MORNING WATER VAPOR LOOPS SHOW A LARGE UPPER LOW OFF THE CA COAST.

...DISCUSSION...
THE MEDIUM RANGE WILL CONTINUE TO SEE THE PATTERN OF ERN PAC
SHORTWAVE TROUGHS AMPLIFYING INTO CLOSED LOWS ALONG THE CA
CST...THEN EJECTING EWD INTO THE SRN PLNS. THE LEAD UPR SYSTEM THAT
IS LIKELY TO PRODUCE A ROUND OF SEVERE WEATHER ON THU-THU NIGHT
ACROSS THE SRN PLNS...OZARKS AND MID-SOUTH WILL EJECT NEWD THROUGH
THE TN/OH VLYS AND WEAKEN ON FRIDAY. MODIFIED GULF MOISTURE
ENTRAINMENT IS LIKELY AS FAR N AS THE TN VLY AND SOME SVR MAY OCCUR
IN THAT AREA ON FRIDAY...THOUGH NOT WIDESPREAD ENOUGH FOR A MEDIUM
RANGE SVR OUTLOOK.

00Z ECMWF/GFS ARE WITHIN REASONABLE AGREEMENT REGARDING THE SECOND
UPR LOW PROGGED TO MOVE INTO THE SRN HIGH PLAINS SATURDAY NIGHT.
LLVL MOISTURE WILL NOT BE SHOVED TOO FAR S BY THE LEAD SYSTEM AND
SHOULD RAPIDLY RETURN NWD INTO TX. AVAILABILITY OF RICHER THETA-E
AND DEVELOPMENT OF THE LEE-LOW/DRYLINE ACROSS WCNTRL TX WILL BE FOCI
FOR SATURDAY EVENING TSTM DEVELOPMENT. SSWLY LLJ SHOULD INTENSIFY
SATURDAY NIGHT WITH A POSSIBLE ORGANIZED SVR EVENT EVOLVING
OVERNIGHT SATURDAY NIGHT/EARLY SUNDAY ACROSS CNTRL/ERN TX.

AS THE UPR SYSTEM CONTINUES TO INTENSIFY...LARGER SCALE HEIGHT FALLS
WILL SPREAD TOWARD THE LWR MS/TN VLYS SUNDAY. ATTENDANT SFC LOW
SHOULD MIGRATE NEWD ALONG THE INTENSIFYING WRMFNT TOWARD TN SUNDAY
NIGHT WITH A STOUT SWLY LLJ TRANSLATING EWD THROUGH LA...MS AND AL.
ORGANIZED SVR WEATHER WILL PROBABLY DEVELOP UPSCALE FROM THE MORNING
ACTIVITY ACROSS ERN TX AND REACH THE TN VLY-DIXIE SUNDAY NIGHT.

VALID 091200Z - 101200Z

...THERE IS A SLGT RISK OF SVR TSTMS OVER A LARGE PART OF THE SRN
PLNS...OZARKS AND MID-SOUTH...

...SYNOPSIS...
A LEAD UPR TROUGH MOVING INTO THE INTERIOR WEST ON WEDNESDAY WILL
TRANSLATE EWD ACROSS THE CNTRL/SRN PLNS AND LWR OH VLY THURSDAY.
KICKER SYSTEM WILL BE THE NEXT AMPLIFYING SHORTWAVE TROUGH THAT WILL
CLOSE INTO A LOW AND DROP SWD ALONG THE CA CST DURING THE DAY 3 PD.
AT THE SFC...LEE-LOW WILL DEEPEN THURSDAY MORNING OVER THE SRN HIGH
PLNS...THEN DEVELOP EWD ALONG THE OK/KS BORDER BY 00Z FRI...THEN TO
NEAR KSTL BY 12Z FRI. A DRYLINE WILL MIX QUICKLY EWD INTO CNTRL
OK/ERN TX THURSDAY AFTN BEFORE BEING OVERTAKEN BY A SEWD MOVING
CDFNT THURSDAY NIGHT.

...SRN PLNS TO THE MID-SOUTH...
RETURN FLOW WILL INCREASE STEADILY WEDNESDAY THROUGH THURSDAY AHEAD
OF THE APCHG UPR SYSTEM. MODIFIED GLFMEX MOISTURE...CHARACTERIZED
BY SFC DEW POINTS IN THE MID 50S TO LWR 60S...WILL ADVECT THROUGH
ERN MEXICO...THEN ARC NEWD ACROSS CNTRL/ERN TX...ERN OK...AND THE
OZARKS BY THURSDAY EVE. THIS DEEPENING MOIST BOUNDARY LAYER WILL
INITIALLY BE CAPPED AS A STRONG EML STREAMS EWD BENEATH THE UPR LOW.
HOWEVER...90+ METER HEIGHT FALLS AND ABRUPT COOLING ALOFT WILL TEND
TO WEAKEN THE CAP BY LATE AFTN AND EXPECT TSTMS WILL ERUPT ALONG THE
DRYLINE/TRIPLE POINT REGION FROM SCNTRL KS SWD INTO ERN TX.
MAGNITUDE OF LAPSE RATES/MODEST INSTABILITY AND 60-70 KTS WLY H5
FLOW WILL BE SUFFICIENT FOR ORGANIZED TSTMS WITH LARGE HAIL...DMGG
WINDS AND PERHAPS TORNADOES. SVR THREATS WILL LIKELY EXTEND
DOWNSTREAM TOWARD THE MID-SOUTH/OZARKS OVERNIGHT AS THE 50 KT SWLY
LLJ QUICKLY SHIFTS EWD TO ALONG THE LWR MS VLY.

