AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ABERDEEN SD
423 AM CDT MON MAR 23 2009
.SHORT TERM...THROUGH WEDNESDAY
SECOND BATCH OF PRECIPITATION IS ON ITS WAY...HOWEVER LOW LEVEL JET
ACTIVITY PERSISTS IN THE EAST. HAVE MADE ONLY MINOR CHANGES TO
FORECAST...WITH HIGHER PRIORITY GOING TO WINTER WEATHER ON THE
BACK SIDE OF THE SYSTEM.
HPC 12 INCH SNOWFALL AMOUNTS FOR EXTREME WESTERN DEWEY AND CORSON
JIVE WITH THE SREFS 80 PROBABILITY OF GREATER THAN 8 INCHES FOR
PERKINS COUNTY. HARDEST PART TO FIGURE OUT WILL BE HOW RAPID SNOW
ACCUMULATIONS DROP OFF TO THE EAST. WIND STRENGTH WILL BE MAIN
DETERMINING FACTOR IN WARNING/ADVISORY CHOICES. WHILE PRESSURE
RISES ON BACK SIDE OF SYSTEM ARE NOT PARTICULARLY HIGH...6 MB/6
HRS...STRONG COLD ADVECTION AND UNIDIRECTIONAL SHEAR SUPPORTS
FAIR MIXING OF H85 +50KT WINDS. FLOODING CONTINUES TO REMAIN AN
ISSUE FOR MUCH OF THE CWA...AND LITTLE IMPROVEMENT CAN BE
ENVISIONED DURING THE FORECAST PERIOD.
SYSTEM PULLS OUT TO THE NORTHEAST LATE TUESDAY...SUPPORTING
IMPROVING CONDITIONS.
.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY
THE STORMY PATTERN OF RECENT DAYS WILL CONTINUE INTO THE EXTENDED.
EARLY IN THE PERIOD THE GFS MAINTAINS THAT SOME ENERGY IN FLAT
FLOW WILL BRING LIGHT SNOW TO THE REGION. THE EC ON THE OTHER HAND
KEEPS MOST OF THAT PCPN TO THE SOUTH. MEANWHILE...ANOTHER STRONG
LOOKING JET DIVES INTO THE SOUTHWEST CONUS...AND THEN EJECTS A
STRONG STORM INTO THE MIDDLE CONUS NEXT WEEKEND. THE TRACK OF THIS
SYSTEM SHOULD BE MAINLY SOUTH AND EAST OF THE REGION...HOWEVER THE
MOST RECENT MODEL RUNS ARE TRENDING THAT SYSTEM TO THE NORTH. SO
THIS BARES SOME WATCHING. FOR THE MOST PART TEMPERATURES WILL BE
BELOW NORMAL AS THE REGION REMAINS UNDER THE INFLUENCE OF CANADIAN
HIGH PRESSURE.
&&
.AVIATION...
THERE WILL BE QUITE A MIX OF WEATHER ACROSS THE REGION TODAY.
SHOWERS AND STORMS ARE LIKELY EARLY THIS MORNING OVER THE
EAST...MAINLY NEAR KATY...AND THEN SCATTERED SHOWERS AND STORMS
ARE EXPECTED AGAIN THIS AFTERNOON AND EVENING AND COULD AFFECT ALL
TERMINALS. ALSO THIS MORNING PATCHY FOG WILL AFFECT KMBG/KPIR BUT
MOST OF THAT SHOULD DISSIPATE BY MID MORNING. A MIX OF MVFR AND
VFR CIGS CAN BE EXPECTED THROUGH TNT.
