AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
430 AM CDT SAT MAR 22 2008

.DISCUSSION...
WILL SEE SOME LIGHT SHOWERS SLIDE SOUTHEAST ACROSS THE AREA AS A
COUPLE OF WEAK WAVES DROP SOUTHEAST ACROSS MINNESOTA TODAY INTO THIS
EVENING. DEEPEST MOISTURE MOVES ACROSS THE NORTHEAST 1/3 OF THE
FA...AND HAVE BUMPED POPS INTO LOW CHANCE RANGE FROM KBKX INTO MUCH
OF SOUTHWEST MINNEOTA...WITH MORE ISOLATED/TRACE ACTIVITY EXPECTED
FARTHER WEST AND SOUTH TOWARD KHON/KFSD/KSPW. NOT MUCH RECOVERY FROM
CURRENT TEMPS TODAY...ESP IN THE NORTHEAST WITH WIDESPREAD STRATUS
AND WEAK COLD ADVECTION EXPECTED THROUGH THE DAY. THOUGH EVEN THE
MISSOURI VALLEY WILL STRUGGLE TO TOP 40.

UPPER TROUGH BEGINS TO PULL EAST AND LOSE ITS INFLUENCE ON OUR AREA
SUNDAY...WITH MORE ZONAL FLOW PATTERN SETTING UP THROUGH THE FIRST
HALF OF THE WEEK. PROGRESSIVE NORTHERN STREAM THROUGH THIS PERIOD
WITH SOME QUICK MOVING WAVES SLIDING EAST NEAR THE INTERNATIONAL
BORDER. EXPECT LITTLE EFFECT FROM THESE WAVES ACROSS OUR AREA AS FAR
AS PRECIPITATION CHANCES GO...WITH BEST...ALBEIT STILL MEAGER CHANCE
IN THE FAR NORTHEAST MONDAY NIGHT WHEN MODELS SEEM TO AGREE ON WAVE
TRACKING A LITTLE FARTHER SOUTH INTO MINNESOTA. ONE MORE COOLISH DAY
FOR EASTER BEFORE WARMUP BEGINS FOR THE FIRST HALF OF THE WEEK.
WARMEST DAY LOOKS TO BE MONDAY...WITH GOOD MIXING POTENTIAL IN
SOUTHERLY FLOW AHEAD OF THE WAVE/WEAK COOL FRONT. ANOTHER STRONG
MIXING DAY TUESDAY WITH DEEP WEST/NORTHWEST FLOW ACROSS THE AREA.
LOW LEVEL TEMPS ABOUT 3-5C COOLER THAN MONDAY THOUGH...SO NOT QUITE
AS WARM AS MONDAY...BUT STILL NEAR TO SLIGHTLY ABOVE NORMAL. GFS
SOUNDINGS ACTUALLY POINTING TO POTENTIAL FOR ADVISORY CRITERIA WINDS
AS WE MIX OUT ON TUESDAY. 84HR FORECAST FROM LATESTE 06Z NAM SHOWING
SIMILAR IDEA...AND WILL HAVE TO WATCH THIS IN FUTURE SHIFTS.

&&

.AVIATION...
MVFR CEILINGS WILL PERSIST THROUGHOUT THE AREA TODAY.  A WEAK
SHORTWAVE WILL ROTATE THROUGH THE REGION TODAY CREATING AREAS OF
LIGHT SNOW...MAINLY ALONG AND EAST OF THE JAMES RIVER VALLEY.
TEMPERATURES NEAR KSUX WILL BE WARM ENOUGH THAT ANY PRECIPITATION
WOULD BE RAIN MIXED WITH SNOW IF NOT RAIN ALTOGETHER. LOW LYING
STRATUS WILL SHIFT EAST OF THE REGION ON SUNDAY.

&&

.FSD WATCHES/WARNINGS/ADVISORIES...
SD...NONE.
MN...NONE.
IA...NONE.
NE...NONE.
