SOUTHEAST TEXAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 235 PM CST SUN DEC 17 1995 EXTREMELY HEAVY RAIN CONTINUES ALONG AND INLAND OF THE E-W OUTFLOW BOUNDARY. LAST COUPLE OF HOURS OF SATELITE IMAGERY SUGGESTS BOUNDARY LIFTING SLOWLY NORTHWARD. IF THIS TREND CONTINUES SUSPECT HEAVY RAIN FOCUS COULD SHIFT FURTHER INLAND. RAINFALL TOTALS IN EXCESS OF 10 INCHES LIKELY ALREADY IN PORTIONS OF BRAZORIA AND MATAGORDAY COUNDIES WITH LARGE AREA IN EXCESS OF 5 INCHES. ANOTHER AREA OF 3 TO 5 INCH RAINS OCCURRED OVERNIGHT FROM BURLESON COUNTY EAST THROUGH LIVINGSTON. WSR-88D ESTIMATES WERE 30% TO 50% BELOW RAINGAGE TOTALS. AGREE WITH SWODY1 AND QPFERD THAT ALL FEATURES NECESSARY FOR EXCESSIVE RAIN AND/OR SEVERE WEATHER WILL REMAIN IN PLACE THROUGH TONIGHT. A WELL DEFINED SPEED MAX DROPPING INTO BASE OF SW LOW THIS AFTERNOON IS EXPECTED TO ENTER SOUTH TEXAS TONIGHT. THE COUPLING OF THAT FEATURE WITH THE LOW LEVEL JET AND THETAE RIDGE OVER OR JUST WEST OF SOUTHEAST TEXAS AND THE LARGE ENTRANCE REGION OF THE MAIN JET OVER MID/UPPER MS VALLEY SHOULD RESULT IN MAJOR CONVECTIVE DEVELOPMENT FROM SOUTH CENTRAL TEXAS EASTWARD.
