A COLD FRONT WILL CONTINUE TO MARCH THROUGH THE AREA TONIGHT RESULTING IN DETERIORATING CONDITIONS THROUGH THE MORNING. EXPECT A PERIOD OF -SN DURING THE MORNING HOURS ON TUESDAY AT BOTH KRWL AND KLAR WHERE CONDITIONS MAY EVEN DROP INTO THE IFR CATEGORY FOR A TIME. A PERIOD OF -SN IS ALSO BE POSSIBLE KCYS THIS MORNING AS THIS AREA OF SNOW SPILLS INTO ADJACENT EASTERN FOOTHILLS. MAY EVEN SEE -SN REACH INTO THE WESTERN NEBRASKA PANHANDLE TERMINALS THOUGH CONFIDENCE IS LESS...SO ONLY ADDED VCSH FOR NOW. THE -SN WILL DEPART THIS AFTERNOON WITH CONDITIONS SLOWLY IMPROVING THEREAFTER. && .PREV DISCUSSION... /ISSUED 930 PM MST MON JAN 23 2012/ .UPDATE... SHORTWAVE ENERGY CONTINUES TO SPLIT AS IT SPINS EAST INTO THE ROCKIES THIS EVENING. THE DOMINANT SHORTWAVE WILL PUSH ACROSS THE FOUR CORNERS ON TUESDAY...WHILE THE NORTHERN SHORTWAVE RACES ALONG THE CANADA/U.S. BORDER. IN BETWEEN...A WEAK SFC COLD FRONT WILL PUSH THROUGH SE WYOMING/WRN NEBRASKA LATE TONIGHT/EARLY TUESDAY. STILL LOOKS LIKE COOLER AIR WILL BE USHERED IN ALONG WITH A PERIOD OF LIGHT SNOW. DID NOT MAKE SIGNIFICANT CHANGES TO THE SNOW AMOUNT FORECAST WITH GENERALLY 3 TO 6 INCHES IN THE SNOWY/SIERRA MADRE/LARAMIE RANGES...1 TO 3 INCHES FOR ELEVATIONS BELOW 7500 FEET WEST OF THE LARAMIE RANGE...AND LESS AN INCH OUT ON THE EASTERN PLAINS. .PREV DISCUSSION... /ISSUED 129 PM MST MON JAN 23 2012/ SHORT TERM...TONIGHT THROUGH THURSDAY MORNING... FORECAST CHALLENGES DEAL WITH SNOW ACCUMULATIONS WITH A WEAK SYSTEM TONIGHT THROUGH TUESDAY AND THEN STRONG WIND POSSIBILITY TUESDAY NIGHT THROUGH THURSDAY. CURRENTLY...ARCTIC BOUNDARY LIES ACROSS WESTERN SOUTH DAKOTA BACK INTO CENTRAL MONTANA THIS AFTERNOON. SURFACE HIGH PRESSURE OVER SOUTHEAST WYOMING AND NORTHERN COLORADO HAS KEPT WINDS FAIRLY LIGHT COMPARED TO WHAT WE HAVE BEEN SEEING. STILL GUSTY IN OUR WIND PRONE AREAS...BUT WELL BELOW HEADLINE CRITERIA. FURTHER WEST...A PACIFIC STORM SYSTEM MOVING INTO THE CALIFORNIA SIERRAS INTO NEVADA. SYSTEM HAS SPLIT AS FORECAST WITH MAIN ENERGY OVER SOUTHERN CANADA AND THE SYSTEM OVER CALIFORNIA PUSHING SOUTHEAST. SHORT RANGE MODELS SHOWING A WEAK FRONT MOVING INTO THE AREA TONIGHT WITH INCREASING POPS ACROSS CARBON AND WESTERN CONVERSE COUNTIES. FRONT FORECAST TO BE POSITIONED ROUGHLY FROM CHADRON TO JUST NORTH OF RAWLINS BY TUESDAY MORNING 12Z. FRONT THEN FORECAST TO MOVE THROUGH SOUTHEASTERN WYOMING DURING THE LATE MORNING. WILL MOST LIKELY HAVE OUR MAX TEMPERATURES HERE AT CHEYENNE IN THE MORNING...WITH STEADY OR SLOWLY FALLING TEMPERATURES THROUGH THE DAY.

