DISCUSSION...
WEAKENING LINE OF TSTMS HAS MADE ITS WAY INTO THE I-30 CORRIDOR OF
NE TX...EXTENDING SWRD TO THE I-20 CORRIDOR NEAR TYR. SEVERE THREAT
HAS ALL BUT ENDED FOR THE REMAINDER OF THE EVENING SO REMOVED ANY
ASSOCIATED WORDING IN THE GRIDS AND ZONE UPDATE. STILL CANNOT RULE
OUT SOME GUSTY WINDS ALONG THIS LINE AS IT CONTINUES FARTHER EAST
INTO S AR/N LA WITH GUSTS NEAR 30 MPH. ELSEWHERE ACROSS THE
REGION...LIGHT TO MODERATE SHWRS HAVE BEEN ONGOING FOR MUCH OF THE
EVENING SO ANY SFC BASED INSTABILITY HAS BEEN MOSTLY ERASED AHEAD
OF THE APPROACHING LINE OF TSTMS. EXPECT THE UPPER TROF TO EJECT
NEWRD OVERNIGHT FROM THE TX PANHANDLE ACROSS THE RED RIVER VALLEY
AND INTO WRN AR BY SUNRISE ON SUNDAY. THIS WILL HELP DRIVE THE
COLD FRONT INTO OUR REGION AFTER MIDNIGHT AND THROUGH SUNDAY WITH
LIGHT RAIN CONTINUING FOR MUCH OF THE DAY AS MOISTURE WRAPS AROUND
THE LOW. SO FOR THE REMAINDER OF TONIGHT...UPDATE IS MAINLY TO
REMOVE SEVERE WORDING AND ADJUST POPS SLIGHTLY HIGHER IN MOST
AREAS. LOADED NEW NAM WINDS AND QPF NUMBERS AS WELL WITH 1-2
INCHES OF RAINFALL EXPECTED FOR MOST LOCATIONS BY THE TIME THE
EVENT WRAPS UP LATE SUNDAY. UPDATED PRODUCTS HAVE ALREADY BEEN
