NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Jul 21, 8:22 AM CST, 38 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CORPUS CHRISTI TX 922 AM CDT WED JUL 21 2004 .UPDATE...SCATTERED SHOWERS WITH A FEW TSRA CONTINUE OVER THE NORTHERN COASTAL BEND THIS MORNING...WITH DEEPER CONVECTION LOCATED ABOUT 150 NM EAST OF BAFFIN BAY. 12Z KCRP SOUNDING SHOWS PWAT VALUES AT 1.45 INCHES. UPPER-LOW CONTINUES ITS PROGRESSION TO THE WEST ACROSS SOUTH TEXAS. CURRENT WATER VAPOR LOOP DEPICTS CYCLONIC CIRCULATION LOCATED JUST TO THE EAST OF BAFFIN BAY. THIS LOW WILL CONTINUE MOVING TO THE WEST TODAY...PUTTING THE EASTERN AREAS OF THE CWA IN A MORE FAVORABLE SETUP FOR CONVECTION. THE LACK OF MOISTURE WILL BE THE MAIN HINDRANCE FOR CONVECTIVE DEVELOPMENT. EXPECT SOME ISOLATED TSRA THIS AFTERNOON ALONG THE SEA-BREEZE AS WELL. TEMP FORECAST LOOKS GOOD TODAY BUT WILL RAISE POPS JUST A BIT TODAY TO INCLUDE SLIGHT CHANCE OVER ALONG THE HIGHWAY 77 CORRIDOR. WINDS WILL BE A BIT STRONGER TODAY AND MAY NEED TO FLAG THE SOUTHERN BAYS FOR SCEC CONDITIONS. WINDS WILL APPROACH 15 TO 20 KNOTS THIS AFTERNOON AS THE PRESSURE GRADIENT TIGHTENS...BUT DO NOT EXPECT A PROBLEM WITH THE NORTHERN BAYS OR GULF WATERS. SCEC CONDITIONS ARE POSSIBLE OVER THE GULF TONIGHT. WILL SEND OUT A QUICK UPDATE TO REFLECT CURRENT THINKING. 94/MJ && .PREVIOUS DISCUSSION... .SHORT-TERM (TODAY THROUGH THURSDAY)...250HPA CYCLONE OVER THE NORTHWESTERN GLFMEX TRACKS W/SW AND PLACES THE CWA/MWA IN THE FAVORABLE EASTERN FLANK. PREFER THE LOWER PWATS PER THE GFS TODAY AS THE GOES SOUNDER DATA SHOWS THE HIGHEST PWATS ADVECTING NORTH WITH THE WESTERN EDGE ERODING. BOUNDARY LAYER FORCING IS RATHER MENIAL AND 700HPA TEMPERATURES ARE STILL TOO WARM TODAY SO WILL INDICATE JUST SLIGHT CHANCE POPS AND GENERALLY RESERVE THEM FOR THE NORTHEASTERN CWA AND THE WATERS. A DEEPER S/SE TROPOSPHERIC FLOW OVERSPREADS THE AREA OVERNIGHT/THURSDAY AND ALLOWS FOR HIGHER PWATS. 700-300HPA DIFFERENTIAL VORTICITY ADVECTION OCCURS WITH THE 700HPA/850HPA THETA-E AXES ALSO ALIGNED ACROSS THE REGION. BOUNDARY LAYER FORCING IS ALSO SOMEWHAT BETTER. WILL INDICATE SLIGHT CHANCE POPS AND RESERVE LOW-END CHANCE POPS FOR THE NORTHEASTERN COUNTIES AS A SOUTHERLY 850HPA FLOW PREVAILS. INCREASING LOW-LEVEL JET AND A THERMAL GRADIENT WILL LIKELY BRING MARGINAL SCEC CONDITIONS TO THE NEARSHORE/OFFSHORE WATERS TONIGHT AND THE SOUTHERN BAYS ON THURSDAY. LOW-LEVEL THICKNESSES SHOW ONLY A SMALL VARIATION SO WILL HOVER AROUND PERSISTENCE WITH RESPECT TO TEMPERATURES. && .LONG-TERM (THURSDAY NIGHT THROUGH TUESDAY)...RESIDUAL MOISTURE AND DEEP SOUTH/SOUTHEAST FLOW LEFTOVER FROM THE DEPARTING MID/UPR LOW OVER MEXICO WL MAINTAIN ISOLATED POPS THROUGH FRI. A RDG AXIS WL SLOWLY BUILD ACROSS THE RGN BEGINNING ON FRI AND CONTINUING INTO THE WEEKEND. SOUTH TX WL ONCE AGAIN DRY OUT AS BOUNDARY LYR FLOW FROM THE GULF WEAKENS AND AS SUBSIDENCE INCREASES ALOFT. THE RELATIVELY DRY AIRMASS ALONG WITH A DEVELOPING LANDBREEZE AT NIGHT AND WK SEABREEZE DURING THE DAY WL PRODUCE DAYTIME HIGHS SLIGHTLY ABV NORMAL AND OVERNIGHT LOWS SLIGHTLY BELOW NORMAL. THE MID/UPR RDG AXIS DOES BEGIN TO BREAK DOWN ON MON AND TUE AS A S/WV TROUGH AXIS DIGS SWD THROUGH THE PLAINS. MOISTURE ADVECTION ALONG WITH WK FORCING ALOFT AND A SLIGHTLY COOLER TROPOSPHERIC COLUMN WL PROVIDE THE POTENTIAL FOR RAINFALL ON MON AND TUE. RIGHT NOW WL KEEP POPS NO HIGHER THAN SLIGHT CHC GIVEN THE MODEL TRENDS OVER THE PAST SVRL DAYS (EACH RUN IS DELAYING THE RAINFALL AND GETTING DRIER). && .PRELIMINARY POINT TEMPS/POPS...