VALID 081200Z - 091200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
AMPLIFIED FLOW REGIME WILL CONTINUE ON WEDNESDAY. ERN STATES UPR
TROUGH WILL BE REINFORCED DURING THE DAY AS A SPEED MAX QUICKLY
DROPS SEWD FROM THE CANADIAN PRAIRIES INTO THE OH VLY.
MEANWHILE...UPR LOW CURRENTLY IN THE E PAC BASIN...WILL ARRIVE IN CA
BY 12Z WEDNESDAY...THEN QUICKLY MOVE EWD ACROSS THE INTERIOR WEST ON
WEDNESDAY NIGHT.

...CNTRL/SRN CA...
COLD TEMPERATURES ALOFT /AOB MINUS 25 DEG C AT H5/ ASSOCD WITH THE
UPR LOW WILL LINGER ACROSS CNTRL/SRN CA THROUGH EARLY WEDNESDAY AFTN
BEFORE TRANSLATING INTO THE INTERIOR WEST LATER IN THE DAY. ISOLD
TSTMS MAY BE ONGOING AT 12Z WEDNESDAY ALONG THE CNTRL/SRN CA CSTS.
ADDITIONAL STORMS COULD FORM IN THE INTERIOR VLYS DURING THE AFTN.
LOW WBZ LEVELS MAY YIELD SMALL HAIL IN THE STRONGEST STORMS...BUT
SVR THREATS WILL REMAIN LOW.

...INTERIOR WEST...
HEIGHTS WILL BEGIN TO FALL ACROSS THE INTERIOR WEST ON WEDNESDAY AS
THE UPR LOW BEGINS TO ACCELERATE OUT OF CA. SUFFICIENT MOISTENING
AND STEEP LAPSE RATES WILL CONTRIBUTE TO DIURNALLY-ENHANCED TSTM
THREAT FROM NEAR THE CANADIAN BORDER SWD TO THE FOUR-CORNERS REGION.
HIGHEST POTENTIAL FOR TSTMS WILL BE ACROSS ERN ID...NRN UT...SWRN WY
AND NWRN CO ALONG THE EXIT REGION OF THE MID-LVL JET. A SECONDARY
MAXIMUM IN PROBABILITIES WILL SPREAD ACROSS NRN AZ INTO NWRN NM
DURING THE EVENING...ALONG THE TRACK OF COLDEST TEMPERATURES ALOFT.

...OH VLY...
SPORADIC TSTMS WILL LIKELY ACCOMPANY THE CLIPPER-TYPE SYSTEM DIGGING
INTO THE OH VLY WEDNESDAY AFTN/EVE. HERE...MODEST UVV/S COMBINED
WITH A STEEP LAPSE RATE ENVIRONMENT WILL CONTRIBUTE TO A FEW HOURS
OF POSITIVE BUOYANCY AND POTENTIAL CB TOPS INTO THE ICING RANGE OF
MINUS 20 DEG C.

VALID 071200Z - 081200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
AMPLIFIED LARGE SCALE PATTERN WILL PERSIST OVER THE CONUS...WITH THE
PRIMARY CONVECTIVE/ISOLATED TSTM POTENTIAL TODAY ACROSS CA/ORE TIED
TO THE EASTWARD MIGRATION OF AN UPPER LOW CURRENTLY NEAR 34N/130W.
OTHERWISE...COOL/STABLE CONDITIONS WILL PRECLUDE TSTMS ACROSS THE
REMAINDER OF THE CONUS.

...CA...
AS THE UPPER LOW NEARS THE CA COAST...LEADING FRONTAL CONVECTIVE
BAND /WITH SOME EMBEDDED TSTM POTENTIAL/ SHOULD MOVE INLAND ACROSS
CA THROUGH LATE MORNING/EARLY AFTERNOON. IN THE WAKE OF THIS INITIAL
CONVECTIVE BAND...MODEST HEATING BENEATH THE UPPER LOW /-25C AT 500
MB/ WILL SUPPORT THE DEVELOPMENT OF WEAK CAPE THIS AFTERNOON...WITH
SBCAPE GENERALLY LIMITED TO 250 J/KG. THIS WEAK BUOYANCY...ALONG
WITH A POST-CONVECTIVE BAND TENDENCY FOR VEERED LOW LEVEL FLOW
ACROSS THE CENTRAL VALLEY...IS EXPECTED TO LIMIT THE SEVERE RISK
TODAY. NEVERTHELESS...ISOLATED TSTMS WILL BE POSSIBLE BY LATE
AFTERNOON/EARLY EVENING AS THE UPPER VORT NEARS THE COAST...WITH THE
POSSIBILITY OF SMALL HAIL ACROSS THE CENTRAL CA COASTAL AREAS.
