Area forecast discussion, Aug 8, 3:27 PM CDT, 2 hours 49 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
327 PM CDT FRI AUG 8 2014

.DISCUSSION...

VERY FEW CHANGES WERE MADE TO THE FORECAST. OFF AND ON RAIN CHANCES
WILL CONTINUE THROUGH THE NEXT WEEK AS A MID LEVEL MOISTURE PLUME WILL
CONTINUE TO RIDE ABOVE A WEAK TO MODERATELY UNSTABLE LOW LEVEL
AIRMASS. OVERALL UPR FORCING WILL BE WEAK, BUT IT IS THE GENERAL LACK
OF STRONG SUBSIDENCE THAT WILL ALLOW THE OFF AND ON SHOWERS AND
STORMS.

MED RANGE MODELS CONTINUE TO WAFFLE WRT HANDLING OF A SIGNIFICANT
AMOUNT OF MID/UPR ENERGY EXPECTED TO AFFECT THE NOAM UPR AIR PATTERN
NEXT WEEK. CHANGES WILL EVENTUALLY BE NEEDED TO NEXT WEEK'S FORECAST,
BUT AGAIN IT WILL TAKE BETTER AGREEMENT BEFORE PERIODS OF MORE LIKELY
PRECIP CAN BE DETERMINED.

ONE THING THAT LOOKS LIKE A GOOD BET IS THAT IT WON'T BE AS HOT NEXT
WEEK AS IT WAS FOR MUCH OF THIS WEEK.
