AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
940 PM CDT SUN MAR 8 2009

.DISCUSSION...
MAIN FCST ISSUE IS ST AND AREAS OF FOG. SOME ST WILL CONT TO MOVE
ACRS SERN CRNR OF SD AND INTO SWRN MN. DCRS IN ST IN ERN NE AND
APPCHG STGR LO LVL SRLY FLOW SUGGESTS ST WILL NOT BCM REAL EXTENSIVE
THESE AREAS AND DONT EXPECT TOO MUCH FOG. SRN AND ERN AREAS OF NWRN
IA WILL BE A DIFFRNT STORY AS ST AND FOG SHUD SLWLY EXPAND/DVLP MUCH
OF TNGT. ADJUSTED MOST OF TNGTS LOWS UP SLIGHTLY WITH MIXG FLOW
DVLPG...AND EVEN IN NWRN IA MOST OF THE NIGHTS COOLING IS ERY THIS
EVE. OTRW NOTHING EXCITING WITH JUST A LTL INCRS IN HIR CLDS NWRN
FCST AREA BY DAYBREAK.

&&

.AVIATION...
AN AREA OF IFR STRATUS AND/OR DVLPG PATCHY IFR FOG ALG AND SOUTH OF
MISSOURI RIVER EAST OF PICKSTOWN TO SUX AT 02Z SHOULD EXPAND NEWD
OVER MOST OF NWRN IA...FAR SERN SD...AND INTO SRN PARTS OF SWRN MN
THRU 08Z...THEN BREAK UP THRU 15Z OR SO. A CDFNT WILL MOVE SEWD INTO
WRN CWA FM HON TO 9V9 BY 14Z AND THEN MOVE SEWD OVER SERN SD...MOST
OF SWRN MN...AND FAR NWRN IA BY 21Z FLWD BY MVFR CIGS.

&&

.PREV DISCUSSION...
SNOW MELT OVER THE AREA ALLOWING TEMPS TO RISE MORE QUICKLY
THAN ANTICIPATED...BUT SHOULD NOT SIGNIFICANTLY AFFECT LOW TEMPS
TONIGHT. DISSIPATING CLOUD COVER AND LIGHT WINDS WILL ALLOW FOR
RADIATIONAL COOLING...BUT DEWPOINTS IN AND AROUND THE AREA ARE IN
THE UPPER 20S AND LOW 30S...SO EXPECT TEMPS TO SETTLE AROUND THE 30
DEGREE MARK ACROSS MUCH OF THE AREA TONIGHT. EXPECT SOME LIGHT FOG
ACROSS THE REGION EARLY MONDAY MORNING...INCLUDED IN THE TAFS.

ON MONDAY...CDFNT WILL SAG SEWD ACRS CWA STALLING JUST S OF CWA BY
MON EVE. THIS WL MAKE TEMPS FCST PRETTY TRICKY...ESPEC IF FOG AND
STRATUS BECOMES WDSPRD AHEAD OF THIS FNT LATE TONIGHT AND MON MORN.
WL GO A LTL COOLER THAN GUID FOR HIGHS ON MON. EVEN IF FOG DOES NOT
BECOME WDSPRD...ENELY FLOW BEHINF SFC FNT WL NOT FAVOR STG WARMING
EVENING IF COLD AIR IS INIT SHALLOW.

GETS INTERESTING LATER MON NITE INTO TUES. HWVR...CUD SEE PATCHY
L-/ZL- DEVELOPING BEHIND FNT IN THE EVE AS LLM FLOWS N OVER SFC
BNDRY. THEN IT GETS FUN. DIGGING UPPER LOW WL LIFTS NEWD TUES
BECOMING MORE NEGATIVELY TILTED DURING THE DAY. THIS SHUD ALLOW FOR
FAIRLY RAPID DEPENDING OF SFC WAVE OVR IA ALONG WITH ARCTIC AIR
PLUNGING INTO NRN PLAINS. WUD EXPECT PRECIP TO BECOME WDSPRD ESPEC
WRN AND NRN CWA TUES AND THIS WILL BE IN THE FORM OF SNOW. BEST
ISENT LIFT APPEARS TO BE ALONG NRN CWA AND NWD...BUT IF UPPER LOWS
DIGS EVEN MORE...THEN CUD SEE FAIRLY HEAVY SNOW ACRS A LARGE PART OF
CWA ON TUES. EVEN IF HEAVY SNOW STAYS N OF CWA...STRONG NWLY WINDS
WILL INCREASE TO 30 TO 40 MPH FM W TO E ACRS CWA ON TUES AND CUD
CREATE NEAR BLIZZARD CONDITIONS. FOR THIS REASON HAVE ISSUED A
WINTER STORM WATCH ACRS NRN CWA WHERE HEAVIEST SNOW EXPECTED IN THE
3 TO 5 INCH RANGE. AGAIN...MAY HAVE TO EXPAND FURTHER S. LIKELY
SCENARIO WL PBLY NEED SOME SORT OF WINTER WX OR WND ADVYS ACRS REST
OF CWA ON TUES...BUT LATER FCSTS CAN FINE TUNE THAT. HIGH TEMPS ON
TUES WL OCCUR EARLY...AND THEN AS COLD AIR MOVES IN...TEMPS SHUD
SLOWLY FALL. LUCKILY THIS STORM WL NOT REMAIN ACRS THE CWA FOR
LONG...AND WL RAPIDLY PULL AWAY TUES EVE...BUT IT WILL STILL BE
WINDY TUES NITE WITH BITTERLY COLD WIND CHILLS.

WED THRU SUN APPEARS DRY FOR NOW. WL START OUT BLOW NORM ON WED AND
THU WITH A GRADUAL WARMUP FOR THE WEEKEND. MODELS HAVE NOT DONE ALL
THAT WELL IN THE LONG RANGE...SO AM NOT CONFIDENT IN THE WARMUP.
