AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ABERDEEN SD
836 PM CDT THU JUN 20 2013
.UPDATE...
NO MAJOR CHANGES THIS EVENING. EVENING RAOB DID SHOW SOME CAP
REMAINING. HOWEVER LLJ SHOULD EFFECTIVELY HELP WITH ELEVATED TSRA
DEVELOPMENT OVERNIGHT...ESPECIALLY IN THE EASTERN CWA. MAY
EVENTUALLY DEVELOP SOME SORT OF MCS OVER THE EAST THAT MOVES OFF
INTO MINNESOTA LATE.
&&
.PREVIOUS DISCUSSION...
.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT
EVERYTHING IS STILL SET FOR THE GOOD CHANCES OF SHOWERS AND
THUNDERSTORMS THROUGH THE SHORT TERM. A WEAK SURFACE LOW PRESSURE
AREA WAS LOCATED IN NORTH CENTRAL SD LATE THIS AFTERNOON WITH A
COOL FRONT EXTENDING SOUTHWARD ACROSS CENTRAL SOUTH DAKOTA. SOME
ELEVATED CONVECTION WAS DEVELOPING THIS AFTERNOON IN THE 700MB
RIDGE AXIS EAST RIVER THIS AFTERNOON. SATELLITE AND RADAR WERE
SHOWING THIS DEVELOPMENT LATE THIS AFTERNOON. VISIBLE SATELLITE
WAS ALSO SHOWING ABUNDANT CU CLOUDS ADVECTING NORTHWARD ACROSS THE
CWA EVIDENCE OF INCREASING MOISTURE. MUCH OF THE CAP HAS ERODED
ACROSS THE CWA WITH 2500-3000 J/KG MLCAPE ACROSS THE ENTIRE CWA.
THE LOW LEVEL FOCUS MECHANISM WAS OUT WEST AND THIS IS WHERE THE
INITIAL DEVELOPMENT IS EXPECTED. THERE WAS ALSO MOISTURE
CONVERGENCE EXTENDING ACROSS NORTH CENTRAL SD EAST TOWARDS THE
JAMES VALLEY LATE THIS AFTERNOON. ALSO...HAVE A WEAK SHORT WAVE TROUGH
MOVING OVER TONIGHT ALONG WITH A JET STREAK OFF TO THE NORTHWEST
AIDING IN THE UPPER LEVEL LIFT. EXPECT THE CONVECTION OUT WEST TO
EXPAND AS IT HEADS EAST THROUGH THE EVENING AND OVERNIGHT. SOME
SEVERE STORMS ARE EXPECTED. ALREADY HAVE A FLASH FLOOD WATCH
ISSUED FOR NORTHEAST SD AND WEST CENTRAL MN THROUGH TONIGHT AS
MORE HEAVY RAIN COULD CREATE FLOODING ISSUES FOR THIS REGION.
RAINFALL AMOUNTS OF 2 TO 5 INCHES OR MORE HAVE OCCURRED ACROSS
THIS REGION WITH SOME REPORTS OF FLOODING.
OTHERWISE...THE LARGE SCALE LOW PRESSURE TROUGH OUT WEST WILL
SEND OFF SEVERAL MORE SHORT WAVE TROUGHS WITH THE MAIN TROUGH
SWINGING INTO THE REGION SATURDAY AND SATURDAY NIGHT. THE COOL
FRONT OUT WEST THIS AFTERNOON WILL PUSH EAST ACROSS THE CWA
TONIGHT AND EARLY FRIDAY WITH WINDS BECOMING EAST AND NORTHEAST.
THIS BOUNDARY WILL MEANDER BACK AND FORTH ACROSS EASTERN SD
THROUGH SATURDAY NIGHT AS UPPER LEVEL ENERGY MOVES OVER THE
REGION. THERE WILL BE PLENTY OF DEEP LAYER SHEAR...MOISTURE AND
INSTABILITY THROUGH THE ENTIRE SHORT TERM FOR SEVERAL ROUNDS OF
THUNDERSTORMS ACROSS THE CWA. THE FRONTAL BOUNDARY LOCATION ALONG
WITH THE LOW LEVEL/850MB JET WILL BE THE MOST CONCERNING DURING THIS
TIME PERIOD. THE MODELS SHOW MORE OF A STRONGER WAVE MOVING OVER
THE REGION FRIDAY AND FRIDAY NIGHT WITH SHOWERS AND STORMS DEVELOPING.
SATURDAY AND SATURDAY NIGHT LOOK THE BEST FOR SEVERE WEATHER
CHANCES WITH THE MAIN UPPER LOW PRESSURE TROUGH MOVING INTO THE
REGION. HIGHS WILL BE MAINLY IN THE 80S WITH MOIST OVERNIGHT LOWS
IN THE 60S THROUGH THE SHORT TERM.
.LONG TERM...SUNDAY THROUGH THURSDAY
AN ACTIVE WEATHER PATTERN WILL CONTINUE THROUGH THE LONG TERM
PORTION OF THE FORECAST.
THE PERIOD BEGINS WITH SOUTHWEST FLOW ALOFT...WITH SHORT WAVE
ACTIVITY MOVING ACROSS THE REGION. THIS SHORT WAVE...ALONG WITH AN
ABUNDANCE OF LOW LEVEL MOISTURE WILL RESULT IN THUNDERSTORMS FOR
THE EASTERN CWA ON SUNDAY. ANOTHER SHORT WAVE EMBEDDED WITHIN THE
SOUTHWEST FLOW ALOFT WILL IMPACT THE REGION DURING THE AFTERNOON
HOURS ON MONDAY. SOME MODELS ARE SUGGESTING ADDITIONAL CHANCES FOR
SHOWERS AND THUNDERSTORMS TUESDAY THROUGH THURSDAY. BECAUSE OF
DIFFERENCES BETWEEN THE GFS/ECMWF...WILL USE ALLBLEND WHICH SHOW
MAINLY SCHC POPS. THAT SAID...BOTH MODELS ARE SHOWING AN UPPER
LEVEL RIDGE BUILDING INTO THE REGION JUST BEYOND THE PERIOD WITH
PERHAPS A LONGER TIME PERIOD OF DRIER CONDITIONS.
TEMPERATURES THROUGH THE PERIOD WILL BE AOA NORMAL FOR THIS TIME
OF YEAR...WITH HIGHS IN THE 80S AND LOWER 90S...WITH LOW IN THE 60S.
&&
.AVIATION...
00Z TAFS FOR THE KABR...KATY...KPIR AND KMBG TERMINALS
SHOWERS AND STORMS WILL BE POSSIBLE OVERNIGHT...ESPECIALLY AT
KABR/KATY. ACTIVITY SHOULD BE MORE ISOLATED IN NATURE OVER CENTRAL
SOUTH DAKOTA. OUTSIDE OF ANY THUNDERSTORMS GENERALLY VFR CONDITIONS
ARE EXPECTED EXCEPT TOWARD MORNING WHEN ANY CIGS OVER THE AREA MAY
LOWER INTO THE MVFR RANGE. VSBYS WILL BE GENERALLY VFR OUTSIDE ANY
CONVECTIVE ACTIVITY.
