AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ABERDEEN SD
324 AM CDT MON SEP 1 2008

.SHORT TERM...TODAY THROUGH WEDNESDAY
COLD FRONT IS LOCATED ACROSS THE CENTRAL DAKOTAS EARLY THIS
MORNING AND WITHIN THE ABR CWA ITS ABOUT RIGHT ON TOP OF MBG TO
JUST WEST OF PIR. BREEZY SOUTH WINDS CONTINUE ACROSS THE EASTERN
CWA AHEAD OF THIS FRONT WITH MANY LOCATIONS STILL IN THE MID 70S
YET AT 3 AM CDT. SHARP TEMP FALLS HAVE BEEN NOTED BEHIND FRONT
WITH LOWER 60S ACROSS THE FAR NORTHWESTERN CWA. THIS WILL MAKE
FOR A VERY TRICKY HIGH TEMP FORECAST ALONG THE FRONT AS THERE WILL
BE A RATHER LARGE TEMP GRADIENT ACROSS CENTRAL SOUTH DAKOTA TODAY.
AREAS WELL EAST OF THE FRONT NOT SO TOUGH AND SHOULD MANAGE THE
MID TO UPPER 80S...POSSIBLY 90 IN SOME LOCATIONS. CONCERNING THE
FRONT ITSELF...LOOKS LIKE IT WILL MOVE LITTLE DURING THE MORNING
HOURS AND IN FACT...MAY EVEN MOVE BACK TO THE WEST A BIT AS A WAVE
OF ENERGY RIDES NORTHWARD ALONG THE FRONT. RUC/NAM SUGGESTING
FRONT MOVING BACK TO THE WEST SEVERAL MILES AS THE WAVE COMES
THROUGH...THEN ONCE THE WAVE LIFTS INTO NORTH DAKOTA THIS
AFTERNOON IT BEGINS TO MOVE EASTWARD AGAIN. MODELS SHOWING FRONT
APPROACHING JAMES VALLEY AROUND 00Z THIS EVENING. NOT EXPECTING
MUCH IN THE WAY OF PRECIP PRIOR TO 18Z WITH BEST CHANCES ACROSS
THE FAR NORTHWESTERN CWA. LATE THIS AFTERNOON EXPECTING MORE
DEVELOPMENT ALONG AND BEHIND THE FRONT AND INCREASED POPS A BIT
ALONG AND WEST OF THE JAMES VALLEY. SVR POTENTIAL NOT LOOKING TOO
GREAT BUT CANNOT RULE OUT A FEW STRONG TO LOCALLY SVR STORMS. SPC
HAS INCLUDED THIS AREA IN DAY ONE SLIGHT RISK FOR MARGINALLY SVR
HAIL OR WIND GUSTS. WIND GUSTS LOOK TO BE THE BETTER BET AS
FREEZING LEVELS ARE RATHER HIGH AND LAPSE RATES REALLY ARE NOT
THAT IMPRESSIVE. POTENTIAL FOR HEAVY RAIN IS THERE...ALTHOUGH NOT
OVERLY EXCITED ABOUT IT. OVERNIGHT LOOKS TO BE WHEN LOCALLY HEAVY
RAIN COULD BE POSSIBLE AS NEXT WAVE RIDES ALONG FRONT. MODELS IN
GOOD AGREEMENT WITH FAIRLY WIDESPREAD PRECIP OVERNIGHT ACROSS MUCH
OF THE CWA. HAVE INCREASED POPS A BIT OVERNIGHT ALSO. INSTABILITY
REALLY DROPS OFF AFTER 06Z TONIGHT SO TRENDED WX GRIDS TO JUST
RAIN SHOWERS AFTER THEN. PRECIP LOOKS TO MOVE OUT RATHER QUICKLY
EARLY TUESDAY MORNING AND LEFT SMALL CHANCE POPS ACROSS THE EAST
DURING THE MORNING HOURS. WENT DRY DURING THE AFTERNOON AS PRECIP
LOOKS TO BE EAST OF THE AREA BY THEN. HIGH PRESSURE AND COOL TEMPS
FOLLOW FRONT FOR TUESDAY AND STILL LOOKING AT HIGHS IN THE 60S
WITH A WEST TO NORTHWEST BREEZE. LIGHT WINDS AND COOL TEMPS
EXPECTED TUESDAY NIGHT AND WEDNESDAY AS HIGH PRESSURE REMAINS OVER
THE AREA. WOULD NOT BE SURPRISED IF A FEW LOCATION SNUCK INTO THE
UPPER 30S BY WEDNESDAY MORNING.

