AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ABERDEEN SD
307 AM CDT THU OCT 18 2007
.SHORT TERM...TODAY THROUGH FRIDAY NIGHT
FORECAST CHALLENGES INCLUDE WHEN TO END PRECIPITATION
TONIGHT...TEMPERATURES THURSDAY NIGHT THROUGH FRIDAY NIGHT...AND
WINDS TODAY THROUGH FRIDAY MORNING.
PRESENTLY...CYCLOGENESIS IS ONGOING OVER THE CENTRAL PLAINS WITH
PARENT UPPER LOW CENTER STILL SITTING IN SLIGHTLY
NEGATIVELY-TILTED UPPER LEVEL LONGWAVE TROF. THE UPPER LOW CENTER
IS CURRENTLY POSITIONED OVER NORTHEASTERN NEBRASKA. THE ASSOCIATED
SURFACE LOW PRESSURE CENTER IS SLOWLY DEEPENING AND LIFTING INTO
NORTHWESTERN IOWA...WHILE AN INVERTED SURFACE TROF IS DRAPED
ACROSS THE MISSOURI RIVER VALLEY OF THIS FORECAST AREA. PLENTY OF
LOW LEVEL CLOUDS...MOISTURE AND PRECIPITATION CONTINUE TO TAKE UP
RESIDENCE ACROSS THE FORECAST AREA. PRECIPITATION HAS BEEN FOCUSED
ALONG AND EAST OF THIS INVERTED SURFACE TROF SINCE WEDNESDAY
AFTERNOON. A NOTABLE PRECIPITATION FOOTPRINT IS SHOWING UP ON
RADAR FROM HYDE/HAND/BUFFALO COUNTIES NORTHWESTWARD INTO CORSON
AND CAMPBELL COUNTIES...WITH RAINFALL AMOUNTS OF MAINLY 0.5 INCH
TO 1.5 INCHES BASED OFF RADAR ESTIMATES. THE KABR 88D IS ALSO
SUGGESTING THAT A FEW AREAS HAVE RECEIVED ANYWHERE FROM 2 TO 5
INCHES OF RAINFALL IN THE PAST 12 HOURS. ADDITIONAL PVA-INDUCED
RAIN BANDS IN WARM-CONVEYOR BELT HAVE CONTINUED TO DEVELOP AND
WRAP NORTHWESTWARD INTO THIS FORECAST AREA OVERNIGHT. WHERE IT HAS
NOT BEEN RAINING IN EARNEST YET THIS MORNING...AREAS OF FOG AND
DRIZZLE HAVE BEEN OCCURRING. MORNING WEATHER GRIDS HAVE BEEN DRAWN
TO REFLECT THESE CONDITIONS...UNTIL WIND SPEEDS INCREASE DURING
THE DAY TODAY...WHICH SHOULD HELP TO DISSIPATE THE FOG AND DRIZZLE
CONDITIONS.
BOTH THE NAM AND GFS CONTINUE TO ADVERTISE A RATHER WRAPPED UP AND
STRONG LOW PRESSURE SYSTEM LIFTING NORTH INTO MINNESOTA
TODAY AND TONIGHT...WHICH WILL PRODUCE ADDITIONAL RAINFALL ACROSS
THE FORECAST AREA TODAY...TAPERING OFF FROM WEST TO EAST LATER
TONIGHT. AN ADDITIONAL 0.5 TO 1.5 INCHES OF RAINFALL IS POSSIBLE
TODAY AND TONIGHT WITH MUCH ABOVE NORMAL PWATS OF 0.75 INCH TO
1.25 INCHES HANGING OUT ACROSS THE REGION THROUGH THIS
EVENING...SO CONTINUED WITH THE SHOWERS OF MODERATE RAIN WORDING
IN THE GRIDS TODAY. MODEL WIND PROGS AND NUMERICAL GUIDANCE IN
BOTH THE NAM AND GFS SUGGEST RATHER STRONG WINDS OF 25 TO 35 MPH
WITH GUSTS TO 45 MPH WILL DEVELOP DURING THE DAY TODAY IN THE
TIGHTENING PRESSURE GRADIENT AS THIS SURFACE LOW DEEPENS FROM A
988MB LOW TO AROUND APPX 980MB THIS EVENING/OVERNIGHT. FOR THIS
REASON...HAVE HOISTED A WIND ADVISORY FOR THE FORECAST
AREA...STARTING AT 12Z ACROSS THE WESTERN HALF OF ZONES AND 18Z
ACROSS THE EASTERN HALF OF ZONES...VALID UNTIL 18Z ON FRIDAY.
