A STRONG SHORT WAVE TROUGH AND ASSOCIATED MIDDLE AND UPPER-LEVEL
JETSTREAKS NOW OFF THE PACIFIC NW AND NRN CA COASTS WILL DIG SEWD
INTO THE GREAT BASIN AND LOWER CO VALLEY BY SUNDAY MORNING. DYNAMIC
FORCING FOR ASCENT AND RESULTANT STEEPENING MIDLEVEL LAPSE RATES
WILL SUPPORT WEAK CONVECTIVE INSTABILITY AND THE POTENTIAL FOR
LOW-TOPPED TSTM DEVELOPMENT ALONG SYSTEM TRACK TODAY INTO TONIGHT.

SURFACE COLD FRONT OVER THE CNTRL PENINSULA WILL CONTINUE SWD
TODAY...ENHANCING CONVECTIVE DEVELOPMENT THROUGH THE DIURNAL HEATING
CYCLE. WHILE AMBIENT WARM SECTOR IS WARM AND QUITE MOIST...12Z
OBSERVED SOUNDINGS AND FORECAST DATA SUGGEST THAT POOR MIDLEVEL
LAPSE RATES WILL LIMIT THE DEPTH OF DEVELOPING UPDRAFTS. ISOLATED
LIGHTNING WILL BE POSSIBLE WITH THE DEEPEST CONVECTIVE ELEMENTS THIS

SPC AC 271728

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1128 AM CST SAT NOV 27 2010

VALID 281200Z - 291200Z

...NO TSTM AREAS FORECAST...

...SYNOPSIS...
MID-UPPER LEVEL FLOW PATTERN IS EXPECTED TO BECOME MORE AMPLIFIED
ACROSS THE CONUS DURING DAY 2. A PACIFIC TROUGH MOVING INTO THE WRN
U.S. TODAY IS EXPECTED TO EVOLVE INTO A DEEPER FULL LATITUDE
LONGWAVE TROUGH ACROSS THE WRN HALF OF THE COUNTRY ON SUNDAY...
WHILE A LARGE DOWNSTREAM RIDGE BUILDS ACROSS THE ERN STATES. WITHIN
THE WRN TROUGH...A LEAD SHORTWAVE TROUGH SHOULD TRACK NEWD FROM THE
LOWER CO RIVER VALLEY TO THE NRN PLAINS...WHILE ADDITIONAL SHORTWAVE
ENERGY DIGS SEWD INTO THE BASE OF THE LONGWAVE TROUGH OVER THE SRN
ROCKIES/NRN MEXICO.

AT THE SURFACE...A COLD FRONT IS EXPECTED TO MOVE EWD ACROSS PARTS
OF THE NRN/CENTRAL PLAINS...WHILE A LARGE AREA OF HIGH PRESSURE OVER
THE ERN STATES SHIFTS SLOWLY TOWARD THE ATLANTIC SEABOARD.

...NWRN GULF COAST TO THE ARKLATEX...
LOW LEVEL MOISTURE RETURN IN ADVANCE OF THE PLAINS COLD FRONT IS
EXPECTED TO BE LIMITED TO THE NWRN GULF COAST REGION AND EVEN ACROSS
THIS AREA...THE QUALITY OF MOISTURE RETURN REMAINS UNCERTAIN. A
MORE SUBSTANTIAL MOISTURE SURGE /SURFACE DEWPOINTS IN THE MID-UPPER
60S/ SHOULD NOT OCCUR UNTIL LATE IN THE FORECAST PERIOD...
29/06-12Z...OR POSSIBLY NOT UNTIL AFTER THE START OF DAY 3. IN
ADDITION TO MODEL DIFFERENCES IN THE QUALITY/TIMING OF MOISTURE
RETURN...THERE ARE DIFFERENCES IN THE STRENGTH OF THE LOW LEVEL CAP
ACROSS THIS REGION. WEAK HEIGHT FALLS WITH THE APPROACH OF THE WRN
TROUGH COMBINED WITH INCREASING LOW LEVEL WAA AND ISENTROPIC ASCENT
ARE EXPECTED TO SUPPORT SHOWERS FROM THE NWRN GULF COAST TO THE
ARKLATEX LATE SUNDAY NIGHT/EARLY MONDAY MORNING. ALTHOUGH FORECAST
DIFFERENCES IN THE LOW-MID LEVEL THERMODYNAMICS PRECLUDE THE
INTRODUCTION OF A GENERAL TSTM AREA...THE OVERALL TSTM POTENTIAL MAY
RAMP UP FAIRLY QUICKLY AT THE START OF DAY 3 AS STRONGER FORCING
REACHES THIS REGION.

...S FL/KEYS...
SHOWERS WILL BE POSSIBLE ACROSS THIS AREA ON SUNDAY...THOUGH WEAK
MIDLEVEL FORCING FOR ASCENT AND WARM MIDLEVEL TEMPERATURES SHOULD
LIMIT TSTM DEVELOPMENT. ALTHOUGH A STRIKE OR TWO COULD OCCUR...
OVERALL COVERAGE IS EXPECTED TO REMAIN TOO LOW TO WARRANT THE
INCLUSION OF A GENERAL TSTM AREA.

