Area forecast discussion, Nov 27, 3:45 AM MST, 57 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
345 AM MST MON NOV 27 2006
.SHORT TERM...VALID FOR TDY AND TUE...
PERIOD OF WINTERY WEATHER COMING IN THE SHORT TERM. FORECAST
CONCERNS OVER THE NEXT 48 HOURS INCLUDE SNOW...TEMPS AND WIND.
FIRST TEMPS. DEEP/COLD TROF DIGGING ALONG THE PACIFIC COAST
CURRENTLY...WITH SSW FLOW ALOFT OVER SE MONTANA. THOUGH COLDEST
AIR WILL REMAIN NORTH OF US TODAY...A VERY TRICKY TEMPERATURE
FORECAST TODAY AS SFC BOUNDARY WILL LINGER ACROSS THE AREA.
GREATEST PRESSURE FALLS IN NORTH CENTRAL WYOMING GIVE CREDENCE TO
MODELS WHICH SHOW SFC DEVELOPMENT IN THIS AREA THIS AFTN. BURGESS
JCT RAWS A BALMY 24 DEGREES AS OF 3 AM...SO IF S/SW WINDS SFC THIS
AFTN IN OUR SOUTH CENTRAL PARTS WE SHOULD SEE TEMPS JUMP WELL
ABOVE FREEZING. HAVE RAISED EXPECTED HIGHS INTO THE UPPER 30S/
LOWER 40S IN OUR SOUTH PARTS. TO THE NORTH IS A DIFFERENT STORY.
IFR STRATUS DECK HAS BLEEDED INTO THE BILLINGS AREA ON LIGHT NW
WINDS...AND LVM REMAINS SOCKED IN. WITH LIGHT OR NORTHERLY SFC
WINDS TODAY THINK OUR WEST AND NORTH PARTS WILL BE SLOW TO WARM
DESPITE THE STRONGER SOUTHERLY FLOW AT MID LEVELS ON TOP OF THE
SFC COLD AIR. SO HAVE LOWERED EXPECTED HIGHS IN THIS AREA. ARCTIC
AIR FLOODS ARE AREA FROM THE NORTH TONIGHT...AND YES IT IS COLD.
TEMPS AT 3 AM ARE -3/-8F AT GTF/CTB RESPECTIVELY...AND MUCH BELOW
ZERO IN ALBERTA. WOULD EXPECT TEMPS TO FALL INTO THE SINGLE DIGITS
AND LOW TEENS TONIGHT...AND THESE VALUES WILL PROBABLY BE NEAR TUE
HIGHS AS WE CONTINUE TO COLD ADVECT. RECORD LOW OF -8F AT BILLINGS
WEDNESDAY WILL BE CHALLENGED. WINDS WILL KEEP TEMPS FROM FALLING
TOO FAR BELOW ZERO IN THE EAST...DESPITE 850MB TEMPS COLDER THAN
-20C.
ENERGY WILL LIFT OUT OF THE GREAT BASIN TONIGHT AND BRING A
PERIOD OF SNOW TONIGHT INTO TOMORROW AS ARCTIC AIR PLUNGES
SOUTHWARD. WILL GO WITH AN ADVISORY FOR PARK COUNTY AS MID LEVEL
ENERGY WILL OVERRIDE LOW LEVEL CONVERGENCE IN THE AREA. WOULD
EXPECT AN EASTERLY WIND TO PERSIST IN LVM TODAY...POORLY FORECAST
BY THE NAM SO HAVE SIDED WITH THE GFS. NORTHERLY ORIENTATION OF
SFC GRADIENT SHOULD FAVOR THE PARADISE VALLEY AS WELL. HAVE
PAINTED 3 INCHES IN THIS AREA TONIGHT. COMBINATION OF MARGINAL
ADVY SNOW AND EXPECTED GUSTY NORTH WINDS WARRANT A SNOW AND
BLOWING SNOW ADVY FOR JUDITH GAP. AS ARCTIC AIR PLUNGES WOULD
EXPECT A PERSISTENT AND STRONG NORTH WIND THROUGH THE FAVORED GAP.
SNOW AMOUNTS SHOULD REMAIN ON THE ORDER OF 1-2 INCHES OVER THE
REST OF OUR WESTERN PLAINS AS WE NEVER GET INTO A PERIOD OF
UPSLOPE.
REGARDING THE WINTER STORM WATCH WILL MAKE NO CHANGES AT THIS
TIME. HOWEVER...DEEP COLD ADVECTION/STRONG DESCENT WORKS ACROSS
OUR EASTERN PARTS QUICKLY BY MIDDAY TUESDAY...AS FOCUS OF SYNOPTIC
LIFT SHIFTS TO OUR NORTH...SO MAIN FOCUS OF THIS EVENT SHOULD BE
THE WINDS/WIND CHILLS RATHER THAN THE SNOW AMOUNTS. WILL CONTINUE
TO HIGHLIGHT THESE IN THE STATEMENT...AND LET DAY SHIFT TAKE
ANOTHER LOOK.
JKL
.LONG TERM...VALID FOR WED...THU...FRI...SAT...SUN...
UPPER LEVEL SYSTEM THAT IS BRINGING THE COLDEST AIR OF THE SEASON
TO THE AREA BEGINS TO MOVE EASTWARD ON WEDNESDAY YIELDING TO AN
UPPER LEVEL RIDGE BUILDING INTO THE PACNW. STILL COLD ON WEDNESDAY
BUT EXPECT MOSTLY DRY CONDITIONS WITH THURSDAY SEEING A WARM UP AS
SOME LEESIDE TROUGHING BEGINS TO DEVELOP. RIDGE BREAKS DOWN AND A
SHORTWAVE TRACKS INTO THE AREA THURSDAY NIGHT BUT THIS WAVE LOOKS
TO BE FILLING AS A RESULT OF MOVING THROUGH THE RIDGE. THIS MEANS
NOT A LOT OF PRECIPITATION SHOULD BE EXPECTED FROM THIS SYSTEM.
HOWEVER...GENERAL FLOW PATTERN THROUGH THE PERIOD IS NORTHERLY SO
EVEN PERIODS OF SOUTHWEST SURFACE WIND WOULD NOT YIELD TREMENDOUS
MODERATION BECAUSE OF COLD AIR ADVECTION AT 700 MB. THE WEEKEND
SHOWS ANOTHER RIDGE BUILDING OVER THE PACIFIC NORTHWEST BUT FLOW
ALOFT OVER SOUTHERN MONTANA SHOULD BE NORTHERLY...THUS REMAINING
FAIRLY COOL. DO NOT SEE A LOT OF PRECIPITATION POTENTIAL IN THE
PATTERN BUT ANY ARCTIC BOUNDARY THAT COMES DOWN DURING THIS PERIOD
COULD GENERATE A SHOT OF SNOW. BORSUM
&&
.AVIATION...
AREAS OF LOW CLOUDS ARE BANKED UP AGAINST THE FOOTHILLS AND
ADJACENT PLAINS WITH NORTHERLY WINDS CREATING UPSLOPE CONDITIONS.
LOWER ELEVATIONS WILL REMAIN VFR WHILE AREAS WEST AND SOUTH OF
BILLINGS WILL EXPERIENCE IFR CONDITIONS. A PUSH OF PRECIPITATION
INTO WESTERN AREAS THIS AFTERNOON WILL SPREAD EASTWARD THIS
EVENING. THIS WILL BRING A ROUND OF SNOW TO THE AREA AND
ASSOCIATED MVFR AND IFR CONDITIONS. BORSUM
