REFLECTIVITY DATA FROM KDYX INDICATES ONE CLUSTER OF THUNDERSTORMS
APPROACHING BROWNWOOD...WITH ANOTHER THUNDERSTORM INTENSIFYING OVER
SHACKELFORD COUNTY.  LATEST TRENDS ALSO INDICATE INCREASING
CONVECTIVE ACTIVITY ALONG A SOUTHWEST-TO-NORTHEAST ORIENTED LINE
FROM MARTIN COUNTY TO JONES COUNTY.  DUE TO WEAKNESSES IN MID-LEVEL
FLOW...PER 05/00Z KFWD RAOB...THUNDERSTORMS ARE ONLY SLOWLY MOVING
EASTWARD...AND SHOULD NOT REACH THE DFW METROPLEX UNTIL AFTER 2
AM.  LATEST SHORT TERM GUIDANCE FROM THE RUC40 IS NOT AGGRESSIVE IN
DEVELOPMENT OF QPF OVER NORTH TEXAS.  ANALYSIS OF 05/00Z 850 MB DATA
SHOWS THAT WEAK RIDGING IS STILL LOCATED OVER EAST TEXAS...WITH
STEEPEST HEIGHT GRADIENT AND AXIS OF LOW-LEVEL JET FOCUSED MORE
TOWARD WEST-CENTRAL AND SOUTHWEST TEXAS.  THIS IS LIKELY THE REASON
FOR LOW QPF IN MODEL SOLUTIONS.  HOWEVER...BASED ON CURRENT RADAR
TRENDS AND PROXIMITY OF THUNDERSTORMS TO WESTERN COUNTIES...WILL NOT
LOWER POPS OR CHANGE ANY ELEMENTS OF THE CURRENT FIRST PERIOD
FORECAST AT THIS TIME.
