AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1131 AM CST THU JAN 2 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 422 AM CST THU JAN 2 2014

THERE IS SOME LIGHT SNOW FROM WESTERN SD INTO SOUTH CENTRAL SD AT
THIS TIME ASSOCIATED WITH A WEAK UPPER LEVEL WAVE MOVING INTO
NORTHERN SD. THIS WAVE IS EXPECTED TO EXIT LATER THIS MORNING.
PRIMARILY EXPECT FLURRIES BUT THERE COULD BE UP TO A QUARTER INCH OF
SNOW ALONG AND WEST OF THE MISSOURI RIVER.

OTHERWISE...THE MAIN FOCUS IS TEMPERATURES...BOTH MAX AND MINS AS
WELL AS TRENDS OVER THE NEXT 24 H. CURRENTLY THERE ARE MID AND HIGH
CLOUDS OVER MUCH OF THE AREA. DIFFICULT TO TELL HOW THICK CLOUDS ARE
FROM IR IMAGERY BUT BASED UPON TEMPERATURE TRENDS IT APPEARS ALONG
AND EAST OF I-29 CLOUDS ARE THIN AND THEREFORE THESE AREAS HAVE SEEN
TEMPERATURES FALL INTO THE TEENS BELOW ZERO. WITH MIXING LIMITED...
TEMPERATURES ARE UNLIKELY TO REACH ZERO NORTH OF I90 AND EAST OF THE
JAMES RIVER. WHERE CLOUDS ARE THICKEST IN SOUTH CENTRAL SD...TEMPS
ARE ALREADY ABOVE ZERO AND PARTS OF GREGORY COUNTY MAY REACH 10
ABOVE LATE THIS AFTERNOON.

HIGH PRESSURE SLOWLY MOVES EAST OF THE AREA OVERNIGHT. THIS WILL
RESULT IN AN INCREASE IN SOUTH WINDS THROUGH THE NIGHT. ACCOMPANYING
THIS INCREASE IN WINDS WILL BE INCREASING MID CLOUDS AHEAD OF A WARM
FRONT. IT IS INITIALLY VERY DRY BELOW 10 KFT...SO DO NOT THINK THERE
WILL BE ANY PCPN WITH THIS FRONT UNTIL FRIDAY MORNING. WITH MOSTLY
CLOUDY SKIES AND SOUTH WINDS AROUND 10 MPH IN CENTRAL SD BY SUNSET DO
NOT SEE TEMPERATURES FALLING AT ALL. EAST OF THE JAMES RIVER...WINDS
WILL BEGIN THE NIGHT LIGHT AND VARIABLE AND SKIES WILL BE MOSTLY
CLEAR SO EXPECT A RAPID FALL OF 5 TO 10 DEGREES IN THE EARLY EVENING
WITH MOST PLACES REACHING THEIR LOWS FROM 0 TO 10 BELOW BETWEEN 6 AND
10 PM. THE COLDEST TEMPERATURES WILL BE IN SW MN. THEN AS WINDS
GRADUALLY PICK UP AND CLOUDS INCREASE FROM WEST TO EAST...
TEMPERATURES WILL BECOME STEADY AND THEN SLOWLY RISE THROUGH THE
NIGHT. BY SUNRISE MOST PLACES WILL BE AT OR ABOVE ZERO. WINDS MAY
PRODUCE PATCHY BLOWING SNOW...ESPECIALLY IN MORE EXPOSED AREAS
OUTSIDE OF RIVER VALLEYS. WITH A STRONG INVERSION SET UP OVER SW MN
AND SW FLOW OF 30 TO 40 KTS PERPENDICULAR TO THE BUFFALO RIDGE...THIS
IS IDEAL SET UP FOR STRONG SOUTHWEST WINDS TO DEVELOP LATE TONIGHT.
SO EXPECT WINDS GUSTING OVER 30 KTS BY SUNRISE. THEREFORE...BLOWING
SNOW AROUND MARSHALL...TRACY AND SLAYTON MAY BE MORE SIGNIFICANT...
PERHAPS REDUCING VISIBILITIES TO HALF MILE LATE TONIGHT. HAVE NOT
ISSUED ANY TYPE OF ADVISORY AT THIS POINT BUT WILL LET LATER SHIFTS
REEXAMINE POSSIBILITY.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 422 AM CST THU JAN 2 2014

