...NO SVR TSTM AREAS FORECAST...

WATER VAPOR IMAGERY SHOWS AN UPPER-LEVEL LOW OFF THE COAST OF NRN CA

SYNOPTIC REGIME WILL CONTINUE TO FAVOR SHOWER ACTIVITY AND BANDS OF
RAINFALL ACROSS MOST OF SRN AND CNTRL CA. A FEW THUNDERSTORMS WILL
BE POSSIBLE NEAR THE SRN AND CNTRL CA COASTS THIS EVENING DUE TO
STEEP MID-LEVEL LAPSE RATES AND STRONG LARGE-SCALE ASCENT.
HOWEVER...SFC TEMPS SHOULD BEGIN TO COOL EARLY THIS EVENING
RESULTING IN A GRADUAL DECREASE IN THUNDERSTORM POTENTIAL. ELSEWHERE
ACROSS THE CONUS...THUNDERSTORM ACTIVITY IS NOT EXPECTED THIS

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0133 PM CST MON FEB 16 2009

VALID 162000Z - 171200Z

...THERE IS A SLGT RISK OF SVR TSTMS THIS AFTN AND EARLY EVE ACROSS
THE L.A. BASIN AND ADJACENT SRN CA COASTAL AREAS....

THE MAIN MID-LEVEL CIRCULATION CENTER EMBEDDED WITHIN THE BROADER
SCALE UPPER TROUGH WEST OF PACIFIC COASTAL AREAS IS EXPECTED TO
REMAIN OFFSHORE OF NORTHERN CALIFORNIA THROUGH THE BALANCE OF THE
FORECAST PERIOD. BUT...IT APPEARS THAT A LOW AMPLITUDE WAVE...WITH
PERHAPS A COUPLE OF SMALLER SCALE PERTURBATIONS...IS NOW IN THE
PROCESS OF MIGRATING INLAND ACROSS SOUTHERN CALIFORNIA...
ACCOMPANIED BY A 70-90 KT 500 MB JET STREAK. AND...MODELS INDICATE
THAT MID-LEVEL FORCING FOR UPWARD VERTICAL ASSOCIATED WITH THIS
FEATURE WILL OVERSPREAD THE LOS ANGELES BASIN BETWEEN NOW AND EARLY
EVENING.

IT APPEARS THAT STRONGEST FORCING MAY COINCIDE WITH THE PEAK
AFTERNOON HEATING...ROUGHLY 22-00Z...WHEN MODEL FORECAST SOUNDINGS
INDICATE THAT A SHALLOW SURFACE-BASED STABLE LAYER MAY FINALLY
ERODE. SURFACE WARMING AND MOISTENING...COUPLED WITH MID-LEVEL
COOLING...MAY YIELD CAPE OF A FEW HUNDRED J/KG...EXTENDING THROUGH
THE FAVORABLE MIXED PHASE LAYER FOR CHARGE SEPARATION. A FEW LOW
TOPPED THUNDERSTORMS ARE POSSIBLE. WITH OROGRAPHICALLY BACKED NEAR
SURFACE FLOW CONTINUING TO SUPPORT SIZABLE CLOCKWISE CURVED
LOW-LEVEL HODOGRAPHS AND THE POTENTIAL FOR ROTATING UPDRAFTS...A
WINDOW OF OPPORTUNITY EXISTS FOR THE RISK OF TORNADOES...IN ADDITION
TO SOME HAIL AND GUSTY WINDS...LATE THIS AFTERNOON.

SWODY2
SPC AC 161727

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1127 AM CST MON FEB 16 2009

VALID 171200Z - 181200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
TO THE WEST OF A BLOCKING UPPER RIDGE NEAR THE CANADIAN
ROCKIES...THE NEXT IN A SERIES OF STRONG SHORT WAVE IMPULSES IS
ALREADY BEGINNING TO DIG SOUTH OF THE ALEUTIANS. MODELS INDICATE
THAT A CONTINUED SOUTHEASTWARD PROGRESSION OF THIS SYSTEM WILL FORCE
THE INCREASINGLY SHEARED REMNANTS OF THE CLOSED LOW...NOW NEAR THE
CALIFORNIA COAST...EASTWARD WITHIN THE PRIMARY BELT OF POLAR
WESTERLIES EXTENDING ACROSS THE CENTRAL/SOUTHERN TIER OF THE UNITED
STATES.

