DAY 1 CONVECTIVE OUTLOOK

VALID 270100Z - 271200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM IL TO NERN TX...

...MID MS VALLEY TO NERN TX...

WELL DEFINED UPPER VORT MAX IS SHIFTING EAST ALONG THE MN/IA BORDER
WITH TRAILING SHORTWAVE TROUGH EXTENDING SWD ALONG THE KS/MO BORDER.
LARGE SCALE ASCENT REMAINS FOCUSED PRIMARILY WITHIN WARM ADVECTION
ZONE ALONG/NORTH OF RETREATING WARM FRONT WHERE EXPANDING
PRECIPITATION SHIELD IS SPREADING ACROSS THE GREAT LAKES. ALTHOUGH
ISOLATED THUNDERSTORMS ARE EMBEDDED WITHIN THIS COOLER
PRECIPITATION...STRONGEST CONVECTIVE UPDRAFTS ARE FOCUSED ALONG
ADVANCING COLD FRONT FROM WCNTRL IL...SWWD INTO NERN OK. THIS TREND
SHOULD CONTINUE THROUGH THE NIGHT AS MORE MEANINGFUL INSTABILITY
EXISTS SOUTH OF I-70 OVER MO...PARTICULARLY SWRN MO INTO SERN OK/WRN
AR. THUNDERSTORMS FROM SGF TO FSM ARE INTENSIFYING WITHIN THIS
HIGHER ZONE OF INSTABILITY AND STRONG DEEP LAYER SHEAR. 00Z
SOUNDING FROM SGF DEPICTS STEEP LAPSE RATE ENVIRONMENT...7-7.5
C/KM...WITH ENOUGH BUOYANCY FOR ROBUST UPDRAFTS...MUCAPE ROUGHLY
1500 J/KG. ALTHOUGH STRONG CONVERGENCE ALONG THE COLD FRONT WILL
ENHANCE LINEAR DEVELOPMENT...STORM MODE REMAINS SOMEWHAT DISCRETE
ACROSS THIS REGION SUGGESTING SUPERCELLS ARE POSSIBLE FOR THE NEXT
FEW HOURS AT LEAST. WITH TIME CONVECTION SHOULD DEVELOP SWD ALONG
WIND SHIFT OVER SERN OK INTO PORTIONS OF NERN TX. A BROKEN SQUALL
LINE WITH EMBEDDED SUPERCELLS SHOULD THEN PROGRESS ACROSS MO/AR INTO
SRN IL LATER THIS EVENING INTO THE OVERNIGHT HOURS WITH LARGE HAIL
AND DAMAGING WINDS. ISOLATED TORNADOES CAN NOT BE RULED OUT WITH
SUPERCELL STRUCTURES OVER SRN MO INTO AR...ESPECIALLY THIS EVENING
BEFORE CONVECTIVE MODE BECOME A BIT MORE LINEAR IN NATURE.

COMPLEX AND OCCASIONALLY OVERLAPPING MESOSCALE WINTER PRECIP
SCENARIO WILL MOVE GENERALLY EWD ACROSS DISCUSSION AREA THROUGH 18Z
CHARACTERIZED PRIMARILY BY THESE REGIMES...

1. HEAVY SNOW GENERALLY N OF I-90 FROM ERN PORTIONS ND/SD LINE
ACROSS NERN SD...WRN/CENTRAL MN AND EVENTUALLY NW WI. GENERAL RATES
1-2 INCHES/HOUR...UPWARD TO 3 INCHES/HOUR IN BANDED SNOWFALL MAXIMA
-- ARE EXPECTED. MOST PROLONGED AREA OF HEAVY SNOW IS FCST TO SHIFT

ELEVATED CONVEYOR OF STRONGEST LARGE-SCALE ASCENT -- JUXTAPOSING LOW
LEVEL WAA AND MIDLEVEL DPVA AHEAD OF EJECTING WRN SD SHORTWAVE

THIS REGIME PER RUC CROSS-SECTION ANALYSIS AND PLANAR ISENTROPIC
ASCENT PROGS ON 288-300K SURFACES...WITH IDEAL DENDRITIC GROWTH
ZONES INCLUDED IN CONVEYOR OF STRONGEST LIFT.

