What happened

The episode as NWS ABR wrote it up.

A major winter storm moved across the Northern Rockies and into the Northern Plains producing from 2 to 22 inches of snowfall along with widespread blizzard conditions. Most area schools and events were canceled. Travel was extremely difficult and not advised. Interstate 29 from Watertown to the North Dakota line and Interstate 90 across Jones and Lyman counties were both closed during the storm. There were several vehicle accidents with no serious injuries reported. However, this storm took a toll on area ranchers as calving season was underway. Storm total snowfall amounts included; 6 inches in Blunt, Timber Lake, Gettysburg, and Wilmot; 7 inches in Doland and Pierre; 8 inches in Clark, Clear Lake, Leola, Hosmer, Gettysburg, southeast of McIntosh, and Kennebec; 9 inches south of Bristol, Waubay, and near Chelsea; 10 inches in Eagle Butte and Mobridge; and 11 inches in Pollock and Turton. Locations with a foot or more of snowfall included; 12 inches in Aberdeen, Britton, Andover, Sisseton, and Faulkton; 13 inches at Lake Sharpe, Roy Lake, and eight miles southwest of Keldron; 14 inches in Miller, Redfield, and Webster; 15 inches near Highmore and near Columbia; 16 inches southwest of Stratford; 17 inches 14 miles northeast of Isabel; 20 inches in McLaughlin, Ree Heights, and 4 miles northeast of Victor with almost 22 inches northwest of Stephan.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ABERDEEN SD
912 PM CDT SUN MAR 29 2009

.UPDATE...
WSR-88D IS FILLING IN ABOUT AS EXPECTED. WATER VAPOR IMAGERY
CLEARLY SHOWS THE UPPER LEVEL LOW MOVING INTO WYOMING AND THE
LATEST SURFACE OBSERVATIONS SHOW THE SURFACE LOW MOVING INTO
SOUTHWEST SOUTH DAKOTA. AGAIN ALL ARE ABOUT AS EXPECTED.
TEMPERATURES ARE FALLING ON SCHEDULE SO NO CONCERNS THERE EITHER.
NO UPDATES ARE PLANNED AT THIS TIME.

&&
.PREV DISCUSSION...
.SHORT TERM...TONIGHT THROUGH 00Z WEDNESDAY
BIGGEST WEATHER CONCERN THROUGH THE SHORT TERM DEALS WITH
IMPENDING SPRING SNOW STORM...SNOWFALL TOTALS...AND DURATION.

MODELS REMAIN CONSISENT WITH THE HANDLING OVER OVERALL FEATURES.
CURRENT 500HPA AND 700HPA WAVES ARE DROPPING INTO THE
MIDWEST...WITH DEVELOPING BAROCLINIC LEAF SEEN ON THE IR SAT PIX.

DURING THE DAY MONDAY...STRONG 850HPA-700HPA FRONTOGENESIS SETS UP
ACROSS THE NORTHERN CWA...WITH WELL DEFINED AREA OF OMEGA LOCATED
WITHIN AREA OF FRONTOGENESIS. 850HPA-700HPA SPEC HUMIDITIES RANGE
FROM 3G/KG TO 4 G/KG DURING THE DAY MONDAY...WITH CONVERGENCE ZONE
LOCATED ALONG THE NRN COUNTIES. STRONG 85H AND 7H THETA-E FORCING
CONTS THROUGH THE DAY MONDAY. N-S CROSS SECTIONS ALONG THE JAMES
RIVER VALLEY...FOR 18Z MONDAY...SHOW HINTS OF CONVECTIVE
POSSIBILITY IN THE KABR AREA...WITH OVER 100 UNITS OF
FRONTOGENETIC FORCING...AND NEG EPV* LOCATED ABOVE THE
FORCING...ALONG WITH OMEGA LOCATED THROUGH THE LAYER. COULD SEE
SOME CONVECTIVE SNOWFALL TOTALS THAT BECOME RATHER IMPRESSIVE
THROUGH THE DAY MONDAY ALONG HIGHWAY 12. ALSO AIDING IN UPWARD
MOTION IS THAT BOTH MODELS PLACE CWA IN A COUPLE JET STRUCTURE
ALOFT WITH DIVERGENCE ALOFT ADVERTISED THROUGH THE PERIOD. ONE
POSSIBLE CONCERN IS THE WINDS. ADVERTISED WINDS RIGHT NOW REFLECT
LOW END BLIZZARD CONDITIONS...OR HIGH END WINTER STORM CONDITIONS.
NO REAL STRONG CAA PUSH BEHIND THIS FEATURE...AND NO ADVERTISED
STRONG PRESSURE RISES EITHER. COULD SEE 1/4SM VSBYS DUE TO FALLING
SNOW...BUT NOT SURE BLSN WILL BE STRONG ENOUGH FOR 1/4SM VSBYS.
HOWEVER...WITH BLIZZARD WARNING ALREADY IN PLACE...WILL JUST
CONTINUE WITH THAT THOUGHT PROCESS AND SEE WHAT SHAKES OUT.