TEMPERATURES WILL REMAIN THE FOCUS AND MAIN CHALLENGE THROUGH THE
LONGER RANGE. RISE IN TEMPERATURES TO NEAR OR EVEN ABOVE NORMAL
SHOULD CONTINUE THROUGH THE DAY FRIDAY...WITH HIGHS IN MOST AREAS
REALIZED TOWARD EVENING BEFORE COLD ADVECTION MOVES IN FROM THE
NORTH. STRONG SOUTH WINDS EXPECTED THROUGHOUT THE DAY FRIDAY AHEAD
OF THIS BOUNDARY...AND WITH RECENT LIGHT SNOW COVER HAVING LITTLE
OPPORTUNITY TO SETTLE/CURE BEFORE THE WINDS PICK UP...WILL CONTINUE
MENTION OF BLOWING SNOW. AREA OF GREATEST CONCERN IS ALONG THE
BUFFALO RIDGE WHERE HIGHER ELEVATIONS WILL TAP INTO STRONGEST OF
WINDS ALOFT...AND THIS AREA ALSO RECEIVED GREATEST AMOUNT OF FRESH
SNOW OVER THE PAST 2-3 DAYS. AS MENTIONED IN SHORT TERM PORTION OF
THIS DISCUSSION...WILL NOT BE ISSUING ANY HEADLINES JUST YET...BUT
POTENTIAL THERE AND LATER SHIFTS MAY NEED TO CONSIDER.

ASIDE FROM BLOWING SNOW THREAT...BOTH NAM AND GFS HINTING AT
DEVELOPMENT OF STRATUS BELOW THE STRENGTHENING INVERSION EAST OF THE
JAMES VALLEY FRIDAY MORNING...TOPPED BY WEAK LIFT FROM THE BROAD WARM
ADVECTION. AT THIS TIME...FORECAST SOUNDINGS KEEP THE STRATUS LAYER
WITHIN THE SNOW GROWTH TEMPERATURE RANGE...SO HAVE ONLY ADDED CHANCE
OF FLURRIES FOR NOW. BUT WITH DRY AIR ABOVE THIS...IF ICE IS NOT
INTRODUCED WITHIN THE STRATUS LAYER ITSELF WE COULD BE LOOKING AT
SOME PATCHY FREEZING DRIZZLE INSTEAD.

FRIDAY NIGHT A LITTLE TRICKY WITH POST FRONTAL WAVE BRINGING A
CHANCE OF LIGHT PRECIPITATION TO MAINLY NORTHERN PORTIONS OF THE
AREA. ALAS...WITH THE WARMING AHEAD OF THE BOUNDARY...ESPECIALLY
ALOFT...QUESTIONS OF PRECIPITATION TYPE ENTER THE EQUATION. WITH ALL
MODELS CONTINUING TO SHOW A WARM LAYER ALOFT OF 3-6C AHEAD OF THE
FRONT IN THE EVENING...INTRODUCTION OF MIXED PRECIP TYPES BECAME
NECESSARY...AND WILL HAVE A MENTION OF FREEZING RAIN/SLEET ACROSS
MAINLY THE NORTH AND EAST BEFORE THE COLDER AIR PUSHES SOUTH AND
CHANGES ANY LINGERING PRECIP TO SNOW. SAVING GRACE IS THAT AMOUNTS
CURRENTLY LOOK TO REMAIN QUITE LIGHT...SO ANY ICING SHOULD BE
MINIMAL. THE MILD TEMPERATURES FRIDAY...ALONG WITH THIS THREAT OF
FREEZING PRECIP...ALTHOUGH RELATIVELY SMALL...DO THROW A WRENCH INTO
THE CONTINUED POTENTIAL FOR BLOWING SNOW AS THE WINDS PICK BACK UP
BEHIND THE BOUNDARY LATER FRIDAY NIGHT THROUGH SATURDAY. HOWEVER...
SINCE CONFIDENCE IS GREATER IN STRONG WINDS THAN IN ANY APPRECIABLE
ICING OCCURRING ATOP THE LIGHT SNOW PACK...WILL KEEP THE MENTION OF
BLOWING SNOW IN THROUGH THE DAY SATURDAY.