WHILE A CONSIDERABLE PORTION OF THE REMNANT CIRCULATION MAY LINGER
NEAR THE CENTRAL CALIFORNIA COAST THROUGH MUCH OF THE DAY
TUESDAY...AN INITIAL IMPULSE EMANATING FROM THE SYSTEM IS PROGGED TO
ACCELERATE THROUGH A CONFLUENT REGIME ACROSS THE GREAT BASIN AND
CENTRAL ROCKIES INTO THE CENTRAL PLAINS. THEREAFTER...THE LATTER
FEATURE IS EXPECTED TO TURN EAST NORTHEASTWARD THROUGH THE MIDDLE
MISSISSIPPI AND LOWER OHIO VALLEYS...CONTRIBUTING TO THE ONSET OF
MID-LEVEL HEIGHT FALLS ACROSS MUCH OF THE CENTRAL U.S...AHEAD OF A
COLD UPPER VORTEX DIGGING SOUTH OF THE CENTRAL CANADIAN PROVINCES.

ALTHOUGH SOME VARIABILITY EXISTS AMONG THE MODELS CONCERNING THE
DETAILS...GUIDANCE GENERALLY INDICATES THAT THE EVOLVING UPPER
PATTERN WILL BE ACCOMPANIED BY SIGNIFICANT LOW-LEVEL CYCLOGENESIS TO
THE LEE OF THE CENTRAL ROCKIES. AND...AS THE DEEPENING SURFACE LOW
MIGRATES FROM THE CENTRAL PLAINS THROUGH THE MIDDLE MISSISSIPPI
VALLEY...A SUBSTANTIVE RETURN FLOW OF MOISTURE APPEARS LIKELY TO
COMMENCE OFF THE WESTERN GULF OF MEXICO.

...SERN PLAINS THRU LWR MS/OH AND TENNESSEE VALLEYS...
SREF INDICATES THAT THIS MOISTURE RETURN WILL PROBABLY BE
CHARACTERIZED BY PRECIPITABLE WATER ON THE ORDER OF 1.25 INCHES...
WITH A HIGH PROBABILITY OF UPPER 50S/LOWER 60S SURFACE DEW POINTS
SURGING BACK THROUGH MUCH OF THE LOWER MISSISSIPPI VALLEY BY 12Z
WEDNESDAY. THIS IS EXPECTED...HOWEVER...BENEATH A WARMING LOWER/
MID TROPOSPHERIC ENVIRONMENT ASSOCIATED WITH SHORT WAVE RIDING...
WHICH SHOULD SUPPRESS THE DEVELOPMENT OF THUNDERSTORMS THROUGH MUCH
OF THE DAY...AND COULD INHIBIT ACTIVITY THROUGH MUCH OF THE
REMAINDER OF THE PERIOD.

GUIDANCE IS SUGGESTIVE THAT STORMS COULD INITIATE WITHIN A ZONE OF
ENHANCED LOWER/MID-LEVEL WARM ADVECTION ON THE NORTHEASTERN EDGE OF
THE CAP BY THE 18/03-06Z TIME FRAME...IN THE GENERAL VICINITY OF
WESTERN KENTUCKY/TENNESSEE INTO NORTHERN MISSISSIPPI...BEFORE
SPREADING EASTWARD TOWARD THE UPPER TENNESSEE VALLEY. IT IS
POSSIBLE...IN THE PRESENCE OF FAVORABLE DEEP LAYER SHEAR...THAT
SUFFICIENTLY STEEP MID-LEVEL LAPSE RATES AND CAPE MAY DEVELOP FOR
THE RISK FOR HAIL IN STRONGER STORMS...PARTICULARLY AS THE NIGHT
WEARS ON.

