AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ABERDEEN SD
1154 AM CST MON JAN 11 2016

.UPDATE...
ISSUED AT 1018 AM CST MON JAN 11 2016

A WEAK SHORTWAVE CURRENTLY OVER NORTH DAKOTA...WILL TRACK
SOUTHEASTWARD ACROSS THE EASTERN HALF OF THE CWA THIS AFTERNOON.
REGIONAL RADARS ARE SHOWING LIGHT SNOW OVER MUCH OF NORTH
DAKOTA...WHICH SHOULD PUSH INTO THIS CWA AROUND NOON. THIS SHOULD
BE A HIGH POP/LOW QPF EVENT AS SEVERAL OBS IN NORTH DAKOTA ARE
ONLY REPORTING A TRACE OF PCPN. PATCHING BLOWING SNOW LOOKS
POSSIBLE THIS AFTERNOON AS THE WINDS INCREASE TO 15 TO 25 MPH.

&&

.SHORT TERM...(TODAY THROUGH WEDNESDAY AFTERNOON)
ISSUED AT 352 AM CST MON JAN 11 2016

WEAK SHORTWAVE CURRENTLY MOVING SOUTHEAST ACROSS THE AREA. SEEING A
FEW PATCHES OF LIGHT SNOW DRIFTING SOUTHEAST AS WELL...JUST NOW
ENTERING NORTHERN SD. HAVE INCLUDED SOME SMALL POPS FOR THE NEXT FEW
HOURS AS THIS ENERGY MOVES THROUGH. VSBY IN KBIS WAS DOWN EARLIER
AND K7L2 STATION NORTH OF KMBG WAS REPORTING -SN EARLIER AS WELL.
WARM FRONT IS SET UP ACROSS WESTERN SD THIS MORNING WITH SHARP
TEMPERATURE CONTRAST NOTED IN OBS. 30 DEGREES IN KPHP WHILE KPIR IS
STILL 11.

LOW PRESSURE ALONG WITH WARM/COLD FRONT WILL ALL TRACK EAST-
SOUTHEAST ACROSS THE AREA TODAY. PUSH OF WARM AIR WILL MAKE IT CLOSE
TO THE JAMES VALLEY BEFORE BEING PUSHED SOUTHWARD AS THE PUSH OF
COLD AIR MOVES IN. HAVE DECREASED HIGHS OVER THE NORTHEAST CWA WHERE
WARMER AIR NEVER MAKES IT. COULD STILL SEE SOME LIGHT SNOW ACROSS
THE REGION AS WELL...BUT NOW IT APPEARS THE BEST CHANCE FOR THIS
WILL BE ACROSS THE FAR EASTERN CWA. ANOTHER SURGE OF ARCTIC AIR WILL
MOVE SOUTHWARD INTO THE AREA TONIGHT...BEHIND THE COLD FRONT.
TEMPERATURES WILL TANK AS 925 MB TEMPS FALL TO NEAR -20 DEGREES
CELSIUS ONCE AGAIN OVER THE FAR EASTERN CWA. WINDS WILL BECOME
BREEZY/GUSTY BEHIND THE FRONT LATER THIS AFTERNOON AND THIS EVENING
SO HAVE ADDED PATCHY BLOWING SNOW. THESE WINDS WILL PERSIST ACROSS
THE EASTERN CWA OVERNIGHT WHILE TEMPERATURES DROP BELOW ZERO. WIND
CHILL VALUES WILL FALL TO AROUND 25 BELOW ZERO SO A WIND CHILL
ADVISORY MAY BE NECESSARY. DID NOT ISSUE ANYTHING AT THIS POINT DUE
TO THE MARGINALITY OF EVENT AND THE UNCERTAINTY OF LINGERING CLOUD
COVER TONIGHT. IF CLOUDS LINGER ACROSS THE EAST...TEMPS/WIND CHILLS
WILL END UP BEING WARMER THAN FORECAST.

TEMPS LOOK TO REBOUND BY WEDNESDAY AS WARMER LOW LEVEL AIR AND
WESTERLY WINDS SPREAD OVER THE REGION. HIGHS ARE EXPECTED TO BE IN
THE 20S AND 30S FOR MOST LOCATIONS.

.LONG TERM...(WEDNESDAY EVENING THROUGH SUNDAY)
ISSUED AT 352 AM CST MON JAN 11 2016

THE STRONGLY MERIDIONAL PATTERN OF LATE GOES THROUGH A BIT OF A DE-
AMPLIFICATION EARLY IN THE PERIOD AS ENERGY FLOWS INTO THE WEST
COAST AND CRUSHES THE WESTERN CONUS RIDGE. HOWEVER...MOST OF THAT
ENERGY RIDES ACROSS THE SOUTHERN CONUS.  THE WESTERN CONUS RIDGE
REBOUNDS QUICKLY AS A PIECE OF THE EASTERN CANADA VORTEX DROPS SOUTH
INTO THE NORTHERN PLAINS.  THE ECMWF/GEM ARE MUCH MORE AGGRESSIVE
WITH THIS FEATURE MOVING SOUTH VS THE GFS...AND ARE THEREFORE MUCH
COLDER...WITH H85 TEMPS IN THE -25C RANGE BY SATURDAY.  GIVEN SOME
CONSISTENCY IN THE COLDER ECMWF...DID START THE TREND OF LOWERING
TEMPS FROM THE TOO MILD MODEL SUPER BLEND OVER THE UPCOMING
WEEKEND...BOTH HIGHS AND LOWS. AS FOR PCPN CHANCES...PROBABLY THE
BEST POTENTIAL FOR ANY MEASURABLE SNOW WILL BE THURSDAY NIGHT AND
FRIDAY AS THE INITIAL SURGE OF ARCTIC AIR BEGINS ACROSS THE FORECAST
AREA. HOWEVER...AM STILL NOT EXPECTING TOO MUCH IN THE WAY OF
ACCUMULATION AT THAT TIME.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 1142 AM CST MON JAN 11 2016

ANOTHER WEAK SHORTWAVE IS MOVG SWD THRU ND DURING THE MIDDAY HOURS
TODAY CREATING -SN ACROSS REPORTING STATIONS IN ND. EXPECTING
THIS -SN TO MOVE INTO SD AND ACROSS ALL OUR LOCAL TAF SITES THIS
AFTN INTO THIS EVENING. INCREASING NW WINDS WILL ACCOMPANY THIS
-SN AND REMAIN BREEZY THRU THIS EVENING. LOW END MVFR CIGS ARE
ANTICIPATED TO PREVAIL INTO THE EARLY OVRNGT BEFORE TRANSITIONING
TO VFR. KEPT VFR VSBYS IN THIS FCST ISSUANCE BUT A PERIOD OF MVFR
VSBYS IS POSSIBLE IN FALLING -SN AND GUSTY WINDS.
