.SHORT TERM...TONIGHT THROUGH WEDNESDAY.

LARGE CLOSED UPPER LOW CONTINUES TO CIRCULATE OVER A GOOD PORTION OF
THE NRN PLAINS WITH THE TROF AXIS EXTENDING WELL INTO THE SRN
PLAINS. AT THE SFC...A 983 MB LOW IS CURRENTLY CENTERED OVER NRN
WI WITH A HIGH PRESSURE RIDGE AXIS BUILDING DOWN FROM ALBERTA INTO
CNTRL MT. VERY TIGHT PRESSURE GRADIENT IS IN PLACE AND HAS BEEN
PUSHING SFC WINDS TO NEAR ADVISORY CRITERIA TO OUR NORTH AND WEST.
850 MB WINDS OF 50+ KTS WL NOSE IN FROM THE NORTHWEST THIS EVENING
AND GIVEN GOOD MIXING AND MOMENTUM TRANSFER...WL GO AHEAD WITH A
WIND ADVISORY FOR MUCH OF THE NORTHERN HALF OF THE CWA FROM 00Z
MON- 00Z TUE. THE TIGHT GRADIENT AND STRONG 850MB PUSH WL CONTINUE
THRU THE DAY MONDAY AND SHOULD BEGIN TO RELAX SOME BY 00Z TUES.
LIGHT SNOW IS EXPECTED TO CONTINUE AROUND THE BACKSIDE OF LOW
PRESSURE SYSTEM IN FAIRLY BROAD DEFORMATION ZONE. STILL LOOKS LIKE
LESS THAN AN INCH OF ACCUMULATION. NOT EXPECTING VERY LOW
VISIBILITY RESTRICTIONS DUE TO THE LIGHT NATURE OF THE SNOW AND
LITTLE ACCUMULATIONS.

HAVE TAPERED SNOW OFF ON MONDAY AND CONTINUED SCT FLURRIES INTO
MONDAY EVENING AS SYSTEM CONTINUES TO PULL EAST. SFC HIGH PRESSURE
RIDGE MOVES INTO THE CWA EARLY TUESDAY. CLOUDS SHOULD SCOUR OUT OF
THE WESTERN COUNTIES BUT AM UNCERTAIN HOW MUCH CLEARING MAY OCCUR IN
THE EAST AS WE COULD KEEP A PESKY STRATUS DECK ACROSS THE AREA.

MID AND HIGH CLOUDS ARE FORECAST TO MOVE IN BY TUE NIGHT AS WAA TO
OUR SOUTH INCREASES. WEAK ISENTROPIC LIFT MAY HELP GENERATE A FEW
FLURRIES ACROSS THE CWA TUESDAY NIGHT. LOW LEVELS LOOK FAIRLY DRY AS
HIGH PRESSURE RIDGE CONTINUES TO RETREAT TO THE EAST. WL CONTINUE
SMALL CHANCE OF SNOW ON WEDNESDAY OUT AHEAD OF A SWRN US TROF DIGGING
ACROSS THE FOUR CORNERS REGION. BAROCLINIC ZONE WL STRETCH ACROSS
THE CWA AS ARCTIC HIGH PUSHES DOWN FROM CANADA.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY.

MADE RELATIVELY LARGE DOWNWARD REVISION TO TEMPERATURES IN WED NGT
THRU FRI NGT PDS. HIGHER CONFIDENCE THAN YDA IN SRN STREAM TROUGH
REMAINING TO OUR SOUTH ON THURSDAY WITH FORECAST AREA UNDER THE
EFFECTS OF NRN STREAM UPPER FLOW WITH COLD HIGH PRESSURE SETTLING
OVER AREA FRI/SAT.  VERY GOOD AGREEMENT BETWEEN 12Z OPERATIONAL
GFS...00Z ECMWF AND 00Z GFS ENSEMBLES IN THIS RESPECT.  IN FACT GFS
ENSEMBLE MEAN 850 MB TEMPS WERE EVEN COLDER THAN 12Z OPERATIONAL RUN
WHICH WAS COLD ENOUGH AS IT WAS. THUS FELT TEMPS SHOULD BE AT LEAST
AS COLD AS LATEST MEX GUIDANCE BASED ON THIS AND IN FACT THEY MAY
EVEN END UP COLDER. LEFT IN A SLIGHT CHC OF SNOW FAR S WED NGT IN
WEAK WARM ADVCTN PATTERN BEFORE HIGH PUSHES DOWN...OTHERWISE
EXTENDED FORECAST WAS DRY.  ALLOWED FOR A MODEST TEMPERATURE
MODERATION SAT/SUN... ESPECIALLY SUNDAY.
