AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
618 AM CDT FRI AUG 17 2007

.AVIATION...
AVIATION FORECASTS WILL CONTINUE TO BE RATHER TRICKY THROUGH MUCH
OF THE DAY TODAY AS THE REMNANTS OF ERIN CONTINUES TO BRING HEAVY
RAIN BANDS ACROSS WEST CENTRAL TEXAS. WILL KEEP IFR CEILINGS AND
LOW VISIBILITIES DUE TO HEAVY RAIN ACROSS SONORA... JUNCTION...
BRADY AND SAN ANGELO AIRPORTS. ABILENE AREA WILL START OUT A BIT
DRIER THIS MORNING...BUT WILL STILL HAVE A CHANCE FOR AFTERNOON
CONVECTION AS THE RAIN BANDS EXPAND OUTWARD DURING THE AFTERNOON.
WILL INTRODUCE THUNDER TO MOST TAF SITES FOR THE AFTERNOON AS RAIN
BANDS EXPAND OUTWARD. OVERNIGHT VISIBILITY AND CEILING FORECAST HIGHLY
DEPENDANT ON THE TRACK OF THE REMNANTS OF ERIN...WHICH SHOULD HEAD
SLOWLY WEST TO NORTHWEST TODAY. THIS WOULD PUT HEAVIEST RAIN
TONIGHT OVER FAR WESTERN COUNTIES...BUT WILL HAVE TO WATCH
CLOSELY.

.PREV DISCUSSION... /ISSUED 331 AM CDT FRI AUG 17 2007/

SHORT TERM...
CENTER OF THE REMNANTS OF TROPICAL STORM ERIN APPEARS JUST SOUTH
OF ROCK SPRINGS AT 230 AM...MOVING NORTHWEST AT AROUND 10 MPH.
HEAVIEST RAIN WAS MOVING FROM MASON AND KIMBLE COUNTIES...INTO
SUTTON AND SCHLEICHER COUNTIES. THE WERE A FEW BANDS MOVING INTO
SOUTHERN TOM GREEN COUNTY TOWARD SAN ANGELO. EXPECT INTENSIFICATION
OF RAIN BANDS NEAR THE LOW PRESSURE CENTER EARLY THIS MORNING.

HEAVIEST RAINFALL SHOULD BE IN THE CONCHO VALLEY AND SOUTHWARD TO
SUTTON AND CROCKETT COUNTIES THIS MORNING AND AFTERNOON. EXPECT
CONVECTIVE BANDS TO EXPAND OUTWARD IN THE AFTERNOON AND COULD
AFFECT THE BIG COUNTRY WITH LOCALLY HEAVY RAINFALL...BUT EXPECT
MOST OF THE FLOODING POTENTIAL TO BE SOUTH OF IT. ADDED STERLING
AND COKE COUNTIES TO THE FLASH FLOOD WATCH...WHICH EXPIRES AT 7 PM
CDT FRIDAY.

LONG TERM...
WRF MODEL IS SLOWER THAN THE NAM MODEL...BRINGING CENTER OF LOW
OVER CROCKETT COUNTY AT 1 PM TODAY...THEN DRIFTS IT NORTHWARD INTO THE
EASTERN PERMIAN BASIN/WESTERN CONCHO VALLEY OVERNIGHT. NAM TAKES
IT WESTWARD TOWARD THE BIG BEND. WRF MODEL SO FAR SEEMS TO BE
MORE ON TRACK (BUT SLOWER)...AND WILL USE ITS MOVEMENT AND DIRECTION
TODAY...BUT BEYOND THAT CONFIDENCE IS LOW...ESPECIALLY ON THE
DIRECTION. THE WRF MODEL TRIES TO DRIFT THE UPPER LOW...NORTHWARD
INTO THE COLORADO CITY/SNYDER SATURDAY MORNING...THEN PUSH IT
SLOWLY SOUTHWARD BACK TOWARD THE CONCHO VALLEY SUNDAY. THIS
PARTICULAR MOTION WOULD PUT A LOT OF WATER INTO THE CONCHO
VALLEY...WITH THE WRF MODEL PUTTING 8-11 INCHES OVER THE CONCHO
VALLEY NORTH TO ...5 INCHES NEAR SWEETWATER BY 7 AM SATURDAY...AND BY
MONDAY MORNING UP TO 15 INCHES. THAT ALL SAID...THE WRF MODEL HAS
NOT BEEN THAT ACCURATE RECENTLY...BUT PAST PERFORMANCE IS NOT
ALWAYS INDICATIVE OF PRESENT...AS THE STOCK FUNDS LIKE TO SAY.
BUT WILL HAVE TO REALLY WATCH ITS MOVEMENT TONIGHT.

LOTS OF SPECULATION OF TRACK OF HURRICANE DEAN. WRF MODEL HAS
REMNANTS MOVING UP THE LOWER GRANDE VALLEY...POSSIBLY AFFECTING
WEST CENTRAL TEXAS NEXT FRIDAY. THIS IS BEYOND CURRENT FORECAST
AND PROBABILITIES OF IT DOING EXACTLY THAT ARE LOW...BUT BEAR
WATCHING...ESPECIALLY AS AREAS OF WEST CENTRAL TEXAS MAY BE SATURATED.
