.PREV DISCUSSION... /ISSUED 407 AM EST FRI FEB 20 2009/

SHORT TERM...(TONIGHT THROUGH SATURDAY NIGHT)...

LATENT WEAKENING LAKE EFFECT SNOW SHOWERS CONTINUE TO WIND DOWN OVER
NW PORTIONS OF THE CWA LEAVING THE APPROACHING STORM FOR TONIGHT
INTO SATURDAY AS THE MAIN FOCUS OF THE SHORT TERM FORECAST.  POTENT
UPR LEVEL TROF EVIDENT ON WV IMAGERY OVER ALBERTA POISED TO QUICKLY
DROP THROUGH THE UPPER PLAINS INTO THE GREAT LAKES WITH ASSOC SFC
LOW SET TO TRACK NE THROUGH OR NEAR THE CWA SATURDAY BRINING MORE
SNOW TO THE REGION.

00Z MODEL CYCLE HAS BROUGHT A MIXED BAG OF INFORMATION TO THE
PUZZLE.  WHILE THE GFS IS EERILY CONSISTENT WITH ITSELF AND ITS
TIGHTLY PACKED ENSEMBLE GUIDANCE THE NAM HAS TAKEN A SHIFT TO THE
NORTH WITH THE SFC LOW TRACK...DUE TO A MUCH DEEPER MID LEVEL
TROF/CLOSED LOW AND A DEEPER SFC LOW. DESPITE ITS RUN-TO-RUN
CONSISTENCY THE GFS AND ITS ENSEMBLE ARE THE ODD MEN OUT AS THE 00Z
ECMWF AND 03Z SREF EACH LEND SUPPORT TO THE NAM SOLUTION.
FURTHERMORE, A LAST SECOND GLANCE AT THE 06Z NAM FURTHERS THIS
TREND.  THIS HAS SERIOUS CONSEQUENCES TO POTENTIAL SNOWFALL
AMOUNTS AS THE SREF/NAM TRACK BRINGS A BRIEF BURST OF INTENSE
ISENTROPIC ASCENT FOLLOWED BY DRY SLOTTING FOR MORE OF THE CWA AS
DEFORMATION SNOWS JUST BRUSH WEST AND NORTH AREAS. FOR NOW...WILL
LET WATCH RIDE AS-IS WHILE ADJUSTING GRIDS CONSERVATIVELY IN THE
NORTHERLY DIRECTION MAINTAINING HEAVIEST SNOW AMOUNTS ALONG THE
MODEL AGGREGATE H85 LOW TRACK WHICH IS NEARLY VERTICALLY STACKED
WITH THE SFC LOW AND FAVORS THE NORTHERN TIER OF COUNTIES. THIS
STILL MATCHES UP WITH THE GOING WATCH WITH TYPICAL ACCUMULATIONS
APPROACHING 6 INCHES IN THE EXTREME NORTH. SHOULD A MORE SOUTHERLY
SFC LOW TRACK RE-EMERGE WITH THE COMING MODEL CYCLES...THE WATCH IS
ALSO WELL POSITIONED TO HANDLE THIS OUTCOME. SOUTH OF THE
WATCH...SNOW AMOUNTS PARED BACK MODESTLY AS MAIN EVENT EXPECTED TO
BE JUST THE QUICK ISENT ASCENT REGIME.

SOME LAKE ENHANCEMENT IS POSSIBLE ON THE BACK SIDE OF THE LOW LATE
ON SATURDAY PARTICULARLY IF A MORE SOUTHERLY LOW TRACK SIMILAR TO
THE GFS EVOLVES AS H85 TEMPS APPROACH -14C BY SAT AFTERNOON WHILE
WINDS TURN NW. THIS BEGINS TO BLEND INTO LAKE EFFECT DEVELOPING SAT
NIGHT AS DELTA T/S REACH THE UPPER TEENS WITH A SATURATED LAYER
BELOW INVERSION REACHING THROUGH THE ENTIRE GROWTH ZONE IN A
UNIDIRECTIONAL 20-25 KNOT NW WIND.

&&

LONG TERM...(SUNDAY THROUGH THURSDAY)...

DETERMINISTIC AND ENSEMBLE GUIDANCE CONTINUE TO SHOW  RIDGING OVER
THE CENTRAL PACIFIC BEING A DOMINANT CONTROLLING FACTOR OF THE UPPER
FLOW PATTERN THROUGH THE PERIOD.  THIS RIDGE WOULD POINT TO
TROUGHING SOMEWHERE NEAR THE WEST COAST OF THE CONUS WITH SPLIT FLOW
OVER MUCH OF THE COUNTRY. AS DESCRIBED BY THE DAY SHIFT
YESTERDAY...A REX BLOCK FEATURE OVER THE NE PACIFIC WOULD TEND TO
FAVOR THE NORTHERN STREAM DOMINATING THE SPLIT FLOW PATTERN.