NWS STORM PREDICTION CENTER NORMAN OK
0331 AM CST SAT NOV 27 2010

VALID 301200Z - 051200Z

...DISCUSSION...
GFS AND ECMWF BOTH CONTINUE TO DEPICT THE PROGRESSION OF A SURFACE
COLD FRONT ACROSS THE ERN U.S. DAY 4 /TUE 11-30/...AS A LARGE UPPER
TROUGH LIKEWISE CROSSES THIS REGION. THE BOUNDARY IS EXPECTED TO
REACH THE MIDDLE/SRN ATLANTIC COAST BY THE START OF DAY 5...AND THEN
CONTINUE PROGRESSING ACROSS NEW ENGLAND...THE WRN ATLANTIC...AND S
FL THROUGH THE DAY 5 PERIOD.

MODELS THEN DIVERGE AS THE NEXT UPPER SYSTEM APPROACHES THE WRN
CONUS DAY 6...WITH UNCERTAINTY PRECLUDING ANY FORECAST FOR
CONVECTIVE WEATHER FROM DAY 6 ONWARD.

THE FRONTAL PASSAGE ACROSS THE SERN U.S. DAY 4 SHOULD SUPPORT AN
ASSOCIATED ZONE OF SHOWERS AND PERHAPS EMBEDDED THUNDERSTORMS.
WHILE INSTABILITY SHOULD BE QUITE LIMITED...STRONG SHEAR EXPECTED TO
ACCOMPANY THIS SYSTEM SUGGESTS SOME SEVERE THREAT -- THOUGH NOT
SUFFICIENT TO WARRANT AN OUTLOOK AREA THIS FORECAST.

VALID 291200Z - 301200Z

...SYNOPSIS...
A LARGE UPPER TROUGH EXITING THE ROCKIES AND ENTERING THE PLAINS AT
THE START OF THE PERIOD IS FORECAST TO PROGRESS SLOWLY EWD THROUGH
THE PERIOD...BECOMING CENTERED OVER THE CENTRAL U.S. BY 30/12Z. AS
THIS TROUGH ADVANCES...AN ASSOCIATED SURFACE COLD FRONT WILL
LIKEWISE SHIFT EWD WITH TIME. WHILE MODELS DIFFER FAIRLY
SUBSTANTIALLY ON THE DEGREE OF EWD FRONTAL PROGRESS WITH TIME...IT
APPEARS THAT THE BOUNDARY SHOULD CROSS THE MS VALLEY BY THE END OF
THE PERIOD.

...CENTRAL GULF COAST REGION...
WHILE MODEL TIMING DIFFERENCES RAISE QUESTIONS WITH RESPECT TO
DEGREE AND LOCATION OF SEVERE POTENTIAL...WILL NONETHELESS INTRODUCE
5% SEVERE PROBABILITY ACROSS THE CENTRAL GULF COAST REGION FOR
MONDAY INTO EARLY TUESDAY AS GULF MOISTURE RETURNS NWD AHEAD OF THE
ADVANCING FRONT. WITH UPPER 60S DEWPOINTS STILL PROGGED BY MOST
DETERMINISTIC MODELS AND LATEST SREF RUN TO REACH COASTAL AREAS
PRIOR TO FRONTAL PASSAGE...MARGINALLY UNSTABLE AIRMASS WILL LIKELY
BE AVAILABLE. THUS...WITH CONVECTIVE DEVELOPMENT EXPECTED NEAR THE
FRONT AS IT SHIFTS INTO THE CENTRAL GULF COAST REGION...THIS
COMBINED WITH A FAVORABLY SHEARED ENVIRONMENT WILL SUPPORT AT LEAST
LIMITED SEVERE/TORNADO THREAT.

NWS STORM PREDICTION CENTER NORMAN OK
1157 PM CST FRI NOV 26 2010

VALID 281200Z - 291200Z

...NO TSTM AREAS FORECAST...

...SYNOPSIS...
A LARGE WRN U.S. UPPER TROUGH WILL PROGRESS EWD ACROSS THE
ROCKIES...AND BEGIN AFFECTING THE PLAINS STATES AS A DOWNSTREAM
RIDGE SHIFTS INTO THE ERN CONUS.

AT THE SURFACE...LOW PRESSURE OVER THE CENTRAL HIGH PLAINS EARLY IN
THE PERIOD IS FORECAST TO SHIFT NNEWD ACROSS THE MID MO VALLEY
REGION...WHILE A TRAILING COLD FRONT MOVES ACROSS PARTS OF KS/OK/TX
THROUGH THE END OF THE PERIOD.

