THE CHANCE FOR ISOLATED LARGE HAIL AND STRONG WIND GUSTS...AS WELL
AS VERY HEAVY RAIN...WILL CONTINUE FROM TSTMS ERUPTING OVER THE
HIGHER TERRAIN TO THE NORTH AND EAST OF THE LA BASIN LATE THIS
AFTERNOON. ISOLATED NATURE OF THE SEVERE WEATHER THREAT PRECLUDES A
WATCH AT THIS TIME.

A PLUME OF HIGH PW AIR BEING WRAPPED NWWD INTO/AROUND THE NERN
QUADRANT OF LARGE SCALE UPPER LOW OFF THE CA COAST HAS COINCIDED
WITH STRONG DIFFERENTIAL HEATING AND MESOSCALE ASCENT ACROSS THE
MOUNTAINS OF SRN CA TO SUPPORT STRONG TO ISOLATED SEVERE TSTM
DEVELOPMENT THIS AFTERNOON. RECENT RADAR TRENDS SUGGEST THAT SOME OF
THE MORE INTENSE CELLS ARE ANCHORED TO TERRAIN AND MAY PERSIST GIVEN
CONTINUING LOW LEVEL CONVERGENCE AND UPSLOPE FLOW NORTH AND EAST OF
LA AND SAN BERNARDINO. MLCAPE AROUND 1000 J/KG FEEDING INTO THIS
AREA IS MORE THAN ADEQUATE TO SUPPORT A CONTINUATION OF SCATTERED
STRONG STORM UPDRAFTS. MAIN LIMITATION FOR A GREATER SEVERE WEATHER
THREAT APPEARS TO BE LACK OF DEEP-LAYER SHEAR. MID LEVEL FLOW WITHIN
THE ERN SEMI-CIRCLE OF UPPER LOW CIRCULATION IS EXPECTED TO REMAIN
QUITE WEAK. HOWEVER...COLDER MID LEVEL TEMPERATURES AOB -12C
ASSOCIATED WITH THIS SYSTEM SHOULD CONTRIBUTE TO A SLIGHTLY GREATER
CHANCE FOR HAIL WITH A FEW OF THE STORMS. WEAK PROPAGATION AND
TERRAIN INFLUENCES ALSO SUGGEST THAT LOCALLY VERY HEAVY RAIN CAN BE
EXPECTED WITH THIS CONVECTION INTO THE EVENING.

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 102205Z - 110030Z

A COUPLE OF SEVERE HAIL AND/OR SEVERE WIND EVENTS WILL BE POSSIBLE
INTO THE EVENING HOURS IN A GENERALLY FOCUSED REGION OF SERN AZ.
GIVEN LIMITED AREAL EXTENT OF THIS THREAT...AND SOME UNCERTAINTY
REGARDING OVERALL DURATION/LONGEVITY...A WATCH IS NOT ANTICIPATED AT
THIS TIME.

RAPID AND ROBUST TSTM DEVELOPMENT HAS OCCURRED WITHIN THE LAST HOUR
OR SO ACROSS SRN PINAL AND WRN COCHISE COUNTIES OF ERN AZ AS STRONG
HEATING HAS ELIMINATED CONVECTIVE INHIBITION. TERRAIN INFLUENCES AND
APPROACH OF A LOW AMPLITUDE SHORT WAVE TROUGH EMANATING FROM THE
LARGER CLOSED LOW OFF THE COAST OF SRN CA ARE ALSO CONTRIBUTING TO
AN ENHANCEMENT IN BOTH MESOSCALE AND SYNOPTIC SCALE ASCENT ACROSS
THE REGION. A VERY UNSTABLE AIR MASS /MLCAPE TO 2000 J PER KG/
SHOULD CONTINUE TO FUEL A FEW INTENSE STORM UPDRAFTS. DEEP-LAYER
SHEAR IS SOMEWHAT MARGINAL FOR GREATER STORM ORGANIZATION GIVEN MID
LEVEL FLOW AOB 20KT. WHILE THIS SHOULD KEEP MOST ACTIVITY IN
MULTICELLULAR REALM...STRONGER SWLY FLOW EXISTS NEAR ANVIL LEVEL AND
IS EVIDENT IN MODEL DATA AND SUPPORTED BY RECENT VSBL SATL IMAGERY.
NOT ONLY WILL THIS ALLOW FOR AN EFFECTIVE EXHAUST MECHANISM FOR SOME
OF THE MORE INTENSE STORMS...BUT EFFECTIVE SHEAR IN THESE CASES
COULD BRIEFLY RESULT IN SUPERCELLULAR STRUCTURE AND ENHANCED
WIND/HAIL POTENTIAL.

