AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
955 AM CDT SAT APR 23 2011

.DISCUSSION...
STRATUS WIDESPREAD ACROSS THE CWA AND WILL BE SLOW TO CLEAR FROM THE
NORTHWEST THIS AFTERNOON AND EVENING. IN FACT...WHERE SOME CLEARING
DOES OCCUR THIS AFTERNOON...SURFACE HEATING WILL CAUSE CUMULUS TO
REFORM AND THIS IS BECOMING APPARENT ON SATELLITE IMAGES. SO WILL
KEEP SKIES CLOUDY TO MOSTLY CLOUDY TODAY. WITH MORE CLOUD
COVER...WILL BE HARD TO PRODUCE ANY LIGHT RAIN AS LOW LEVELS WILL
REMAIN STABLE. TEMPERATURES WILL ALSO STRUGGLE TO CLIMB THROUGH THE
DAY AND HIGHS WILL ONCE AGAIN BE WELL BELOW NORMAL.

&&

.AVIATION...
MVFR CEILINGS WILL GRADUALLY BECOME VFR FROM THE WEST AFTER 20Z AND
ACROSS ALL OF THE CWA BY 03Z.

&&

.PREVIOUS DISCUSSION...
LOW WILL BE QUICKLY MOVING FURTHER EAST AWAY FROM AREA/ LIGHT
SHOWERS WHICH HAVE BEEN TRYING TO SWEEP SOUTHEAST INTO AREA ON BACK
SIDE OF LOW WILL HAVE ALMOST NO SUCCESS. WILL KEEP A SLIGHT CHANCE
LIGHT SHOWERS THIS MORNING FAR NORTH AND ISOLATED SPRINKLES DOWN TO
INTERSTATE 90...THIS MORE IN LOW CLOUD DECK ACCOMPANYING SYSTEM.
THESE LOW CLOUDS WILL BEGIN TO PULL EAST OUT OF AREA BY NOON AND
THIS PROCESS WILL ACCELERATE DURING THE AFTERNOON. THIS SHOULD MAKE
SKIES MOSTLY CLEAR BY EARLY EVENING OVER AREA. TEMPERATURES TODAY
WILL SHOW SOME WARMING IN RESPONSE TO MIXING ON BACK SIDE OF SYSTEM
AND INCREASING SUNSHINE LATER ON. WINDS WILL SLOWLY TAPER OFF FROM
CURRENT WINDY CONDITIONS.

CLEAR TO MOSTLY CLEAR SKIES AND LIGHT WINDS FOR MOST TO ALL OF
TONIGHT WILL PRODUCE IDEAL COOLING CONDITIONS. THE FOG THREAT IS
TEMPERED BY THE DRYING ASSOCIATED WITH THE MIXING AND THE SHORTER
NIGHTS THIS TIME OF YEAR. TEMPORIZED WITH PATCHY FOG LATE TONIGHT
INTO VERY EARLY SUNDAY MORNING EXCEPT FOR FAR SOUTHWEST CORNER WHERE
THERE MAY BE SOME INCREASE IN MIDDLE AND HIGH CLOUDS.

SUNDAY AND MONDAY WILL SEE THE VERY GRADUAL DEVELOPMENT OF WARM
ADVECTION LIGHT SHOWER THREAT WHICH WILL ONLY PICK UP AS THE NEXT
SYSTEM MOVES INTO AREA LATE MONDAY. IN FACT EXCEPT FOR A SLIGHT
CHANCE OF SHOWERS SOUTHWEST SUNDAY AFTERNOON...RAIN SHOULD HOLD OFF
THROUGH SUNDAY NIGHT. A CHILLY RAIN THREAT WILL THEN DEVELOP FOR
MONDAY AFTERNOON AND NIGHT ESPECIALLY OVER THE SOUTHEAST PART OF
AREA WHERE UPPER SUPPORT SEEMS TO BE TARGETING ITS APPROACH. UPPER
LOW HANGING AROUND WILL KEEP IT COOL WITH A MINIMAL LIGHT SHOWER
THREAT FOR TUESDAY NIGHT AND WEDNESDAY. WARMING TO NEAR OR SLIGHTLY
ABOVE NORMAL TEMPERATURES SHOULD TAKE PLACE THURSDAY AND FRIDAY
ALONG WITH EXPECTED DRY WEATHER. GFS AND ECMWF SHOULD SHOW A LITTLE
THREAT OF SHOWERS BY FRIDAY WITH WEAK SURFACE AND UPPER TROUGH...BUT
THREAT SEEMS TO LOW WITH UNCERTAIN TIMING TO INTRODUCE RIGHT NOW.
