AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1153 AM CST MON JAN 5 2015
.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 522 AM CST MON JAN 5 2015
MAIN FOCUS FOR THE SHORT TERM IS THE SNOW STORM EXPECTED TO AFFECT
THIS AREA FROM LATE MORNING INTO THIS EVENING. MODELS HAVE CONVERGED
TOWARD A SOLUTION THAT FAVORS A BAND OF HEAVIER SNOW FROM NEAR HURON
THROUGH SIOUX FALLS AND THEN TO SPENCER AND STORM LAKE IOWA. THE
ECMWF IS TYPICALLY MUCH LOWER THAN OTHER MODELS ON TOTAL QPF WHILE
THE GFS...AND TO A LESSER EXTEND THE 4 KM WRF-ARW ARE FARTHER SOUTH
BRINGING SIGNIFICANT SNOW TO SIOUX CITY AS WELL. WHILE WE DID HEDGE
HEAVIER SNOWFALL A LITTLE FARTHER TO THE SOUTH THAN SUGGESTED BY THE
NAM...ECMWF...AND WRF-NMM...DID KEEP THE HEAVIEST SNOWFALL NORTH OF
SIOUX CITY ALTHOUGH THE EVOLUTION OF THIS BAND WILL NEED TO BE
MONITORED DURING THE EARLY AFTERNOON AS A SHIFT SOUTH OF ONLY 30
MILES WOULD BRING 5 TO 7 INCHES INTO THE SIOUX CITY METRO AREA.
LITTLE HAS CHANGED IN THE OVERALL DYNAMICS. WATER VAPOR IMAGERY
SHOWS AN IMPRESSIVE WAVE OVER SOUTHERN ALBERTA POISED TO MOVE
SOUTHEAST QUICKLY THIS MORNING. 700 MB UPPER ANALYSIS SHOWS A FAIRLY
STRONG THERMAL GRADIENT DEVELOPING FROM MONTANA INTO SD WITH A 10 C
DIFFERENCE BETWEEN OMAHA AND ABERDEEN AT 00Z. THIS GRADIENT WILL
INTENSIFY OVER THE NEXT FEW HOURS WITH STRONG FRONTOGENESIS
EXTENDING FROM NEAR HURON INTO NORTHWEST IOWA. WHILE IT IS NOT
UNSTABLE ABOVE THE FRONTAL SURFACE...EPV VALUES ARE AROUND 0.10 PVU
WHICH SUPPORTS THE DEVELOPMENT OF A FAIRLY NARROW BAND OF MODERATE
TO HEAVY SNOW. AS THE WAVE APPROACHES...EXPECT THE FRONTAL
CIRCULATION TO RAPIDLY DEVELOP. SNOW SHOULD QUICKLY SATURATE FROM
THE CLOUD BASE TO THE SURFACE THIS MORNING WITH SNOW BEGINNING BY
MID MORNING IN THE JAMES VALLEY AND REACHING NORTHWEST IOWA AND
SOUTHWEST MN BY NOON. INITIALLY EXPECT THIS BAND TO BE SOMEWHAT
BROAD AND TO SPREAD NORTHEAST THROUGH THE MORNING. HOWEVER...AS
THE UPPER LEVEL WAVE APPROACHES...AN INTENSE BAND OF SNOW WILL
DEVELOP WITHIN THE BROADER AREA OF LIGHT SNOW BY LATE MORNING OR
EARLY AFTERNOON. VISIBILITIES WITHIN THIS BAND OF SNOW WILL BE
LESS THAN HALF A MILE WITH PERIODS OF LESS THAN ONE QUARTER MILE
VISIBILITY RESULTING IN SNOWFALL RATES OF 1 TO 1.5 INCHES PER
HOUR AT TIMES. SO CONDITIONS ARE EXPECTED TO RAPIDLY DETERIORATE
IN THE LATE MORNING AND EARLY AFTERNOON FROM NORTHWEST OF SIOUX
FALLS INTO NORTHWEST IOWA AND SOUTHWEST MINNESOTA. AS THE WAVE
MOVES THROUGH LATE THIS AFTERNOON AND EVENING...SNOW WILL DECREASE
IN INTENSITY AND THEN GRADUALLY END...BY 00Z ALONG AND WEST OF THE
JAMES RIVER...03Z ALONG I29...AND AROUND 06Z IN NW IA. SNOWFALL
WITHIN THIS BAND IS EXPECTED TO BE AROUND 6 INCHES WITH LOCAL
AMOUNTS OF 8 INCHES. THE HIGHEST AMOUNTS ARE MOST LIKELY IN
NORTHWEST IOWA. OUTSIDE THE HEAVY SNOW BAND...MOST AREAS WILL SEE
4 TO 6 INCHES OF SNOW WITH THE EXCEPTION OF SOUTH CENTRAL SOUTH
DAKOTA WHERE UP TO 3 INCHES IS EXPECTED.