2. MIXED PHASE TRANSITION WILL OCCUR ACROSS PORTIONS SERN SD...NERN

RAIN AT .05-.25 INCH/HOUR LIQUID EQUIVALENT WITHIN SRN PORTION OF
NEWD-RETREATING AREA OF 1-2 INCH/HOUR SNOWS. MOISTURE
ADVECTION/TRANSPORT IN WAA CONVEYOR WILL LEAD TO SLGT COOLING AND
NEAR-SATURATION OF WEDGE OF SUPERFREEZNG AIR ABOVE SFC THAT WILL
REMAIN WARM ENOUGH TO SUPPORT MIXED PRECIP TYPE. 12Z SFC ANALYSIS
SHOWED WAVY 32 F ISOTHERM JUST N OF I-80 IN IA THEN NWWD TO NEAR
ONL. SLGT/LOCALIZED NWD MOVEMENT IS POSSIBLE...THOUGH STG PRESSURE
FALLS AND RELATED NELY BACKING OF SFC WINDS N OF FREEZING LINE WILL

3. TSTMS PRODUCING HIGHLY LOCALIZED BUT SHORT-LIVED SLEET/FREEZING
RAIN RATES TO .25-.75 INCH/HOUR -- ALONG WITH HAIL UP TO NEAR SVR

SPC AC 261231

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0631 AM CST THU FEB 26 2009

VALID 261300Z - 271200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM PARTS OF THE MID MO/MID MS
RIVER VALLEY INTO THE MID SOUTH/AR/SERN OK...

...MID MO/MID MS RIVER VALLEYS INTO THE MID SOUTH/AR/SERN OK...
FAST MOVING...LOW-AMPLITUDE SHORTWAVE TROUGH WILL CONTINUE EWD
ACROSS THE CENTRAL PLAINS THIS AFTERNOON AND THE MID/UPPER MS RIVER
VALLEY LATER TONIGHT. ASSOCIATED SURFACE LOW DEVELOPING OVER WRN KS
EARLY THIS MORNING WILL LIKEWISE TRAVERSE ENEWD INTO THE IL/MO/IA
TRI-STATE REGION BY EARLY THIS EVENING...BEFORE LIFTING NEWD ACROSS
SRN LOWER MI OVERNIGHT. EARLY MORNING SURFACE ANALYSES INDICATED
COMPLEX SETUP WITH ARCTIC FRONT ESTABLISHED FROM THE NRN GREAT LAKES
INTO THE NRN HIGH PLAINS...AND A STATIONARY FRONT ERODING FROM THE
ERN GREAT LAKES TOWARDS LOW CENTER OVER NWRN KS. IN ADDITION...WARM
FRONT ALONG LEADING EDGE OF RETURNING GULF MOISTURE IS BECOMING
BETTER DEFINED ACROSS NRN KS INTO THE MID SOUTH. EXPECT WARM FRONT
WILL CONSOLIDATE/BECOME BETTER DEFINED THROUGH THE DAY FROM NRN IL
INTO ERN IA/NWRN MO...WITH STRONG SURFACE COLD FRONT CONTINUING SEWD
IN WAKE OF LOW CENTER THROUGH THE PERIOD.

SEVERE THREAT WILL LIKELY EVOLVE IN TWO MODES/AREAS DURING THE
PERIOD. THE FIRST OF WHICH IS ALREADY UNFOLDING OVER ERN NEB INTO
WRN-SRN IA/NERN KS/NWRN MO WHERE STRONG LOW LEVEL WAA IS LIFTING
PARCELS TO LFC/S BENEATH VERY STEEP MID LEVEL LAPSE RATES. 12Z
SOUNDINGS FROM OAX/SGF/TOP ALL INDICATE 500+ MUCAPE AND 35+ KT
EFFECTIVE SHEAR. ALTHOUGH ACTIVITY WILL REMAIN ROOTED WELL ABOVE
STABLE SURFACE...EVEN WITHIN DEVELOPING WARM SECTOR...VERY STEEP
LAPSE RATES AND 40-50 KT EFFECTIVE SHEAR WILL SUPPORT LARGE HAIL AND
ELEVATED SUPERCELLS ACROSS THIS REGION BEGINNING LATER THIS MORNING
AND CONTINUING ENEWD THROUGH MUCH OF THE DAY. FORECAST SOUNDINGS
INDICATE THIS ACTIVITY WILL LIKELY REMAIN ELEVATED AS IT DEVELOPS
ENEWD ACROSS THE MID MS RIVER VALLEY TODAY. HOWEVER...SHEAR WILL
REMAIN QUITE STRONG AND TRACK OF SURFACE LOW INTO NRN IL SUGGESTS
SURFACE-BASED THREAT WILL HAVE TO BE CLOSELY MONITORED THROUGH THE
DAY ALONG AND SOUTHEAST OF THE LOW.

