AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
315 PM CDT WED APR 20 2005

.DISCUSSION...
DRYLINE HAS PUSHED ACROSS ALL BUT THE SOUTHEASTERN CORNER OF THE
TEXAS PANHANDLE. S/W MOVING ACROSS SW TEXAS IS HELPING TO GET
CONVECTION GOING ACROSS THE SOUTH PLAINS AND BEARS WATCHING TO SEE
IF THIS ACTIVITY WILL INCREASE IN STRENGTH AND COVERAGE ACROSS THE
FAR SOUTHEAST THIS EVENING.  FOR THE REST OF THE REGION...DRY AIR
IS ENTRENCHED BEHIND THE DRYLINE AND WILL KEEP CLEAR SKIES IN
PLACE.  ONLY MAJOR CHANGE TO SHORT TERM GRIDS WAS TO PULL POP
CHANCES OUT FOR TOMORROW AS DRY AIR REMAINS IN PLACE OVER THE
REGION.  WINDSHIFT WILL PUSH THROUGH DURING THE DAY TOMORROW...BUT
HIGHER DEWPTS BEHIND THE FRONT WILL DO LITTLE TO GET PRECIP GOING
AS TIME SERIES SHOW LITTLE MOISTURE ALOFT AND WEAK SYNOPTIC LIFT.
TEMPS WILL BE A BIT COOLER BUT NOT BY MUCH AS FLOW PATTERN ALOFT
STARTS TO TRANSITION TO A S/W RIDGE BY THE WEEKEND.

AS THE FLOW TRANSITIONS...A SECONDARY SURGE OF COOL AIR WILL SLIDE
ACROSS THE REGION LATE THURSDAY/DURING THE DAY FRIDAY.  ALSO PUT
WINDS INTO THE HIGH-END OF BREEZY FOR FRIDAY AS SFC PRES GRADIENT
TIGHTENS UP BEHIND FRONTAL PASSAGE.  THIS WILL THEN LET MUCH COOLER
AIR SPILL INTO THE PANHANDLES AND KNOCK TEMPS BACK INTO THE FIRST
PART OF THE WEEK.  SHOULD SEE DRY FRONTAL PASSAGE AS ATMOSPHERE WILL
BE RELATIVELY DRY.  AS RIDGE MOVES EAST OF AREA LATE SUNDAY...
RETURN FLOW SHOULD BECOME ESTABLISHED AND TEMPS BEGIN TO MODERATE.
COULD ALSO SEE MOISTURE START TO RETURN TO THE REGION BUT STILL NOT
CONFIDENT ON TIMING SO LEFT POP STRUCTURE ALONE.  DID BUMP TEMPS UP
A CATEGORY FOR MON AND TUE.  MODELS ADVERTISE ANOTHER FRONT PUSHING
THROUGH THE REGION TUESDAY...BUT WILL WAIT AND SEE HOW THINGS
UNFOLD NEXT WEEK BEFORE MAKING MAJOR CHANGES.