BOTH THE LARGE HAIL AND DOWNBURST WIND THREAT WILL LIKELY BE
GREATEST OVER THE NEXT HOUR OR SO BEFORE STORM INTERACTIONS AND
INCREASE IN STORM COVERAGE ACT TO OVERTURN THE AIR MASS AND BEGIN TO
RESULT IN AN INCREASE IN INHIBITION.

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 102153Z - 102330Z

A FEW THUNDERSTORMS COULD PRODUCE GUSTY WINDS INTO THE EARLY EVENING
HOURS. A WW IS NOT NEEDED.

LATE AFTERNOON SFC MESOANALYSIS REVEALS A FEW FEATURES OVER PARTS OF
CNTRL/SOUTH FL THAT WILL CONTINUE TO FOCUS CONVECTION INTO THE EARLY
EVENING HOURS:

1. THE BAROCLINIC CIRCULATION IN ASSOCIATION WITH A REMNANT/STALLED
FRONTAL ZONE -- MARKING A PRONOUNCED SFC DEWPOINT GRADIENT -- DRAPED
FROM NEAR DAYTONA BEACH TO SW OF OCALA...
2. A SUBTLE CONFLUENCE AXIS LYING FROM NEAR MELBOURNE TO SARASOTA
AND FARTHER SW INTO THE OFFSHORE WATERS OF THE ERN GULF...EVIDENT IN
THE MOTION OF CLOUD ELEMENTS PER RECENT VISIBLE SATELLITE IMAGES...
3. THE EAST COAST SEA BREEZE BOUNDARY /AROUND 1.5-KM DEEP PER MIAMI
VWP DATA/ EXTENDING FROM NEAR MELBOURNE TO THE ERN PARTS OF LAKE
OKEECHOBEE TO WELL WSW OF MIAMI...AND
4. THE WEST COAST SEA BREEZE BOUNDARY EXTENDING FROM ENE OF SARASOTA
TO ENE OF FORT MYERS TO WELL WSW OF MIAMI.

AS THE WEST AND EAST COAST SEA BREEZE BOUNDARIES CONTINUE
PROPAGATING INLAND...THE MAINTENANCE OF SFC CONVERGENCE AMIDST
MLCAPE VALUES OF 1500-2500 J/KG WILL PROMOTE REGENERATIVE CONVECTION
OVER PRIMARILY INTERIOR SECTIONS OF THE CNTRL/SRN FL PENINSULA.
CONVERGENCE WILL BE AUGMENTED INVOF THE CONFLUENCE AXIS...WHERE
CONVECTIVE ACTIVITY MAY BE LOCALLY ENHANCED. HOWEVER...WITH ONLY 11
KT OF 0-6-KM SHEAR PER MIAMI VWP...PULSE CONVECTION WILL BE THE
PREDOMINATE MODE. MODESTLY INCREASED DEEP-LAYER SHEAR INVOF THE
REMNANT FRONT COULD PROMOTE MULTICELLULAR CONVECTION FARTHER NORTH
IN CNTRL FL. WITH PW VALUES OF 1.90-2.25 INCHES PER GPS
DATA...WATER-LOADING PROCESSES COULD SUPPORT GUSTY OUTFLOW WINDS AS
STORMS COLLAPSE. HOWEVER...THE ABSENCE OF STRONGER VERTICAL WIND
SHEAR WILL LIMIT THE OVERALL CONVECTIVE ORGANIZATION. STORMS SHOULD
BEGIN WEAKENING BY 00Z AS DIABATIC COOLING COMMENCES.

EXPECT WIDELY SCATTERED TSTMS WITH SOME CHANCE FOR ISOLATED HAIL TO
AROUND 1 INCH IN DIAMETER TO PERSIST INTO THE EVENING FROM PARTS OF
NRN AZ INTO WRN SECTIONS OF NM. A WATCH DOES NOT APPEAR LIKELY GIVEN
ISOLATED NATURE OF THE LARGE HAIL THREAT.

