.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY NIGHT)
ISSUED AT 337 PM MDT MON MAR 10 2014
FORECAST CHALLENGES DEAL WITH SNOW AMOUNTS TONIGHT THROUGH TUESDAY
ACROSS THE AREA.
CURRENTLY...NEXT FRONTAL SYSTEM PUSHING INTO WESTERN IDAHO THIS
AFTERNOON. SOUTHEAST WYOMING AND NEBRASKA PANHANDLE THIS AFTERNOON
SEE LEE SIDE TROUGHING WITH GENERALLY MID TO HIGH LEVEL CLOUDS OVER
THE AREA. THESE CLOUDS HAVE HELD DOWN TEMPERATURES SOMEWHAT THIS
AFTERNOON...WITH MID 50S BEING REPORTED IN SOUTHEAST WYOMING AND
SOME 60S IN THE PANHANDLE. THE LEE SIDE TROUGHING THOUGH HAS
INCREASED OUR WINDS SOME WITH WINDS GUSTING INTO THE 40S ACROSS
SOUTHEAST WYOMING. ONE TROUBLE SPOT IS IN THE ARLINGTON
ZONE...ZONE 110...WHERE HALLECK RIDGE HAS BEEN GUSTING IN THE
UPPER 60S TO NEAR 70MPH. BEING THIS IS THE ONLY SITE HITTING HIGH
WIND WARNING CRITERIA...WILL CONTINUE HANDLING WITH AN SPS.
GUIDANCE SHOWING WINDS EASING AFTER 3 PM THIS AFTERNOON AND WE
SHOULD SEE THESE STRONG WINDS EASING.
LATEST 12Z GUIDANCE CONTINUES TO SHOW THE COLD FRONT MOVING INTO
OUR NORTHERN COUNTIES AROUND 12Z TUESDAY. GIVEN THE LATE START ON
THE FRONT MOVING INTO THE AREA AND THE FAIRLY WARM NATURE OF THE
AIRMASS WITH THIS FRONT...AM NOT TOO CONCERNED WITH SIGNIFICANT
SNOW ACCUMULATIONS OUTSIDE OF THE MOUNTAINS. THIS SYSTEM LOOKS
SIMILAR TO THE FRONT THAT WENT THROUGH US LAST WEEK...WHERE WE
ONLY RECEIVED AN INCH OR SO OF SNOW WITH A RAIN/SNOW MIX THROUGH
THE DAY. EVENING AND OVERNIGHT SHIFTS CAN TAKE ANOTHER LOOK AT
EXPANDING THE ADVISORY...BUT FEEL PRETTY CONFIDENT THAT NOT A
WHOLE LOT OF SNOW IS GOING TO FALL AT LOWER ELEVATIONS.
FRONT CLEARS THE SOUTHERN WYOMING STATE LINE AROUND 6 PM TUESDAY
WITH PRECIP ENDING FROM NORTH TO SOUTH. LOOKS LIKE A PRETTY COLD
START FOR WEDNESDAY WITH GFS 700MB TEMPERATURES -8 TO -10C. BY
WEDNESDAY AFTERNOON THOUGH...THEY WARM BACK TO -4C...SO ANY SNOW
THAT DOES FALL SHOULD BE MELTED AS AFTERNOON HIGHS CLIMB INTO THE
40S AT MOST LOCATIONS IN SOUTHEAST WYOMING AND NEAR 50 IN THE
PANHANDLE.
.LONG TERM...(THURSDAY THROUGH SUNDAY NIGHT)
ISSUED AT 337 PM MDT MON MAR 10 2014
THE EXTENDED PERIOD WILL BE DOMINATED BY AN UPPER LEVEL RIDGE
BUILDING OVER THE WESTERN CONUS WITH A FEW SHORTWAVE FEATURES MOVING
OVER THE FORECAST AREA IN NORTHWEST FLOW. ON THURSDAY...THE FIRST
SHORTWAVE WILL MOVE ACROSS THE REGION. LOOKS AS THOUGH IT WILL
PRODUCE MAINLY JUST BREEZY CONDITIONS ACROSS THE CWA AS MOISTURE
ASSOCIATED WITH THIS SYSTEM WILL BE LIMITED. TEMPS WILL BE IN THE
40S AND 50S OUT WEST AND IN THE 50S AND 60S ACROSS THE PLAINS IN
THIS PATTERN. MODELS THEN DIFFER ON THE TIMING OF THE NEXT WEAK
SHORTWAVE PROGGED TO MOVE THROUGH LATE FRIDAY INTO SATURDAY. RUN TO
RUN CONSISTENCY WITH THIS FEATURE IS LACKING AS WELL...SO DID NOT
MAKE ANY RASH CHANGES TO THE ONGOING FORECAST. KEPT A LOW CHANCE FOR
RAIN/SNOW MAINLY FOR SATURDAY AS THE ECMWF DOES PRODUCE A
SIGNIFICANTLY STRONGER AND SLOWER SYSTEM THAN THE GFS. TEMPS WILL BE
A BIT COOLER FOR FRIDAY AND SATURDAY...AND BREEZY TO WINDY
CONDITIONS WILL PERSIST THROUGH THIS TIME. SUNDAY SHOULD SEE
WARMER AND DRIER CONDITIONS IN THE WAKE OF THE DEPARTING
SHORTWAVE...AND POSSIBLY A RETURN OF STRONG WINDS DEPENDING ON
WHICH SOLUTION VERIFIES. ALL IN ALL...LOOKS TO BE A FAIRLY BENIGN
WEATHER PATTERN THROUGH THE WEEKEND WITH WINDS POTENTIALLY THE
MAIN CONCERN.
