.SHORT TERM...(TODAY THROUGH TUESDAY NIGHT)
ISSUED AT 357 AM MST SUN JAN 26 2014
MORNING WATER VAPOR IMAGERY TRACKING TWO DISTINCT AND WELL-
DEFINED ALBERTA CLIPPERS DIVING SOUTHEAST WITHIN NORTHWEST FLOW.
THE LEADING SHORTWAVE CURRENTLY MOVING THRU THE DAKOTAS HAS NOT
HAD MUCH NOTICEABLE IMPACT ON THE CWFA THUS FAR. THE MAIN FOCUS
WILL BE THE TRAILING SYSTEM WHICH WAS AMPLIFYING ACROSS SRN CANADA
THIS MORNING. THE SFC FRONT ASSOCIATED WITH THE STRONGER SECONDARY
SHORTWAVE WAS JUST BEGINNING TO ENTER NRN MONTANA AS OF 10Z. THIS
FTR WILL ACCELERATE AND RACE SOUTH INTO THE CWA BY EARLY THIS
AFTERNOON. ITS INITIAL IMPACT WILL BE FELT IN THE WAY OF STRONG
NORTH/NORTHWEST WINDS IN ITS WAKE. MODELS PROG THE STRONGEST
RIBBON OF WINDS TO FALL EITHER SIDE OF A LUSK TO SIDNEY LINE.
GUSTS TO NEAR 50 MPH ARE EXPECTED THIS AFTERNOON...ESPECIALLY
ALONG EXPOSED RIDGE-TOPS WITHIN THE PINE RIDGE. AS A RESULT...HAVE
HOISTED A WIND ADVISORY FOR THE WESTERN NEBRASKA PANHANDLE IN
EFFECT FROM 9 AM THROUGH 9 PM. THE OTHER FOCUS WILL THIS SYSTEM
WILL BE A PERIOD OF LIGHT SNOW BEGINNING AS EARLY AS MIDDAY TODAY
ACROSS NORTHERN ZONES. THIS AREA OF SNOW WILL SPREAD SOUTH ALONG
THE FRONT BY SUNSET. FRONTAL FORCING ALONG WITH OROGRAPHIC
ENHANCEMENT WILL COMBINE WITH THE FAVORABLY DIVERGENT AREA OF THE
RRQ OF A 150 KNOT H3 JET. THE BEST PERIOD OF SNOW WILL LIKELY HOLD
OFF UNTIL THE EVENING AND OVERNIGHT HOURS. ACCUMULATIONS WILL
REMAIN LIGHT...WITH GENERALLY 1 TO 3 INCHES AT ELEVATIONS ABOVE
5000 FEET. AREAS ABOVE 8000 FEET MAY SEE 3 TO 6 INCHES OF NEW SNOW
FROM THIS SYSTEM. IN EITHER CASE...DO NOT ANTICIPATE THE NEED FOR
ANY WINTER HIGHLIGHTS. SNOW WILL LIKELY LINGER FOR A TIME ON
MONDAY...BEFORE DISSIPATING ON MONDAY AFTERNOON. HEIGHTS RISE
RAPIDLY FOR TUESDAY NIGHT AND WEDNESDAY AS FLOW BEGINS TO TURN
MORE ZONAL. THIS WILL INDUCE A DEVELOPING LEE-SIDE PRESSURE TROUGH
AND RESULTANT TIGHTENING GRADIENT OVER THE WIND CORRIDOR. SUSPECT
WINDS WILL BE TRENDING UPWARD...BUT STILL BELOW HIGH WIND CRITERIA
BY TUESDAY NIGHT.
THE OTHER STORY WITH THIS EVENT WILL BE THE RETURN TO COLD
TEMPERATURES. ALTHOUGH TEMPERATURES WILL BE COOLER TODAY WITH
HIGHS IN THE 30S AND 40S...MONDAY WILL RETURN TO MUCH COLDER
BEHIND THE COLD FRONTAL PASSAGE. H7 PROGS OF -20C TO -24C WILL
ONLY YIELD HIGHS MOSTLY IN THE SINGLE DIGITS AND TEENS. CLEARING
SKIES AND A FRESH SNOWPACK WILL MAKE MONDAY NIGHT THE COLDEST
NIGHT WITH MOST PLACES BELOW ZERO. WOULD NOT BE SURPRISED IF
FORECAST LOWS STILL ARENT COLD ENOUGH MONDAY NIGHT. TEMPERATURES
REBOUND QUICKLY INTO THE 20S ON TUESDAY AS HEIGHTS RISE.
.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 357 AM MST SUN JAN 26 2014
THE MODELS SUGGEST PERIODS OF UNSETTLED WEATHER COULD BE IN STORE
FOR THE EXTENDED PERIOD. MOIST NORTHWESTERLY FLOW ALOFT WILL RESULT
IN INCREASING CHANCES OF OROGRAPHIC SNOW OVER THE SIERRA MADRE AND
SNOWY RANGES ON WEDNESDAY. COULD BE VERY WINDY ACROSS THE WIND
PRONE AREAS AS THE GFS SHOWS 700MB WEST WINDS OF AROUND 50 KTS.
FROPA OCCURS ON WED NIGHT WITH SNOW CHANCES SPREADING OVER THE
PLAINS. AT THIS TIME ACCUMULATIONS APPEAR LIGHT OUTSIDE OF THE
MTNS. MODEL SPREAD BETWEEN THE GFS AND ECMWF BEGINS TO DEVELOP BY
THURSDAY AND REALLY CONTINUES INTO THE WEEKEND. THE ECMWF HAS
WIDESPREAD QPF ACROSS THE REGION ON THURS WITH THE FRONT WELL SOUTH
OF THE CWA AND ISENTROPIC ASCENT CONTINUING. THE GFS HAS LARGELY
WESTERLY DOWNSLOPE FLOW. FLOW ALOFT BECOMES MORE ZONAL BY FRI AND
SAT WITH A SERIES OF SHORTWAVES MOVING THROUGH. FORCING FOR PRECIP
WILL BE NORTH OF A BOUNDARY THAT THE MODELS GENERALLY HAVE DRAPED
ACROSS THE NORTHERN ZONES. WITH DIFFERENCES ON SHORTWAVE TIMING IN
ADDITION TO THE LOCATION OF THE BOUNDARY...JUST WENT WITH SLIGHT
CHANCE TO LOW END CHANCE POPS FROM THURS THROUGH SAT. TEMPS WILL BE
WARMEST ON WED...HOWEVER IT DOES NOT LOOK LIKE IT WILL BE TOO COLD
AT ANY TIME DURING THE EXTENDED.