AS FAR AS TEMPERATURES THROUGH THE WEEKEND...LOOKS LIKE THEY WILL BE
ON A DOWNWARD SLIDE FROM FRIDAY NIGHT THROUGH MID MORNING MONDAY...
WITH THE POSSIBLE EXCEPTION OF SUNDAY MORNING/MIDDAY WHEN READINGS
MAY SEE A SLIGHT CLIMB AS DEEPER MIXING BEHIND THE WELL ADVERTISED
SECONDARY ARCTIC FRONT BRINGS DOWN NOT-QUITE-AS-COLD AIR. 02/00Z
GFS/ECMWF A LITTLE FASTER WITH THE SECOND BOUNDARY THAN PREVIOUS
RUNS...BUT STILL ON TRACK WITH 850MB TEMPERATURES AS COLD AS -28C TO
-33C SLIDING THROUGH THE FORECAST AREA LATE SUNDAY/SUNDAY NIGHT.
SHOULD ALSO BE FAIRLY WELL MIXED WITH DEEP NORTHWEST FLOW BEHIND THE
BOUNDARY...WITH SUSTAINED WINDS OF AT LEAST 15-20 MPH PRODUCING WIND
CHILL READINGS OF 35 TO 50 BELOW ZERO FOR SEVERAL HOURS SUNDAY NIGHT
INTO MONDAY.

MODELS A LITTLE SHARPER WITH MID/UPPER LEVEL WAVE ACCOMPANYING THE
ARCTIC PUSH...WHICH COULD BRING A QUICK SHOT OF LIGHT SNOW TO MAINLY
SOUTHWEST PORTIONS OF THE AREA SUNDAY. CURRENTLY LOOKING AT AMOUNTS
OF AN INCH OR LESS...WITH BETTER CHANCE OF MORE THAN A DUSTING IN
AREAS WEST OF THE JAMES RIVER. REMAINDER OF THE LONGER RANGE SHOULD
BE ON THE DRY SIDE...WITH WARMING TREND BEGINNING BY MIDWEEK. MODELS
DIFFER ON TIMING OF WARM UP SLIGHTLY...SO DID NOT STRAY FROM GENERAL
MODEL CONSENSUS FOR TEMPERATURES AT THIS RANGE JUST YET.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)
ISSUED AT 1123 AM CST THU JAN 2 2014

LIGHT WINDS AND VFR CONDITIONS EXPECTED THROUGH THE DAY. WINDS WILL
INCREASE TONIGHT AS A SOUTHERLY LOW LEVEL JET DEVELOPS...LOOKING AT
GUSTS IN THE 20 TO 30 KT RANGE AT OUR TAF SITES INTO TOMORROW
MORNING. THIS COULD RESULT IN SOME VISIBILITY REDUCTION IN BLOWING
SNOW AT THE TAF SITES...BUT THE BEST CHANCE OF THIS WILL BE ACROSS
SOUTHWEST MINNESOTA...SO WILL LEAVE OUT OF THE TAFS AT THIS TIME.
WILL BE CLOSE TO LOW LEVEL WIND SHEAR CRITERIA AS WELL TONIGHT...BUT
THINKING SURFACE WINDS STAY GUSTY ENOUGH TO KEEP US JUST BELOW. TOUGH
CALL ON WHETHER MVFR STRATUS MOVES IN TONIGHT AS WARMER AIR MOVES
INTO OUR VERY COLD LOW LEVELS. MODELS STRUGGLE WITH STRATUS
FORECASTING IN THESE COLD SITUATIONS. HOWEVER THERE APPEARS TO BE
ENOUGH OF A SIGNAL IN BOTH THE NAM AND GFS TO WARRANT AN
INTRODUCTION OF MVFR STRATUS INTO THE TAFS..MOVING IN FROM SOUTHWEST
TO NORTHEAST LATER TONIGHT INTO TOMORROW MORNING. BUT THIS REMAINS A
LOW CONFIDENCE SITUATION. COULD SEE SOME FLURRIES OUT OF THESE
CLOUDS...BUT NOTHING MAJOR EXPECTED.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST SOUTH DAKOTA...
SOUTHWEST MINNESOTA...NORTHWEST IOWA...AND NORTHEAST NEBRASKA.

