AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
320 PM CDT THU JUN 30 2005

.DISCUSSION...
COLD FRONT HAS BECOME STATIONARY SOUTHWEST TO NORTHEAST ACROSS THE
PANHANDLES THIS AFTERNOON. MID LEVEL SHORT WAVE MOVING NORTHEAST
FROM NORTHERN NEW MEXICO WILL COMBINE WITH MOISTURE CONVERGENCE
ALONG THE FRONT TO HELP PRODUCE THUNDERSTORMS TONIGHT. MID LEVEL
MOISTURE IS ALSO INCREASING ACROSS THE PANHANDLES FROM THE
SOUTHWEST. THIS MOISTURE IS IN A ZONE OF ELEVATED INSTABILITY WHICH
MAY ALSO HELP SPARK SOME CONVECTION. THUNDERSTORMS MAY HAVE A TOUGH
TIME GETTING INTO THE NORTHWEST ZONES BEHIND FRONT...AS MOUNTAIN
CONVECTION WOULD HAVE TO MAKE IT THAT FAR.

UPPER LEVEL RIDGE OVER THE SOUTHERN ROCKIES AND SOUTHERN PLAINS
WILL RETREAT A LITTLE THROUGH THE WEEKEND TO ALLOW SEVERAL SHORT
WAVES TO MOVE FROM THE ROCKIES ONTO THE PLAINS IN A ZONAL TO
SLIGHTLY NORTHWEST FLOW ALOFT.  RETURN FLOW BEHIND SURFACE COLD
FRONT SHOULD HELP TO INTENSIFY THE DIRECTIONAL SHEAR INTO THE
MOUNTAIN CONVECTION THAT IS EXPECTED TO DEVELOP FRIDAY AFTERNOON.
THESE STORMS SHOULD THEN MOVE EAST SOUTHEAST INTO THE PANHANDLES.
SEE SWODY2 AND HWOAMA FOR THE POSSIBILITY OF SEVERE STORMS ON
FRIDAY.

WENT AHEAD AND ADDED SOME LOW POPS TO THE NORTHWEST ZONES SATURDAY
NIGHT...ONCE AGAIN FOR MOUNTAIN CONVECTION MOVING THIS WAY ALONG
WITH ANOTHER SHORT WAVE.

ANOTHER COLD FRONT TRIES TO MAKE A RUN AT THE PANHANDLES ON MONDAY
MORNING. WILL HOLD OFF ON ANY POPS FOR NOW AS THE NORTHERN STREAM
WAVE ASSOCIATED WITH THIS NEXT FRONT IS WEAKER THAN THE CURRENT ONE
MOVING ACROSS THE WESTERN GREAT LAKES.

COULD ACTUALLY ADD SOME POPS AT LEAST TO THE NORTHWEST ZONES ALL
THE WAY THROUGH THE END OF NEXT WEEK.  UPPER HIGH STARTS TO BUILD
ACROSS THE 4-CORNERS REGION AND THE PANHANDLES GO BACK TO A TYPICAL
SUMMERTIME NORTHWEST FLOW REGIME.
