AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ABERDEEN SD
323 PM CST TUE NOV 27 2007

.SHORT TERM...TONIGHT THROUGH THURSDAY
WIND AND TEMPS ROUND OUT THE MAIN ISSUES THROUGH THIS TIME RANGE.
PER WATER VAPOR IMAGERY...OPEN MID LEVEL TROF IS CURRENTLY MOVING
THROUGH THE ROCKIES WITH ANOTHER WAVE TRACKING SOUTHEAST THROUGH
THE CASCADES. MEANWHILE SURFACE LOW PRESSURE IS FORMING IN THE
LEE OF THE ROCKIES...AND AS ENERGY OVER THE CASCADES HEADS ACROSS
THE ROCKIES AND INTO THE PLAINS...WE SHOULD SEE THE SOUTHERN SFC
LOW TAKE OVER IN NORTHEAST COLORADO. AHEAD OF THIS FEATURE IT
REMAINS PRETTY DRY IN THE LOWER TROPOSPHERE. SO...DESPITE FAIRLY
STRONG JET/SYNOPTIC SCALE LIFT/STEEP MID LEVEL LAPSE RATES...THE LACK
OF MOISTURE PRECLUDES ANYTHING ABOVE A SLIGHT CHANCE MENTION OF
SNOW SHOWERS TNT INTO WEDNESDAY. THE MAIN ISSUE WILL BE THE
DEVELOPING WINDS LATE TNT AND WEDNESDAY. STRONG CAA AND DOWNWARD
MOTION ACROSS THE REGION ON WEDNESDAY SHOULD ALLOW FOR A WELL
MIXED ENVIRONMENT...AND A LINK TO STRONG WINDS ALOFT. WIND
ADVISORY HAS BEEN ISSUED TO COVER THE EVENT FOR THE ENTIRE CWA
BEGINNING EARLY MORNING WEST...AND ENDING ACROSS ENTIRE CWA BY
00Z. LASTLY...WEAK WAVE COULD BRING ADDED CLOUDINESS TO THE CWA ON
THURSDAY INTO THURSDAY NIGHT. FOR NOW IT AGAIN LOOKS TOO DRY FOR
MEASURABLE PCPN SO NO MENTION IN THE GRIDS.

CONCERNING TEMPERATURES...LL WAA TNT SHOULD KEEP TEMPERATURES FROM
FALLING OFF TOO MUCH...THEY MAY IN FACT STAY STEADY FOR GOOD
PORTION OF THE EVENING. THEN WE TURN AROUND TO STRONG CAA ON
WEDNESDAY AND GOOD MIXING WHICH MAY IN FACT CAUSE FALLING
TEMPERATURES IN THE MORNING...WITH ONLY A VERY SLIGHT RECOVERY IN
THE AFTERNOON. WEDNESDAY NIGHT SHOULD BE SOMEWHAT CHILLY AS WINDS
DIMINISH ALONG WITH SOME BREAKS IN THE CLOUD COVER. POOR MIXING
WILL LIKELY KEEP TEMPERATURES BELOW NORMAL FOR THURSDAY.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY NIGHT
PRIMARY EXCITEMENT IN THE LONG RANGE INVOLVES A POTENTIAL SNOW
EVENT THIS WEEKEND ACROSS THE CWA. TEMPERATURES...PARTICULARLY
FOLLOWING THIS POSSIBLE FIRST REAL WINTER STORM OF THE
SEASON...ARE CHALLENGING TO PINPOINT...BUT WITH THE POSSIBLE EXCEPTION
OF SATURDAY...STILL APPEAR TO BE BELOW NORMAL THROUGHOUT THE
EXTENDED RANGE.

THE 12Z RUNS OF THE GFS/ECMWF/GFS ENSEMBLES/UKMET/GEM/NOGAPS HAVE
COME INTO BETTER AGREEMENT ON A FASTER EASTWARD...AND MORE
NORTHWARD...PROGRESSION OF A TROUGH DIGGING INTO THE WESTERN CONUS
ON FRIDAY. PRETTY MUCH EVERY INDIVIDUAL GFS ENSEMBLE MEMBER AGREES
QUITE WELL WITH THIS AS WELL. THE 12Z ECMWF IS STILL 12 TO 24
HOURS SLOWER THAN THE GFS...BUT MUCH FASTER THAN THE 00Z RUN HAD
SHOWN. ENERGY WAS NOTED WITH THE 00Z ECMWF RUN THAT DOVE STRAIGHT
SOUTH FROM THE NORTH POLE AND DUG JUST OFF THE WEST COAST TO
REINFORCE THE WESTERN TROUGH AND SLOW IT DOWN. THAT SAME ENERGY IS
PRESENT ON THE 12Z RUN...BUT THE WESTERN TROUGH HAS MADE ENOUGH
EASTWARD PROGRESSION BY 00Z SUNDAY...WHEN THE ENERGY REACHES THE
PACIFIC NORTHWEST...THAT IT IS UNABLE TO REINFORCE THE TROUGH AND
THUS DIG IT DEEPER. GIVEN THE BETTER AGREEMENT AMONG THE 12Z
RUNS...HAVE BEGUN TO LEAN A BIT TOWARD A QUICKER AND FURTHER NORTH
SOLUTION TO THE LIFTING OF THE TROUGH/ASSOCIATED SURFACE LOW FROM
THE WEST...BUT WITH TIMING AND SOME LOCATION DIFFERENCES STILL
PRESENT...POPS REMAIN RELATIVELY LOW AT THIS TIME UNTIL BETTER
AGREEMENT IS REACHED.