ELSEWHERE...NORTHERN CARBON COUNTY SHOULD SEE AN INCH OR SLIGHTLY HIGHER WITH A HALF INCH OR LESS EAST OF THE LARAMIE RANGE. DECIDED TO HOLD OFF FOR NOW ON ANY ADVISORIES FOR THE SNOWY...SIERRA MADRE AND NORTHERN LARAMIE RANGES AS THEY SHOULD FALL JUST SHORT OF 6 INCHES. BUT THE EVENING SHIFT WILL NEED TO REASSESS WITH THE 00Z FORECAST RUN. GOOD THING WITH THIS SYSTEM IS THAT WINDS ARE FORECAST TO BE QUITE WEAK TUESDAY...SO WE DO NOT HAVE TO WORRY ANY ABOUT BLOWING/DRIFTING SNOW. THIS SYSTEM MOVES THROUGH TUESDAY AFTERNOON WITH STRONG RIDGING BUILDING IN OVERNIGHT INTO WEDNESDAY. GFS SHOWING 700MB WINDS RAPIDLY INCREASING TUESDAY NIGHT TO 45-50KTS AS THE RIDGE BUILDS IN AND THE CRAIG TO CASPER 700MB GRADIENT INCREASING TO 60MTRS AFTER 06Z. LOCAL WRKHGT PRODUCT SHOWS 70MTRS/49MTRS AT 850 AND 700MB RESPECTIVELY BY WEDNESDAY AFTERNOON...SO LOOKS LIKE ANOTHER POSSIBLE WIND EVENT BY WEDNESDAY AFTERNOON. HAVE ADJUSTED OUR USUAL WIND PRONE AREAS UP IN WIND SPEEDS BEGINNING LATE TOMORROW NIGHT THROUGH WEDNESDAY NIGHT. WE STILL HAVE A LITTLE TIME ON ANY WATCHES AND WILL LET THE MID SHIFT TAKE ANOTHER LOOK AT THINGS. WILL CONTINUE HIGH WIND WORDING IN THE HWO. STRONG AND GUSTY WINDS LOOK TO CONTINUE INTO THURSDAY. .LONG TERM...THURSDAY NIGHT THROUGH MONDAY... RATHER PROGRESSIVE PATTERN EXPECTED TO CONTINUE ACROSS THE REGION THIS PERIOD WITH A COUPLE OF UPPER SYSTEM AFFECTING THE AREA. THE FIRST SHOULD SCOOT ACROSS THURSDAY NIGHT INTO FRIDAY AND BRING SIMILAR EFFECTS TO THE LAST FEW SYSTEMS...A SHOT OF LIGHT PRECIPITATION AND COOLER AIR. PCPN CLEARING OUT FRIDAY MORNING/EARLY AFTERNOON AS UPPER TROF AXIS PASSES BY LEAVING NW FLOW OVER THE CWA IN ITS WAKE. NUDGED MAXS DOWN A BIT FOR FRIDAY AS COOLER AIR SEEMS A BIT UNDERDONE BY MODELS. SLOW WARMUP THEN ENSUES FOR SATURDAY AND SUNDAY AS HEIGHTS RISE SLOWLY. NEXT UPPER SHORTWAVE WILL APPROACH ON MONDAY AND SHOULD INCREASE SOME MTN SNOW SHOWERS THEN. IN THE MEANTIME THERE WILL BE PERIODS OF ENHANCED WINDS AROUND THE MTNS AS LEE TROFFING DEVELOPS AT TIMES BUT NO BIG WIND EVENTS ANTICIPATED. && .FIRE WEATHER... MINIMAL FIRE WEATHER CONCERNS.
