345 PM CDT THU APR 29 2004

.DISCUSSION...
STRONG MID-SPRING COLD FRONT MAKING PROGRESS ACROSS HIGH PLAINS OF
TEXAS PANHANDLE THIS AFTERNOON AND IS BEGINNING TO ENTER FAR
NORTHWEST PART OF FA.  APPEARS RUC HAS FAIRLY DECENT HANDLE ON
FRONTAL POSITION AND PLACES IT FROM NEAR FAIRVIEW TO SOUTH OF ELK
CITY TO AROUND HOLLIS BY 10 PM.  STORMS DEVELOPING AHEAD OF FRONT IN
TX PANHANDLE SO APPEARS MOST LIKELY AREA FOR INITIAL SEVERE
DEVELOPMENT WILL BE ACROSS SOUTHWEST PARTS OF FA.  FORECAST SHEAR
PROFILES A LITTLE MORE FAVORABLE ACROSS THIS AREA ALSO.  EXACT
EVOLUTION OF STORMS THIS EVENING UNCLEAR BUT AS LLJ INTENSIFIES
OVERNIGHT BEST CHANCE FOR CONVECTION SHOULD BE ACROSS NORTH
CENTRAL/ CENTRAL PARTS IN VICINITY OF JET AXIS.

OVERALL SETUP FOR ADDITIONAL STORMS ON FRIDAY WILL BE DEPENDENT
UPON AMOUNT OF CONVECTIVE DEVELOPMENT THIS EVENING BUT WOULD IMAGINE
THAT COLD FRONT WILL BE FARTHER SOUTH THAN ETA/GFS SUGGEST GIVEN
CURRENT TRENDS.  HAVE THEREFORE LOWERED TEMPS ACROSS NORTHERN
SECTIONS FOR HIGHS TOMORROW AND LOWS FOR TONIGHT.

EXPECT SIMILAR WEATHER ON FRIDAY WITH CENTRAL AND SOUTHERN PARTS
OF THE FA HAVING THE BEST CHANCE FOR SEVERE THUNDERSTORMS.  WILL
GRADUALLY DRY THINGS OUT GOING INTO SATURDAY MORNING AS FRONT
PUSHES INTO NORTHEAST PARTS OF TEXAS.  REST OF EXTENDED FORECAST
WILL BE DRY WITH BELOW NORMAL TEMPS TO START THE WORK WEEK.
