AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
444 AM CST TUE DEC 15 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 444 AM CST TUE DEC 15 2015

COMPLEX NEXT 24 HOURS...TO SAY THE LEAST. SOMEWHAT PROBLEMATIC IN
DEALING WITH THE IMMEDIATE TERM AND THE AREAS OF FREEZING DRIZZLE.
ROAD REPORTS INDICATE THAT SLICK SPOTS ARE ACROSS PARTS OF EAST
CENTRAL SD. VISIBILITY REPORTS AND WEBCAMS ARE SHOWING THAT OVERALL
IS A FAIRLY SPOTTY VISIBILITY REDUCTION. SO FAR AT KFSD...LIGHT ICE
ACCUMULATIONS ONLY SPORADIC ON ELEVATED OBJECTS...AND NOT ALL
OBJECTS...AS ROAD SURFACES HAVE REMAINED ONLY WET. LIKELY SOME
VARIATION WITH LOCAL TEMPERATURE...SO IF GET MORE REPORTS OF SLICK
CONDITIONS...MAY HAVE TO THROW OUT A WINTER WEATHER ADVISORY THROUGH
THE MORNING FOR PARTS OF SW MN/ERN SD...AND PERHAPS INTO EXTREME NW
IA. GRADUALLY SHOULD SEE TEMPS START TO RECOVER A FEW DEGREES
THROUGH THE MORNING...AS LOW LEVEL FLOW TURNS MORE EASTERLY.

ATTENTION THEN TURNS THE ONCOMING WINTER STORM. CENTER OF UPPER
LEVEL LOW CHURNING ACROSS SOUTHERN COLORADO EARLY THIS MORNING...
AND EXPECTED TO EVOLVE TO A STACKED UPPER LOW ACROSS NORTHWESTERN
IOWA BY WEDNESDAY MORNING. MAIN DIFFERENCE FROM YESTERDAY IS A
SLOWER ONSET OF THE DEEPER SATURATION AND LIFT...AS WILL LIKELY TAKE
UNTIL AT LEAST 18Z TO START TO SEE INCREASE IN MOISTURE ALONG THE
MID LEVEL FRONTAL BOUNDARY ALONG THE WESTERN BORDER...WITH LIFT
DEVELOPING FURTHER EAST SUSTAINING THE DRIZZLE/FREEZING DRIZZLE
THREAT. SHOULD BE A FAIRLY RAPID EXPANSION IN THE PRECIPITATION
COVERAGE ACROSS THE WEST IN THE 18Z-21Z WINDOW WITH THE PV ADVECTION
RUNNING RIGHT UP THE BOUNDARY...IN PRESENCE OF SOME MARGINAL
STABILITY. SHOULD ALSO START TO SEE DEVELOPMENT OF WARM ADVECTION
WING OF PRECIPITATION ALONG THE MISSOURI RIVER BY MID AFTERNOON...
LIFTING STEADILY NORTHEAST THROUGH THE EVENING. THIS MAY RESULT IN
ACTIVITY PICKING UP AND DROPPING OFF FOR A TIME FOR AREAS EAST OF
THE JAMES RIVER. INITIAL SHOT WOULD LIKELY GIVE AN INCH OR TWO
SNOWFALL ACROSS THE EAST...WITH NORTHWARD PUSH OF UPPER LOW WRAPPING
WARM AIR ALOFT NORTHWARD THROUGH THE EASTERN CWA THROUGH EARLY
MORNING...WITH TRANSITION FROM MIX OR SNOW TO RAIN THROUGH THE
NIGHT SOUTH OF ROUGHLY A WINDOM TO VERMILLION LINE.