BROADLY DIFFLUENT MID AND UPPER LEVEL FLOW FIELD EXISTS ON THE ERN
FLANK OF LARGE UPPER LOW SPINNING OFF THE COAST OF SRN CA. LARGE
SCALE ASCENT ASSOCIATED WITH DPVA AHEAD OF THE LOW...COUPLED WITH
DIURNAL DESTABILIZATION...SHOULD RESULT IN A GRADUAL INCREASE IN
SCATTERED ROBUST CONVECTION IN AN ARC FROM NW YAVAPAI COUNTY IN AZ
TO ERN CATRON AND MCKINLEY COUNTIES IN WRN NM. MOISTENING IN THE LOW
TO MID LEVELS AND MODEST MID LEVEL LAPSE RATES AROUND 7.5 C/KM PER
LATEST OBJECTIVE DATA WERE SUPPORTING MLCAPE OF 800-1100 J/KG ACROSS
THESES AREAS. WITH WEAK LOW LEVEL NLY/NELY SURFACE LOW TOPPED BY THE
SW FLOW ALOFT...EFFECTIVE SHEAR VALUES ARE SUGGESTIVE OF A KINEMATIC
REGIME THAT SHOULD SUPPORT MARGINAL SUPERCELL STRUCTURES FROM A FEW
OF THE STRONGER STORM UPDRAFTS. SPC HAIL MODEL OUTPUT FROM LATEST
FORECAST SOUNDINGS INDICATES HAIL SIZE OF 1 TO 1.5 INCHES WILL BE
POSSIBLE IN THE MORE INTENSE CORES. LIMITED DEEP-LAYER FLOW AND
SOMEWHAT COOLER BOUNDARY LAYER PRECLUDE MUCH OF A DAMAGING WIND
THREAT AND...WHEN COMBINED WITH THE SPARSE NATURE OF THE LARGE HAIL
THREAT...SUGGEST THAT A WATCH IS NOT LIKELY.

...NO SVR TSTM AREAS FORECAST...

ONLY MINOR ADJUSTMENTS TO THE 5% SEVERE LINE FOR MARGINAL

TWO WEAK BUT PERSISTENT UPPER LOWS CONTINUE TO AFFECT THE CONUS
TODAY. ONE LOW OVER THE MID MS VALLEY WILL POSE A RISK OF SCATTERED
SHOWERS AND THUNDERSTORMS FROM PARTS OF KS/OK INTO THE UPPER OH
VALLEY AND MID ATLANTIC STATES. NO SEVERE WEATHER IS ANTICIPATED
ALONG THIS CORRIDOR.

...WEST...
A SECOND UPPER LOW IS OVER CA. WATER VAPOR IMAGERY SHOWS A SERIES
OF MINOR SHORTWAVE TROUGHS ROTATING AROUND THE LOW...WHICH WILL
AFFECT THE SOUTHWEST STATES THIS AFTERNOON AND TONIGHT. AN AXIS OF
SCATTERED THUNDERSTORMS HAS BEEN OCCURRING THIS MORNING ROUGHLY FROM
SBA TO LAS. ALONG AND SOUTH OF THESE STORMS...STRONG HEATING AND
COOL TEMPERATURES ALOFT WILL YIELD RELATIVELY STEEP LAPSE RATES AND
MODERATE INSTABILITY. WEAK ASCENT AHEAD OF THE APPROACHING SYSTEMS
MAY RESULT IN SCATTERED THUNDERSTORMS OVER THE MOUNTAINS AND DESERTS
OF SOUTHERN CA AND SOUTHERN AZ LATER TODAY. VERTICAL SHEAR IS
MARGINAL...BUT ORGANIZED MULTICELL STRUCTURES ARE POSSIBLE WITH HAIL

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
THE MID-UPPER LEVEL TROUGH OVER THE OH/MS VALLEY REGION WILL DRIFT
VERY SLOWLY SEWD AS IT BEGINS TO EVOLVE INTO MORE OF AN OPEN WAVE IN
RESPONSE TO HEIGHT FALLS WITHIN THE POLAR JET OVER ONTARIO.
RESIDUAL LOW-LEVEL MOISTURE AND EMBEDDED SPEED MAXIMA ROTATING
AROUND THE LOW WILL PROMOTE SCATTERED THUNDERSTORM DEVELOPMENT THIS
AFTERNOON FROM ERN KS/NE OK NEWD TO THE OH VALLEY.