WITH A LARGE AREA OF SURFACE HIGH PRESSURE TO REMAIN IN PLACE OVER
THE ERN HALF OF THE CONUS AND LITTLE MOISTURE RETURN NWD AHEAD OF
THE FRONT MOVING INTO THE PLAINS...THUNDERSTORMS ARE NOT ANTICIPATED
ACROSS THE CENTRAL CONUS. A FEW SHOWERS AND POSSIBLY AN ISOLATED
THUNDERSTORM MAY AFFECT S FL/THE KEYS...BUT THREAT APPEARS TOO LOW
TO WARRANT INCLUSION OF A 10% LINE. SIMILARLY...SCATTERED SHOWERS
ARE ALSO EXPECTED ACROSS PORTIONS OF THE WRN U.S. AS THE UPPER
TROUGH CROSSES THIS REGION...BUT INSTABILITY SHOULD PROVE
INSUFFICIENT FOR APPRECIABLE THUNDER THREAT.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1118 PM CST FRI NOV 26 2010

VALID 271200Z - 281200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
WHILE BLOCKING OVER THE ATLANTIC MAY SLOW EASTWARD PROGRESSION...
THE REMNANTS OF A DEEP CLOSED LOW AND ASSOCIATED LARGE-SCALE UPPER
TROUGHING ARE PROGGED TO BEGIN LIFTING OUT OF THE EASTERN U.S.
DURING THIS FORECAST PERIOD. MODELS INDICATE THAT THIS WILL OCCUR
AS UPPER RIDGING CONTINUES TO BUILD AND SHIFT EASTWARD THROUGH THE
CENTRAL STATES...AHEAD OF ANOTHER LARGE-SCALE TROUGH GRADUALLY
DEVELOPING ACROSS THE WEST.

WITHIN THIS LATTER FEATURE...A VIGOROUS SHORT WAVE IMPULSE APPEARS
LIKELY TO DIG INLAND ACROSS CALIFORNIA LATER TODAY AND TONIGHT.
GUIDANCE SUGGESTS THAT THIS WILL BE ACCOMPANIED BY STRONG MID-LEVEL
COOLING /WITH A 500 MB COLD CORE BELOW -30C/...WHICH MAY CONTRIBUTE
TO SUFFICIENT DESTABILIZATION FOR WEAK LOW TOPPED THUNDERSTORM
ACTIVITY ALONG THE PACIFIC NORTHWEST AND NORTHERN CALIFORNIA
COASTS...INTO THE SACRAMENTO VALLEY THIS AFTERNOON.

OTHERWISE...THE EVOLVING PATTERN APPEARS LIKELY TO MAINTAIN STABLE
CONDITIONS ACROSS MUCH OF THE NATION WITH GENERALLY NEGLIGIBLE
CONVECTIVE POTENTIAL. EVEN ALONG THE SURFACE FRONT EXPECTED TO
ADVANCE SOUTHWARD THROUGH THE REMAINDER OF THE FLORIDA PENINSULA...A
RELATIVELY WARM MID-LEVEL ENVIRONMENT SEEMS LIKELY TO SUPPRESS DEEP
CONVECTIVE DEVELOPMENT...AND THE RISK FOR THUNDERSTORM ACTIVITY OVER
INLAND AREAS...IN THE ABSENCE OF SUBSTANTIVE MID/UPPER FORCING FOR
UPWARD VERTICAL MOTION.

CONCERNING...HEAVY SNOW

VALID 270516Z - 270915Z

HEAVY SNOWFALL DEVELOPING WITHIN LAKE EFFECT BANDS NEAR THE ERN
SHORES OF LAKE ONTARIO AND LAKE ERIE IS FORECAST TO INCREASE IN
INTENSITY THROUGH THE MORNING. SNOWFALL RATES OF 2-3 IN/HR ARE
EXPECTED.

CURRENT SFC OBS/VWP DATA REVEAL STRONG/NEARLY UNIDIRECTIONAL
LOW-LEVEL WLY FLOW CONTRIBUTING TO A LONG FETCH OF MOISTURE OFF OF
LAKE ERIE AND ONTARIO...TO THE S OF AN UPPER CYCLONE PASSING THROUGH
ERN CANADA. LOCALIZED CONVERGENT FLOW HAS DEVELOPED IMMEDIATELY
DOWNSTREAM FROM THE ERN SHORES...RESULTING IN LOCALIZED SNOWBANDS
EVIDENT ON RADAR REFLECTIVITY. LOW-LEVEL LAPSE RATES ARE FORECAST TO
STEEPEN OVER THE NEXT SEVERAL HRS...AS A POOL OF COLDER MID-LEVEL
TEMPS /-18 TO -20 C AT 700 MB/ POSITIONED UPSTREAM WILL SHIFT INTO
THE REGION. PERSISTENT LOW-LEVEL CONVERGENCE COMBINED WITH AN
INCREASINGLY UNSTABLE THERMODYNAMIC PROFILE WILL CONTRIBUTE TO
HIGHER SNOWFALL RATES OVER THE NEXT SEVERAL HRS. FORECAST MODELS
INDICATE WIND FIELDS WILL VEER 10-20 DEG BY 12Z...WHICH MAY LEAD TO
A SLIGHT REPOSITIONING OF THE SNOWBANDS TO THE S.