AS THIS FEATURE DROPS INTO NEB...IT DEEPENS. THE NAM ADVERTISES A
527HPA LOW NEAR SUX AT 18Z TUESDAY...WITH THE GFS A BIT FURTHER
EAST...IN NWRN IA BY 18Z TUESDAY...BUT HAS A 526HPA CLOSED LOW.
BOTH MODELS THOUGH LIFT THIS FEATURE NNE THROUGH THE DAY
TUESDAY...KEEPING ERN SD IN A WELL DEFINED TROWAL ZONE THROUGH THE
DAY TUESDAY. 85H-7H FRONTOGENESIS ALSO TAKES PLACE NW OF DEEPING
SFC LOW...AND 85H/7H THETA-E FORCING CONTINUES THROUGH THE DAY
TUESDAY. AS COLDER AIR PUSHES IN FROM THE WEST WITH THE
SYSTEM...MAY STAND A BETTER CHANCE OF SEEING STRONGER WINDS ACROSS
THE EAST DURING THE DAY TUESDAY. HAVE OPTED TO REPLACE CURRENT
BLIZZARD WATCH WITH A BLIZZARD WARNING FOR THE ERN CWA. GIVEN
FRONTOGENETIC FEATURES/OMEGA/MOISTURE IN PLACE...ALSO WOULDNT BE
SURPRISED TO SEE SOME CONVECTIVE SNOWBANDS SET UP ACROSS THE ERN
CWA DURING THE DAY TUESDAY.

AS FOR SNOWFALL TOTALS...HAVE GONE CONSERVATIVE ON TOTALS BY
BACKPEDDLING ON HPC QPF GRIDS THAT WERE BROUGHT IN. THIS STILL
RESULTS IN RATHER IMPRESSIVE SNOWFALL TOTALS FROM 00Z MONDAY
THROUGH 00Z WEDNESDAY. SEEMS TO BE SIMILAR IN A FEW WAYS TO APRIL
BLIZZARD THAT AFFECTED THE I-29 CORRIDOR LAST APRIL.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY

THE STORM SYSTEM SET TO EFFECT THE REGION DURING THE SHORT TERM
PERIOD WILL CONTINUE TO HANG ON IN THE EAST WELL INTO WEDNESDAY.
GUIDANCE THEREAFTER IS IN FAIRLY CLOSE AGREEMENT OVER THE LONGWAVE
PATTERN WITH EMBEDDED SHORTWAVES THROUGH NEXT WEEKEND. MAJOR
FEATURES THIS TIME FRAME ARE THE PERSISTENT UPPER TROUGH OVER THE
CWA...WITH A SHORTWAVE THAT MOVES SOUTH OF THE CWA FOR NEXT
WEEKEND. GUIDANCE SUGGESTS SOME PRECIPITATION WILL MANAGE NORTHWARDS
INTO THE CWA...BUT THE MINOR DIFFERENCES BETWEEN DETERMINISTIC GFS/ECMWF
MAKE NAILING DOWN SNOWFALL ACCUMULATIONS IMPOSSIBLE.

AS FOR TEMPERATURES...NAEFS LACKS SPECIFIC ANOMALIES IN THE
H85/H925 LAYER...BUT BEING BASED UNDER AN UPPER TROUGH IT STANDS
TO REASON THERE WILL BE LITTLE IF ANY SIGNIFICANT WARM UP DURING
THIS TIME FRAME. ADDITIONALLY...SNOW COVER WILL HAVE DRASTIC LOCAL
EFFECTS ON AREA TEMPERATURES...KEEPING US WELL BELOW NORMAL.

&&

.AVIATION...
THE SNOW AND LOW CLOUDS ASSOCIATED WITH THE FIRST ROUND OF THE
APPROACHING STORM IS MOVING INTO EASTERN SOUTH DAKOTA NOW.
LOWERING CONDITIONS WILL MOVE NORTHEAST ACROSS THE STATE TONIGHT.
BY MORNING ALL LOCATIONS ARE EXPECTED TO BE IFR OR LIFR. THESE IFR
CONDITIONS FRO CEILINGS AND VISIBILITY WILL LAST THROUGH TOMORROW
EVENING. WIND WILL ALSO BE AN ISSUE LATER TONIGHT AND TOMORROW
WITH GUSTS ALREADY IN THE 25 TO 35 KT RANGE IN PARTS OF CENTRAL
SOUTH DAKOTA. THEY WILL ALSO REMAIN THROUGH TOMORROW.
