Area forecast discussion, Apr 2, 12:37 PM CDT, 2 hours 49 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ABERDEEN SD
1237 PM CDT WED APR 2 2014
.UPDATE...
AVIATION DISCUSSION UPDATED BELOW FOR 18Z TAFS.
NARROW BAND OF LIFT MOVING ACROSS THE SOUTHWEST CWA. DRY AIR
ACROSS THE EAST IS UNDERCUTTING THIS FEATURE HOWEVER...SO WHILE
RETURNS ALOFT ARE IMPRESSIVE...THE EASTERN FRINGE IS EVAPORATING
BEFORE REACHING THE GROUND. FROM MURDO WEST IT LOOKS LIKE SNOW IS
BEING REALIZED THOUGH. MESOSCALE MODELS CONTINUE TO PUSH THIS
NORTH/NORTHEAST...AND EXPAND IN COVERAGE AS THE WAVE EJECTS INTO
THE NORTHER PLAINS AND THE FAVORABLE JET QUADRANTS REALIZE BETTER
ALIGNMENT. THE ONLY ISSUE WITH THESE MESOSCALE MODELS IS THE
DEGREE OF DRY AIR IS BEING OVERCOME RATHER QUICKLY...WHICH WILL BE
HARDER TO ACCOMPLISH IN THE REAL WORLD IF EXPERIENCE SERVES ME
RIGHT. THUS...REDUCED SNOW AMOUNTS ON THE EASTERN EXTENT.
ADDITIONALLY...THERE HAVE BEEN NO ADJUSTMENTS TO
HEADLINES/FORECAST FOR IMPENDING EASTERN CWA SYSTEM. 12Z NAM IS IN
GOOD AGREEMENT WITH THE PREVIOUS FORECAST...THOUGH THE LATEST
GFS IS NOW ON A MORE EASTWARDS TRACK. SIGNIFICANT SNOW POTENTIAL
STILL EXISTS FROM SOUTH CENTRAL SOUTH DAKOTA...TO THE NORTHEAST
INTO WESTERN MINNESOTA.
&&
.PREVIOUS DISCUSSION...
.SHORT TERM...TODAY THROUGH FRIDAY
VERY ACTIVE SHORT TERM FORECAST WITH TWO STORM SYSTEM AFFECTING
THE AREA. FIRST ONE IS TODAY. WATER VAPOR IMAGERY SHOWS SHORTWAVE
ENERGY ACROSS THE CENTRAL/NORTHERN ROCKIES AND THIS WILL MOVE
TOWARDS THE WESTERN DAKOTAS LATER TODAY. LIFT OUT AHEAD OF THIS
SYSTEM WILL PRODUCE LIGHT TO MODERATE SNOWFALL ACROSS WESTERN AND
CENTRAL SOUTH DAKOTA TODAY. BUFKIT SOUNDINGS REVEAL DECENT AMOUNTS
OF LIFT WITHIN THE SNOW GROWTH REGION ACROSS WESTERN AND CENTRAL
SOUTH DAKOTA. MODELS ARE PRETTY CONSISTENT WITH THEIR AREA OF
SNOWFALL TODAY OVER THE WESTERN HALF OF SOUTH DAKOTA...BUT THE
TRICKY PART OF THE FORECAST WILL BE DETERMINING JUST HOW FAR EAST
SNOWFALL WILL SPREAD AS OVERALL DYNAMICS ARE WEAKER THE FARTHER
EAST YOU GO. THE WESTERN CWA STANDS THE BEST CHANCE FOR
ACCUMULATING SNOW TODAY...WHICH WILL LIKELY AMOUNT TO 2 TO 4
INCHES FOR THE WEST RIVER COUNTIES. AMOUNTS WILL DROP OFF
CONSIDERABLY TOWARDS THE JAMES VALLEY AND POINTS EAST.
LATER TONIGHT...FORECAST RATHER TRICKY AS WELL AS GFS AND GEM ARE
A BIT MORE BULLISH WITH QPF BUT DONT REALLY SEE WHERE THIS IS
COMING FROM. MAIN ENERGY WITH TODAYS WAVE WILL HAVE DEPARTED INTO
NORTH DAKOTA FOR THE MOST PART AND WE WILL NOT YET BE SEEING THE
EFFECTS OF THE NEXT STORM SYSTEM SET TO ARRIVE ON THURSDAY. LIKE
THE DRIER EC SOLUTION FOR OVERNIGHT. FORESEE SOME AREAS OF LIGHT
SNOW/DRIZZLE BUT OVERALL AMOUNTS SHOULD BE LIGHT. IF
ANYTHING...THERE MAY BE MORE NOTICEABLE ACCUMS ACROSS THE NORTHERN
CWA TONIGHT WITH THE AFFECTS OF THE DEPARTING WAVE POSSIBLY BEING
FELT.