CONTINUING LOW-LEVEL MOISTENING AND ASCENT ASSOCIATED WITH LOW-LEVEL
WARM ADVECTION IS EXPECTED TO EVENTUALLY YIELD CAPE OF 500-1000
J/KG...BASED NEAR OR JUST ABOVE THE SURFACE...ACROSS MUCH OF THE
LOWER MISSISSIPPI VALLEY BY 09-12Z WEDNESDAY MORNING. WHILE
MID/UPPER FORCING FOR UPWARD VERTICAL MOTION MAY BE WEAK TO THE
SOUTH OF AN INTENSIFYING /IN EXCESS OF 90 KTS/ 500 MB JET STREAK
ACROSS THE SOUTH CENTRAL PLAINS/OZARK PLATEAU...THERE IS A SIGNAL
AMONG THE MODELS THAT THE CAPPING LAYER MAY BECOME SUPPRESSED ENOUGH
FOR SCATTERED STORM DEVELOPMENT BY THE END OF THE PERIOD. IF THIS
OCCURS...THE ENVIRONMENT ALONG AN AXIS FROM NEAR OR JUST SOUTH OF
THE ARKLATEX INTO NORTHERN MISSISSIPPI/ WESTERN TENNESSEE WILL
BECOME INCREASINGLY FAVORABLE FOR BOUNDARY LAYER...OR NEAR BOUNDARY
LAYER...BASED STORMS. IN THE PRESENCE OF SIZABLE CLOCKWISE CURVED
LOW-LEVEL HODOGRAPHS AND STRONG DEEP LAYER SHEAR...SUPERCELLS ARE
POSSIBLE...PERHAPS WITH A RISK FOR TORNADOES...IN ADDITION TO
HAIL/GUSTY WINDS.

AREAS AFFECTED...WRN PARTS OF THE LOS ANGELES BASIN SWD ALONG THE

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 161651Z - 161815Z

THE POTENTIAL FOR ISOLATED SEVERE STORMS CAPABLE OF SOME
HAIL...GUSTY WINDS AND PERHAPS A BRIEF TORNADO APPEARS TO BE
INCREASING ACROSS THE DISCUSSION AREA. THIS THREAT IS FORECAST TO
CONTINUE INTO THIS AFTERNOON. CURRENTLY...A WW IS NOT ANTICIPATED.

LATEST MESOSCALE ANALYSIS INDICATES THAT LARGE-SCALE UPPER-LEVEL
PATTERN HAS SUPPORTED THE DEVELOPMENT OF A LOW-LEVEL CONVERGENCE
ZONE EXTENDING GENERALLY W-E FROM N OF CATALINA ISLAND EWD TO NEAR
RAL. TO THE S OF THIS BOUNDARY WINDS HAVE MAINTAINED A SELY
DIRECTION...WHEREAS TO THE N WINDS BACK TO ENELY. LOCAL RADAR
IMAGERY SUGGESTS THAT CONVERGENCE AND DEEPER-LAYER VERTICAL
VORTICITY IS BEING ENHANCED ALONG THIS BOUNDARY NEAR THE COAST BY AN
APPARENT MESOSCALE VORTICITY MAXIMUM CURRENTLY LIFTING NEWD INTO THE
LOS ANGELES METROPOLITAN AREA.

DESPITE THE VERY MARGINAL INSTABILITY...THIS ZONE OF CONVERGENCE HAS
ENHANCED ONGOING CONVECTIVE DEVELOPMENT OVER PORTIONS OF LOS ANGELES
AND NWRN ORANGE COUNTIES TO JUST E OF CATALINA ISLAND. LOCAL VWPS
CONTINUE TO INDICATE RATHER STRONG LOW-LEVEL SHEAR /25-40 KT/ ALONG
AND TO THE S OF THIS CONVERGENCE ZONE...SUGGESTING THE POTENTIAL FOR
EMBEDDED ROTATING CONVECTIVE ELEMENTS CAPABLE OF A BRIEF TORNADO IN
ADDITION TO SOME HAIL AND GUSTY WINDS.

FARTHER S...RADAR IMAGERY SHOWS INTENSIFYING CONVECTION ALONG
FRONTAL BAND TO THE W/SW OF SAN WITH EXTRAPOLATION TAKING THIS
ACTIVITY ONSHORE TO THE N OF SAN BETWEEN 1800-1830Z. HERE TOO...THE
POTENTIAL WILL EXIST FOR HAIL...LOCALLY STRONG WIND GUSTS AND
PERHAPS A BRIEF TORNADO ALONG THE IMMEDIATE COAST. ANY POTENTIAL
FOR A MORE SIGNIFICANT/ORGANIZED SEVERE WEATHER EPISODE IS EXPECTED
TO BE LIMITED BY THE VERY MARGINAL CONVECTIVE INSTABILITY.