OTHERWISE...HIGH PRESSURE /AT THE SURFACE AND ALOFT/ IS STILL
PROGGED TO BUILD INTO THIS FORECAST AREA FRIDAY AND FRIDAY
NIGHT...WHICH SHOULD WORK TO ERADICATE MOST /IF NOT ALL/ OF THE
LOW CLOUDS THAT HAVE BEEN AROUND FOR THE PAST 5 DAYS OR SO. WARMED
TEMPERATURES 3 TO 5 DEGREES ON THURSDAY NIGHT ACROSS THE WESTERN
HALF OF THE FORECAST AREA...FOLLOWING THE ARGUMENT THAT STRONG
MIXING WINDS WILL KEEP TEMPERATURES UP...EVEN IF CLOUDS ARE ON THE
DECREASE THURSDAY NIGHT. OTHERWISE...NO SIGNIFICANT CHANGES MADE
TO MAX/MIN TEMPERATURE OVER THE NEXT COUPLE OF DAYS.
.LONG TERM...12Z SATURDAY THROUGH WEDNESDAY.
BIGGEST CHALLENGE IN THE EXTENDED REVOLVES AROUND PCPN CHANCES FOR
THE WEEKEND.
THE LONG RANGE MODELS ARE BEGINNING TO CLOSE THE GAP A BIT IN
THEIR SOLNS. 12Z SATURDAY STARTS OFF WITH 5H RIDGE AXIS PUSHING
EAST OF THE CWA...WITH SOME MINOR WAVES BEGINNING TO MOVE INTO THE
REGION IN UPPER SW FLOW. THE EC IS A BIT QUICKER WITH COLD FRONT
PASSING THROUGH DURING THE DAY COMPARED TO THE GFS...MAYBE 6 HOURS
FAST...BUT BOTH AGREE ON FRONT BEING EAST OF THE CWA BY 00Z
SUNDAY. BOTH EC/GFS ALSO NOW AGREE ON SFC LOW FORMING ON TAIL OF
COLD FRONT...WITH BOTH MODELS SHOWING POST FROPA PCPN SETTING UP
OVER SECTIONS OF THE CWA ON SUNDAY. OF CONCERN IS THE FACT THAT
THE GFS SHOWS STRONG DOWNGLIDE ON THE 85H AND 7H THETA-E
SFCS...WHICH REALLY WOULDNT LEND ITSELF MUCH TO PCPN. ALSO THINK
THAT OUR 12 HOUR PCPN GRID FOR SUNDAY WILL NEED TO BE TRIMMED BACK
A BIT AS PWATS SHOW CONSIDERABLE DRY AIR INTRUSION DURING THE DAY
SUNDAY. FOR NOW...OPTED TO TWEAK CURRENT SUNDAY PCPN GRID AND WAIT
FOR FURTHER MODEL RUNS TO HELP SORT THINGS OUT.
TEMP WISE...GOOD WAA AHEAD OF COLD FRONT ON SATURDAY...ALONG WITH
DECENT MIXING..SHOULD ALLOW TEMPS TO WARM A BIT MORE THAN PREVIOUS
FORECAST HAD GOING. ALSO WITH STRONG CAA TAKING PLACE ON
SUNDAY...ENDED UP NUDGING DOWN TEMPS A DEGREE OR SO. ALSO NUDGED
DOWN SUNDAY NIGHT LOWS A BIT AS CLEARING SKIES...LIGHT WINDS AND
85H TEMPS FALLING TO OR JUST BELOW ZERO CELCIUS SHOULD HELP TEMPS
DROP.
