ACROSS MEDINA...BEXAR...COMAL...KENDALL AND BANDERA COUNTIES OVER
THE NEXT FEW HOURS. THIS CONTINUES TO BE A VERY DANGEROUS FLOODING
SITUATION.

&&

.PREV DISCUSSION... /ISSUED 1020 AM CDT THU JUN 28 2007/

UPDATE...
CELL MERGERS GENERATING TORRENTIAL RAINFALL ALONG THE BALCONES
ESCARPMENT FROM MEDINA COUNTY NORTHEASTWARD TO BURNET COUNTY. THE
AREA OF RAINFALL IS SHOWING LITTLE MOVEMENT. DURING THE NEXT
COUPLE OF HOURS THE GREATEST THREAT OF FLASH FLOODING WILL BE
ACROSS NORTHEAST MEDINA COUNTY...EASTERN BANDERA COUNTY
AND NORTHWEST BEXAR COUNTY NORTHWARD ACROSS KENDALL... BLANCO...
EASTERN LLANO AND BURNET COUNTIES. THIS CONTINUES TO BE A VERY
DANGEROUS FLOODING SITUATION. CURRENT FCST LOOKS GOOD...NO
ADDITIONAL CHANGES ATTM.

PREV DISCUSSION... /ISSUED 844 AM CDT THU JUN 28 2007/

UPDATE...
HAVE DONE A QUICK UPDATE TO INCREASE POPS AND SKY COVER BASED ON
CURRENT AND ANTICIPATED RADAR AND SATELLITE TRENDS. OF GREAT
CONCERN WILL BE THE MERGER OF TWO CONVECTIVE COMPLEXES ACROSS THE
EASTERN HILL COUNTRY. REMEMBER THAT BOUNDARY MERGERS RESULTED IN
THE MARBLE FALLS/BURNET COUNTY RAIN/FLOOD EVENT. THIS IS A VERY
DANGEROUS FLOODING SITUATION.

PLEASE REMAIN ALERT TO THIS ONGOING DANGEROUS WEATHER SITUATION.
IT IS NEVER TOO EARLY TO MAKE PLANS IN CASE OF AN EMERGENCY.

PREV DISCUSSION... /ISSUED 608 AM CDT THU JUN 28 2007/

UPDATE...

QUICK UPDATE TO FORECAST PACKAGE TO EXTEND THE FLASH FLOOD WATCH
UNTIL 7 PM CDT THIS EVENING.

PREV DISCUSSION... /ISSUED 528 AM CDT THU JUN 28 2007/

AVIATION...
CIGS 1 THSD TO 3 THSD FT BKN WILL PREVAIL THRU 17Z WITH
SCT SHRA AND TSRA. CIGS 3 THSD TO 6 THSD BKN ARE FORECAST
AFTER 17Z WITH AREAS OF CIGS 1 THSD TO 2 THSD OVC AND
VSBYS 1 TO 3 MILES IN RAIN WITH SHOWERS AND THUNDERSTORMS.
CONDITIONS ARE FORECAST TO BECOME 5 THSD SCT CIGS ABOVE 10
THSD FT AFTER 23Z WITH SCT SHRA AND TSRA.  BY 05Z CIGS

AGAIN.

PREV DISCUSSION... /ISSUED 321 AM CDT THU JUN 28 2007/

DANGEROUSLY WET PATTERN WILL CONTINUE ACROSS SOUTH CENTRAL TEXAS
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK...

DISCUSSION...
ONE OF THE MOST DIFFICULT THINGS ABOUT THIS FORECAST PACKAGE WAS TRYING
TO COME UP WITH A NEW WAY TO EMPHASIZE JUST HOW WET...AND DANGEROUS...THE
WEATHER PATTERN CONTINUES TO BE. TROPICAL AIRMASS WILL CONTINUE TO SIT
OVER SOUTH CENTRAL TEXAS THROUGH THE NEXT SEVERAL DAYS. INSTABILITY
AND WEAK CIRCULATIONS ALOFT WILL PROVIDE THE FOCUS FOR SHOWERS AND
THUNDERSTORMS EACH DAY THROUGH AT LEAST THE BEGINNING OF NEXT WEEK.
UNORGANIZED CONVECTION WILL IGNITE ACROSS THE REGION TODAY AND FRIDAY.
THIS UNFORTUNATELY MEANS THAT EXACT LOCATIONS OF THE EXPECTED FLASH
FLOODING CAN NOT BE PINPOINTED. HOWEVER...SINCE GROUNDS ACROSS THE
ENTIRE CWA ARE ALREADY SATURATED...ANY ADDITIONAL RAINFALL COULD LEAD
TO FLASH FLOODING. THE FLASH FLOOD WATCH CURRENTLY IN EFFECT THROUGH
THIS MORNING WILL LIKELY BE EXTENDED.

THE MID-LEVEL SHEAR AXIS WILL SHIFT TO THE WEST LATE FRIDAY AND
SATURDAY...AND THE BEST RAIN CHANCES WILL THUS BE CENTERED ACROSS
THE RIO GRANDE PLAINS DURING THIS TIME FRAME. FOR THE REST OF THE
FORECAST PERIOD...BEST RAIN CHANCES WILL GENERALLY BE ACROSS THE
EASTERN HALF OF THE CWA AS INSTABILITY FROM DIURNAL HEATING AND SEA
BREEZE BOUNDARIES WILL PROVIDE FOCUS FOR CONVECTION.

DAYTIME HIGHS WILL CONTINUE TO BE LOWER THAN NORMAL AS EXPANSIVE
CLOUD COVERAGE WILL LIMIT SUNSHINE AND HEATING. HAVE GENERALLY
GONE WITH GFS NUMBERS AS IT FINALLY SEEMS TO HAVE A GRASP ON THE
SCENARIO.

PLEASE REMAIN ALERT TO THE ONGOING DANGEROUS WEATHER SITUATION. IT
IS NEVER TOO EARLY TO MAKE PLANS IN CASE OF AN EMERGENCY.
