AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
845 PM CDT WED JUN 22 2011

.DISCUSSION...
UPPER LOW CONTINUES TO PUSH ITS WAY EASTWARD THIS EVENING...ALLOWING
FOR CLEARING SKIES IN THE WEST AND DECREASING SHOWER ACTIVITY IN THE
EAST. MAIN SHOWER ACTIVITY AT THIS TIME IS OVER SW MN...BUT EVEN
THAT IS SCATTERED IN NATURE AND LIGHT. RADAR SHOWING A FEW RETURNS
ACROSS SE SD AT THIS TIME...BUT PROBABLY NOT MUCH MORE THAN A FEW
SPRINKLES. NO CHANGES TO THE GOING FORECAST AND TEMPERATURES...CLOUD
COVER...AND SHOWER ACTIVITY RIGHT ON TRACK. BY SUNRISE SHOULD HAVE
CLEAR SKIES FROM AROUND I29 AND WEST...WITH CLOUDS HOLDING ON TO THE
EAST...AND POSSIBLY A FEW SPRINKLES. 97

&&

.AVIATION...
WEST OF THE JAMES RIVER VALLEY...CONDITIONS WILL LIKELY BE VFR
TONIGHT AND THURSDAY. HOWEVER ALONG AND E OF THE JAMES...UPPER END
IFR TO MVFR WILL LIKELY PERSIST TONIGHT AND INTO EARLY THURSDAY.
THERE ARE INDICATIONS FROM THE LATEST MODELS THAT HIGH LEVELS OF
RELATIVE HUMIDITY IN THE UPPER IFR TO LOWER MVFR RANGE WILL WORK
BACK SOUTHWARD OVERNIGHT INTO THE JAMES VALLEY AND I 29 CORRIDOR
FROM EASTERN ND. THEN IT IS QUITE LIKELY THAT THIS STRATUS WILL
SCOUR OUT AROUND 15Z THURSDAY...BUT THEN REDEVELOP AS A BROKEN
STRATOCU DECK IN THE AFTERNOON PROBABLY JUST INSIDE THE VFR RANGE.
EAST OF I 29 IN SW MN AND MOST OF NW IA...CONDITIONS WILL LIKELY
STAY IFR TO MVFR FOR A LONGER PERIOD OF TIME...WITH A RISK OF
SHOWERS TONIGHT. IN FACT EAST OF I 29 MAY BATTLE MVFR THROUGH
THURSDAY.

&&

.DISCUSSION...
THE DEEP UPPER LOW SITTING OVER SOUTHEAST MINNESOTA WILL CONTINUE TO
SHIFT EASTWARD THIS EVENING AND TONIGHT...BRINGING AN EVENTUAL END
TO SPOTTY SHOWERS ACROSS THE FORECAST AREA. WINDS WILL ALSO BEGIN TO
DIE DOWN THIS EVENING AS THE PRESSURE GRADIENT LESSENS...WHICH WILL
COMBINE WITH SLOWLY CLEARING SKIES...AND ALLOW TEMPERATURES TO FALL
LOWER THAN PREVIOUS NIGHTS. RAINFALL ACCUMULATIONS THROUGH TONIGHT
SHOULD BE VERY LIGHT DESPITE INCREASING LOW LEVEL MOISTURE AFTER
06Z...AS THE BEST FORCING FOR MODERATE PRECIPITATION WILL HAVE MOVED
EAST OF THE REGION. /LAFLIN

THURSDAY WILL STILL SEE RESIDUAL COOL LOW LEVEL AIR WHICH WILL KEEP
TEMPERATURES A BIT AT BAY THROUGH THE DAY. HOWEVER...WITH A
DECREASING NORTHWEST WIND AND DECREASING CLOUD COVER...A MUCH NICER
DAY IS IN STORE. LOOKING AT HIGHS ABOUT 5 OR 6 DEGREES WARMER THAN
TODAY...RANGING FROM THE MID 60S IN SW MN TO THE MID 70S IN SC SD.
LIKELY A BIT BREEZY IN THE MORNING...BUT GRADUALLY TAPERING OFF
THROUGH THE DAY AS THE GRADIENT SLACKENS.

THURSDAY NIGHT WILL SEE A RIDGE OF HIGH PRESSURE BUILD SOUTH INTO
HE AREA AND WITH MOSTLY CLEAR SKIES EXPECT DECENT RADIATIONAL LOWS
AND SOME POTENTIAL FOR FOG AS WELL. NOT TOO MUCH CHANGE FROM
PREVIOUS FORECAST WITH UPPER 40S TO LOWER 50S FAIRLY COMMON.

RETURN FLOW WILL SET UP IN THE WEST ON FRIDAY WITH INSTABILITY
BUILDING UP THE WESTERN HIGH PLAINS. WITH EAST TO SOUTHEAST FLOW IN
THE LOW LEVELS...EXPECT THE BETTER CHANCES TO REMAIN WEST OF THE
CWA. HOWEVER...SOME LATE MORNING TO MID AFTERNOON 800MB TO 700MB
FORCING COULD BRING THE THREAT FOR A FEW ACCAS SHOWERS AND
THUNDERSTORMS TO FAR WESTERN AND NORTHWESTERN PARTS OF THE CWA. NOT
EXPECTING ANY OF THIS ACTIVITY TO BE SEVERE OR BRING THE THREAT
FOR HEAVY RAINFALL.

FRIDAY NIGHT INTO SATURDAY WILL BE SIMILAR WITH A THREAT FOR
THUNDERSTORMS IN MAINLY THE WESTERN AND SOUTHERN PARTS OF THE CWA.
VERY GRADUALLY WARMING DURING THIS TIME BUT STILL LOOKING AT BELOW
NORMAL TEMPERATURES. HIGHS MAINLY IN THE 70S WITH LOWS FROM THE
UPPER 50S TO LOWER 60S.

IN THE LATTER PERIODS(SUN/WED)...THE PERIOD BEGINS WITH SOME THREAT
FOR SHOWERS AND THUNDERSTORMS BUT BY TUESDAY AFTERNOON INTO
WEDNESDAY THE MAIN TROUGH TO THE NORTH PUSHES EAST AND RIDGING ALOFT
BEGINS TO DEVELOP FROM THE WEST. A FAVORABLE UPPER LEVEL FLOW
PATTERN SETS UP LATE SUNDAY WITH FAIRLY FAST WEST SOUTHWEST AND
SHOULD CONTINUE THROUGH ABOUT TUESDAY WHEN EACH MODEL EJECTS THE
MAIN TROUGH. WILL HAVE THE BEST CHANCE FOR THUNDERSTORMS IN SUNDAY
NIGHT INTO MONDAY...THEN DRY THINGS OUT TUESDAY INTO WEDNESDAY.
OVERALL...TEMPERATURES SHOULD BE PRETTY CLOSE TO NORMAL...OR A
LITTLE ABOVE...ESPECIALLY INTO MID WEEK. WILL SEE SOME INCREASE IN
HUMIDITY AS WELL DURING THIS TIME. /08