ONE VARIABLE ON SNOWFALL AMOUNTS WILL BE SNOW RATIOS. ALL MODELS
INDICATE STRONG LIFT IN THE DENDRITIC GROWTH LAYER. AT THIS
POINT...EXPECTING SNOW RATIOS DURING THE AFTERNOON TO GENERALLY BE
FROM 16-19 TO 1 WITH THE HIGHEST RATIOS AROUND MARSHALL AND
BROOKINGS. BUT THE RANGE OF RATIOS FOR THIS EVENT EXTEND FROM 15:1
TO 23:1 SO THE CURRENT FORECAST IS ON THE LOW END OF THIS RANGE
...ESPECIALLY SOUTH OF I90. IF SNOW RATIOS FOR THE EVENT AVERAGE
20:1 OR HIGHER...THEN SNOWFALL COULD BE ANOTHER 1 TO 2 INCHES HIGHER
THAN FORECAST. TOWARD THE END OF THE EVENT...SNOW RATIOS WILL
INCREASE TO 20 TO 1 OR HIGHER AS DENDRITIC GROWTH ZONE DEEPENS
ALTHOUGH ONLY A FEW HUNDREDTHS OF AN INCH OF PRECIPITATION ARE
EXPECTED BY THAT POINT.
THE OTHER CONCERN IS WIND. LATEST INDICATIONS ARE THAT 925 MB WINDS
WILL BE 20 TO 30 KTS FROM THE SOUTHEAST DURING THE AFTERNOON WHICH
WOULD SUPPORT GUSTS UP TO 30 MPH...ESPECIALLY SOUTH OF I90. SO DID
INCLUDE PATCHY BLOWING SNOW THIS AFTERNOON. AS THE INVERTED TROUGH
MOVES LATE THIS AFTERNOON AND EVENING...WINDS WILL DECREASE BUT
SHOULD PICK UP AGAIN OVERNIGHT...ESPECIALLY IN THE MISSOURI VALLEY
WHERE GUSTS WILL AGAIN APPROACH 30 MPH. SNOW WILL HAVE ENDED BY THIS
TIME BUT THERE MAY STILL BE PATCHY BLOWING SNOW IN THE MISSOURI
VALLEY. AS THE RIDGE MOVES IN LATE TONIGHT...WINDS WILL ONCE AGAIN
SUBSIDE.
HAVE CONTINUED THE WINTER STORM WARNING BASICALLY NORTHEAST OF A
LINE FROM DE SMET SD TO PARKER SD TO IDA GROVE IOWA. ALSO ISSUED A
WINTER WEATHER ADVISORY FOR THE REMAINDER OF THE COUNTIES WITH THE
EXCEPT OF BRULE...CHARLES MIX AND GREGORY WHERE SNOWFALL WILL BE 3
INCHES OR LESS. THERE ARE INDICATIONS THAT LYON AND LINCOLN COUNTY
MN MAY SEE 4 OR 5 INCHES OF SNOW RATHER THAN 6. KEPT THE WARNING
GOING THERE SINCE RATIOS REMAIN SOMEWHAT UNCERTAIN AND THE BAND
COULD DEVELOP A LITTLE FARTHER NORTH THAN CURRENTLY FORECAST.
FOR THOSE PLANNING TRAVEL TODAY...DO NOT BE FOOLED BY THE QUIET
WEATHER EARLY THIS MORNING. CONDITIONS ARE EXPECTED TO RAPIDLY
DETERIORATE LATE THIS MORNING AND EARLY THIS AFTERNOON...ESPECIALLY
WITHIN THE WARNING. THIS WILL MAKE TRAVEL VERY DIFFICULT THIS
AFTERNOON AND EARLY THIS EVENING.
.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 522 AM CST MON JAN 5 2015
MAIN ISSUE IN THE LONGER RANGE WILL BE THE CONTINUED WELL BELOW
NORMAL TEMPERATURES. TUESDAY WILL SEE HIGHS IN THE SINGLE DIGITS TO
AROUND 10...BUT EXPECT A COLD FRONT TO BRING A REINFORCING SHOT OF
ARCTIC AIR INTO THE REGION TUESDAY NIGHT INTO WEDNESDAY. SOME WEAK
LIFT WITH THE WAVE AND FRONT TUESDAY AFTERNOON AND EVENING...BUT
QUITE A BIT OF DRY AIR IN THE LOWER LEVELS. THUS SHOULD NOT SEE MUCH
IN THE WAY OF SNOW...BUT COULD BE SOME FLURRIES...ESPECIALLY CENTRAL
SOUTH DAKOTA AND EAST NEAR THE MISSOURI RIVER. LOOKING AT LOWS IN
THE TEENS BELOW ZERO AND HIGHS STAYING BELOW ZERO OVER MUCH OF THE
AREA ON WEDNESDAY. GIVEN THE COLD AIR ADVECTION AND 30 TO 35 KTS OF
WIND AT 925MB...MUCH OF THE GUIDANCE IS LIKELY TOO LOW WITH WINDS
TUESDAY NIGHT. THINKING WE WILL SEE 20 TO 30 MPH WINDS WITH SOME
HIGHER GUSTS. THE LOWEST WIND CHILLS OF THIS COLD SNAP THUS APPEAR
LIKELY LATER TUESDAY NIGHT INTO WEDNESDAY MORNING. AREAS ALONG AND
NORTHEAST OF A HURON TO SIOUX FALLS TO STORM LAKE LINE SHOULD SEE
VALUES BETWEEN -35 AND -40...AND THUS A WIND CHILL WARNING MAY END
UP BEING NEEDED IN THAT AREA...WITH AN ADVISORY ELSEWHERE. GIVEN THE
SNOW TODAY AND WINDS TUESDAY NIGHT...PATCHY BLOWING SNOW MAY ALSO
BECOME AN ISSUE.