SECOND AREA OF SEVERE THUNDERSTORMS IS EXPECTED TO DEVELOP ALONG THE
COLD FRONT FROM PORTIONS OF S-CENTRAL/SERN MO OR SRN IL INTO SERN OK
LATER THIS EVENING/OVERNIGHT. FORECAST SOUNDINGS MAINTAIN CAPPING
ALONG THE FRONT FOR MUCH OF THE DAYLIGHT HOURS...ALTHOUGH LOW
PROBABILITIES FOR SEVERE THUNDERSTORMS REMAIN WARRANTED OVER ERN KS
INTO NERN OK/SWRN MO IN CASE CAP DOES BREAK DURING THE DAY. MORE
LIKELY SCENARIO...WHICH IS SUPPORTED BY ALL THE OPERATIONAL
MODELS...IS FOR CAP TO WEAKEN ALONG FRONT AS IT INTERACTS WITH
RICHER GULF MOISTURE AND DEEP ASCENT BEGINS TO OVERSPREAD IT TOWARDS
06Z. BY THIS TIME...FRONT SHOULD EXTEND FROM SRN IL INTO SERN OK.
THIS ACTIVITY WILL HAVE THREAT OF NOT ONLY LARGE HAIL...BUT ALSO
SOME RISK OF WIND DAMAGE AND/OR ISOLATED TORNADOES AS STORMS ROOT IN
OR VERY NEAR THE BOUNDARY LAYER AND SHIFT SEWD ACROSS THE MID SOUTH
OVERNIGHT. ALTHOUGH STORMS NEAR AND WEST OF THE MID SOUTH MAY
REMAIN SEVERE INTO THE DAY 2 FORECAST PERIOD...SEVERE THREAT IS
EXPECTED TO DIMINISH WITH EWD EXTENT AS STORMS OVERSPREAD MORE OF
THE OH RIVER VALLEY AND CENTRAL KY/MIDDLE TN INTO EARLY FRIDAY
MORNING.

NWS STORM PREDICTION CENTER NORMAN OK

VALID 281200Z - 011200Z

...THERE IS A SLGT RISK OF SVR TSTMS OVER MUCH OF THE SOUTHEASTERN
U.S. SATURDAY AND SATURDAY NIGHT...

...SYNOPSIS...
MID/UPPER LEVEL LOW AND ASSOCIATED SHORTWAVE TROUGH OVER THE PAC NW
THURSDAY MORNING WILL MAINTAIN CONSIDERABLE AMPLITUDE AS IT DIGS
ACROSS THE CENTRAL PLAINS FRIDAY AND INTO THE MID SOUTH/LOWER MS
RIVER VALLEY SATURDAY. THIS SYSTEM WILL THEN TAKE ON A NEUTRAL OR
SLIGHT NEGATIVE TILT SATURDAY NIGHT/SUNDAY OVER THE SOUTHEASTERN
U.S. NAM...GFS AND ECMWF ARE IN SIMILAR AGREEMENT WITH THIS
SYSTEM...AND ALL DEVELOP A SURFACE LOW OVER CENTRAL AL BY SATURDAY
MORNING. LOW THEN TRACKS E-NEWD ALONG LIKELY WEDGE FRONT ACROSS
NRN/CENTRAL GA AND INTO WRN/CENTRAL SC DURING THE AFTERNOON...BEFORE
MOVING OFFSHORE SC/NC SATURDAY EVENING. STRENGTH OF SYSTEM
GENERATES LARGE MID LEVEL HEIGHT FALLS AND ENHANCED WIND FIELDS
ACROSS THE SOUTHEAST...WITH H5 SPEED MAX OF 80-100 KT ALONG BACK END
OF DIGGING TROUGH AND 50+ KT WLY MID LEVEL FLOW OVERSPREADING THE
WARM SECTOR.

SOME UNCERTAINTIES REMAIN /WHICH ARE COMMON WITH COOL SEASON SEVERE
WEATHER EVENTS 3+ DAYS OUT/ REGARDING QUALITY OF BOUNDARY LAYER
MOISTURE...EXTENT OF LOW CLOUDS/PRECIPITATION PRECEEDING SYSTEM AND
OVERALL TIMING. HOWEVER...MODELS ARE BEGINNING TO FAVOR POTENTIAL
FOR AN OUTBREAK OF SEVERE THUNDERSTORMS...INCLUDING TORNADOES...
SATURDAY INTO SATURDAY NIGHT OVER A LARGE PORTION OF THE
SOUTHEAST...AND HAVE BEEFED UP PROBABILITIES ACCORDINGLY.

EXPECT ONGOING STRONG/SEVERE ACTIVITY AT BEGINNING OF THE PERIOD
WHICH TO TRANSLATE QUICKLY EWD NEAR THE SURFACE LOW/COLD FRONT
ACROSS GA AND INTO SC THROUGH THE DAY. ACTIVITY WILL ALSO LIKELY
INTENSIFY NEAR AND AHEAD OF THE FRONT INTO SRN GA/NRN FL AS BOUNDARY
LAYER DESTABILIZES BY THE EARLY TO MID AFTERNOON. THREAT SHOULD
MANIFEST ITSELF AS BOTH FAST MOVING BOW SEGMENTS AND ISOLATED
TORNADIC SUPERCELLS.
