235 PM MST WED JAN 9 2013
.DISCUSSION...WATER VAPOR IMAGERY SHOWS BROAD UPPER RIDGING ACROSS
THE CENTRAL CONUS WITH A DEEP TROUGH PUSHING TOWARD THE PACIFIC
COAST. SURFACE ANALYSIS SHOWS STRONG HIGH PRESSURE OVER THE CENTRAL
PLAINS WITH DEEP WEST/SOUTHWESTERLY FLOW ACROSS THE NORTHERN PLAINS.
TONIGHT...UPPER TROUGH WILL PUSH ACROSS THE WESTERN PACIFIC COAST
WITH FLOW ALOFT BECOMING MORE SOUTHWESTERLY. BROAD SURFACE LOW
PRESSURE WILL STRENGTHEN ACROSS EASTERN MONTANA. SKIES WILL REMAIN
MOSTLY CLEAR OVER MOST LOCATIONS OVERNIGHT. THE MAIN ISSUE TONIGHT
WILL BE DOWNSLOPING WINDS ACROSS THE BLACK HILLS. SIX MB SURFACE
PRESSURE GRADIENT WILL DEVELOP ACROSS THE HILLS THIS EVENING. 12Z
MODEL RUNS CONTINUE TO SHOW BOUNDARY LAYER WINDS OF 50 KT WINDS LATE
TONIGHT ACROSS THE CENTRAL TO NORTHERN BLACK HILLS INTO THE BEAR
LODGE MOUNTAINS. STRONG DOWNSLOPING WILL DEVELOP ALONG THE FOOTHILLS
FROM THE SPEARFISH AREA TO STURGIS TO PIEDMONT AND PERHAPS BLACK
HAWK AREAS. WINDS ARE EXPECTED TO REACH 35 TO 45 MPH WITH GUSTS TO
60 MPH...SO WILL UPGRADE WATCH TO HIGH WIND WARNING ACROSS THOSE
AREAS. THINK WESTERN PARTS OF RAPID CITY OVER HIGHER ELEVATIONS WILL
SEE GUSTY WINDS AS WELL...BUT NOT TO THE EXTENT OF FARTHER
NORTHWEST. SO WILL ISSUE A WIND ADVISORY FOR RAPID CITY TONIGHT.
WINDS WILL QUICKLY DECREASE EARLY TOMORROW MORNING AS THE PRESSURE
GRADIENT RELAXES.
THURSDAY...QUIET WEATHER IS EXPECTED AS THE UPPER TROUGH DEEPENS
OVER THE GREAT BASIN AND CONTINUES ITS PUSH EASTWARD. CLOUDS WILL
INCREASE FROM THE WEST...AND TEMPS ARE EXPECTED TO REACH THE UPPER
30S TO LOWER 50S ACROSS THE PLAINS...AND MID TO UPPER 50S ACROSS
THE DOWNSLOPING EASTERN HALF OF THE FOOTHILLS.

CENTERED OVER THE GREAT BASIN INTO SOUTHWESTERN WYOMING. STRONG
SURFACE LOW PRESSURE WILL DEVELOP ACROSS THE REGION. SNOW WILL START
PUSHING IN FROM THE WEST LATE THURSDAY NIGHT INTO FRIDAY MORNING AS
THE UPPER LOW REDEVELOPS NEAR THE CWA. SNOW WILL THEN SPREAD ACROSS
MUCH OF THE CWA THROUGH THE DAY FRIDAY AS A TRAWL SET UP OVER THE
CWA. THERE REMAINS UNCERTAINTY AS TO HOW MUCH SNOW THE AREA WILL
GET. MODELS ARE SHOWING 6 INCHES OF ACCUMULATION POSSIBLE ACROSS
SOME PARTS OF THE DAKOTAS...BUT THERE IS INCONSISTENCY AS TO WHERE
THIS WILL FALL. THE 12Z GFS PUSHES THE HIGHEST QPF FARTHER
EAST...EAST OF THE BLACK HILLS AREA WHILE THE NAM AND ECMWF SHOW THE
MAIN AXIS OVER THE BLACK HILLS TO NORTHWEST SOUTH DAKOTA. ITS
POSSIBLE THERE WILL BE AN IMPROVEMENT IN CONSISTENCY WITH THE MODEL
RUNS TONIGHT AS WE GET BETTER UPPER AIR SAMPLING WITH THE TROUGH
MOVING ONSHORE. BLOWING SNOW WILL ALSO BE A CONCERN WITH NORTHWEST
WINDS EXPECTED TO INCREASE FRIDAY TO 25 TO 35 MPH WITH HIGHER GUSTS.

FALLING THROUGH THE DAY FRIDAY AND INTO FRIDAY NIGHT. IN ADDITION TO
SNOW AMOUNTS...BLOWING SNOW...VERY COLD WIND CHILLS WILL ALSO BE A
CONCERN ESPECIALLY LATE FRIDAY INTO FRIDAY NIGHT AS TEMPS DROP WELL

CURRENT WINTER WEATHER HEADLINES.

SNOW ENDING AND WINDS GRADUALLY DECREASING DURING THE DAY. CANADIAN
HIGH PRESSURE WILL SETTLE ACROSS THE AREA BY SATURDAY EVENING...WITH
VERY COLD AIR REMAINING ACROSS THE REGION THROUGH THE WEEKEND AND
INTO EARLY NEXT WEEK. WEAK DISTURBANCES IN NORTHWESTERLY FLOW ALOFT
WILL LIKELY TRACK ACROSS THE AREA NEXT WEEK AS MILDER AIR TRIES TO
PUSH IN. THE MAIN CHANCES FOR SNOW WITH THESE DISTURBANCES WILL BE
ACROSS FAR NORTHEASTERN WY...THE BLACK HILLS...AND FAR NORTHWESTERN
SD.