ALSO...GUIDANCE INDICATES A STRENGTHENING VORTEX NEAR HUDSON BAY
THAT DEVELOPS IN RESPONSE TO DOWNSTREAM BLOCKING OVER GREENLAND.
THIS PROVIDES A SOURCE OF ANOMALOUSLY COLD AIR OVER CENTRAL CANADA
POISED TO MAKE A RUN AT US AT SOME POINT IN THE COMING WEEK.  WITH
NORTHERN STREAM DOMINANCE...BUT SOME SOUTHERN STREAM ENERGY...WE
COULD CERTAINLY BE IN FOR AN UNSETTLED PATTERN WITH SOME MORE
OUTBREAKS OF ARCTIC AIR.

FOR THE SPECIFICS...LEANED TOWARDS HPC/S PREFERENCE FOR THE ECMWF
BUT OVERALL...GUIDANCE IS IN DECENT AGREEMENT THROUGH THE PERIOD.

ON SUNDAY...LAKE EFFECT SNOWS ARE EXPECTED WITH T850 AROUND -15C AND
DEEP NORTHWEST FLOW. INVERSION HEIGHTS START THE DAY QUITE
HIGH...AROUND 700 HPA AND THE OMEGA MAX LINES UP NICELY WITH THE
DENDRITIC GROWTH ZONE...SO MEANINGFUL ACCUMS CERTAINLY LOOK POSSIBLE
AND HAVE UPPED POPS TO LIKELY OVER BERRIEN COUNTY WHICH APPEARS
QUITE LIKELY TO SEE AT LEAST SOME SNOW.  BUILDING HEIGHTS AND THE
NEARING OF SURFACE HIGH PRESSURE WILL HELP DROP INVERSION HEIGHTS
LATER IN THE DAY CAUSING THE CHANCES FOR ACCUMULATING SNOW DECREASE
HEADING TOWARDS EVENING.  WITH T925 AROUND -10C EXPECT HIGHS IN THE
MID 20S.

SUNDAY NIGHT WILL SEE THE LAKE EFFECT COME TO AN END AS WARM
ADVECTION ALOFT KICKS IN ALONG WITH SURFACE HIGH PRESSURE
CRESTING OVERHEAD.  CONTINUED TO UNDERCUT GUIDANCE LOWS IN AREAS
MOST LIKELY TO CLEAR...WITH LOWS AVERAGING AROUND 10F THROUGHOUT THE
CWA.  EXPECT THAT IF ANY ADJUSTMENTS TO THE LOWS ARE
NECESSARY...THEY WILL BE TO DROP TEMPS A FEW MORE DEGREES GIVEN
POSSIBLE FRESH SNOWPACK/LIGHT WINDS/DECREASING CLOUD COVER.

MONDAY AND TUESDAY WILL BE QUIET WITH THE SURFACE HIGH CRESTING
OVERHEAD MONDAY...THE H850 RIDGE CRESTING MONDAY NIGHT AND THEN DEEP
LAYER SOUTHWEST FLOW DEVELOPING BY TUESDAY.  T925 WILL STILL BE
AROUND -10C FOR MONDAY...BUT WITH MORE SUN EXPECT HIGHS 25-30.
MONDAY NIGHT COULD AGAIN BE COLD GIVEN LIGHT FLOW AND POTENTIAL NEW
SNOWPACK...WITH LOWS 10-15F.  FOR TUESDAY...T925 WILL HAVE RISEN TO
AROUND -3C YIELDING HIGHS IN THE MID 30S EAST AND UPPER 30S WEST.

THE WEDNESDAY-THURSDAY PERIOD LOOKS MORE UNSETTLED AS A WAVE IN THE
DEVELOPING ZONAL FLOW MOVES THROUGH THE REGION BRINGING WITH IT A
RELATIVELY WEAK COLD FRONT.  HAVE CONTINUED CHC POPS FOR WEDNESDAY
AND WITH T925 SUPPORTING HIGHS AROUND 40 EVEN WITH AMPLE CLOUD
COVER...EXPECT PTYPE TO BE RAIN.  BEHIND THE SYSTEM WEDNESDAY
NIGHT...THERE COULD STILL BE SOME LINGERING SHSN SO FOR THIS
REASON...AND THE FACT THAT TIMING OF THE WEDNESDAY SYSTEM MAY BE A
LITTLE OFF GIVEN THE STRONG FLOW...HAVE MAINTAINED CHC POPS.  A MORE
POTENT WAVE ENTERS THE PICTURE ON THURSDAY BUT MODELS DIVERGE ON THE
DETAILS BY THIS POINT WITH THE GFS HAVING A MUCH STRONGER NORTHERN
STREAM SHORT WAVE AND THE ECMWF A COMPACT WAVE RIDING EAST IN THE
ZONAL FLOW.  CHC POPS APPEAR PRUDENT GIVEN WHAT LOOKS LIKE AN
UNSETTLED PERIOD AND WITH TEMPS ALOFT RIGHT AROUND THE FREEZING
MARK...WILL INCLUDE BOTH SN AND RA AS PTYPES.
