420 AM MST MON JAN 25 2010
.SHORT TERM...TODAY THROUGH TUESDAY NIGHT...
A 115KT H3 JET EMBEDDED WITHIN NORTHWEST FLOW EXTENDED FROM SE
MONTANA SOUTHEAST THROUGH THE TX/OK PANHANDLES. THE LRQ REGION
WILL TRAVERSE THE PANHANDLE THROUGH THE MORNING AND INTO EARLY
AFTERNOON. AT THE SFC...NEARLY 7 MB OF PRESSURE DIFFERENCE EXISTS
FROM THE NW TO SE CORNER OF THE CWA. THIS HAS CREATED A STRONG
PRESSURE GRADIENT...WHICH WILL FURTHER AID BREEZY TO LOCALLY WINDY
NORTHWEST WINDS. IN FACT...SFC WINDS HAVE ALREADY RESPONDED AT
CHADRON AND SCOTTSBLUFF...WITH SUSTAINED WINDS IN EXCESS OF 30 MPH
OVER THE PAST FEW HOURS. HAVE ISSUED A WIND ADVISORY FOR ALL OF
THE WRN NEBRASKA PANHANDLE IN EFFECT THROUGH 6 PM. THE FAVORABLE
SUBSIDENCE AREA OF THE JET WILL CLEAR THE AREA BY LATE AFTERNOON...
THUS THESE STRONG NORTHWEST WINDS WILL GRADUALLY LESSEN LATE THIS
AFTERNOON. BAND OF CLOUDS MOVING THROUGH IDAHO EARLY THIS MORNING
IS ASSOCIATED WITH THE NEXT SHORTWAVE. THIS SHORTWAVE WILL WEAKEN
AS IT APPROACHES THE CWA TODAY. EVEN SO...DID KEEP SOME SMALL SNOW
CHANCES GOING FOR THE HIGH COUNTRY OF THE SIERRA MADRES/SNOWIES
TODAY. HEIGHTS WILL BUILD TONIGHT AS A WEAKENING SHORTWAVE RIDGE
MOVES OVERHEAD. THE NEXT UPSTREAM SHORTWAVE WILL APPROACH SRN
CALIFORNIA ON TUESDAY BACKING FLOW SOUTHWEST OVER THE REGION. AS
LOW/MID-LEVEL FLOW TURNS SOUTHWESTERLY AND INCREASES TO 30-40
KTS...OROGRAPHIC ASCENT WILL ONCE AGAIN BE ENHANCED ALONG THE WEST
SLOPE TUESDAY AND TUESDAY NIGHT. THESE STRONGER WINDS WILL COMBINE
WITH AN INITIAL PIECE OF ENERGY THAT WILL MOVE THROUGH THE
INTERMOUNTAIN WEST TO AID CHANCES FOR LIGHT SNOW FOR LOCATIONS
ALONG AND WEST OF THE LARAMIE RANGE ON TUESDAY. SNOW CHANCES WILL
SPREAD EAST OUT ONTO THE PLAINS TUESDAY NIGHT. THE NAM/GFS ARE
SIMILAR IN DEPICTING A BAND OF ACCUMULATING SNOW ACROSS CONVERSE
AND NIOBRARA COUNTIES...AS WELL AS THE NRN LARAMIE RANGE. THIS
AREA MAY SEE PERHAPS 1 TO 3 INCHES OF SNOW TUESDAY NIGHT...WITH
PERHAPS 2 TO 4 IN THE SIERRA MADRES/SNOWIES. LITTLE OR NO
ACCUMULATION IS ANTICIPATED ELSEWHERE WITH THIS SYSTEM.

RUN AND BETWEEN MODELS. ALL MODELS SHOW PRECIP CONTINUING FROM THE
OVERNIGHT PERIOD WITH A BAND SETTING UP OVER ZONES EAST OF THE
LARAMIE RANGE AND MOVING SOUTH ACROSS THE CWA DURING WEDNESDAY
BEHIND THE COLD FRONT. ALL THE WHILE...INCREASING WESTERLY FLOW
ALOFT ASSOCIATED WITH A WEAK SHORTWAVE MOVING JUST WEST OF THE
AREA WILL ENHANCE UPSLOPE FLOW ALONG THE WESTERN SLOPES. SO WILL
SEE CONTINUED SNOW SHOWERS OVER THIS REGION THROUGH WEDNESDAY
MORNING. LOW LEVEL WINDS WILL SHIFT TO THE NORTHEAST AS HIGH
PRESSURE BUILDS INTO THE GREAT PLAINS BY WEDNESDAY AFTERNOON SO
WILL SEE A SHIFT OF FOCUS TO THE NORTHERN AND EASTERN SLOPE FOR
BEST CHANCE OF SNOW THROUGH WEDNESDAY NIGHT. BY THURSDAY...BEST
FOCUS FOR LIFT WILL BE SOUTH OF THE AREA SO WILL SEE ONLY A SLIGHT
CHANCE FOR SNOW OVER THE MOUNTAIN PEAKS THROUGH THE DAY AS SFC
HIGH PRESSURE SETTLES INTO THE PLAINS. STRONG NNW FLOW WILL MOVE
OVER THE ROCKIES THURSDAY WITH CONTINUED COOL TEMPERATURES AND
MAINLY SOME HIGH CLOUDS MOVING THROUGH THE AREA. A HIGH AMPLITUDE
UPPER LEVEL RIDGE WILL MOVE TOWARD THE AREA ON FRIDAY WHICH WILL
HELP TO MODERATE TEMPERATURES AND MAINTAIN DRY CONDITIONS THROUGH
THE DAY. RIDGE AXIS WILL PROGRESS ACROSS THE CWA ON SATURDAY
BRINGING EVEN WARMER TEMPS. A SHARP UPPER LEVEL TROUGH WILL MOVE
INTO THE WESTERN US ON FRIDAY NIGHT AND WILL MAKE ITS WAY TOWARD
THE CWA THROUGH THE WEEKEND. MODELS ARE MORE CONSISTENT WITH
MAINTAINING AN OPEN WAVE AS IT MOVES EAST WHICH WILL MEAN FOR A
QUICKER SHOT OF SNOW BEGINNING SUNDAY NIGHT AND CONTINUING THROUGH
MONDAY AS THE PACIFIC FRONT MOVES THROUGH AND COLD AIR ADVECTION
ENHANCES LIFT.