WHAT HAS CHANGED IS AN INCREASING CONCERN ABOUT A SECONDARY
MESOSCALE BAND OF HEAVIER SNOWFALL DEVELOPING LATER TONIGHT AND
WEDNESDAY MORNING NEAR THE HEART OF THE CWA. STRONG FRONTOGENETIC
FORCING IN A MORE SHALLOW LEVEL DEVELOPS ON THE BACK SIDE OF THE
TROWAL AIRSTREAM...EXTENDING ACROSS FAR EASTERN SOUTH DAKOTA...
INTENSIFYING BETWEEN 06Z-12Z. THERE IS POTENTIAL FOR A SECONDARY
BAND OF HEAVIER PRECIPITATION TO DEVELOP RIGHT ACROSS THE TRI STATE
AREA...BETWEEN THE WARMER AIR AND MIXED TO RAIN TYPES TO THE EAST...
AND THE SHARPLY COLDER TEMPS ALOFT WEST. EPV STRONGLY NEGATIVE ABOVE
THIS LOWER LEVEL FRONTAL ZONE WITH ONLY A SMALL DEGREE OF
SEPARATION. TEMPS ALOFT WOULD PUSH THIS OVER TO SNOW IN MOST OF THE
BAND. WHAT ADDS CONFIDENCE IS THAT ALL HIGHER RESOLUTION SOLUTIONS
HAVE PICKED UP ON THIS FEATURE WITH 00Z/06Z RUNS...AS WELL AS THE
00Z ECMWF ON ITS OWN SCALE AND WITH USUAL LOWER QPF BIAS.
COORDINATED AN INCREASE IN QPF/SNOW WITH EXPECTED BAND...BUT COULD
VERY WELL NEED A BIGGER INCREASE IF THIS FEATURE DOES EVOLVE.

WILL ALSO SEE WIND PICK UP BEHIND THE SURFACE LOW...STARTING AFTER
MIDNIGHT ACROSS THE FAR WEST BEHIND THE INVERTED TROUGH...AND
EXPANDING ACROSS MUCH OF SOUTHEAST SOUTH DAKOTA BY 12Z. SOME AREAS
OF BLOWING SNOW ARE LIKELY...ESPECIALLY FROM THE JAMES VALLEY
WESTWARD BY DAYBREAK WED.

AS A RESULT OF SNOWFALL AND BLOWING SNOW EXPECTATIONS...HAVE ISSUED
A WINTER STORM WARNING FOR THE WESTERN AND FAR NORTHERN CWA FROM
THIS AFTERNOON THROUGH MIDDAY WEDNESDAY. IN THESE LOCATIONS...
LOOKING FOR GENERALLY 5 TO 7 INCHES OF SNOWFALL...AS WELL AS SOME
MORE LIKELY BLOWING SNOW IMPACTS INTO WEDNESDAY. FURTHER TO THE EAST
TOWARD A MARSHALL TO SIOUX FALLS TO YANKTON LINE...WILL CARRY A
WINTER WEATHER ADVISORY FOR 3 TO 5 INCHES OF SNOWFALL. LIKELY WILL
SEE A SHARP EASTERN EDGE TO HEAVIER SNOWFALL WITH THE THE WARMER
TEMPS ALOFT AND EXPECTED SECONDARY BAND LATER TONIGHT AND WED.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 444 AM CST TUE DEC 15 2015

