AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
330 AM CDT MON APR 18 2016

POTENTIALLY SIGNIFICANT FLASH FLOOD AND RIVER FLOOD THREAT
CONTINUES DUE TO HEAVY RAIN TODAY THROUGH EARLY TUESDAY MORNING

.SHORT TERM (TODAY THROUGH TUESDAY)...
A SURFACE BOUNDARY (WEAK COLD FRONT) LINGERS ALONG THE ESCARPMENT
WEST OF I-35 AND NORTH OF HIGHWAY 90 WHILE AN UPPER LEVEL LOW
MEANDERS OVER THE FOUR CORNERS REGION. RADARS SHOW SHOWERS AND
THUNDERSTORMS FROM THE EASTERN HILL COUNTRY ACROSS I-35 INTO
SOUTHEASTERN TEXAS AND OVER THE RIO GRANDE PLAINS. EXPECT AREAS IN
BETWEEN TO FILL IN WITH SHOWERS AND THUNDERSTORMS EARLY THIS
MORNING AS WEAK SHORTWAVE MOVES FROM MEXICO INTO TEXAS. RAINFALL
INTENSITY WILL INCREASE AS STORMS TRAIN OVER THE SAME AREAS AND
THE LOW LEVEL JET IMPINGES ON THE SURFACE BOUNDARY ENHANCING LIFT
WITH PWS AT OR ABOVE 1.5 INCHES. THE HEAVY RAINFALL MAINTAINS THE
FLASH FLOOD AND RIVER FLOOD THREAT ACROSS MUCH OF SOUTH CENTRAL
TEXAS. SOME AREAS HAVE ALREADY HAD UP TO 9 INCHES OF RAIN AND THIS
HAS CAUSED SOME FLOODING ON A FEW RIVERS AND STREAMS. SOILS ARE
SATURATED AND RUNOFF WILL BECOME RAPID LEADING TO FLASH FLOODING
AND IN TURN RIVER FLOODING. THE GREATEST THREAT AREA IS ACROSS OUR
NORTHEASTERN COUNTIES FROM TRAVIS AND WILLIAMSON TO BASTROP...LEE
AND FAYETTE WHERE THE HEAVIEST RAINS HAVE FALLEN. WITH TIME...THE
SURFACE BOUNDARY SAGS SOUTH AND THE UPPER LEVEL TROUGH WEAKENS
WHILE ELONGATING EAST TO WEST OVER THE CENTRAL ROCKIES AND HIGH
PLAINS. SOME MODELS MAINTAIN A HEAVY RAIN THREAT TONIGHT INTO
EARLY TUESDAY ACROSS OUR EASTERN AREAS WHILE OTHERS END THE THREAT
BY THIS AFTERNOON. THUS...THE CONFIDENCE IS A LITTLE LOWER FOR
TONIGHT INTO EARLY TUESDAY. CAPES OF 1500 TO 2000 J/KG AND 0 TO 6
KM SHEAR OF 25 TO 35 KTS INDICATE A SLIGHT THREAT OF STRONG TO
SEVERE STORMS TODAY AND TUESDAY.

&&

.LONG TERM (TUESDAY NIGHT THROUGH SUNDAY)...
THE WEAKENING UPPER LEVEL LOW SLOWLY MOVES OUT INTO THE PLAINS MID
WEEK AS THE SURFACE BOUNDARY LINGERS. EXPECT ISOLATED TO SCATTERED
SHOWERS AND THUNDERSTORMS TUESDAY NIGHT THROUGH THURSDAY NIGHT.
CANNOT RULE OUT LOCALLY HEAVY RAINS AND ISOLATED STRONG TO SEVERE
STORMS. THE UPPER LEVEL LOW TRANSITIONS INTO A TROUGH MOVING
ACROSS THE MID WEST AND DRAGS A COLD FRONT ACROSS OUR AREA LATER
THIS WEEK ENDING THE RAINS...EXCEPT FOR SLIGHT CHANCES ALONG THE
RIO GRANDE PLAINS WHERE MOIST SOUTHEASTERLY FLOW PERSISTS FRIDAY
AND SATURDAY. RAIN CHANCES RETURN TO THE REST OF SOUTH CENTRAL
TEXAS ON SUNDAY AS ANOTHER UPPER LEVEL TROUGH APPROACHES.
