402 PM EST SAT FEB 24 2007

.SHORT TERM...TONIGHT AND SUNDAY

12Z MODEL RUNS PERSIST IN BRINGING A ROBUST SURFACE LOW OUT OF THE
CENTRAL PLAINS...PUSHING THE TENACIOUS EASTERN LAKES REGION RIDGE
ON OUT. THIS LOW TO REACH THE NORTHERN ILLINOIS VICINITY BY SUNDAY
EVENING AS PER MODEL CONSENSUS...WHILE SLOWLY FILLING AS THE SYSTEM
OCCLUDES. AT 500 MB...SHARP SHORTWAVE RIDGE OVERHEAD TO BE NUDGED
EAST TONIGHT AS CLOSED PLAINS LOW ADVANCES INTO THE SOUTHWESTERN
LAKES REGION BY LATE SUNDAY.

MOISTURE TIME SECTIONS SHOW DEEP MOISTENING FROM SOUTHWEST TO
NORTHEAST TONIGHT BEHIND THE DEPARTING RIDGE. SOMEWHAT OF A DRY SLOT
ALOFT STILL PORTRAYED BY MODELS FOR SUNDAY BY MIDDAY INTO THE
AFTERNOON BUT PRIMARILY AFFECTING THE SOUTHERN HALF OF THE FORECAST
AREA.

12Z MODEL CONSENSUS SHOWS OCCASIONAL LOW TO MID LEVEL OMEGA ASCENT
AS HIGH AS 5 TO 10 UBAR/SEC THROUGH SUNDAY...MOST PARTICULARLY LATE
TONIGHT INTO SUNDAY AND ESPECIALLY AT AND ABOVE 700 MB. ALSO...THIS
OMEGA LIFT SEEN TO OCCASIONALLY OVERLAP THE FAVORABLE DENDRITIC SNOW
GROWTH REGION.

RATHER ROBUST 850 TO 500 MB AND 500 MB TO 300 MB QVECTOR CONVERGENCE
MOVING IN LATE TONIGHT...AND OVERHEAD MUCH OF SUNDAY. THE 500 MB TO
300 MB LAYER QVECTOR CONVERGENCE COUPLING AT TIMES WITH
FRONTOGENESIS LARGELY AT OR JUST ABOVE 700 MB. ALSO...OCCASIONAL
NEGATIVE EQUIVALENT POTENTIAL VORTICITY SEEN ABOVE THE
FRONTOGENETICAL LAYER. LOW LEVEL WIND CONVERGENCE ALSO ON THE
INCREASE SUNDAY...AND ACCOMPANIED BY SLIGHT 250 MB DIVERGENCE TO ADD
PRECIPITATION SUPPORT. THE 12Z GFS AND NAM 290K ISENTROPIC SURFACE
SHOW UP TO 5 UBAR/SEC ASCENT LATE TONIGHT AND SUNDAY...WITH
CONDENSATION PRESSURE DEFICITS LOWERING TONIGHT MAINLY LATE AT
NIGHT....ALSO SPECIFIC HUMIDITY BY SUNDAY SPORTING A FAIRLY JUICY 3
TO 5 G/KG.

MODEL SOUNDINGS DO SHOW POTENTIAL ICE NUCLEATION INTERRUPTION SUNDAY
MAINLY SOUTH HALF. ALSO IN THE SOUTH...THE MODEL SOUNDINGS CONTINUE
TO SUPPORT FREEZING RAIN OR SLEET...INCREASINGLY SOUTHWARD TO THE
OHIO BORDER. NEAR THE BORDER...TEMPERATURES MAY CLIMB TO A FEW
DEGREES ABOVE FREEZING DURING SUNDAY...ALLOWING A POTENTIAL PERIOD
OF RAIN.

AM GOING WITH HEADLINES FOR A SOMEWHAT LONG EVENT...INTO SUNDAY
NIGHT...FOR THE ENTIRE AREA. IN THE NORTH...WINTER STORM WARNINGS
FOR PRIMARILY SNOW TYPE AND LONGER SUPPORTING DYNAMICS WILL AID IN
BETTER SNOWFALL AMOUNTS...WITH BLOWING SNOW ALSO A GOOD BET THERE.
FARTHER TO THE SOUTH...WINTER WEATHER ADVISORIES ARE BEING ISSUED
FOR LESS SNOW BUT MORE OF A MIX...WITH EXPECTED SLEET ACCUMULATIONS OR
ICE BUILDUP NOT GENERALLY EXPECTED TO REACH WARNING THRESHOLDS.

