AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
330 PM CDT THU JUL 12 2012

.DISCUSSION...
A FEW POP UP SHOWERS OVER THE TERRAIN OF SOUTHEAST OK ARE ABOUT
ALL WE CAN MUSTER THIS AFTERNOON...AND THIS SHOULD BE GONE PRIOR
TO 00Z. ANOTHER WEAK DISTURBANCE IN NNW FLOW ALOFT CAN BE SEEN IN
WATER VAPOR AND HAS SPARKED A FEW THUNDERSTORMS ACROSS NE KANSAS.
THIS WILL NEED TO BE MONITORED THIS EVENING FOR POSSIBLE ISOLATED
DEVELOPMENT OVER FAR NE OKLAHOMA AND NW ARKANSAS...RIGHT NOW WILL
KEEP A DRY FORECAST FOR THE EVENING PERIOD.

OTHER THAN THAT NO MAJOR CHANGES ANTICIPATED THROUGH THE NEXT
SEVERAL DAYS WITH ANY PRECIP CHANCES TIED MAINLY TO TERRAIN
INFLUENCES AND ANY SHORTWAVE ENERGY THAT DROPS SOUTH ALONG THE
EASTERN SIDE OF THE UPPER RIDGE. WEAK UPPER TROUGH WILL GRADUALLY
PUSH WEST ACROSS TEXAS THIS WEEKEND AND SHOULD OFFER A BIT BETTER
CHANCES OF SHOWERS AND THUNDERSTORMS IN SOUTHEAST AREAS THIS
WEEKEND.

OTHERWISE...SUMMER DRONES ON. TEMPS LIKELY TO INCH UP
NEXT WEEK WITH AFTERNOON HEAT INDICES IN MANY AREAS NEAR OR A
LITTLE ABOVE 105...HOWEVER OUTSIDE OF URBAN LOCATIONS THE
OVERNIGHT TEMPS SHOULD REMAIN BELOW THE 75 DEGREE THRESHOLD FOR
HEAT ADVISORIES. MAV/MEX NUMBERS REMAIN SIGNIFICANTLY TOO COOL.
