AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ABERDEEN SD
922 PM CST FRI FEB 23 2007

.UPDATE...
MODELS ARE CONT TO ADVERTISE A SLOW DEVELOPMENT OF PCPN ACROSS
CWA. CURRENTLY NOTHING ON RADAR...AND CIGS FOR THE MOST PART ARE
STILL LOW VFR. HAVE PUSHED BACK ONSET OF PCPN...AND DROPPED DOWN
TO CHC CATEGORY FOR ALL AREAS TOWARD MORNING. LATEST NAM SHOWING
THAT SATURDAY AFTN/NIGHT ARE STILL BIG TIMES FOR SNOWFALL...AND
SEE NO REASON TO FIDDLE WITH WARNING CURRENTLY IN PLACE.

&&
.PREV DISCUSSION...
.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT
SATURATION IN THE LOWER LEVELS FINALLY SHOWING SIGNS OF STARTING
LATE THIS AFTERNOON AS CEILINGS ARE DROPPING TO AROUND 3000 FT FOR
MANY LOCATIONS. STORM SYSTEM A BIT SLOWER TO MATERIALIZE AND HELD
OFF PRECIP UNTIL AFTER MIDNIGHT AND CHANGED THE START TIME FOR THE
WARNING TO MIDNIGHT ALSO. JET STREAK NOTED THIS AFTERNOON ROUNDING
THE BASE OF THE TROUGH AND MOVING NORTHEAST THROUGH THE CENTRAL
PLAINS. THIS MAY AID IN PRECIP DEVELOPMENT LATER TONIGHT. SYSTEM
APPEARS TO BE A LITTLE WARMER INITIALLY SO ADDED MORE LIQUID
PRECIP TO THE FORECAST FOR THE CENTRAL AND EASTERN CWA. CHANGEOVER
SHOULD OCCUR FROM WEST TO EAST BEGINNING LATE TONIGHT AND THROUGH
TOMORROW MORNING. MOST LOCATIONS SHOULD BE ALL SNOW BY 18Z
SATURDAY. STILL LOOKING AT AMOUNTS AROUND 6 TO 10 INCHES ACROSS
THE EAST...TAPERING OFF TO 5 TO 8 AROUND THE PIERRE AREA...TO ONLY
A COUPLE INCHES AT BEST ACROSS THE NORTH CENTRAL PORTION OF THE
STATE. THIS WILL HAVE TO BE FIGURED AGAIN ONCE PRECIP FORMS AND
MOVES INTO THE AREA...AND ONCE A RAIN/SNOW LINE CAN BE DETERMINED
AND TRACKED. IN GENERAL...A VERY DIFFICULT FORECAST THIS AFTERNOON
AND WILL HAVE TO CONSTANTLY MONITOR FOR CHANGES AND UPDATES. THERE
APPEARS TO BE A RATHER SHARP CUTOFF FOR HEAVIER SNOW VS LIGHTER
SNOW SOMEWHERE ACROSS CENTRAL SD SO THIS BRINGS HAVOC INTO THE
SNOWFALL FORECAST. IMPRESSIVE ISENTROPIC LIFT NOTED ACROSS THE
EAST AS WELL AS MOIST SPECIFIC HUMIDITY VALUES. LIFT APPEARS TO BE
STRONGEST OVER SOUTHEAST SOUTH DAKOTA...BUT MORE THAN SUFFICIENT
LIFT NOTED ACROSS THE ENTIRE EASTERN FORECAST AREA TO PRODUCE
WIDESPREAD PRECIP AND SIGNIFICANT SNOWFALL.

HELD ON TO THE WIND ADVISORY FOR THE FAR EAST THIS EVENING AS VERY
STRONG WINDS HAVE BEEN NOTED IN 8D3...ETH AND VVV ALL AFTERNOON.
SUSTAINED WINDS FROM 30 TO 40 MPH HAVE OCCURRED. NOT REALLY
MEETING CRITERIA ACROSS THE JAMES RIVER VALLEY...WATERTOWN AND
COUNTIES JUST TO THE WEST OF BROWN/SPINK. WILL THEREFORE CANCEL THE
ADVISORY A COUPLE HOURS EARLY AND HOLD ONTO IT ACROSS THE FAR
NORTHEAST THROUGH 6 PM CST.

.LONG TERM...MONDAY THROUGH FRIDAY
WITH WEAK SURFACE TROUGHING EXTENDING BACK INTO THE REGION ON
MONDAY ALONG WITH WEAK LOW LEVEL WINDS. EXPECT THE LOW CLOUDS TO
HANG AROUND...ESPECIALLY IN THE EASTERN CWA. ALSO...SOME
LINGERING LIGHT SNOW OR FLURRIES MAY STILL REMAIN ACROSS NORTHEAST
SD AND WEST CENTRAL MN INTO MONDAY. OTHERWISE...WEAK SURFACE HIGH
PRESSURE WILL BUILD OVER THE AREA MONDAY NIGHT AND TUESDAY. AGAIN
IT MAY BE DIFFICULT TO PUSH THE LOW CLOUDS OUT OF THE EAST. THE
MODELS CONTINUE TO AGREE THAT ANOTHER LARGE PACIFIC TROUGH WILL BE
MOVING ACROSS THE ROCKIES AND INTO THE CENTRAL PART OF THE US BY
THE MIDDLE OF THE WEEK. THIS MAY BRING ANOTHER ROUND OF
PRECIPITATION MAINLY SNOWFALL TO THE CWA FOR TUESDAY NIGHT INTO
THURSDAY. THE BEST CHANCES LOOK TO BE EAST IN THE AREA. IT SHOULD
THEN DRY OUT FOR LATER THURSDAY AND FRIDAY WITH SURFACE HIGH
PRESSURE AND COLDER AIR BUILDING IN.

&&
.AVIATION...
BIGGEST CONCERN FOR AVIATION COMMUNITY IS THE ONSET OF IFR
CIGS/VSBYS WITH FZRA/FZDZ/SN DEVELOPING ACROSS CWA. HAVE PUSHED
BACK ONSET OF PCPN MORE TOWARD 09Z AND LOWERED POPS TO CHC POPS.
HAVE ADDED SLEET MENTION TO EASTERN SITES/ROUTES THROUGH 12Z AS
WELL. STILL APPEARS THAT IFR CIGS/VSBYS IN SNOW LIKELY FOR
SATURDAY.