HIGH PRESSURE SHIFTS OFF TO THE EAST WEDNESDAY NIGHT...WITH RETURN
SOUTHERLY FLOW QUICKLY INCREASING AHEAD OF OUR NEXT WAVE. THUS
EXPECT AN EVENING DROP IN TEMPERATURES BACK INTO THE TEENS BELOW
ZERO...BEFORE WE SEE RISING TEMPERATURES THE REMAINDER OF THE NIGHT.
WILL LIKELY NEED ANOTHER WIND CHILL ADVISORY ACROSS THE CWA.
SOUTHERLY WINDS WILL BE QUITE BREEZY BY LATE NIGHT. COULD SEE A BIT
OF LIGHT SNOW EAST OF THE BUFFALO RIDGE AHEAD OF THE WAVE...BUT MOST
OF THE LIGHT SNOW SHOULD STAY NORTHEAST OF THE CWA. WAVE AND COLD
FRONT THEN CROSS ON THURSDAY...WITH WINDS TURNING TO THE NORTHWEST
AND INCREASING. GIVEN THE CAA AND 925 MB WINDS POTENTIALLY OF 35 TO
45 KTS...WENT AHEAD AND INCREASED WINDS IN THE FORECAST. WILL
PROBABLY BE NEAR ADVISORY CRITERIA THURSDAY AFTERNOON AND EVENING.
WILL HAVE TO MONITOR THE STATE OF THE SNOWPACK...AS BLOWING SNOW
COULD BECOME AN ISSUE. THURSDAY WILL BE ONE OF THE WARMER DAYS OF
THE WEEK...WITH TEENS AND 20S...HOWEVER READINGS WILL CRASH RIGHT
BACK INTO THE SINGLE DIGITS ABOVE AND BELOW ZERO BY EVENING INTO THE
OVERNIGHT BEHIND THE FRONT. THEN ON FRIDAY WILL ONLY REBOUND INTO
THE SINGLE DIGITS ABOVE ZERO. ADDITIONAL WIND CHILL ADVISORIES WILL
PROBABLY BE NEEDED THURSDAY NIGHT.
MODEL SPREAD INCREASES SOME BY THE WEEKEND. STILL WILL LIKELY STAY
BELOW NORMAL WITH HIGHS IN THE TEENS OR LOW 20S AND LOWS EITHER SIDE
OF ZERO. HOWEVER MODELS DIFFER ON TIMING OF WEAK WAVES MOVING EAST
ACROSS THE PLAINS AND AVAILABLE MOISTURE. FOR NOW WILL KEEP LOW POPS
IN FOR SATURDAY. LATEST GFS AND ECMWF ARE DRY...BUT THE
GEM...PARALLEL GFS AND EARLIER RUN OF THE ECMWF SUGGESTED A LIGHT
SNOW POTENTIAL.
&&
.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 1152 AM CST MON JAN 5 2015
SNOW BAND BECOMING ESTABLISHED ACROSS THE AREA WITH WIDESPREAD
VISIBILITIES OF 1/2 TO 1SM. LIFR OR WORSE WILL BE THE RULE THE
NEXT 3-6 HOURS...BUT SHOULD IMPROVE QUICKLY IN TERMS OF VISIBILITY
AND CEILING LATER IN THE AFTERNOON AND EARLY EVENING FROM WEST TO
EAST. WINDS LOOK POTENTIALLY A BIT LIGHT IN GUIDANCE FOR
LOCATIONS WEST OF THE INVERTED TROUGH DURING THE EVENING AND EARLY
OVERNIGHT MAINLY FROM THE JAMES THROUGH MISSOURI RIVER CORRIDORS.
DOUBTS AS TO IF WINDS WOULD BE STRONG ENOUGH TO PRODUCE ANY
APPRECIABLE BLOWING SNOW...BUT KSUX WOULD BE THE GREATEST RISK FOR
ANY TAF LOCATION.
