AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1027 AM CST MON JAN 31 2011

.DISCUSSION...
A FAIRLY LONG LIVED BAND OF MODERATE SNOW CONTINUES TO EXPAND ACROSS
SW MN INTO EC SD AND CREEP SOUTHEAST. WENT AHEAD AND EXPANDED THE
COVERAGE OF THE WARNING TO INCLUDE AREAS NORTH OF I90 IN SW MN WEST
THROUGH BROOKINGS AND MADISON. LOOKS LIKE AN ADDITIONAL 2 TO 4
INCHES IS POSSIBLE THROUGH THE AFTERNOON WITH 5 TO 6 ALREADY
REPORTED. WIND SHOULD NOT BE A MAJOR FACTOR DURING THE HEAVIER
SNOW...BUT WILL BECOME ONE LATER TONIGHT INTO TUESDAY. BETTER
SUPPORT FOR THE SNOW BEGINS TO FALL APART THIS AFTERNOON AS THE
SOUTHERN STREAM WAVE OVER THE FOUR CORNERS REGION OF THE U.S. MOVES
ONTO THE PLAINS. THIS SHOULD COLLAPSE THE MID LEVEL FRONT FARTHER
SOUTH AND TAKE THE BETTER SNOWFALL TO THE SOUTH. MAY NEED TO LOWER
SNOWFALL AMOUNTS TONIGHT INTO TUESDAY IF THE TRENDS ON BETTER
FORCING TO THE SOUTH CONTINUES. /08

&&

.PREV DISCUSSION...
BAND OF LIGHT TO MODERATE SNOW MOVING ENE ACROSS THE NORTHERN HALF
OF THE CWA THIS MORNING WITH THE BEST ENHANCEMENT SEEN NORTH OF I90
AND EAST OF I29 WHERE THE STRONGEST ISENTROPIC LIFT IS OCCURRING. TO
THE SOUTH...SNOW QUICKLY TAPERS TO FLURRIES.  SNOW RATIOS REMAIN
QUITE HIGH AND HAS REACHED 20 TO 1 ACROSS THE NORTH. ANOTHER PUSH OF
LIGHT SNOW IS EXPECTED TO START WORKING INTO THE SOUTHERN BORDER
WITHIN THE NEXT HOUR OR TWO ENHANCED BY A SECONDARY INVERTED TROUGH
TRACKING TOWARDS OUR SOUTHWEST BORDER.  THE TROUGH HANGS UP ACROSS
THE EASTERN HALF OF THE CWA BY THIS AFTERNOON AND BEGINS TO FOCUS
THE BEST ENHANCED PRECIPITATION ACROSS THE SOUTHERN AND EASTERN
SECTORS OF THE CWA THIS AFTERNOON AND EVENING.  SNOW WILL WEAKEN
AFTER MIDNIGHT THEN GRADUAL TAPER OFF FROM NORTHWEST TO SOUTHEAST
TUESDAY THROUGH TUESDAY EVENING. DEVELOPING DEEP CYCLOGENESIS IN THE
CENTRAL PLAINS PASSES WELL SOUTH AND EAST OF THE CWA...HOWEVER SOME
RESIDUAL LIGHT SNOW CLIPPING THE EXTREME SOUTHEAST CORNER TUESDAY
NIGHT.

CURRENT WINTER WEATHER ADVISORIES AND THE STORM WARNING REMAIN ON
TRACK SO WILL KEEP THEM GOING FOR NOW. HIGHEST TOTALS ARE EXPECTED
ACROSS OUR NORTHERN BORDER WITH 8 TO 10 INCHES AND 5 TO 8 EXPECTED
ELSEWHERE. ACCUMULATING SNOWFALL MAY END EARLY ON TUESDAY ACROSS THE
NORTHERN HALF OF THE CWA BUT WILL KEEP CURRENT 00Z WED EXPIRATION
FOR SIMPLICITY.

STRONG CAA FILTERS INTO THE AREA FROM THE NORTHWEST...ALONG WITH
GUSTY WINDS TODAY INTO TUESDAY NIGHT.  CLOUD COVER WILL DELAY THE
STRONGEST PUSH UNTIL TUESDAY NIGHT PARTICULAR WHEN RAPID CLEARING
WILL DRIVE THE LOWS INTO THE TEENS AND LOW 20S BELOW ZERO.
CONTINUED GUSTY WINDS COMBINED WITH THE COLD TEMPS WILL RESULT IN
WIND CHILLS OF 30 TO 40 BELOW FOR MUCH OF THE AREA. GIVEN THE
CURRENT HEADLINES...WILL DELAY ANY PRODUCT ISSUANCE FOR TUESDAY
NIGHT. IN ADDITION...THE WINDS COULD BRING SOME SIGNIFICANT BLOWING
AND DRIFTING TONIGHT THROUGH TUESDAY...AND CONTINUING ACROSS THE
SOUTHEAST HALF INTO EARLY WEDNESDAY.

.AVIATION...
WDSPRD MVFR TO IFR CIGS AND VSBYS DUE TO SNOW WL PREVAIL N OF I90
THRU 12Z MON...WITH MVFR CIGS AND PATCHY LIGHT SNOW TO THE S. IFR
CIGS SHUD BECOME WDSPRD ACRS ALL OF THE REGION AFTER 12Z MON ALONG
WITH WDSPRD LIGHT SNOW REDUCING VSBYS AOB 3SM. NORTH WINDS WILL
