IN IMPACT OF NRN STREAM TO DEFLECT WAVE MORE TO S.
RETURN WAA LIFT SUGGESTS AT LEAST A LOWER THREAT FOR SNOW DESPITE
BEST DYNAMIC LIFT REMAINING JUST S OF CWA...SO WL LIMIT TO SRN AREAS
FOR NOW.  DEEPENING TROUGH OFF W COAST SHUD START TO RECONSOLIDATE
FLOW AND PUSH SOME BETTER RIDGING TOWARD NRN PLAINS FRIDAY.

SNOWCOVER...AND POTENTIAL OF SIGNIFICANT ADDITION TO SOUTHWESTERN
CWA...PROVIDES A HIGH LEVEL CHALLENGE TO TEMPERATURE FORECASTS IN
EXTENDED.  WL ASSUME THAT STRONG CLIMO INFLUENCE WL DAMPEN WHAT SHUD
BE VERY COLD REGIME THROUGH MUCH OF EXTENDED.  LAST FEW DAYS HAVE
BEEN A STRUGGLE TO TMPS WITH ANY SUNSHINE OVR MOST SIG SNOWCOVER OVR
PARTS OF SW MN AND NW IA...AND PROBABLY A SIGN THAT TUE WILL NOT BE
AS WARM AS GUIDANCE...ESPLY 12Z MEX NUMBERS...DESPITE EXPECTED NET
LOSS OF SNOW THRU THIS TIME IN THE E.  WK FLOW WED AGAIN SUGGESTS TO
HIT FAIRLY COLD...BUT WL HAVE MODERATION OF AIRMASS WITH NICE LATE
MARCH SUN ANGLE.  BEHIND SYSTEM THU...ANOTHER WEAKER COOL PUSH
FOLLOWED BY WEAK FLOW INTO EARLY FRI...THEN STABILIZING WAA FRI.
AREAS BETWEEN LINGERING DEEPER SNOW ALG ERN I90 STRETCH...AND NEW
STUFF TO W...SHUD MODERATE QUITE WELL BY FRI.  TOOK A PAGE FROM THE
CONDITIONAL SNOWCOVER CLIMATOLOGY WHICH SUGGESTS AVERAGE MAX/MIN IN
THE LOWER TO MID 30S/MID TO UPPER TEENS...WHICH SEEMS A DECENT FIT
IF NOT ON THE WARM SIDE WITH FAIRLY WEAK FLOW AND 850HPA TMPS NOT
EXACTLY TOASTY FOR THIS TIME OF YEAR.
