AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
303 PM CDT SUN JUN 20 2004

.DISCUSSION...
STORMS STARTING TO GO NEAR METRO AMARILLO...SO DISCUSSION WILL BE
BRIEF.  EXPECT TO SEE STORMS INCREASE IN AREAL COVERAGE ACROSS THE
CENTRAL TX PNHDL THIS AFTERNOON WITH HIGH INSTABILITIES AND THE
OUTFLOW BOUNDARY FROM THE MCS THAT MOVED OVER KS/OK IN THE AREA.
BOUNDARY COULD PROVIDE ENOUGH FOCUS FOR LOW LEVEL VORTICITY THAT
DEVELOPMENT OF FUNNEL CLOUDS WITH RAPIDLY DEVELOPING STORMS IS
POSSIBLE. ALREADY HAVE HAD SOME REPORTS OF THIS ON FIRST STORM THAT
WENT UP...SO LANDSPOUTS WITH STORMS ALONG THE BOUNDARY COULD BE A
PROBLEM EARLY ON AND THEN DIMINISH THROUGH THE AFTERNOON. THESE
STORMS SHOULD CONTINUE INTO THE EVENING HOURS...THUS HAVE BUMPED UP
POPS TO LIKELY ACROSS THE CENTRAL AND WESTERN PARTS OF THE PNHDL.

FOLLOWED THE ETA FOR SHORT TERM AS IT HAS SLOWED DOWN PASSAGE OF THE
FRONT TO DURING THE DAY MONDAY.  THIS WILL HAVE TO BE WATCHED TO
SEE IF CONVECTIVE OUTFLOW WILL AID IN PUSHING THE FRONT THROUGH
EARLIER THAN EXPECTED.  REGARDLESS...EASTERLY UPSLOPE FLOW WILL
PERSIST INTO THE MIDDLE OF THE WEEK PROVIDING CHANCES FOR PRECIP
EVERY DAY.  PROBABLY WILL SEE STORMS FIRE IN THE MTNS OF CO/NM AND
THEN ROLL TOWARDS THE AREA LATE IN THE DAY INTO THE OVERNIGHT
HOURS.  MONDAY NIGHT INTO TUESDAY APPEARS TO HAVE A GOOD SHOT OF AN
MCS DEVELOPING AND ROLLING ACROSS THE REGION OVERNIGHT.  ALL-IN-
ALL...GRIDS/FCST LOOK GOOD FOR SHORT TERM.

LONG TERM GRIDS BEYOND WEDNESDAY WERE LEFT ALONE AS THEY APPEAR IN
GOOD SHAPE.  MODELS STILL SHOWING A GOOD CHANCE AT NORTHWEST FLOW
THROUGH THE PERIOD WHICH TRANSLATES INTO BELOW NORMAL TEMPS AND
CHANCES FOR PRECIP.