&&

.LONG TERM...SUNDAY NIGHT THROUGH SATURDAY

THE 12Z MODEL SUITE FORECAST THE OCCLUDED SYSTEM TO MOVE INTO THE
VICINITY OF NORTHERN IL/SOUTHERN LAKE MICHIGAN BY MON MORNING.
LINGERING MID LEVEL DEFORMATION SNOW SHOULD BE ONGOING AT THE START
OF THE SUNDAY NIGHT PERIOD...ESPECIALLY NORTH OF THE I69 CORRIDOR.
THE PRECIPITATION WILL THEN DIMINISH IN INTENSITY HEADING INTO
MONDAY MORNING AS THE UPPER LEVEL SYSTEM BEGINS TO FILL IN AND THE
REMNANTS OF THE MID LEVEL DEFORMATION LIFT NORTH OF THE FORECAST
AREA. THE UPPER LOW AND ASSOCIATED SURFACE LOW WILL LINGER ACROSS
THE SOUTHERN GREAT LAKES REGION THROUGH TUESDAY AS A REX TYPE
BLOCKING PATTERN SETS UP WITH STRONG RIDGING PERSISTING OVER
NORTHERN ONTARIO. THE SYSTEM WILL CONTINUE TO WEAKEN THROUGHOUT
MONDAY AND TUESDAY. MODEL SOLUTIONS HOWEVER CONTINUE TO SHOW
LINGERING MOISTURE AT LEAST THROUGH 700MB WITH AMPLE LOW LEVEL
CONVERGENCE PERSISTING INTO TUESDAY. THIS WILL EQUATE TO CLOUDY
SKIES AND SCATTERED TO NUMEROUS SNOW SHOWERS ACROSS THE FORECAST
AREA. GIVEN THE WEAKENING TREND TO THE SYSTEM...EXPECTING ADDITIONAL
ACCUMULATIONS MONDAY INTO TUESDAY TO BE MINOR.

AN AMPLIFYING TROUGH OFF THE WEST COAST IS FORECAST TO BECOME PHASED
WITH A STRONG SUBTROPICAL JET TO THE WEST OF BAJA...LEADING TO
ANOTHER HIGHLY AMPLIFIED TROUGH OVER THE WESTERN CONUS AND STRONG
CENTRAL US SURFACE LOW BY MID WEAK. RIDGING AHEAD OF THIS SYSTEM
WILL ACT TO EJECT THE LINGERING UPPER TROUGH OVER THE SOUTHERN LAKES
REGION TO THE EAST BY WEDNESDAY. THE ASSOCIATED STORM SYSTEM TO
AFFECT THE CENTRAL US IS FORECAST TO BE FAIRLY SIMILAR TO THE
ONGOING STORM SYSTEM OVER THE PLAINS. ONE NOTABLE DIFFERENCE HOWEVER
IS A MUCH STRONGER UPPER LEVEL JET IN THE BASE OF THE TROUGH (140KT
FORECAST MIDWEEK COMPARED TO THE 110KTS OBSERVED THIS MORNING). THIS
SHOULD ALLOW THE LOW TO LIFT FARTHER NORTH THAN THE CURRENT SYSTEM
AFFECTING THE NATION. OF THE 12 AND 00Z MODEL SUITE...PREFERENCE
LIES WITH THE STRONGER EUROPEAN SOLUTION WHICH TAKES A VERY DEEP
SURFACE LOW INTO THE UPPER MISSISSIPPI VALLEY BY THE END OF THE
WEEK. THE GFS/CANADIAN/WRFHEMI SOLUTIONS ARE STILL SIMILAR TO THE
EUROPEAN. THE CURRENT MENTION OF RAIN AND SNOW LATE IN THE WEEK
LOOKS REASONABLE BASED ON THE 12Z GUIDANCE. THIS SYSTEM THURS INTO
FRI DOES HAVE THE POTENTIAL TO PRODUCE MORE FREEZING RAIN AND SLEET.
WILL AWAIT TO SEE HOW A COUPLE MORE MODEL RUNS HANDLE THE TIMING AND
TRACK OF THE LATE WEEK SYSTEM BEFORE MENTIONING FREEZING RAIN IN THE
FORECAST.
