AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ABERDEEN SD
1105 AM CDT TUE JUN 16 2009

.UPDATE...
NO MAJOR CHANGES MADE TO THE FORECAST THIS MORNING. AREA OF
SHOWERS AND THUNDERSTORM CURRENTLY OVER THE NORTH CENTRAL PART OF
THE CWA...WITH INDICATIONS OF MORE DEVELOPING TO THE WEST. SO
FAR...LIGHTNING AND HEAVY RAIN HAVE BEEN THE MAIN CONCERNS. STILL
EXPECT TO SEE MORE DEVELOPMENT THIS AFTERNOON...BUT SEVERE
CONCERNS ARE PRETTY MINIMAL. BIGGER CONCERN IS MORE RAIN OVER
AREAS THAT HAVE RECEIVED SIGNIFICANT RAINFALL THE LAST COUPLE OF
DAYS. WILL CONTINUE TO MONITOR FOR POSSIBLE FLOOD HEADLINES.

&&
.PREV DISCUSSION...
.SHORT TERM...TODAY THROUGH THURSDAY
PRECIPITATION CHANCES THROUGHOUT THE SHORT RANGE IS THE MAIN
FORECAST CHALLENGE.

A DRY LINE IS CURRENTLY MOVING ACROSS WESTERN SOUTH DAKOTA WITH
SOME PRE-FRONTAL SCATTERED SHOWERS AND THUNDERSTORM MOVING
NORTHEAST. DEW POINTS BEHIND THE DRY LINE ARE SHOWN TO BE IN THE
UPPER 40S TO THE LOWER 50S. AMPLE MOISTURE ACROSS MOST OF THE CWA
WILL RESULT IN ADDITIONAL THUNDERSTORM DEVELOP THROUGH AT LEAST
LATE MORNING. USED THE 4KM WRF WITH REGARDS TO THE PLACEMENT OF
THE BEST CHANCE FOR PRECIPITATION. LATER THIS AFTERNOON...BOUNDARY
LAYER DEW POINTS IN THE EASTERN HALF OF THE CWA INCREASE TO THE
MID 60S. HOWEVER THE BEST SHEAR AND CAPE VALUES ARE SOUTHEAST OF
THE CWA. IN THE SW CWA...MID LEVEL LAPSE RATES REACH TO PLUS 8C
LATER THIS EVENING...WITH DIURNALLY DRIVEN THUNDERSTORMS POSSIBLE.

LATE TONIGHT THROUGH WEDNESDAY MORNING LOOKS TO BE THE ONLY DRY
PERIOD...OR AT LEAST UNTIL THE NEXT MODEL RUN COMES IN. BEYOND
WEDNESDAY AFTERNOON...MODELS INDICATED SEVERAL HARD TO TIME SHORT
WAVES WILL MOVE ACROSS THE AREA. AT THIS TIME...THE EASTERN CWA
LOOKS TO BE THE BEST LOCATION TO SEE THUNDERSTORMS.

TEMPERATURES THROUGHOUT THE SHORT TERM WILL BE WITHIN A FEW
DEGREES OF CLIMO.

.LONG TERM...THURSDAY EVENING THROUGH SUNDAY EVENING
THE LONG TERM PERIOD STARTS OUT WITH AN UPPER LEVEL SHORT WAVE
TROUGH SWEEPING ACROSS THE REGION FRIDAY. CHANCES OF SHOWERS AND
THUNDERSTORMS EXIST WITH THIS FEATURE...ESPECIALLY FOR THE
NORTHEAST FA WHERE INSTABILITY IS THE GREATEST. THE PATTERN MAKES
A QUICK TRANSITION TO AN UPPER LEVEL RIDGE AND SURFACE HIGH
PRESSURE ON SATURDAY WHICH WILL RESULT IN BRIEF DRY PERIOD.
SATURDAY ALSO APPEARS TO BE THE WARMEST DAY OF THE LONG TERM
PERIOD WITH MODELS INDICATING 850 TEMPERATURES IN THE LOW 20S.
LATE SUNDAY INTO EARLY MONDAY ANOTHER SHORT WAVE AND SURFACE LOW
PRESSURE SYSTEM DEVELOPS AND BRINGS YET ANOTHER CHANCE OF
PRECIPITATION.

&&

.AVIATION...
MVFR CIGS COVER MUCH OF THE REGION THIS MORNING...WITH LINGERING
SHOWERS AND THUNDERSTORMS NEAR KABR. VSBYS MAY BE REDUCED TO 3-5
MI IN BR. ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS ARE POSSIBLE
THIS AFTERNOON AND EVENING WHICH COULD RESULT IN BRIEF MVFR/IFR
CONDITIONS.

...FUNNEL CLOUDS AND WEAK TORNADOES POSSIBLE THIS AFTERNOON...

THE COMBINATION OF ABUNDANT LOW LEVEL MOISTURE...AN UPPER LEVEL
DISTURBANCE...AND A WEAK FRONT ACROSS THE AREA WILL PRODUCE THE
POTENTIAL FOR FUNNEL CLOUDS AND WEAK TORNADOES THIS AFTERNOON AND
EVENING.

THESE TORNADOES ARE NOT ASSOCIATED WITH SUPERCELL THUNDERSTORMS
AND ARE GENERALLY MUCH WEAKER. HOWEVER...THEY CAN GENERATE WINDS IN
EXCESS OF 50 MPH...AND PRODUCE MINOR DAMAGE. IF YOU SPOT A TORNADO...TAKE
COVER IN A STURDY STRUCTURE UNTIL THE STORM PASSES.

LISTEN TO NOAA WEATHER RADIO...OR YOUR LOCAL MEDIA FOR THE LATEST
WEATHER RELATED UPDATES...INCLUDING POSSIBLE WARNINGS.
