AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
941 PM CDT SAT JUN 17 2000

RADARS CONTINUE TO SHOW SCATTERED SHOWERS AND THUNDERSTORMS ACROSS ABOUT THE
SOUTHERN HALF OF THE AREA THIS EVENING. MOST OF THIS ACTIVITY HAS DEVELOPED
ALONG TWO BOUNDARIES. THE FIRST WAS AN OLD OUTFLOW BOUNDARY THAT HAD STALLED
ACROSS THE NORTHERN EDWARDS PLATEAU AND THE NORTHWEST HILL COUNTRY. THE
SECOND WAS THE COLD FRONT...PUSHING SOUTH THROUGH THE CONCHO VALLEY AND
HEARTLAND. AS OF 02Z...COLD FRONT SEEMED TO EXTEND FROM SOUTH OF SAN ANGELO
NORTHEAST TO SOUTH OF DFW.

FRONT LIKELY TO CONTINUE MAKING PROGRESS FOR A FEW MORE HOURS...BEFORE
BEGINNING TO STALL. QUESTION IS WHERE. AT THIS POINT...STALLING SOMEWHERE
ACROSS THE SOUTHERN TIER OF COUNTIES APPEARS MOST LIKELY...WITH CONVECTION
PICKING UP EVEN MORE AS THE LOW LEVEL JET BECOMES A LITTLE STRONGER TONIGHT.
WILL CONTINUE THE FLASH FLOOD WATCH AND THE LIKELY POPS FOR THE NORTHERN
EDWARDS PLATEAU...NORTHWEST HILL COUNTRY...AND SOUTHERN HEARTLAND.

ELSEWHERE...NOT SEEING AS MUCH CONVECTION ACROSS EASTERN NEW MEXICO AS
THOUGHT MIGHT HAPPEN. MAY LATER AS ANOTHER SHORTWAVE EVIDENT ON WATER VAPOR
IMAGERY MOVES INTO THE AREA...BUT WILL HAVE A HARD TIME REACHING THE BIG
COUNTRY BEFORE SUNRISE. WILL GO AHEAD AND TRIM POPS BACK JUST A TAD.
