EASTERN PART OF ELLIS COUNTY...GENERALLY EAST OF A FERRIS TO ENNIS 
LINE. THE ELLIS COUNTY SHERIFFS OFFICE REPORTED THAT BOTH THE NORTH

Area forecast discussion, Jun 17, 11:52 AM CDT, 1 hour 32 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE FORT WORTH TX
1152 AM CDT SUN JUN 17 2007

.AVIATION...
WEAK UPPER LOW 60S KCDS WILL CONTINUE TO CIRCULATE CONVECTION ACROSS
NTX TAF SITES THIS AFTERNOON....HOWEVER KACT MAY FAIR BETTER THAN
SITES WITHIN THE KDFW TRACON. A BAND OF SHRA/ISOLD TSRA AROUND KACT
WILL SPREAD OVER KDFW TRACON EARLY AFTERNOON. SCTD SHRA/TSRA
POSSIBLE REST OF THE AFTERNOON DUE TO UNSTABLE AIRMASS/HEATING AND
LIFT. THE UPPER LOW SHOULD BEGIN TO DRIFT NORTHEAST ON MONDAY WITH A
TREND TOWARD LESS CONVECTION.

CIGS ALREADY IMPROVING ACROSS KDFW TRACON...WHICH WE EXPECT TO HOLD
AS PREVAILING MOST OF THE AFTERNOON AND EARLY EVENING. HOWEVER...THE
VFR CIGS ARE CONTINGENT UPON DEVELOPMENT AND MOVEMENT OF
AFTERNOON/EVENING SHRA/TSRA.

CIGS BECOMING MVFR AGAIN TONIGHT...ESPECIALLY WHERE PRECIPITATION
OCCURS. A BRIEF EPISODE OF IFR CIGS/VIS POSSIBLE DURING INTENSE
DOWNPOURS.  75

PREV DISCUSSION... /ISSUED 1133 AM CDT SUN JUN 17 2007/
UPDATE...
UPDATED TO LOWER TEMPS SOME...NAMELY NRN 1/2 OF CWA. DRY SLOT COMING
UP FROM HILL COUNTRY AND UP INTO LAMPASAS/GOLDTHWAITE/HAMILTON AREAS
SHOULD GRADUALLY GIVE WAY TO SOME PARTIAL CLEARING AND WARMER TEMPS
FAR S/SW COUNTIES AND LESS RAINFALL BY AFTN. EAST OF I-35 SHOULD
REMAIN THE WETTEST. HAVE UPDATE TONIGHT FORECAST TO EXTEND THROUGH
THE NIGHT...AS UPPER LOW NEAR ABILENE AREA DRIFTS SLOWLY NEWD NEXT
12-24 HRS. PER HPC/NCEP QPF AND EXCESSIVE RAINFALL RISK...MAY NEED
TO EXTEND FFA (FLASH FLOOD WATCH) INTO TONIGHT FOR NAMELY THE NE 1/2
OF N TX...INCLUDING THE D/FW METRO. BELL/MCLENNAN COUNTIES WILL BE
CLOSE. UPDATE ALREADY SENT.

PREV DISCUSSION... /ISSUED 908 AM CDT SUN JUN 17 2007/
UPDATE...
HAVE UPDATED POPS TO CATEGORICAL/100% ALL COUNTIES THROUGH
NOON...THEN CATEGORICAL FAR E COUNTIES...LIKELY I-35 CORRIDOR AND
CHANCE POPS WEST PER LATEST ISENTROPIC LIFT AND UPPER DIFFLUENCE
PROGS. HOWEVER...AS IS THE CASE WITH THESE HYBRID/TROPICAL-LIKE
WARM CORE-WEAK COLD CORE SYSTEMS...MIXING TENDS TO BAND ACTIVITY
IN A MORE SCT NATURE IN THE PM HOURS...WITH MORE CONCENTRATED
ACTIVITY AT NIGHT WITH FORCING NEAR CIRCULATION AND SOME WEAK LLJ
TO THE E OF SUCH WEAK UPPER LOWS. ANOTHER UPDATE MAY BE NEEDED TO
TONE THINGS DOWN THIS AFTN...BUT FOR NOW...WILL WORK WITH WHAT
MODELS...RADAR/SATELLITE/ AND NCEP/HPC ARE INDICATING FOR TRENDS.
UPDATE OUT ALREADY.

PREV DISCUSSION... /ISSUED 325 AM CDT SUN JUN 17 2007/
DISCUSSION...
THE RAINY SAGA WILL CONTINUE TODAY AS THE UPPER LOW BEGINS TO
MEANDER ALONG THE RED RIVER. VORT LOBES ALONG THE PERIPHERY OF
THE UPPER LOW WILL ROTATE INTO EAST TEXAS...TRIGGERING MORE
SHOWERS AND THUNDERSTORMS THIS AFTERNOON. THUS FAR...RAINFALL
TOTALS ACROSS THE CWA HAVE NOT BEEN REMARKABLE. HOWEVER...RAINS
OVER THE PAST COUPLE OF DAYS HAVE SUFFICIENTLY SATURATED SOILS AND
CONVECTIVE RAINFALL RATES HAVE AVERAGED 1 INCH PER HOUR /OR
GREATER/ IN MANY LOCATIONS. WITH LITTLE CHANGE TO THE MOISTURE
CONTENT OF THE COLUMN /PWATS OVER 120 PERCENT OF NORMAL/ AND AREAS
OF LIFT CONTINUING OVER THE REGION...HEAVY RAINFALL AND THE
POTENTIAL FOR FLASH FLOODING WILL CONTINUE TO BE A THREAT TODAY.
THEREFORE...WILL CONTINUE THE FLASH FLOOD WATCH THROUGH THIS
AFTERNOON.

PRECIP CHANCES WILL TAPER OFF FROM WEST TO EAST MON AND TUES AS
THE UPPER LOW GRADUALLY LIFTS OUT INTO THE MID MISSISSIPPI VALLEY.

BY MID WEEK...WEAK UPPER HIGH WILL SET UP TO OUR WEST. DEEP
MOISTURE WILL REMAIN IN PLACE ACROSS THE REGION...WITH PWATS
OF 1.5 INCHES OR MORE IN A WEAKLY CAPPED ENVIRONMENT. SCATTERED
AFTERNOON PULSE THUNDERSTORMS WILL BE POSSIBLE WED...THURS...
FRI...AND SAT. AT THIS TIME...AREAS EAST OF I-35 APPEAR TO BE
FAVORED FOR T-STORM DEVELOPMENT WED/THURS AFTERNOON...AND FARTHER
WEST ON FRI AND SAT. HOWEVER...STILL QUITE A BIT OF UNCERTAINTY IN
THE FORECAST FOR THESE PERIODS.

TEMP WISE...HIGHS WILL BE TRENDING UPWARD OVER THE NEXT 7 DAYS.
STAYED CLOSE TO MEX NUMBERS FOR THE EXTENDED...ALTHOUGH CLOUD
COVER ASSOCIATED WITH SCATTERED CONVECTION WILL PLAY A ROLE IN
HIGHS MID WEEK THRU NEXT WEEKEND.

THANKS SHV AND HGX FOR COLLABORATION THIS MORNING.  SCHULTZ
