COASTAL BEND FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
245 AM CDT TUE JUL 2 2002

DISCUSSION...CONVECTION DEVELOPING/TRAINING EARLY THIS MORNING FROM
60NM EAST OF PORT ARANSAS NORTHWESTWARD ACROSS CRP AND OVER LIVE OAK
COUNTY WHERE FLASH FLOOD WARNING CURRENTLY EXISTS.  AFTER EVALUATING
AVN/ETA/MESOETA OUTPUT..CONVECTION APPEARS TO BE IN PERFECT
ALIGNMENT WITH AN AREA OF 1000-925 MB Q-VECTOR CONVERGENCE FROM THE
MESOETA.  THE TRAINING NATURE OF THE CONVECTION WILL BECOME
PROGRESSIVE OVER THE NEXT FEW HOURS AND TRANSLATE NORTHWARD ACROSS
THE REMAINDER OF THE ERN FA AS MID-UPR LEVEL VORT SPINS OVER THE
HILL COUNTRY.  WILL LEAN TOWARD THE ETA/MESOETA SUITE GIVEN THE
ABOVE WHICH ALSO PROPAGATES THE VORT MAX TO THE SOUTHWEST WITH THE
BROAD SYNOPTIC-SCALE TROF EXTENDING FROM THE PANHANDLE SOUTHWARD
ALONG THE RIO GRANDE.  LOWER VAPOR CONTENT SEEN IN WV IMAGES OVER
THE RIO GRANDE PLAINS WILL SERVE TO INHIBIT EARLY RAINFALL
DEVELOPMENT..HOWEVER WILL ENHANCE CONVECTION BY LATE MORNING/THIS
AFTERNOON AS THE VORT SINKS SOUTHWARD AND STEEPENS LAPSE RATES AND
ENHANCES LIFT IN A MORE CONVECTIVELY UNSTABLE ENVIRONMENT..GIVEN THE
DRIER MID-LEVEL AIR.  250 MB LEFT-EXIT REGION OF 50 KNOT JET STREAK
DIGGING SWD TO THE WEST OF THE RIO GRANDE WILL ALSO AID IN ASCENSION.

ACROSS THE EAST..WILL PLACE THE SE CWA BACK INTO THE FLASH FLOOD
WATCH.  FLOOD GUIDANCE IS 0.5 TO 1.5 INCHES FROM NW TO SE OVER THE
CWA..WITH 1-HR TOTALS OF 0.7 IN SAN PATRICIO AND 1.2 FOR NUECES AND
KLEBERG.  AS THE VORT SINKS SWD..EXPECT A GENERAL SWATH OF PVA TO
TAP THE 2+ PWATS TO DEVELOP ADDITIONAL CONVECTION OVER THE CWA
TODAY.  RAINFALL POTENTIAL WILL GRADUALLY DECREASE FROM EAST TO WEST
ON WEDNESDAY AS DRIER AIR FROM THE EAST BEGINS TO OVERSPREAD THE
AREA..INITIALLY IN THE MID-LEVELS AS THE UPR VORT SHIFTS TO THE
NORTH AND RIDGING OCCURS FROM THE NORTHEAST.  MOISTURE DEPTH
INCREASES ONCE AGAIN AS AN UPPER DISTURBANCE TRACKS WESTWARD AROUND
THE RIDGE TOWARD TEXAS NEXT WEEKEND.

MARINE...WILL MAINTAIN SCEC CONDITIONS THROUGH THURSDAY GIVEN
SUFFICIENT WIND WITHIN UNSTABLE LOW-LEVEL LAPSE RATES. WINDS FALL
BELOW ADVISORY/CAUTION LEVELS FRIDAY/SATURDAY AS SURFACE PRESSURE
GRADIENT WEAKENS CONSIDERABLY. 500HPA DISTURBANCES SUPPORT SCATTERED
CONVECTION THIS MORNING AND AGAIN TONIGHT/WEDNESDAY MORNING. 500HPA
RIDGING/LOWERING PWATS INHIBITS CONVECTION THEREAFTER THROUGH MOST
OF FRIDAY. THEN AN APPROACHING TROPICAL WAVE/INCREASING PWATS/WEAK
SURFACE PRESSURE GRADIENT SUPPORTS ISOLATED CONVECTION.