A SEPARATE CLOSED LOW OVER SRN CA WILL REMAIN QUASI-STATIONARY
THROUGH THE PERIOD. PW VALUES OF 1-1.25 INCHES AND ASCENT
DOWNSTREAM FROM THE SRN CA LOW WILL MAINTAIN A RISK FOR
THUNDERSTORMS THROUGH TONIGHT FROM INTERIOR SRN CA TO SRN NV AND AZ.
INSTABILITY AND DEEP-LAYER VERTICAL SHEAR WILL BE SUFFICIENT FOR
ORGANIZED MULTICELL CLUSTERS CAPABLE OF PRODUCING MARGINALLY SEVERE
HAIL AND STRONG DOWNBURST WINDS NEAR THE MIDLEVEL COLD CORE IN
CA...AND ALONG/S OF THE RIM IN AZ.

TROUGH -- NOW EVIDENT IN MOISTURE CHANNEL IMAGERY OVER NERN PAC S OF
AK...SHOULD MOVE IN CURVING PATH FROM SRN PORTIONS SK/MB ACROSS NRN
ONT AND LS BY 13/12Z. MEANWHILE...PERSISTENT/CUT-OFF CYCLONE SHOULD
MEANDER ERRATICALLY OVER CENTRAL/SRN CA COASTAL AREA...WHILE SLOWLY
FILLING.

AT SFC...CYCLONE ASSOCIATED WITH NRN-STREAM TROUGH SHOULD CROSS NERN
ND/NRN MN REGION EARLY IN PERIOD...PIVOTING EWD ACROSS NRN
WI/LS/UPPER MI REGION TO NERN ONT BY END OF PERIOD. SREF AND
OPERATIONAL MODELS STILL DIFFER WITHIN TEMPORAL/SPATIAL WINDOW OF
4-6 HOURS AND UP TO ABOUT 200 NM ON TIMING/TRACK OF SFC LOW.
TRAILING COLD FRONT WILL MOVE SEWD OVER NRN PLAINS EARLY IN
PERIOD...REACHING SRN MN AND NRN/CENTRAL NEB BY 13/00Z. WARM FRONT
WILL EXTEND FROM LOW EWD ACROSS LS OR ADJOINING UPPER MI DURING
AFTERNOON/EVENING...BEFORE LIFTING NWD INTO ONT. BY 13/12Z...COLD
FRONT SHOULD REACH LOWER MI...NRN IL...NRN MO AND CENTRAL/SRN KS.
REMNANT FRONTAL ZONE WILL LINGER OVER PORTIONS NRN/CENTRAL FL
THROUGH MUCH OF DAY.

...UPPER MS VALLEY TO LS/LM...
SCATTERED TSTMS MAY DEVELOP NEAR SFC LOW AND ADJOINING FRONTAL
SEGMENTS DURING AFTERNOON...WITH POTENTIAL FOR AT LEAST ISOLATED SVR
HAIL/GUSTS. LEADING EDGE OF STRONGEST MID-UPPER
ASCENT/DESTABILIZATION SHOULD BE NEARLY COLLOCATED WITH RELATIVE
MAXIMA IN LOW-LEVEL CONVERGENCE ACCOMPANYING SFC LOW AND NEARBY
COLD-FRONTAL SEGMENT. THIS REGIME WILL IMPINGE UPON AT LEAST MRGLLY
FAVORABLE AND DIABATICALLY HEATED BOUNDARY LAYER DURING AFTERNOON.
SFC DEW POINTS GENERALLY MID-50S TO LOW-60S F AND FAVORABLY STEEP
LAPSE RATES ALOFT WILL SUPPORT MLCAPE IN 1000-2000 J/KG RANGE.
GREATEST VERTICAL SHEAR WILL BE ALONG WARM FRONT AND IN IMMEDIATE
VICINITY OF SFC LOW...WHERE SFC FLOW IS RELATIVELY BACKED...BENEATH
TIGHTENING MID-UPPER LEVEL HEIGHT GRADIENT. SMALLER HODOGRAPHS AND
MORE POTENTIAL FOR QUASI-LINEAR MODE SHOULD CHARACTERIZE
COLD-FRONTAL CONVECTIVE REGIME. STRONGER CAPPING AND WEAKER
CONVERGENCE WILL LESSEN COLD-FRONTAL TSTM POTENTIAL WITH SWWD
EXTENT.

