AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
328 PM CDT SUN AUG 2 2009

.DISCUSSION...
FEWER CLOUDS TODAY HAS ALLOWED TEMPERATURES TO CLIMB TODAY. SOUTHERLY
WINDS ARE TAPPING MOIST AIR AND SENDING DEWPOINTS UPWARD AS WELL.
ADDING TO THE MIX IS A DEEPENING SURFACE TROUGH OVER WHICH A LOW
LEVEL JET IS SETTING UP FOR THIS EVENING. THE BEST AREA FOR ANY
SEVERE STORMS TO INITIATE WILL BE IN THE WESTERN PORTIONS OF THE
PANHANDLES ALTHOUGH COVERAGE MAY BE LESS THAN IN PREVIOUS DAYS.

FEW CHANGES WERE MADE TO THE FORECAST PACKAGE. TEMPERATURES WILL BE
TRENDING UPWARD EARLY THIS WEEK AS THE SOILS DRY AND THE UPPER HIGH IS
PRESSED EASTWARD BY A STRONG WEST COAST SYSTEM. DISTURBANCES WILL
CONTINUE TO RIDE OVER THE RIDGE AND BRING THE CHANCES OF PRECIPITATION
THROUGH MIDWEEK. THE COVERAGE OF THE STORMS WILL DECREASE AS THE
NORTHWEST FLOW WEAKENS AND SUBSIDING AIR INTENSIFIES. THE BEST
CHANCES FOR ANY PRECIPITATION APPEARS TO BE IN THE OKLAHOMA AND
NORTHERN TEXAS PANHANDLE AS A SURFACE BOUNDARIES REMAINS STALLED OVER
KANSAS AND DISTURBANCES ROLL PAST THE AREA ALONG THE STATIONARY FRONT.

THE GENERAL FLOW WILL BE SHIFTING TO THE SOUTHWEST AS THE HIGH
CENTERS FURTHER TO THE EAST BY THE END OF THE WEEK. AS THE RIDGE
MOVES FURTHER EASTWARD AND THE WEST COAST TROUGH SETS UP...THIS WILL
ALLOW TEMPERATURES TO LOWER A BIT LATE IN THE WEEK.

THE MAIN CHANGES TO THIS PACKAGE WERE MADE ON FIRST PERIOD POPS AND
QPF...WITH MINOR TWEAKS OTHERWISE.

WYNNE

&&

.FIRE WEATHER...
HIGH PRESSURE WILL INTENSIFY OVER THE PANHANDLES EARLY IN THE WEEK
AND WILL PUSH TEMPERATURES UP AND ALLOW THE GROUND SURFACE TO DRY
FROM THE RECENT RAINS. 20 FOOT WINDS REMAIN AROUND 10 TO 15 KTS
THROUGH THE WEEK WHILE THE MINIMUM AFTERNOON RH READING ARE EXPECTED
TO CONTINUE AT 20 PERCENT OR HIGHER. NEXT WEEKEND...CONDITIONS SHOULD
BE DRIER AND WINDS MAY BE STRONGER AS A STRONG SURFACE SYSTEM SETS UP
IN THE LEE OF THE ROCKIES.