VALID 161630Z - 171200Z

...THERE IS A SLGT RISK OF SVR TSTMS SRN CA COASTAL VALLEYS...

STRONG JET MAX THAT HAS ROTATED AROUND COLD LOW OFF NRN CA COAST
WILL BE APPROACHING SRN CA COAST THIS AFTN. VERY STRONG LOW/MID
LEVEL SHEAR PROFILES ARE CURRENTLY IN PLACE COASTAL SRN
CA...ENHANCED BY FORCED TERRAIN BACKING IN THE BOUNDARY LAYER.

THE VERY LIMITED INSTABILITY INLAND HAS INHIBITED DEVELOPMENT OF
MUCH IN THE WAY OF CONVECTION THUS FAR. HOWEVER AS DEWPOINTS RISE A
LITTLE THIS AFTERNOON COASTAL AREAS AND UPPER LEVEL COLD ADVECTION
ASSOCIATED WITH APPROACHING JET MAX STEEPENS LAPSE RATES TO GREATER
THAN 7C/KM...SBCAPE OF A COUPLE HUNDRED J/KG COULD DEVELOP COASTAL
AREAS.

THE MORE FRONTAL TYPE BAND OF PCPN NOW MOVING EWD ACROSS LA BASIN
EVEN WITH ONLY SHALLOW CONVECTION HAS HAD BEEN CHARACTERIZED BY LOW
LEVEL SHEAR COUPLETS OVER THE WATER WHERE BOUNDARY LAYER
MOISTURE/INSTABILITY IS A LITTLE GREATER. ADDITIONAL POST-FRONTAL
MORE CONVECTIVE BANDS/ELEMENTS SHOULD MOVE ONSHORE THRU THE
AFTERNOON WITH A LITTLE GREATER THREAT OF WATERSPOUTS AND
FUNNELS/BRIEF TORNADO INLAND COASTAL AREAS...ASSOCIATED WITH
POSSIBLE MINI SUPERCELL DEVELOPMENT.

BOUNDARY LAYER WINDS SHOULD GRADUALLY VEER BY LATE AFTERNOON AS THE
UPPER JET MAX MOVES ACROSS SRN CA...RELAXING THE SHEAR AND THREAT OF
SEVERE STORMS ALTHOUGH SOME HAIL CAN BE EXPECTED WITH ANY GOOD
UPDRAFT THRU THE DAY GIVEN THE COLD AIR ALOFT AND STEEP LAPSE RATES.

...SYNOPSIS...
CLOSED LOW OFF THE NRN CA CST WILL REDEVELOP SE TOWARD SFO THIS
PERIOD AS DOWNSTREAM RIDGE PROGRESSES FROM THE SRN RCKYS/HI PLNS TO
THE OZARKS/WRN GULF CST. ONSHORE FLOW WILL STRENGTHEN AND DEEPEN
ALONG THE SRN CA CST TODAY AS VORT MAX NOW NEAR 34N/125W MOVES ENE
INTO S CNTRL CA BY EVE.

...CNTRL/SRN CA...
LEAD COLD FRONT ASSOCIATED WITH OFFSHORE LOW HAS ALREADY MOVED
INLAND ACROSS PART OF THE CNTRL VLY AND IS NEARING THE LAX AREA IN
SRN CA. THIS FEATURE WILL BE FOLLOWED BY SECONDARY FRONTAL ZONE
MORE CLOSELY ASSOCIATED WITH AFOREMENTIONED UPR VORT. LOW TO MID LVL
LAPSE RATES SHOULD SUBSTANTIALLY STEEPEN ACROSS CNTRL AND SRN CA
LATER TODAY IN RESPONSE TO MID LVL COOLING WITH UPR VORT AND
FAVORABLY-TIMED SFC HEATING. COUPLED WITH INCREASED ASCENT AHEAD OF
VORT AND FOCUSED UPLIFT NEAR SECONDARY FRONT...EXPECT CONSIDERABLE
COVERAGE OF SHOWERS/TSTMS BY AFTN FROM THE L.A. BASIN NWD INTO MUCH
OF CNTRL CA.