BIGGER ISSUE WILL BE THE MUCH STRONGER STORM SYSTEM THURSDAY
THROUGH FRIDAY...WHICH WILL PULL OUT INTO THE CENTRAL PLAINS AND
MOVE TOWARDS THE GREAT LAKES. MODELS HAVE ALL SHIFTED FARTHER
NORTH AND NOW PUT HEAVY SNOW ACROSS THE EASTERN COUNTIES. THE EC
ONCE AGAIN WAS THE FIRST TO SHOW A FURTHER NORTH TRACK AND WATCHED
THE OTHER MODELS FINALLY CATCH UP TO IT. LEANING HEAVILY ON THE EC
FOR THE ENTIRE FORECAST PACKAGE. THE 00Z NAM WAS THE CLEAR OUTLIER
BUT NOW THE NEW 06Z NAM IS STARTING TO TREND FARTHER NORTH AS
WELL. THIS PUTS THE EASTERN CWA UNDER THE GUN FOR POTENTIALLY
HEAVY SNOW...PERHAPS 6 INCHES OR GREATER. HAVE THEREFORE ISSUED A
WINTER STORM WATCH FROM THURSDAY MORNING THROUGH 18Z FRIDAY.
ADJUSTMENTS MAY BE NEEDED TO TIMING IF MODELS START TO SLOW THE
SYSTEM DOWN LIKE THEY TYPICALLY DO CLOSER TO THE EVENT FOR THESE
STRONGER SCALE STORMS. WINDS LOOK TO BE BREEZY/WINDY...BUT
CERTAINLY NOT AS STRONG AS THEY WERE DURING THE RECENT BLIZZARD.
MAY STILL BE ENOUGH TO PRODUCE LOW VSBY...BUT DONT SEE THIS BEING
AN ALL OUT BLIZZARD LIKE THE RECENT STORM THAT MOVED THROUGH.
OVERALL DYNAMICS LOOK PRETTY GOOD. MODERATE TO STRONG
FRONTOGENESIS DURING THE DAY THURSDAY. UPPER LEVEL JET MAX MOVES
OVERHEAD AS WELL WITH GOOD AMOUNTS OF DIVERGENCE SHOWING UP IN
MODELS. ISENTROPIC PLOTS SHOW NICE UPGLIDE AND PLENTY OF MOISTURE
WITH MODERATE SPEC HUMIDITY VALUES.
.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY
SFC HIGH PRESSURE BUILDS IN FRIDAY NIGHT WHILE A BROAD UPPER TROF
REMAINS OVER THE PLAINS. THERE WILL BE A SERIES OF SHORTWAVES
MOVING THROUGH THE UPPER TROUGH THROUGH THE START OF THE NEXT WORK
WEEK. ALLBLEND KEEPS IN SOME SLIGHT CHANCE POPS SUNDAY NIGHT
THROUGH MONDAY NIGHT. LET THOSE REMAIN FOR CONSISTENCY HOWEVER THE
ECMWF IS TRENDING DRY FOR THE DAKOTAS DURING THIS PERIOD WITH THE
SFC HIGH DIRECTLY OVERHEAD.
BY TUESDAY UPPER FLOW BECOMES NORTHWESTERLY. ON THE PLUS SIDE
THERE ARE NO EXPECTED WELL DEVELOPED LOW PRESSURE SYSTEMS THROUGH
THE ENTIRE PERIOD. TEMPERATURES WILL MODERATE OVER THE WEEKEND AND
MAY EVEN JUMP ABOVE NORMAL BY THE VERY END OF THE EXTENDED.

VFR CONDITIONS ARE EXPECTED TO GRADUALLY DETERIORATE ACROSS THE
REGION THIS AFTERNOON AND EVENING AS A BAND OF SNOW DEVELOPS AND
MOVES NORTHEAST OVER THE REGION. HOWEVER THERE IS SOME DRY AIR TO
OVERCOME WHICH WILL CONTRIBUTE TO SLOW LOWERING OF CIGS. VSBYS ARE
EXPECTED TO FALL INTO MVFR/IFR DURING SNOWFALL. MOST OF THE
ACCUMULATING SNOW SHOULD END BEFORE MIDNIGHT.
