SOUTHEAST TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
1010 PM CST MON NOV 26 2001
SEVERAL ISSUES TO CONTEND WITH TONIGHT INCLUDING RAIN CHANCES...
SEVERE POTENTIAL AND WIND SHIFT. OVERALL COVERAGE OF PRECIP WILL
REMAIN HIGH THROUGH WEDNESDAY BUT AM NOT CONFIDENT WITH SEVERE
THREAT TONIGHT. WET BULB ZERO IS STILL AOA 12K FT SO HAIL THREAT
SHOULD REMAIN MINIMAL. CAPES ARE NOT REAL HIGH AND HELICITY VALUES
ARE ALSO ON THE LIGHT SIDE. A LAYER OF DRY AIR ABOVE 85H DOES FAVOR
SOME DOWNBURST POTENTIAL. SVR WATCH RUNS UNTIL 1 AM...SO WILL
CONTINUE TO MONITOR. WHAT IS OF SOME CONCERN IS THE TRAINING OF
ECHOES WHICH HAS BEGUN TO DEVELOP. IF THIS TREND CONTINUES...SOME
LOCALLY HEAVY RAIN WILL OCCUR. AMOUNTS OF 2 TO 3 INCHES ARE POSSIBLE
BY MORNING (MAYBE HIGHER) IF THIS SITUATION PERSISTS. WILL UPDATE
ZONES TO RAISE RAIN CHANCES AND ADD LOCALLY HEAVY RAIN.
TUESDAY INTO WEDNESDAY LOOK RATHER DISTURBING. PWS REMAIN AOA 1.2
INCHES WITH AN INVERTED TROF DEVELOPING ALONG THE COAST. COLD FRONT
APPROACHING THE AREA WILL STALL NEAR THE COAST AS IT BECOMES
PARALLEL TO THE UPPER FLOW. OVER-RUNNING (I KNOW?) PRECIP TO DEVELOP
INLAND AS SOUTHERLY 85H WINDS OF 40 KNOTS OVERRIDE 15 KT NORTHERLY
SURFACE WINDS. SE TX ALSO LIES IN A RRQ OF A DEPARTING 120 KT JET
MAX THROUGH WEDNESDAY NIGHT WHICH WILL FURTHER ENHANCE PRECIP
POTENTIAL. SINCE WET BULB ZERO TEMPS ARE COOLER AND LAPSE RATES
REMAIN CONDITIONALLY UNSTABLE...FEEL POTENTIAL WILL INCREASE FOR
HAIL THREAT.
IF THIS ISNT ENOUGH...00Z ETA MODEL SHOWS ENOUGH LIFT...SATURATION
AND COLD TEMPERATURES THAT A MIX OF SLEET...FREEZING RAIN AND SNOW
IS POSSIBLE OVER THE NORTHERN ZONES OF SE TX. WAY TOO EARLY TO TELL
BUT SOUNDING DATA SUPPORTS A MIX NORTH OF HOUSTON AND POSSIBLY SNOW
NEAR CLL BEFORE PRECIP ENDS THURSDAY MORNING. ANY PRECIP WHICH FALLS
AT THIS TIME WILL BE LIGHT. WHAT A WEEK