AS SURFACE HIGH PRESSURE SLIDES ACROSS THE NORTHERN PLAINS ON
FRIDAY...PACIFIC ENERGY DIVES INTO THE NORTHWEST AND CARVES OUT A
TROUGH IN THE WESTERN CONUS...MERGING WITH AN UPPER LOW THAT BY
THIS TIME HAD BEEN SPINNING OFF THE BAJA CALIFORNIA COAST DURING
THE ENTIRE SHORT TERM...KICKING IT OUT TO THE NORTH AND EAST INTO
THE SOUTHWEST CONUS. THE ASSOCIATED SURFACE LOW LIFTS OUT AS
WELL...MOVING INTO COLORADO BY FRIDAY NIGHT...THOUGH AS NOTED THE
12Z GFS IS A BIT FASTER THAN THE 12Z ECMWF. AGREEMENT THEN EXISTS
IN MOVING THE LOW NORTHEAST THROUGH KANSAS...IOWA/MISSOURI...AND
ILLINOIS THROUGH THE WEEKEND...BECOMING A 980MB OR SO LOW NEAR
LAKE HURON BY MONDAY MORNING. WITH A MOISTURE SOURCE INITIALLY FROM
THE TROPICAL PACIFIC OFF THE MEXICAN COAST...THEN ALSO FROM THE
GULF OF MEXICO AS THE STORM MOVES TO THE EAST/NORTHEAST...MOIST
AIR OVERRUNNING IS PLENTIFUL...PARTICULARLY TO OUR SOUTHEAST IN
EASTERN NEBRASKA/KANSAS AND IOWA/MISSOURI. THE GFS BRINGS SNOW
FROM THIS FURTHER NORTH TO THIS CWA THAN THE ECMWF...BUT DUE TO
THE DIFFERENCES...KEPT POPS LOW NEAR 20 ON SATURDAY. IF THE GFS
SOLUTION BEGINS TO LOOK MORE LIKELY...POPS WILL NEED TO BE RAISED
AS IT SUGGESTS 2 TO 7 INCHES OF SNOW ACROSS THE CWA ON SATURDAY
AND 90 PERCENT OF GFS ENSEMBLE MEMBERS DROP AT LEAST 0.05 INCHES
QPF OVER THIS CWA ON SATURDAY. THE 12Z ECMWF BRINGS QPF INTO THE
CWA SATURDAY NIGHT ON THE NORTHWEST SIDE OF THE LOW...AND THEN
THROUGH SUNDAY ACROSS THE EASTERN CWA AS WRAPAROUND SNOW TAKES
CONTROL WITH THE 986-991MB LOW RESIDES IN THE SOUTHERN GREAT LAKES
REGION BY SUNDAY EVENING...BUT THE GFS MOVES THE STORM A BIT
FURTHER EAST...KEEPING WRAPAROUND SNOW FURTHER EAST THAN THE
ECMWF. EITHER WAY...CONTINUED AND RAISED POPS A BIT FOR SATURDAY
NIGHT AND INTRODUCED SOME LOW POPS IN THE EASTERN CWA FOR
SUNDAY...UNTIL TIMING OF THIS SYSTEM CAN BE MORE ACCURATELY
DETERMINED. IF THE GFS/ECMWF/GFS ENSEMBLES ARE ON THE RIGHT TRACK
WITH THIS SYSTEM...POPS WILL HAVE TO BE RAISED FURTHER AS THE WEEK
GOES ON.  THIS SYSTEM WILL CONTINUE TO BE MONITORED.

AS FOR TEMPERATURES...WARMER TEMPERATURES THAN OBSERVED RECENTLY
LOOK PROBABLE ON SATURDAY AS SOUTHEASTERLY FLOW AHEAD OF THE
APPROACHING SYSTEM BRINGS WARMER AND MORE HUMID AIR INTO THE
AREA...WITH 850MB TEMPERATURES RISING TO NEAR -5 C BY SATURDAY
MORNING...BUT THIS WILL OF COURSE BE TEMPERED BY CLOUD COVER
ADVANCING INTO THE REGION. PRECIPITATION SHOULD REMAIN ALL SNOW AS
WE REMAIN FAR ENOUGH TO THE NORTH OF THE SYSTEM AND 1000-500MB
THICKNESSES REMAIN BELOW 537 DAM THROUGHOUT THE DURATION OF THE
IMPACT OF THE SYSTEM. FOR SUNDAY INTO MONDAY...ESPECIALLY SUNDAY
NIGHT...COLD AIR FLOWS SOUTH ON THE BACKSIDE OF THE DEEPENING
980MB LOW IN SOUTHERN ONTARIO. WITH 850MB TEMPERATURES AT LEAST IN
THE MID TEENS BELOW ZERO...THE 12Z NOGAPS SUGGESTS -21 TO
-24C...A HIGH PRESSURE AXIS OVER THE CWA...AND POSSIBLY FRESH SNOW
COVER...MONDAY MORNING COULD BE QUITE COLD ACROSS THE AREA. ANY
SNOW AND HOW LOW IT REACHES MONDAY MORNING WILL ALSO INFLUENCE
MONDAY AFTERNOON HIGH TEMPERATURES.
