AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ABERDEEN SD
1019 AM CST WED JAN 14 2009

.UPDATE...
THE ONLY DIRECTION TEMPERATURES WILL MOVE TODAY IS DOWN...SO HAVE
DROPPED MAX T TO THE AM OBS. WINDS REMAIN IN THE 10 TO 15KT
CATEGORY SO HAVE EXTENDED WIND CHILL WARNING THROUGH THE EARLY
AFTERNOON HOURS.  NO OTHER CHANGES AT THIS TIME.

&&
.PREV DISCUSSION...
.SHORT TERM...TODAY THROUGH FRIDAY
YESTERDAYS LOW PRESSURE SYSTEM WHICH BROUGHT SNOW HAS MOVED SOUTH
INTO IOWA AS ATTENTION TURNS TO THE ARCTIC HIGH PRESSURE SYSTEM
MOVING SOUTH INTO THE REGION FROM CANADA. STILL AN ABUNDANCE OF
CLOUDS ACROSS THE REGION WITH RADARS/OBS CONFIRMING FLURRIES
ACROSS A GOOD PORTION OF THE AREA. WILL KEEP MENTION OF FLURRIES
IN THE FORECAST THROUGH 15Z. THE ENTIRE CWA EXCEPT FOR THE FAR
SOUTHWEST COUNTIES ARE EXPERIENCING WIND CHILL ADVISORY CRITERIA
AT THIS TIME...WITH READINGS FROM 25 TO 35 BELOW ZERO. WILL KEEP
THE WIND CHILL HEADLINES GOING THROUGH THIS EVENING. AFTER
02Z...WINDS ARE EXPECTED TO DROP OFF TO LIGHT/VARIABLE AS THE HIGH
BEGINS TO CENTER ITSELF OVER THE AREA. WILL HAVE TO KEEP A CLOSE
EYE ON WIND SPEEDS AND TEMPS THIS MORNING AS A FEW LOCATIONS MAY
SNEAK INTO WIND CHILL WARNING CRITERIA WITH READINGS FROM 35 TO AS
MUCH AS 40 BELOW ZERO. IN FACT...A FEW OBS ARE ALREADY SHOWING
THIS ACROSS NORTHEASTERN SD BUT WILL STICK WITH THE ADVISORY FOR
NOW AS THIS IS OCCURRING IN ISOLATED LOCATIONS AND WIND SPEEDS
SHOULD COME DOWN ABOUT 5 MPH OVER THE NEXT FEW HOURS.

HIGH PRESSURE WILL CONTINUE TO MOVE SOUTH TODAY AND BRING CLEARING
SKIES FROM NORTH TO SOUTH. AFTER DARK WINDS WILL BECOME LIGHT AS
THE HIGH MOVES OVERHEAD. WIDESPREAD 20S BELOW ZERO EXPECTED
TONIGHT AND WOULD NOT BE SURPRISED IF FAVORED COLD SPOTS REACH 30
BELOW ZERO...ABERDEEN BEING ONE OF THEM. HIGH PRESSURE WILL REMAIN
IN THE AREA THROUGH THURSDAY EVENING...KEEPING THE ARCTIC AIR IN
PLACE. HIGHS ON THURSDAY WILL ONCE AGAIN BE BELOW ZERO ACROSS THE
EASTERN CWA. IN FACT...MUCH OF THE EASTERN CWA WILL NOT SEE TEMPS
ABOVE ZERO UNTIL SOMETIME FRIDAY MORNING.

AS THE HIGH MOVES EAST THURSDAY NIGHT...GOOD SHOT OF WAA SPREADS
ACROSS THE CWA AND SHOULD SEE STEADY OR SLOWING RISING TEMPS
OVERNIGHT AND INTO FRIDAY MORNING. DID JUST THIS IN THE HOURLY
TEMP GRIDS. MAV GUIDANCE ALSO SHOWING WARMING TEMPS THURSDAY
NIGHT. FRIDAY HIGHS RATHER TOUGH AS WARMER 850MB TEMPS SPREAD OVER
THE AREA...BUT WILL BE FIGHTING A DEEP SNOW PACK ACROSS MUCH OF
THE REGION. IT DOES APPEAR A RECOVERY IS IN PLACE AS TEMPS SHOULD
REACH THE 20S AND 30S WEST OF THE JAMES RIVER...WITH COOLER TEENS
ACROSS THE FAR EASTERN CWA. THIS NEEDS TO BE WATCHED THOUGH AS
GUIDANCE SHOWING EVEN THE FAR EAST WARMING INTO THE 20S BY FRIDAY.

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY
TEMPERATURES ARE EXPECTED TO BE THE MAIN CHALLENGE IN THE EXTENDED
FORECAST. MEANWHILE...THE LONG WAVE PATTERN WILL HOLD ONTO ITS
CURRENT POSITIVE PNA LOOK...BUT SHOULD SHIFT A BIT EAST AND ALSO
GO THROUGH SOME WEAKENING TOWARD THE END OF THE PERIOD AS ENERGY
COMES OFF THE PACIFIC AND BASHES THE WESTERN CONUS RIDGE DOWN.

A CLIPPER IS SILL EXPECTED TO DIVE INTO THE BACKSIDE OF THE
EASTERN CONUS TROF ON FRIDAY NIGHT AND SATURDAY AND THIS SYSTEM
COULD STILL BRING SOME LIGHT SNOW TO THE NORTHEASTERN CWA...BUT
CHANCES FOR MEASURABLE STILL DONT LOOK ALL THAT PROMISING...SO
SLIGHT CHANCE POPS WILL CONTINUE. THE REMAINDER OF THE EXTENDED
SHOULD FEATURE LITTLE OR NO PCPN.

TEMPERATURE-WISE...AS UPPER RIDGE BUILDS EAST WE SHOULD SEE A
GRADUAL WARM UP...BUT FIGURING OUT JUST HOW WARM IS THE BIG
QUESTION. H85 TEMPS RECOVER NICELY...ESPECIALLY EARLY NEXT WEEK AS
DOWN SLOPING FLOW DEVELOPS ACROSS THE WESTERN HIGH PLAINS/EASTERN
SLOPES OF THE ROCKIES. STEPPING BACKWARD A BIT...FOR THIS UPCOMING
WEEKEND IT APPEARS THAT SUNDAY WILL BE THE BETTER MIXING DAY AND
TEMPERATURES COULD PROVE RELATIVELY MILD...ESPECIALLY OVER THE
SOUTHWEST CWA WHERE SNOWFIELD IS THINNING OR NONEXISTENT.

VFR CONDITIONS CAN BE EXPECTED THROUGH THE NEXT 24 HOURS.
