ALTHOUGH WINDS WILL BE LIGHTER THAN TODAY, CONSIDERABLE SUNSHINE

.LONG TERM...

SUNDAY THROUGH FRIDAY

HIGHLY AMPLIFIED FLOW WILL BE THE NORM THROUGH THE PERIOD AS AN
EASTERN PAC TROUGH WILL SUPPORT SEVERAL DISTURBANCES INTO THE CONUS.
A PERTURBED HEIGHT PATTERN OVER THE GULF OF ALASKA WILL SUPPORT
EASTERN PAC TROUGH RELOADING WITH FLOW AMPLIFICATION EXPECTED
DOWNSTREAM INTO NOAM. FORECAST MODELS ARE IN GENERAL SYNOPTIC
SCALE AGREEMENT WITH PERHAPS THE GFS BEING TOO AGGRESSIVE WITH
EASTERN NOAM RIDGE SUPPRESSION BY MID NEXT WEEK PER IT/S SOLUTION OF
A CLOSED HEIGHT FIELD ON THE SOUTHERN PERIPHERY OF THE EASTERN PAC
TROUGH. PREFERENCE IS TOWARD THE ECMWF/GEM WHICH FITS PROGGED UPPER
FLOW/JET STRUCTURE OVER THE SOUTHERN PLAINS...AND ALSO IS IN LINE
WITH MEAN GEFS AND DGEX TRENDS. CERTAINLY LOOKS LIKE A ROLLER
COASTER RIDE PER THERMAL FIELDS IS IN STORE...WITH SEVERAL CHANCES
FOR PRECIP LOOMING. ALL INDICATIONS ARE TOWARD A GRADUAL SE TREND
PER AN ARCTIC AIRMASS DAY/S 7 AND BEYOND...WITH POSSIBLE
INTRODUCTION INTO THE NORTHERN PLAINS BY LATE DAY 7. MAIN CONCERN IN
THE PERIOD WILL BE MIXED PRECIP ON SUN...WITH SNOW CHANCES ON MONDAY.

SUN-MON...THE FIRST IN A SERIES OF POTENT UPPER LEVEL IMPULSES WILL
EJECT FROM THE SW CONUS...WITH HEIGHT ADJUSTMENT AND WAA ONGOING
INTO THE FA BY SUN MORNING. MAIN AREA OF LARGE SCALE ASCENT WILL
REMAIN WELL NORTH OF THE REGION...WITH A LINGERING LL DRY WEDGE
/EVIDENT IN BUFR DATA/ LIKELY FIGHTING AGAINST LL THETA-ADV
PROCESSES. THETA-E ADV IS CERTAINLY NOT IMPRESSIVE WITH STRONGER
FORCING SHIFTING NORTH OF THE AREA...BUT STILL EXPECT A PERIOD OF
MIXED PRECIP ACROSS THE NORTH...WITH A CHANCE SOUTH. FORECAST MODELS
HAVE CERTAINLY WAVERED ON THE TRACK OF THE LOW...WITH 12Z GUIDANCE
GENERALLY FAVORING A SFC LOW TRACK OVER THE FAR NORTH. PREFERENCE IS
FOR A NORTHERNER BIASED TRACK GIVEN SIG LOSS OF SNOW COVER/WEAK CAA
SURGE FRI-SAT/AND GENERAL SE FLOW THROUGH THE EVENT.
HENCE...HEAVIEST PRECIP AND ANY ASSOCIATED WINTER WEATHER IMPACTS
ARE LIKELY TO STAY NORTH OF THE FA. WARM NOSE TEMPS SURGE TO WELL
OVER 8C FA-WIDE...WITH PERHAPS THE NE SEEING A PERIOD OF ICING.
ADJUSTED PRECIP TYPE AND MAX T/S SUN TO REFLECT THIS. PHASING UPPER
WAVE WILL PUSH SLOWLY EAST SUN NIGHT INTO MON...WITH MID LEVEL DRY
SLOTTING LIKELY OVER THE FA SUN NIGHT. RETAINED LIKELY POP MENTION
NORTH...BUT IT IS QUITE POSSIBLE THAT APPRECIABLE PRECIP MAY RESIDE
WELL NORTH OF THE FA...WITH DRIZZLE LIKELY UNDER THE SFC LOW
NORTHERN AREAS. TROUGH SHIFTS SLOWLY SE MON...WITH COOLING PROFILES
SUPPORTING A CHANGE OVER TO SNOW NW-SE. ACCUMULATING SNOW WILL BE
POSSIBLE ON MONDAY ACROSS PORTIONS OF THE AREA...AND ANY ACCUMS WILL
HIGHLY DEPEND ON HOW QUICK PROFILES COOL AND HOW FAR NORTHWEST THE
ASSOCIATED LL DEFORMATION ZONE ENDS UP...AS THERMAL PROFILES ARE
QUITE WARM.

TUE-FRI...DRY WEATHER EXPECTED TUE-WED AS DEEP LAYER RIDGING IS
PROGGED. TEMPS WILL BE QUITE TRICKY GIVEN QUESTIONS ON SNOW COVER
FROM MON. TUE DOES LOOK MUCH COOLER GIVEN CAA SURGE AND LIGHT
MIXING...BUT SNOW COVER WILL CERTAINLY DICTATE MIXING HEIGHTS...WITH
MUCH WARMER CONDITIONS POSSIBLE GIVEN THE INCREASING SUN ANGLE. THE
SAME IS TRUE FOR WED AS AMPLE SUN COULD SUPPORT STRONG SUPER
ADIABATS. ANOTHER EJECTING IMPULSE IS EXPECTED BY THUR-FRI WITH DEEP
SOUTHERLY FLOW LIKELY TO SUPPORT WARM TEMPS IN THE PERIOD PRE-COLD
FRONTAL. PREFERRED TO TREND TOWARD HPC NUMBERS THUR WHICH SUPPORT
TEMPS INTO THE 40S...TO NEAR 50 SOUTH. WARMER READINGS ARE QUITE
POSSIBLE. OTHERWISE...RETAINED CHANCE POPS WITH A RAIN SNOW MIX
