AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
1253 PM CDT FRI MAY 23 2008
.AVIATION...
WINDS TO PICK UP THIS AFTERNOON IN RESPONSE TO SURFACE PRESSURE

.PREV DISCUSSION... /ISSUED 1023 AM CDT FRI MAY 23 2008/
UPDATE...
AT 15Z...THE DRYLINE EXTENDED FROM NEAR KGUY TO JUST EAST OF KAMA
WITH MID/UPPER 60S DEWPOINTS ON THE MOIST SIDE OF THE BOUNDARY AND
DEWPOINTS IN THE 30S TO THE WEST. THE SURFACE LOW IS RATHER POORLY
ORGANIZED THIS MORNING...WITH THE TROF EXTENDING DOWN INTO THE
PANHANDLES...RESULTING IN RELATIVELY LIGHT WINDS. AS THE DAY
PROGRESSES...THE SURFACE LOW IS EXPECTED TO DEEPEN OVER EASTERN
COLORADO...CAUSING WINDS ACROSS THE PANHANDLE TO INCREASE. THIS WILL
HELP PUSH THE DRYLINE INTO THE EASTERN ZONES THIS AFTERNOON. HOW FAR
EAST THE DRYLINE PUSHES BEFORE STALLING IS THE BIG QUESTION. WITH THE
DEEPER MOISTURE OFF THE CAPROCK...I DO NOT ANTICIPATE THE DRYLINE
REACHING THE OK STATE LINE BY THE TIME CONVECTION INITIATES...BUT
THE GUIDANCE PROGS ARE SHOWING THIS BOUNDARY MIXING INTO OK.
HOWEVER...THE MODELS HAVE HAD AN EASTWARD BIAS WITH THE DRYLINE
POSITION EACH OF THE PAST FEW DAYS SO THAT IS NOTED. IF STORMS ARE
ABLE TO FIRE ALONG THE DRYLINE THIS AFTERNOON/EVENING...SOME STORMS
COULD BECOME SEVERE. THIS IS ADDRESSED IN THE FORECAST/HWO. THE MAIN
THREATS WITH ANY OF THESE STORMS APPEAR TO BE LARGE HAIL AND/OR
DAMAGING WINDS. THE DRYLINE WILL SLOSH BACK TO THE WEST THIS
EVENING...BUT WILL LIKELY STALL OUT OVER THE CENTRAL ZONES AFTER
MIDNIGHT. UPDATED FORECAST PRODUCTS ARE ON THE WAY.