PROGGED DIFFERENCES IN TIMING OF MID-UPPER WAVE AND SFC LOW ARE
MESOSCALE IN NATURE...BUT STILL CRUCIAL TO SPECIFYING ANY CORRIDOR
OF ENHANCED SVR POTENTIAL. ATTM FCST WILL START WITH MRGL
UNCONDITIONAL SVR PROBABILITIES...WITHIN WHICH SMALLER CATEGORICAL
OUTLOOK MAY BE NEEDED IN SUBSEQUENT OUTLOOKS.

SWODY2
SPC AC 100546

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1246 AM CDT SAT SEP 10 2011

VALID 111200Z - 121200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
PERSISTENT/DEEP-LAYER CYCLONE NOW OVER MID MS AND LOWER OH VALLEYS
IS EXPECTED TO BECOME OPEN-WAVE/POSITIVELY-TILTED TROUGH EARLY-MID
DAY-2 PERIOD. BY 12/00Z...500-MB TROUGH SHOULD EXTEND FROM LOWER
GREAT LAKES SWWD ACROSS OH...TN AND LA TO NWRN GULF. BY END OF
PERIOD...TROUGH SHOULD RESIDE OVER APPALACHIANS FROM NY-GA THEN
OFFSHORE MS RIVER MOUTH. BASAL SHORTWAVE TROUGH WILL PIVOT
CYCLONICALLY FROM AR-GA THROUGH PERIOD. FARTHER NW...MOISTURE
CHANNEL IMAGERY INDICATES SHORTWAVE TROUGH OVER SRN GULF OF AK.
THIS FEATURE SHOULD PENETRATE WRN NORTH AMERICAN MEAN RIDGE
DAY-1...REACHING SRN PARTS OF SK/MB BY 12/12Z. CUT-OFF MID-UPPER
CYCLONE SHOULD DRIFT ERRATICALLY OVER PORTIONS CENTRAL/SRN CA AND
ADJACENT COASTAL WATERS THROUGH PERIOD.

AT SFC...INITIALLY QUASISTATIONARY FRONTAL ZONE OVER N-CENTRAL FL
PENINSULA IS FCST TO PIVOT CYCLONICALLY THIS PERIOD AS APCHG
MID-UPPER WAVE STIMULATES WEAK FRONTAL-WAVE LOW FORMATION AT SFC.
ALTHOUGH PROGS STILL ARE RATHER INCONSISTENT ABOUT TIMING/LOCATION
OF THIS WAVE-LOW DEVELOPMENT...PATTERN SUPPORTS LOW POSITION OVER
SRN GA/NRN FL REGION...CONSISTENT WITH LATEST/00Z OPERATIONAL WRF
AND PRIOR/12Z ECMWF RUN. DURING LATTER HALF OF PERIOD...MOVEMENT OR
REFORMATION OF WARM FRONT IS EXPECTED EITHER OVER COASTAL AREAS OF
GA/SC...OR JUST OFFSHORE.

...MID-ATLANTIC TO UPPER OH RIVER REGION...
SCATTERED TSTMS IN CLUSTERS SHOULD DEVELOP DURING AFTERNOON...WITHIN
BROAD PLUME OF RESIDUAL BOUNDARY-LAYER MOISTURE CHARACTERIZED BY 60S
F SFC DEW POINTS. ISOLATED STG/DAMAGING GUSTS ARE POSSIBLE...THOUGH
SVR THREAT DOES NOT APPEAR WELL-ORGANIZED. MOST FAVORABLE
DEEP-LAYER FLOW SHOULD BE E OF APPALACHIANS TO MID-ATLANTIC
COAST...ALONG NWRN FRINGES OF MID-UPPER JET. WHILE TSTMS WILL BE
POSSIBLE AS FAR SW AS LOWER MS VALLEY...LOW-MIDLEVEL WINDS AND
DEEP-LAYER SHEAR EACH SHOULD WEAKEN WITH WWD EXTENT FROM PA ACROSS
OH AND REMAIN QUITE WEAK FARTHER SW.