LIFT SHOULD BE MAXIMIZED IN LAX AREA THIS AFTN AS THE EXIT REGION OF
A 80+ KT MID LVL JET APPROACHES THE SRN CA CST...ENHANCING DEEP
SHEAR. COMBINATION OF INCREASING SHEAR AND DESTABILIZATION WITH LOW
FREEZING LVLS SHOULD SUPPORT STORMS WITH HAIL...ESPECIALLY NEAR THE
CST AND PERHAPS IN SRN/CNTRL PARTS OF THE CNTRL VLY. IN ADDITION...
TOPOGRAPHICALLY-INFLUENCED 40+ KT LLJ IN THE L.A. BASIN AND...TO A
LESSER EXTENT IN THE CNTRL VLY...LIKELY WILL EXIST TO ENHANCE LOW
LVL SHEAR WITH ANY SUSTAINED STORMS THAT DO FORM. THUS...POTENTIAL
WILL EXIST FOR ISOLD TORNADOES AND/OR WATERSPOUTS. THE STORMS
SHOULD WEAKEN AS UPR VORT CONTINUES INLAND AND BOUNDARY LAYER
DIURNALLY COOLS LATER TODAY/TONIGHT.

TROUGH IN THE EAST BY DAY 4...AND CONTINUE INTO AT LEAST DAY 6 OR 7
WHEN UNCERTAINTY BEGINS TO INCREASE. OVERALL SEVERE POTENTIAL WILL
BE LOW WITH THIS PATTERN WHICH WILL MAINTAIN OFFSHORE FLOW OVER THE

VALID 181200Z - 191200Z

...THERE IS A SLGT RISK OF SVR TSTMS OVER PORTIONS OF THE SERN
STATES...

...SYNOPSIS...

MODEL CONSENSUS IS THAT SRN BRANCH UPPER JET WILL ADVANCE INTO THE
LOWER MS...TN AND OH VALLEYS WED WHERE IT WILL INTENSIFY AS IT
MERGES WITH AMPLIFYING NRN STREAM. SUBSEQUENT CONSOLIDATION AND
AMPLIFICATION OF THE TROUGH WILL CONTINUE OVER THE ERN STATES WED
NIGHT. SURFACE LOW TRACK WILL REMAIN TIED TO STRONGER FORCING WITHIN
UPPER JET EXIT REGION. THIS FEATURE WILL LIFT NE THROUGH THE OH
VALLEY DURING THE DAY. TRAILING COLD FRONT WILL SWEEP EWD THROUGH
THE OH VALLEY AND SERN STATES.

...SERN STATES...

DEGREE OF SEVERE WEATHER THREAT REMAINS CONTINGENT ON AMOUNT OF
INSTABILITY THAT CAN DEVELOP IN WARM SECTOR. DEEPER GULF FRONTAL
INTRUSION WILL OCCUR MONDAY OVER THE CNTRL AND ERN GULF AS AREA OF
SURFACE HIGH PRESSURE ADVANCES THROUGH THE SERN STATES. EFFECTS OF
THE COLD ADVECTION WILL BE MUCH LESS OVER A PORTION OF THE SWRN GULF
WHERE DEWPOINTS WILL REMAIN IN THE UPPER 60S. BY WEDNESDAY AN AXIS
OF PARTIALLY MODIFIED GULF AIR WILL ADVECT NWD THROUGH THE LOWER MS
VALLEY AND A PORTION OF THE SERN STATES ALONG A STRONG SWLY LOW
LEVEL JET ASSOCIATED WITH THE EWD MIGRATING CYCLONE. ELEVATED STORMS
WILL BE ONGOING OVER A PORTION OF THE SERN U.S. AND OH VALLEY WITHIN
ZONE OF STRONG ISENTROPIC ASCENT. THE STORMS WILL SHIFT EAST DURING
THE DAY...BUT IN THEIR WAKE...WIDESPREAD CLOUDS WILL LIKELY PERSIST
OVER MUCH OF WARM SECTOR WHICH WILL TEND TO LIMIT INSTABILITY.