.DAY ONE...TODAY AND TONIGHT

WINTER WEATHER...
ALTHOUGH WINDS ARE RELATIVELY LIGHT THIS MORNING...WITH AIR
TEMPERATURES IN THE TEENS BELOW ZERO...ANY LIGHT BREEZE WILL
PRODUCE A WIND CHILL EFFECT. WIND CHILL READINGS OF 20 BELOW TO
30 BELOW ZERO ARE EXPECTED IN AREAS ALONG AND EAST OF THE JAMES
RIVER VALLEY AT TIMES. INCREASING WINDS WILL PRODUCE SIMILAR WIND
CHILLS IN AREAS EAST OF THE JAMES RIVER TONIGHT.

THE INCREASING WINDS WILL ALSO PRODUCE AREAS OF BLOWING AND
DRIFTING SNOW...ESPECIALLY ALONG AND EAST OF THE BUFFALO RIDGE IN
SOUTHWEST MINNESOTA...WHERE WIND GUSTS OF 30 TO 35 MPH ARE
EXPECTED BY LATE TONIGHT.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

STRONG SOUTHERLY WINDS WILL CONTINUE TO BRING A THREAT OF BLOWING
SNOW TO AREAS EAST OF THE JAMES RIVER VALLEY FRIDAY. VISIBILITY
IN OPEN AREAS MAY BE REDUCED TO A HALF MILE OR LESS AT
TIMES...ESPECIALLY ALONG AND EAST OF THE BUFFALO RIDGE IN
SOUTHWEST MINNESOTA WHERE WIND GUSTS OF 30 TO 40 MPH ARE
POSSIBLE.

THERE IS A CHANCE OF LIGHT FREEZING RAIN OR SLEET IN AREAS MAINLY
NORTH OF INTERSTATE 90 FRIDAY NIGHT. ALTHOUGH PRECIPITATION
AMOUNTS WILL BE LIGHT...UNTREATED SURFACES MAY DEVELOP SLIPPERY
SPOTS.

AREAS OF BLOWING SNOW WILL AGAIN BE POSSIBLE LATE FRIDAY NIGHT
AND SATURDAY...AS WINDS TURN TO THE NORTHWEST AND INCREASE TO 20
TO 30 MPH. WIND CHILL READINGS IN THE 20S BELOW ZERO WILL RETURN
TO EAST CENTRAL SOUTH DAKOTA AND SOUTHWEST MINNESOTA SATURDAY
NIGHT.

EVEN COLDER AIR IS FORECAST TO PUSH INTO THE REGION SUNDAY NIGHT
AND MONDAY. THIS COLD AIR WILL BE ACCOMPANIED BY BREEZY
CONDITIONS...RESULTING IN THE POTENTIAL FOR A PROLONGED PERIOD OF
DANGEROUS WIND CHILL READINGS IN THE 30S AND 40S BELOW ZERO EARLY
NEXT WEEK. THE COLDEST WIND CHILLS ARE EXPECTED MONDAY
MORNING...WHEN SOME PARTS OF EAST CENTRAL SOUTH DAKOTA AND
SOUTHWEST MINNESOTA COULD SEE WIND CHILL VALUES OF 50 BELOW TO 55
BELOW ZERO.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY AND TONIGHT.
