EVENT...UPDATE TO PREVIOUS MESSAGE CONCERNING HEAVY RAINS ACROSS NE TX
.
SHORT TERM OUTLOOK VALID 0530-1000Z...MEDIUM/HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...LARGE MCS CONTINUING TO SLOWLY PUSH SE THROUGH
NE TX FROM INVOF KMKN TO KOSA.  GOES SOUNDER SHOWING PW VALUES IN THE
1.3"-1.5" IN THE IMMEDIATE VICINITY OF THE MCS WITH CAPE VALUES OF
4000+ J/KG ACROSS ERN TX.  VWP DATA SHOWING 35 KT SRLY FLOW AT 850MB
CONTINUING THE INFLOW FOR THE SYSTEM.  WHILE THE MOVEMENT HAS SHOWN
SOME ACCELERATION INTO THE GREATER INSTABILITY TO THE ESE...THERE
ARE STILL POINTS THAT HANG UP AT TIMES...ESPECIALLY ON THE SW FLANK
WHICH HAS BEEN HUNG UP OVER BROWN/HAMILTON/COMANCHE COUNTIES FOR ABOUT
THE LAST HOUR.  WHILE PW VALUES ARE NOT OVERLY IMPRESSIVE...THE LLVL
INFLOW IS FEEDING IN GREAT INSTABILITY AS WELL AS SOME SLIGHTLY HIGHER
MOISTURE...AROUND 1.6"-1.7"...WHICH IS CLOSER TO THE COAST.   WITH THE
CURRENT TREND OF SE/ESE MOVEMENT OF THE MCS BEGINNING...WOULD EXPECT
THE WIDESPREAD FLOODING THEREAT TO DECREASE OVER TIME ACROSS NE/E TX.
HOWEVER THERE STILL REMAINS THE THREAT FOR HANGUPS AND PERIODS OF
BACKBUILDING...PARTICULARLY ON THE SW FLANK...WHICH COULD STILL PRODUCE
RATES OF 3.0"/HR.
