.DISCUSSION...
A FEW SHOWERS STILL GOING FROM THIS MORNINGS S/W IMPULSE THAT
MOVED INTO THE COASTAL AREAS NOW OVER NORTHEAST AREAS AND ISOLATED
STORMS IN THE GULF. BOUNDARY STILL EVIDENT FROM AROUND BEAUMONT TO
HOUSTON TO COLLEGE STATION AND LIFTING NORTH. LIFT LOOKS TO BE
INCREASING ACROSS S TX AND WHERE PRESSURES HAVE FALLEN 3 MB IN THE
LAST FEW HOURS.

VERY ACTIVE WEATHER EXPECTED OVERNIGHT AND THROUGHOUT THE DAY
MONDAY FOR SETX.

EXPECTING RAPID INTENSIFICATION OF STORMS ALONG THE DRYLINE IN
WESTERN HILL COUNTRY REGION THIS EVENING AND AS UPPER JET SLOWLY
SHIFTS EASTWARD OVER SETX THESE STORMS SHOULD ADVANCE EASTWARD
MOVING INTO THE WESTERN CWA BETWEEN MIDNIGHT AND 4 AM THEN INTO
THE CENTRAL AREAS PERHAPS AS EARLY AS 6 AM. SURFACE LOW TRACKING
JUST INLAND FROM S TX THROUGH CRP INTO GALVESTON BAY AREA AROUND
18Z WILL HELP TO INCREASE LL EASTERLY FLOW AND SHEAR IN OUR
HODOGRAPHS. (COULD ALSO HELP TO MAKE FOR SOME LIGHT-MODERATE
ADVECTION FOG EARLY IN THE MORNING FOR COASTAL AREAS) PW SHOULD
CLIMB TO NEAR 1.8-2" WITH THE ARRIVAL OF THE STORMS AND FORECAST
SOUNDINGS ARE IMPRESSIVE. HIGH CAPE ENVIRONMENT 1900-4000J/KG
(HIGHER CAPE SCENARIOS ARRIVE MONDAY AFTERNOON. MEDIAN CAPE VALUES
AROUND 2500 SEEM MORE REASONABLE. SHEAR IS SUFFICIENT FOR
SUPERCELLS AND BOWING SEGMENTS (EHI OF 1.5 TO 4) WITH STRONG MID
LEVEL SW FLOW TO BOOT. EXPECT TO SEE TRAINING AND REDEVELOPMENT
ON SW FLANKS SO SOME BACK BUILDING MAY OCCUR ACROSS THE CENTRAL
CWA MONDAY MORNING/EARLY AFTERNOON. HAVE RAISED POPS FOR MONDAY
AND WILL CARRY HEAVY RAINFALL THREAT AND SEVERE AS WELL CENTERED
AROUND MONDAY...AFTER MIDNIGHT TONIGHT MAY REACH INTO WESTERN CWA.
RAINFALL SHOULD BE WIDESPREAD AND A LARGE EAST TO WEST SWATH OF
1-2" AMOUNTS LOOKS LIKELY AND IF THE TRAINING/BACK-BUILDING
REDEVELOPMENT SHOULD TAKE PLACE THEN ISOLATED AMOUNTS MAY EXCEED
5"...MONDAY LOOKS LIKE A WASHOUT. MAY NEED A FLASH FLOOD WATCH AND
WILL BE LETTING EVENING SHIFT EVALUATE THE 00Z GUIDANCE TO MAKE
THAT CALL. SECOND S/W ROTATING AROUND THE MAIN TROUGH COULD BE
ENOUGH TO KEEP SOME LINGERING POPS MONDAY NIGHT CENTERED MAINLY
OVER THE NORTHEASTERN AREA. IMPRESSIVE LATE SEASON COLD FRONT
POURS DOWN AND THROUGH THE AREA EARLY TUESDAY MORNING PROBABLY OFF
THE COAST BY 09-12Z. WINDS IN THE WAKE OF THE FRONT WILL LIKELY
SUPPORT WIND ADVISORIES FOR COASTAL COUNTIES AND PERHAPS EVEN A
FEW MORE COUNTIES INLAND. DRY HIGH PRESSURE FILLS AND THE
REMAINDER OF THE WEEK LOOKS LIKE VERY PLEASANT WEATHER WITH LIGHT
WINDS/ABUNDANT SUNSHINE/VERY LOW RAIN CHANCES IF ANY. RETURN FLOW
COMES BACK IN SATURDAY AND DEEPER MOISTURE SHOULD ARRIVE NEXT
SUNDAY. 45

&&
.MARINE...
INCREASING SOUTHEAST WINDS ARE POSSIBLE TONIGHT AS A STORM SYSTEM
STRENGTHENS. OUR NEXT BEST CHANCE FOR SEEING MARINE AREA SHOWERS AND
THUNDERSTORMS COMES MONDAY THROUGH MONDAY EVENING AS ACTIVITY MOVES
INTO THE AREA FROM THE WEST AND NORTHWEST IN ASSOCIATION WITH THE
STORM SYSTEM. SOME STORMS COULD BE STRONG OR SEVERE...AND LOCALLY
HEAVY RAINFALL IS POSSIBLE TOO. A STRONG COLD FRONT WILL MOVE OFF
THE COAST MONDAY NIGHT...AND BREEZY NORTH WINDS WILL DEVELOP BEHIND
THE BOUNDARY. TUESDAY THROUGH TUESDAY NIGHT...CAUTION FLAGS ARE
LIKELY AND ADVISORIES MIGHT BE NEEDED. GRADUALLY WEAKENING NORTH
WINDS AND LOWERING SEAS CAN BE EXPECTED FOR THE REMAINDER OF THE
WEEK AS HIGH PRESSURE BUILDS INTO THE AREA.  42