...COASTAL GA/SC/NC...
SVR POTENTIAL DEPENDS STRONGLY ON POSITION OF RELATIVELY
HIGH-VORTICITY/HIGH-SRH WARM-FRONTAL CORRIDOR AND ITS SFC-BASED
EFFECTIVE INFLOW PARCELS...WITH RESPECT TO COAST. FCST SOUNDINGS
SUGGEST SUFFICIENTLY LARGE HODOGRAPHS FOR SUPERCELLS ALONG FRONT.
FROM LATE AFTERNOON THROUGH OVERNIGHT HOURS...CORRIDOR WILL LIE
BENEATH ERN RIM OF MID-UPPER JET FEATURING 70-90 KT 250-MB WINDS AND
40-45 KT 500-MB FLOW...CONTRIBUTING TO FAVORABLE DEEP-LAYER SHEAR.
WILL MAINTAIN MRGL UNCONDITIONAL PROBABILITIES ACROSS THIS REGION
GIVEN UNCERTAINTIES REMAINING OVER MESOBETA-SCALE BOUNDARY
POSITIONING THAT IS CRUCIAL TO ACTUAL SVR THREAT.

...NRN PORTIONS ND/MN...
AFTER 12/06Z...NARROW BUT STG BELT OF LARGE-SCALE ASCENT...BOTH IN
FORM OF LOW-LEVEL WAA AND MID-UPPER DCVA...SHOULD IMMEDIATELY
PRECEDE MID-UPPER LEVEL SHORTWAVE TROUGH ACROSS SRN PRAIRIE
PROVINCES. LOW-LEVEL MOISTURE WILL BE MRGL BUT SUFFICIENT TO
SUPPORT TSTMS IN THIS REGIME...SOME OF WHICH MAY PRODUCE HAIL. MOST
OF THE CONVECTION SHOULD REMAIN JUST N OF CANADIAN BORDER. SRN
FRINGE OF ACTIVITY MAY BRUSH ACROSS NRN MN/ND NEAR END OF PERIOD.
ATTM SVR POTENTIAL IS TOO CONDITIONAL/SMALL FOR AOA 5% LINE.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1237 AM CDT SAT SEP 10 2011

VALID 101200Z - 111200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
COMPLEX RETROGRADING UPR GYRE OVER THE OH/MID-MS VLYS WILL BEGIN TO
REVERSE COURSE ON SATURDAY AS IT OPENS INTO A WAVE AND PHASES WITH
THE POLAR WLYS ACROSS ON/QB THIS WEEKEND. TO THE W...UPR LOW OVER
CNTRL CA WILL SETTLE SWD TO A POINT OFF THE SRN CA COAST BY SATURDAY
NIGHT.

...SCNTRL/SERN AZ...
WSW MID/UPR-LVL FLOW WILL TEMPORALLY BACK TO DEEP SSWLYS AS THE
AFOREMENTIONED UPR LOW DIGS TOWARD SRN CA. WHILE MID-LVL DRY SLOT
EVOLVES OVER THE LWR DESERTS...PWATS IN EXCESS OF 1.50 INCHES OVER
NRN SONORA WILL BE TRANSPORTED NWD INTO PARTS OF SCNTRL/SERN AZ
SATURDAY AFTN/NIGHT. INTERFACE OF DRY/MOIST BOUNDARY LAYER AND
UPSLOPE SSWLY LLVL FLOW WILL AUGMENT DIURNAL CIRCULATION AND
CONTRIBUTE TO WDLY SCTD TSTMS BY LATE AFTN. INCREASED RIDGING ALOFT
AND DECREASING DEEP-LAYER WIND SPEEDS COMPARED TO FRIDAY WILL BE
NEGATIVE FACTORS IN WIDESPREAD SVR WEATHER. BUT...ANY TSTM THAT
FORMS WILL POSE DMGG MICROBURST AND/OR MRGLLY SVR HAILSTONE RISKS.

...SRN CA/SRN NV...
POCKET OF PWATS NEAR 1 INCH WILL ROTATE NWWD AROUND PERIPHERY OF THE
UPR LOW OVER SRN CA/SRN NV SATURDAY AFTN/EVE. FLOW ALOFT WILL
REMAIN FAVORABLY DIFFLUENT/DIVERGENT ACROSS THE REGION AND WHEN
COMBINED WITH MODEST BUOYANCY...SCTD TSTMS WILL BE LIKELY. ISOLD
STORMS WILL LIKELY MIGRATE NWWD ACROSS HIGH DESERT AMIDST STEEP LLVL
LAPSE RATES/MODESTLY COOL MID-LVL TEMPERATURES. AS A RESULT...ISOLD
DMGG MICROBURSTS AND/OR MRGLLY SVR HAIL CAN BE EXPECTED.
