AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1114 AM CST SAT FEB 1 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 336 AM CST SAT FEB 1 2014

ONGOING SNOWFALL IN OUR SOUTHEAST AND SUBSEQUENT TEMPERATURE TRENDS
ARE MAIN FOCUS FOR THE NEXT 24 HOURS. AS OF 09Z...SNOW IS CONFINED
TO OUR EXTREME SOUTHEAST SD/NORTHEAST NE/NORTHWEST IA COUNTIES...WITH
PERHAPS JUST A FEW FLURRIES FROM LIGHT ECHOES SEEN FARTHER NORTHWEST
TOWARD SIOUX FALLS AND INTO SOUTHWEST MN WHERE CEILINGS ARE STILL
LARGELY 6KFT OR HIGHER. BACK EDGE OF PRECIP MAKING STEADY PROGRESS
EASTWARD THROUGH EASTERN NEBRASKA...AND ANTICIPATE ANY POTENTIAL FOR
LIGHT ACCUMULATIONS WILL BE EAST OF OUR CWA BY 14Z-15Z. WIDESPREAD
CLOUD COVER SHOULD FOLLOW SUIT WITH AT LEAST PARTIAL CLEARING BEHIND
THE DEPARTING WAVE. SHOULD SEE SOME STRATOCU DEVELOPMENT AS COLD AIR
SETTLES IN THIS AFTERNOON/EARLY EVENING...AND SOME FORECAST SOUNDINGS
SHOW POTENTIAL FOR A FEW FLURRIES WITH THIS MOISTURE LAYER IN THE
FAVORED TEMPERATURE RANGE...BUT CONFIDENCE IN ANY FLURRY DEVELOPMENT
IS LOW SO HAVE NOT INCLUDED AT THIS TIME.

COLD FRONT HAS PUSHED THROUGH WESTERN 1/3 OF THE CWA...AND JUST
STARTING TO SEE EFFECTS OF COLD ADVECTION AT K9V9 AND KHON AT 09Z.
FRONT EXPECTED TO BE NEAR I-29 BY 12Z AND EAST OF THE CWA BY 16Z-17Z.
COLD ADVECTION CONTINUES ACROSS THE CWA THROUGH THE DAY...STRONGEST
IN THE WEST THIS MORNING AND EAST THROUGHOUT THE AFTERNOON. THUS
ANTICIPATE EARLY MORNING HIGHS IN THE WEST WITH SOME STEADYING THERE
IN THE AFTERNOON...WHILE SOUTHEAST AREAS COULD STILL SEE READINGS
CLIMB A FEW DEGREES YET PRIOR TO 18Z...FOLLOWED BY THE FALLING TEMPS
IN THE AFTERNOON. NORTHWEST WINDS WILL BECOME GUSTY WITH POST-FRONTAL
MIXING...THOUGH ONLY TOPPING OUT 25 TO 30 MPH MOST AREAS. WITH FAIRLY
LIGHT SNOWFALL ACCUMULATIONS FROM THE EARLY MORNING...DO NOT EXPECT
THE WINDS WILL CAUSE ANY VISIBILITY ISSUES IN BLOWING SNOW...THOUGH
SOME DRIFTING CERTAINLY POSSIBLE IN OPEN AREAS.

TEMPERATURES WILL CONTINUE TO FALL THROUGH THE NIGHT...WITH WINDS
BECOMING FAIRLY LIGHT AS SURFACE RIDGE MOVES IN. STILL ENOUGH WIND IN
OUR NORTHEAST TO PUSH WIND CHILL VALUES INTO 20S BELOW ZERO AS TEMPS
DROP BELOW ZERO LATE TONIGHT. AFTER COORDINATION WITH NEIGHBORING
OFFICES...OPTED TO HOLD OFF ON ANY WIND CHILL HEADLINES FOR NOW...BUT
WILL CONTINUE MENTION IN THE HWO THIS MORNING.