CLUSTERS OF STORMS MAY REDEVELOP ALONG AND EAST OF ADVANCING FRONT
WITHIN ZONE OF HEIGHT FALLS AND LOW LEVEL CONFLUENT FLOW REGIME FROM
THE LOWER MS VALLEY INTO PARTS OF THE SERN STATES. ACTIVITY WILL BE
EMBEDDED WITHIN VERY STRONG KINEMATIC PROFILES WHICH WOULD SUPPORT
AN ORGANIZED SEVERE THREAT INCLUDING POTENTIAL FOR SUPERCELLS AND
BOWING STRUCTURES WITH ANY SURFACE BASED DEEP CONVECTION. POTENTIAL
FOR A MARGINAL THERMODYNAMIC ENVIRONMENT COULD STILL POSE A LIMITING
FACTOR FOR A HIGHER END SEVERE EVENT.

...SRN PORTIONS OF THE OH VALLEY...

COLDER AIR ALOFT AND PLUME OF STEEPER MID LEVEL LAPSE RATES WILL
ATTEND THE UPPER JET EXIT REGION THROUGH SRN PARTS OF THE OH
VALLEY...AND THIS COULD COMPENSATE FOR MORE LIMITED LOW LEVEL
MOISTURE IN THIS AREA. STRONG AGEOSTROPHIC FORCING ATTENDING THE
UPPER JET WILL LIKELY CONTRIBUTE TO REDEVELOPMENT OF CONVECTION
SOUTH AND EAST OF SURFACE LOW TRACK. PRIMARY UNCERTAINTY AT THIS
TIME IS HOW MUCH THE BOUNDARY LAYER CAN DESTABILIZE IN WAKE OF
MORNING CONVECTION GIVEN POTENTIAL FOR LOW CLOUDS TO PERSIST. STRONG
VERTICAL SHEAR AND STEEP LAPSE RATES IN THIS REGION WOULD SUPPORT
ORGANIZED SEVERE STORMS. HOWEVER...DUE TO THE CONDITIONAL NATURE OF
THE THREAT ONLY 5% SEVERE PROBABILITIES WILL BE ADDED AT THIS
TIME...BUT AN CATEGORICAL RISK MIGHT BE NEEDED FOR A PORTION OF THIS
REGION IN LATER OUTLOOKS.

VALID 171200Z - 181200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...

PROGRESSIVE UPPER PATTERN WILL PERSIST OVER THE U.S. TUESDAY. THE
PRIMARY FEATURE OF INTEREST REMAINS A STRONG UPPER JET THAT WILL
EJECT FROM BASE OF UPPER LOW NOW SITUATED OFF THE CA COAST. THIS
FEATURE WILL REACH THE SRN PLAINS TUESDAY EVENING AND MID-LOWER MS
VALLEY TUESDAY NIGHT. CYCLOGENESIS WILL COMMENCE OVER THE CNTRL
PLAINS DURING THE DAY AS THE UPPER JET CROSSES THE ROCKIES. THE LOW
WILL DEVELOP EWD THROUGH KS WITHIN UPPER JET EXIT REGION OVERNIGHT
WHILE ATTENDANT COLD FRONT ACCELERATES SEWD THROUGH THE CNTRL AND
SRN PLAINS. FARTHER SOUTH...A WARM FRONT WILL ADVANCE NWD THROUGH
ERN TX AND THE LOWER MS VALLEY.

...ERN TX THROUGH THE LOWER MS AND TN VALLEY REGIONS...

SLY LOW LEVEL JET WILL STRENGTHEN FROM ERN TX INTO THE LOWER-MID MS
VALLEY AS LEE CYCLONE DEEPENS WITHIN UPPER JET EXIT REGION. THE LOW
LEVEL JET WILL CONTRIBUTE TO NWD TRANSPORT OF PARTIALLY MODIFIED
GULF AIR THROUGH TX...THE LOWER MS VALLEY AND WRN PARTS OF THE TN
VALLEY. STRONG WLY FLOW ALOFT WILL ADVECT STEEPER MID-LEVEL LAPSE
RATES EWD THROUGH THIS REGION ABOVE THE RETURNING MOIST AXIS. THESE
PROCESSES WILL RESULT IN MARGINAL ELEVATED INSTABILITY. ISENTROPIC
LIFT AND THETA-E ADVECTION ABOVE A STABLE SURFACE LAYER ASSOCIATED
WITH THE STRONG SWLY LOW LEVEL JET WILL LIKELY BECOME SUFFICIENT TO
SUPPORT THE DEVELOPMENT OF ELEVATED THUNDERSTORMS OVERNIGHT. STORMS
APPEAR MOST PROBABLE FROM THE LOWER MS VALLEY EWD THROUGH THE TN
VALLEY REGION WHERE DEEPER ASCENT AND COOLER MID LEVEL TEMPERATURES
WILL EXIST. THREAT OF ISOLATED HAIL MAY ACCOMPANY THE STRONGER
UPDRAFTS...ESPECIALLY ALONG ERN PERIPHERY OF THE EWD ADVANCING EML
WHERE LAPSE RATES WILL BE STEEPER.

