AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
909 PM CDT MON AUG 14 2006

.UPDATE...
BROKEN BAND OF THUNDERSTORMS STRETCHES FROM NEAR ENID EASTWARD
INTO WESTERN AR NEAR FORT SMITH. THIS ACTIVITY CONTINUES TO LIFT
NORTHEAST...WELL NORTH OF THE SYNOPTIC BOUNDARY THAT APPEARS TO
BE ACROSS SOUTHERN OK. HAVE SEEN A MARKED DECREASE IN INTENSITY
OVER THE PAST FEW HOURS AS THE BOUNDARY LAYER HAS BEGUN TO
COOL...BUT STILL COULD SEE SOME 40-50 MPH GUSTS ALONG THE LEADING
EDGE OF THE STORMS OVER THE NEXT SEVERAL HOURS. DESPITE THE
WEAKENING INSTABILITY...MESOSCALE BOUNDARY INTERACTIONS AND LIFT
ASSOCIATED WITH NORTHWARD MOVING UPPER SYSTEM OVER WRN TX COULD
KEEP SCATTERED CONVECTION GOING MUCH OF THE NIGHT.

GOING POPS LOOK PRETTY GOOD...BUT HAVE DECREASED POPS NEAR THE
RED RIVER...WITH BEST CHANCE POPS REMAINING ACROSS EAST CENTRAL
AND PARTS OF NORTHEAST OK.

UPDATED PRODUCTS WILL BE OUR AROUND 920 PM.

&&

.PREV DISCUSSION... (ISSUED 248 PM CDT MON AUG 14 2006)

DISCUSSION...
POPS FORECAST WILL BE SOMEWHAT TRICKY TONIGHT AS FRONTAL BOUNDARY
PRESENTLY FROM ABOUT A MIAMI TO PAWNEE LINE SAGS ACROSS PART OF THE
AREA DURING THE NIGHT. IN ADDITION...AN OUTFLOW BOUNDARY FROM
SOUTHERN KANSAS STORMS EARLY THIS MORNING REMAINS PRESENT
SOMEWHERE NEAR I-40. A FEW STORMS HAVE BEGUN TO FIRE ALONG THESE
TWO FEATURES AND SHOULD CONTINUE ON THROUGH THE EVENING. MODIFIED
MORNING SOUNDINGS INDICATE DEEP INVERTED-V STRUCTURE AND A FEW
STRONG OR DAMAGING DOWNBURSTS SEEM LIKELY THROUGH THE EVENING
HOURS...WITH BETTER CHANCES TO THE SOUTH AND EAST.

MEANWHILE A WELL DEFINED MCV CLEARLY SEEN ON VIS SATELLITE NEAR
ABILENE CONTINUES TO SLOWLY LIFT NORTH NORTHEAST. MODEL TRENDS
HAVE BEEN TO LIFT THIS FEATURE ALMOST DUE NORTH AND EVENTUALLY
SHEAR IT APART AS IT ENCOUNTERS THE FRONTAL ZONE ACROSS NW
OKLAHOMA. THIS FEATURE COULD SERVE TO ENHANCE CONVECTION ALONG
FRONT SHOULD IT MAINTAIN ITSELF LONG ENOUGH AND WILL THUS KEEP
MEDIUM TO HIGH CHANCE POPS GOING THROUGH THE NIGHT MOST AREAS.

FRONTAL POSITION AND POSSIBLE ONGOING CONVECTION EARLY MAKE FOR
TRICKY TEMP FORECAST TUESDAY. BOTH WRF/GFS FROM 12Z SUGGEST FRONT
WILL NOT CLEAR SE OKLAHOMA AND GIVEN UPPER FLOW PATTERN AND TIME
OF YEAR THIS SEEMS PLAUSIBLE...BUT IF CONVECTION BECOMES MORE
WIDESPREAD OUTFLOW COULD PUSH MUCH FURTHER SOUTH. HAVE STUCK WITH
IDEA OF GOING ABOVE GUIDANCE TEMPS WITH FAR SOUTHERN AREAS AGAIN
TOPPING 100.

RETURN FLOW SETS UP QUICKLY MIDWEEK AS FRONT WASHES OUT AND BRINGS
MORE HOT WEATHER. AGAIN HAVE GONE WELL ABOVE GUIDANCE TEMPS
THROUGH THE LATER PERIODS. STILL SOME POSSIBILITY OF ANOTHER
FRONTAL BOUNDARY APPROACHING FROM THE NORTH BY THE WEEKEND...BUT
FOR NOW HAVE KEPT HOT AND DRY FORECAST THROUGH DAY 7.