ON WEDNESDAY...THE UPPER LOW LIFTS RAPIDLY NORTHEASTWARD. THE
SURFACE LOW FOLLOWS SUIT AND LOOKS TO LIFT NORTHEASTWARD USING A
CONSENSUS TRACK OF JUST EAST OF SIOUX FALLS 12Z WED...TO CENTRAL MN
BY 18Z. THE MOST DISTURBING ITEM IN THE FORECAST FOR WEDNESDAY IS
THE STRONG POTENTIAL FOR A BRIEF MODERATE TO HEAVY SNOW BAND JUST
BEHIND THE SURFACE LOW...POSSIBLY ALONG AN AXIS FROM YANKTON AND
VERMILLION...TO AROUND THE SIOUX FALLS AREA...AND NORTHWARD TO
BROOKINGS SD AND IVANHOE MN. EVEN THE ECMWF WITH ITS GLOBAL MODEL
STRUCTURE IS TRYING TO PICK UP ON THIS FEATURE ALBEIT LATE TONIGHT.
THE GFS IS ALSO TRYING TO SHOW IT...ALTHOUGH A BIT FURTHER EAST. BUT
THE HIGH RESOLUTION MODELS INCLUDING THE NAMDNG...ARW...NMM AND
NAM12 ARE SHOWING THIS POTENTIAL IN THE TRACK DESCRIBED ABOVE. THIS
CLOSE TO THE EVENT...DECIDED TO FOLLOW THE HIRES SOLUTIONS MORE SO
THEN THE GFS...AS THEY DID A GOOD JOB IN SHOWING THE MESOSCALE
FEATURES WITH THE MID NOVEMBER SNOWFALL WHICH WAS AN UNSTABLE EVENT.
WHAT THE HIRES MODELS ARE KEYING ON IN THE SMALL SCALE IS STRONG LOW
LEVEL DYNAMICS. VERY STRONG FRONTOGENESIS EXISTS IN THIS
AFOREMENTIONED AREA WEDNESDAY MORNING IN THE 900-800MB LAYER...WITH
VERY UNSTABLE EPV* NOTED ABOVE IT IN THE 750-700MB LAYER. THAT LAYER
IS SATURATED ALSO WITH THE MID LEVEL DRY AIR LONG GONE BY THEN.
FINALLY...THERE IS A THIN LAYER OF DENDRICITY AT THE TOP OF THE
CLOUD LAYER IN THE 700-600MB LAYER. IN THE MESOSCALE...THE THERMAL
PATTERN OFF THE SURFACE NEAR 850MB AS WELL AS THE THETAE FIELDS SHOW
STRONG THETAE AND THERMAL RIDGING CURLING WESTWARD INTO SOUTHWEST MN
AT 12Z TO 15Z JUST EAST AND NORTH OF THE LOW LEVEL LOW PRESSURE
SYSTEM. THIS CREATES QUITE A COMMAHEAD...WITH THE WESTERN EDGE OF
THE COMMA IN THE ENHANCED ZONE OF ASCENT AND INSTABILITY CLOSE TO I
29 EARLY WEDNESDAY DESCRIBED ABOVE. EVEN THE 850-800MB ELEVATED
LIFTED INDEX VALUES ARE +2C ALONG I 29 WEDNESDAY MORNING. THUS THIS
IS PART OF THE REASON WE PUT A WINTER WEATHER ADVISORY OUT FOR THE
YANKTON...TO SIOUX FALLS TO MARSHALL STRETCH...AND WILL BE MONITORED
FOR ANY HIGHER AMOUNTS WHICH COULD OCCUR AND CREATE A WARNING TYPE
SITUATION IF BRIEF HEAVY SNOW OCCURS EARLY WEDNESDAY. FURTHER
WEST...A MID LEVEL DRY SLOT WILL LIKELY AFFECT MANY OF OUR WESTERN
ZONES INCLUDING HURON AND MITCHELL IN THE MORNING GIVING THEM ONLY
VERY LIGHT SNOW AND VERY MINIMAL ADDITIONAL ACCUMULATIONS. BY
AFTERNOON...THE SNOW LIFTS OFF RAPIDLY TO THE NORTH AND NORTHEAST.
THE TRACK OF THE LOW STILL IS VERY UNFAVORABLE FOR SNOWY CONDITIONS
ON WEDNESDAY GENERALLY ALONG AND EAST OF HIGHWAY 60. THOSE LOCATIONS
WILL SEE VERY MINIMAL IF ANY ACCUMULATIONS. IN FACT...WOULD NOT RULE
OUT EVEN A BIT OF VERY LIGHT RAIN WEDNESDAY MORNING IN THOSE AREAS
WITH THE LOW LEVEL WARM AIR WRAPPING BACK IN FROM THE EAST.

WIND IS THE OTHER CONCERN ON WEDNESDAY. AS THE LOW EXITS...THEY WILL
INCREASE TO A 25 TO 40 MPH RANGE ACROSS OUR EASTERN ZONES THROUGH
THE DAY WHICH COULD CREATE BLOWING SNOW AND REDUCED VISIBILITIES IN
THE HEADLINED AREAS. THE MIXED LAYER SHOWS AROUND 35 KNOTS SO PUT
THOSE IN FOR OUR GUSTS ON WEDNESDAY. TEMPERATURES WILL LIKELY SLOWLY
GO DOWN THROUGH THE DAY SO EXPECT HIGHS IN THE MORNING.

THURSDAY WILL ALSO BE QUITE WINDY. ALL MODELS SHOW A SHORT WAVE
MOVING ACROSS OUR FORECAST AREA DURING THE DAY ALONG THE TROUGH OF
THE LONG WAVE. THIS WILL REINFORCE SOME CHILLY AIR AND OF COURSE THE
WINDS. FURTHERMORE...THERE IS A CHANCE FOR SOME FLURRIES WHERE THE
MOISTURE DEPTH EXTENDS THROUGH 700MB GENERALLY ALONG AND NORTH OF A
HURON...TO SIOUX FALLS...TO SPENCER IOWA LINE. DID NOT PUT THAT IN
THE FORECAST YET HOWEVER DUE TO CONCERNS IN THE NEAR TERM FIRST. BUT
IS SOMETHING FOR FUTURE SHIFTS TO THINK ABOUT.

WARMER WEATHER WILL RETURN FOR THE WEEKEND AND EARLY NEXT WEEK AS
UPPER RIDGING TAKES HOLD FOR A LITTLE WHILE IN THE WEST.