.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 336 AM CST SAT FEB 1 2014

SUNDAY AND SUNDAY NIGHT SHOULD BE PRETTY CLEAR AS HIGH PRESSURE OVER
THE AREA MOVES SLOWLY EAST. MONDAY WILL SEE CLOUDS INCREASE AS SHORT
WAVES IN WEAKLY SPLIT FLOW APPROACH FROM THE WEST SOUTHWEST.
TEMPERATURES SHOULD DO SOME WARMING AND ON BOTH DAYS SHOULD BE
FAIRLY CLOSE TO NORMAL. IN FACT...THE PATTERN APPEARS TO BE
UNDERGOING A REAL CHANGE WHICH WILL MODIFY THE WILD TEMPERATURE
SWINGS WE HAVE HAD MUCH OF THE WINTER. THIS WOULD MEAN LESS OF THE
EXTREME COLD PERIODS AND NONE OF THOSE BRIEF BALMY INTERLUDES FOR A
WHILE. STILL...WE ARE LIKELY TO GET SOME PERIODS OF FRIGID WIND
CHILL DURING THE COMING WEEK BEHIND THE TUESDAY WAVES...AFTER THEY
PRODUCE AREAS OF LIGHT SNOW...ESPECIALLY IN THE SOUTHERN PART OF OUR
AREA. IT JUST WILL NOT BE AS BAD AS A COUPLE OF OUR RECENT EPISODES.
WEDNESDAY SHOULD BE OUR COLDEST DAY WITH SOME FRIGID WIND CHILLS
LIKELY NORTH AND EAST FROM TUESDAY NIGHT THROUGH THURSDAY MORNING.
CANADIAN HIGH PRESSURE WILL BE MOVING TOWARD AND INTO THE AREA
DURING THAT TIME AND THE WEATHER SHOULD BE DRY.

THE NEXT POSSIBLE SYMPTOM OF THE PATTERN CHANGE COULD BE A CHANCE OF
A MORE SIGNIFICANT SNOW SYSTEM...AS FAR AS ACCUMULATIONS GO THAT IS.
THIS WOULD COME NEAR THE END OF THE FORECAST PERIOD LATE NEXT
WEEK...OR POSSIBLY THE FOLLOWING WEEKEND. THE GFS FAILS TO DIG
DEVELOPING WESTERN TROUGH VERY MUCH AND SHOWS LITTLE EXCITEMENT. THE
EC AND GEM ARE MORE INTERESTING...THOUGH THE EC APPROACHES A BROAD
SYSTEM BY FRIDAY WITH MEAGER THERMAL CONTRAST AND NOT TOO MUCH SNOW
POTENTIAL. THE GEM/CANADIAN THROUGH H144 SHOWS MORE POTENTIAL BUT
THE LATER TIME STEPS OF THIS MODEL HAVE BEEN UNAVAILABLE SO FAR
TONIGHT. WILL GO FOR A FAIRLY LOW CHANCE OF SNOW AT THIS TIME FOR
FRIDAY AND FRIDAY NIGHT. IN ANY EVENT...WARMING AT THE END OF THE
WEEK FROM THE MIDWEEK COLD WILL PROBABLY BE MODEST. THE GFS WITH ITS
LACK OF DIGGING WOULD INDICATE BETTER WARMING BUT FEEL HERE THAT
THIS SOLUTION IS LESS LIKELY THAN THE OTHERS TO VERIFY. WOULD NOT BE
SURPRISED TO SEE IT TREND TO THE BETTER DIGGING SOLUTION THIS TIME
TOMORROW.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)

GENERALLY EXPECTING VFR CONDITIONS THROUGH THE PERIOD. COULD STILL
SEE SOME STRATOCU DEVELOPMENT IN THE MVFR RANGE...BUT NOT SEEING
ANYTHING OUT THERE YET. THUS REMOVED THE TEMPO GROUPS...BUT WILL
CONTINUE TO MONITOR THROUGH THE AFTERNOON. ANY LOWER CLOUDS WILL
QUICKLY DISSIPATE BY SUNSET. OTHERWISE...NORTHWESTERLY WINDS GUSTING
TO AROUND 25 KTS WILL CONTINUE THROUGH THIS AFTERNOON...BEFORE
DISSIPATING TONIGHT.
