NATIONAL WEATHER SERVICE SIOUX FALLS SD
1120 AM CDT FRI APR 3 2009

.DISCUSSION...
HAVE MADE SOME MINOR ADJUSTMENTS TO DEW POINTS AND WINDS TO MATCH UP
BETTER WITH CURRENT TRENDS. OVERALL...LOWERED DEW POINTS IN THE EAST
AND RAISED WINDS IN THE WEST AS LOW PRESSURE DEEPENS IN EASTERN
WYOMING.

ACTIVE FORECAST WITH UPPER LEVEL TROUGH CURRENTLY MOVING INTO THE
CENTRAL ROCKIES...AND PULLING INTO THE PLAINS THIS WEEKEND.
EXTREMELY STRONG FRONTOGENESIS PROGGED AROUND 700 MB SOUTH OF
INTERSTATE 90 WILL RESULT IN PRECIPITATION SATURDAY AFTERNOON INTO
SATURDAY NIGHT. MODELS SUGGESTING ATMOSPHERE MAY BECOME UNSTABLE
ABOVE FRONTOGENETIC LAYER LATE SATURDAY AFTERNOON INTO SATURDAY
NIGHT...ESPECIALLY DOWN NEAR THE YANKTON TO SPENCER IOWA AREA. THIS
MAY RESULT IN THE POTENTIAL FOR LOCALIZED BANDING.  NAM AND GFS
COLDER THAN THE ECMWF IN TERMS OF THERMODYNAMIC PROFILES...BUT THE
OVERALL NET RESULT IS THAT EXPECT PRECIPITATION TO CHANGE OVER TO
SNOW QUICKER THAN PREVIOUSLY ANTICIPATED. HAVE THEREFORE INCREASE
SNOW TOTALS...ESPECIALLY ALONG AND SOUTH OF INTERSTATE 90. WENT
AHEAD AND UPGRADED TO A BLIZZARD WARNING FOR SOUTHERN CWA WITH
STRONG EASTERLY WINDS TRANSITIONING TO NORTHERN THE BACKSIDE OF THIS
SYSTEM. FOR NOW...KEPT WATCH TO THE NORTH AND EXPANDED WATCH TO

.PREV DISCUSSION...
ONSET OF LGT PCPN AHD OF MAJOR SYS TDA AND TNGT LOOKS A LTL SLOWER
THAN WE HAD GONE PREVIOUSLY...BUT STILL THERE WILL BE A STEADY
INCREASE IN THE THREAT TNGT...AS WELL AS AN INCRS IN THE THREAT OF
PCPN GOING TO SNOW N LATE. MODELS ALL SHOW STG COOLING AS PCPN BCMS
WIDESPREAD SAT AND DYNAMICS GET STRONG. ASSUMING THE THREAT OF
WDSPRD MDT TO HVY PCPN IS THERE...IT SEEMS BEST TO GO WITH THIS
WORST CASE SCENARIO...ASSUME THE MODEL COOLING IS RIGHT...AND GO FOR
A LTL FASTER CHANGEOVER TO SNOW. THIS WILL LEAD TO WDSPRD SNOW OVER
FCST AREA SAT NGT XCP MAYBE A LINGERING THREAT OF MIXED PCPN FAR SE.
GUIDNCE QPFS SEEM A LTL OVERDONE WHICH JUST MEANS WITH THIS FASTER
CHANGEOVER WE WILL BE GOING WITH 6 TO 10 INCHES OF SNOW ALONG AND S
OF I90 INSTEAD OF A FOOT PLUS. ENUF UNCERTAINTIES REMAIN IN TRACK
AND STRENGTH OF SYS TO KEEP WATCH AS IS...THAT IS NOT TO START A
WARNING IN LATE THIRD/FOURTH PD. A SHIFT FRTHR N WHICH STILL SEEMS
PSBL CUD CUT DOWN AMTS OVER SERN CRNR OF FCST AREA IN NWRN IA WHILE
A TRACK FRTHR S CUD LEAVE THE I90 AREA WITH RELATIVELY LOW AMOUNTS.
EXPECT A FOOT OF SNOW SOMEWHERE BUT THIS CUD BE A FAIRLY NARROW
BAND.

WINDS WILL PICK UP STRONGLY WITH SYS SAT NGT SO WILL KEEP BLOWING
SNOW MENTN MAINLY S AND E. SNOW SHUD DCRS STEADILY SUN AS THERE
APPEARS NO REASON FOR A STALL OR SEMI STALL.

ESSENTIALLY NO CHANGE TO MON THRU THU FCST WITH A WARMING