CONCERNING WINDS TODAY...DEBATED ON A WIND ADVISORY FOR THE FAR
EASTERN COUNTIES EAST OF I-29. DOES NOT LOOK QUITE AS DEFINITE AS
YESTERDAY WAS FOR AREAS FARTHER WEST...BUT MARGINAL NONETHELESS.
DECIDED TO HOLD OFF RIGHT NOW AND LET MORNING SHIFT DO SOME OB
WATCHING AND ISSUE IF NEED BE.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY
THE UPPER LEVEL PATTERN THROUGHOUT THE EXTENDED PERIOD WILL
FEATURE A BROAD TROUGH ACROSS THE NORTHERN PART OF THE
COUNTRY...WITH A SERIES OF SHORTWAVES TRACKING ACROSS THE
NORTHERN PLAINS. THESE WAVES LOOK TO AFFECT THE CWA LATE WEDNESDAY
NIGHT...THURSDAY AFTERNOON...FRIDAY AFTERNOON...AND SATURDAY
NIGHT. AT THE SURFACE...HIGH PRESSURE WILL EXTEND FROM THE EASTERN
PLAINS TO MICHIGAN WEDNESDAY NIGHT...WITH A WEAK TROUGH OVER THE
LEE OF THE ROCKIES. THIS TROUGH SLOWLY PUSHES ACROSS THE NORTHERN
PLAINS THURSDAY AND THURSDAY NIGHT. NOT MUCH IN THE WAY OF
INSTABILITY AROUND AND MOISTURE BEING CUT OFF BY WHAT WILL BE THE
REMNANTS OF HURRICANE GUSTAV...BUT WITH UPPER WAVE TRACKING
THROUGH...FEEL AT LEAST A SMALL POP FOR RAIN SHOWERS IS WARRANTED.
THE SURFACE TROUGH SLIDES EAST OF THE REGION ON FRIDAY WITH HIGH
PRESSURE BACK OVER THE NORTHERN PLAINS FRIDAY NIGHT. ANOTHER LEE
TROUGH DEVELOPS ON SATURDAY AND SLIDES TO THE CENTRAL DAKOTAS
SATURDAY NIGHT. THIS TROUGH EXITS THE REGION ON SUNDAY WITH HIGH
PRESSURE BEGINNING TO NOSE DOWN FROM THE NORTHWEST.

TEMPERATURES WILL REMAIN BELOW NORMAL THROUGH THE PERIOD WITH
LITTLE IN THE WAY OF SIGNIFICANT WAA EXPECTED. H85 TEMPS WILL BE IN
THE +6 TO +14 DEGREE RANGE...RESULTING IN NIGHTTIME TEMPS IN THE
40S AND DAYTIME HIGHS IN THE UPPER 60S TO MID 70S.

.AVIATION...
VFR CONDITIONS WILL PREVAIL ACROSS THE AREA THIS MORNING WITH JUST
SOME SCT HIGH CLOUDS AOA 20K FEET ACROSS THE EASTERN CWA...AND
BKN-OVC HIGH CLOUDS AOA 10K FEET ACROSS THE WEST. GUSTY SOUTH
WINDS OF 20 TO 35 MPH WILL OCCUR AT THE KATY AND KABY TAF SITES
THROUGH MID TO LATE AFTERNOON. A FRONTAL BOUNDARY WILL TRACK
ACROSS THE CWA THIS AFTERNOON AND EVENING...REACHING KABR AND
KPIR AROUND 23Z...AND KATY AROUND 04Z. WINDS WILL SHIFT AROUND TO
THE NORTHWEST...AND SHOWERS AND THUNDERSTORM ARE EXPECTED ALONG
AND BEHIND THE FRONT. CIGS AND VSBYS MAY FALL INTO THE MVFR
CATEGORY WITH THE STRONGER STORMS.