HAVE INCLUDED A PORTION OF ERN TX IN A CATEGORICAL GENERAL
THUNDERSTORM OUTLOOK AND 5% HAIL PROBABILITIES...BUT THUNDERSTORM
PROSPECTS IN THIS REGION ARE HIGHLY CONDITIONAL. IT STILL APPEARS
MUCH OF ERN TX MIGHT REMAIN CAPPED TO DEEPER CONVECTION AS WARMER
850-700 MB TEMPERATURES ACCOMPANYING THE EML OVERSPREADS THE MOIST
AXIS.

...CA...

SCATTERED CONVECTION AND ISOLATED THUNDERSTORMS WILL REMAIN LIKELY
ACROSS PARTS OF CNTRL AND NRN CA IN ASSOCIATION WITH UPPER LOW WHERE
COLD TEMPERATURES ALOFT WILL CONTRIBUTE TO STEEP MID LEVEL LAPSE
RATES. SURFACE LOW OFFSHORE AND LOCAL TERRAIN EFFECTS WILL MAINTAIN
SELY LOW LEVEL FLOW IN THE SAN JOAQUIN AND SACRAMENTO VALLEY
AREA...WHICH WILL CONTRIBUTE TO VEERING LOW-LEVEL WIND PROFILES.
BEST CHANCE FOR SURFACE HEATING APPEARS TO BE OVER A PORTION OF THE
SAN JOAQUIN VALLEY. ISOLATED STORMS MAY BECOME CAPABLE OF PRODUCING
MAINLY SMALL TO MARGINALLY SEVERE HAIL IF SUFFICIENT INSTABILITY
DEVELOPS DURING THE DAY.

...SRN CA...
AN UPPER-LEVEL LOW OFF THE COAST OF NRN CA WILL MOVE SLOWLY SEWD
TODAY. PLENTIFUL LARGE-SCALE ASCENT SOUTHEAST OF THE LOW AND COLD
AIR ALOFT IN THE CORE OF THE SYSTEM WILL PROVIDE SUPPORT FOR
ISOLATED THUNDERSTORMS TODAY FROM THE CNTRL CA COAST AND SRN
SACRAMENTO VALLEY SSEWD TO THE LA BASIN. LIFT SHOULD BE MAXIMIZED IN
LA BASIN THIS AFTERNOON AS THE EXIT REGION OF A MID-LEVEL JET ROUNDS
THE BASE OF THE TROUGH AND MOVES OVER SRN CA. FORECAST SOUNDINGS
ACROSS THE LA BASIN THIS AFTERNOON SHOW STRONG VERTICAL SHEAR
ASSOCIATED WITH THE MID-LEVEL JET. THIS ALONG WITH THE COLD AIR
ALOFT MAY BE ENOUGH FOR A HAIL THREAT WITH THUNDERSTORMS THAT
DEVELOP LATE THIS MORNING THROUGH THE AFTERNOON WHEN SFC TEMPS WILL
BE A BIT WARMER. IN ADDITION...THE MODELS MOVE A 40 TO 50 KT
LOW-LEVEL JET SSEWD FROM THE CNTRL CA COAST SEWD INTO THE LA BASIN
TODAY. THIS ALONG WITH OROGRAPHIC EFFECTS FROM THE SURROUNDING
MOUNTAIN RANGES IN THE LA BASIN WILL LOCALLY ENHANCE LOW-LEVEL SHEAR
SUPPORTING A MARGINAL TORNADO THREAT WITH LOW-TOPPED THUNDERSTORMS
THAT INITIATE LATE THIS MORNING OR EARLY THIS AFTERNOON.
