.AVIATION...
WIDELY SCATTERED SHOWERS AND THUNDERSTORMS THIS EVENING WILL
DISSIPATE BY 03Z. CARRYING VICINITY THUNDERSTORM AT KSJT AND
KABI PER AREA RADARS...WITH KSJT LIKELY TO HAVE THE MOST DIRECT
IMPACTS. THUNDERSTORM HAZARDS THIS EVENING INCLUDE GUSTY
WINDS...OCCASIONAL LIGHTNING...BRIEF HEAVY RAIN AND PERHAPS SMALL
HAIL. A COLD FRONT WILL MOVE SOUTH ACROSS THE BIG COUNTRY EARLY
TONIGHT AND WILL BE SOUTH OF A BROWNWOOD TO OZONA LINE BY 12Z
MONDAY. THIS FRONT WILL SAG A LITTLE FARTHER SOUTH DURING THE DAY
MONDAY BEFORE STALLING JUST SOUTH OF THE INTERSTATE 10 CORRIDOR
MONDAY EVENING. SHOWERS AND THUNDERSTORMS SHOULD DEVELOP NEAR
AND NORTH OF THIS FRONTAL BOUNDARY BETWEEN 21Z MONDAY AND 00Z
TUESDAY. OUTSIDE OF CONVECTIVE ACTIVITY THIS EVENING...VFR
CONDITIONS WILL PREVAIL THROUGH MIDNIGHT WITH SCATTERED TO
BROKEN COVERAGE OF MIDDLE AND HIGH CLOUDS. PATCHY LOW CLOUD
DEVELOPMENT WITH MVFR BASES AND CEILINGS SHOULD DEVELOP LATE TONIGHT
ACROSS EASTERN AND SOUTHERN PARTS OF WEST CENTRAL TEXAS...
POSSIBLY AFFECTING THE KABI...KJCT AND KSOA TAF SITES. AN INCREASE
IN CLOUD COVERAGE IS EXPECTED ON MONDAY WITH VFR CEILINGS IN THE
RANGE OF 3K-6K FT. THE PRESENCE OF A STALLING DRYLINE AND OUTFLOW
BOUNDARIES AHEAD OF APPROACHING COLD FRONT WILL RESULT IN VARIABLE
WINDS EARLY TONIGHT. WINDS WILL SHIFT TO THE NORTH WITH PASSAGE
OF THE COLD FRONT. NORTH TO NORTHEAST WINDS ARE EXPECTED ACROSS
MUCH OF THE AREA ON MONDAY...WITH EAST-NORTHEAST WINDS CLOSER TO
THE INTERSTATE 10 CORRIDOR.

&&

.PREV DISCUSSION... /ISSUED 343 PM CDT SUN MAY 6 2012/

SHORT TERM...
DRYLINE HAS ENTERED WESTERN ZONES THIS AFTERNOON AND WILL MIX EAST
A BIT MORE THROUGH THE REST OF THE AFTERNOON HOURS. STILL LOOKING
AT THE POSSIBILITY OF THUNDERSTORM DEVELOPMENT EAST OF THE DRYLINE
ACROSS MAINLY THE HEARTLAND AND NORTHWEST HILL COUNTRY WHERE BETTER
LOW LEVEL MOISTURE EXISTS. TEMPERATURES ACROSS THIS AREA HAVE RISEN
INTO THE MID AND UPPER 90S WITH DEWPOINTS IN THE LOWER 60S. SPC MESO
ANALYSIS INDICATES LITTLE IF ANY CONVECTIVE INHIBITION WITHIN A
MODERATELY UNSTABLE AIRMASS. SOME SHALLOW CUMULIFORM CLOUDS ARE
BEGINNING TO DEVELOP ACROSS MASON COUNTY THIS PAST HOUR. MUCH LIKE
THE PAST COUPLE OF DAYS...ANY STORMS THAT DEVELOP WILL HAVE THE
POTENTIAL TO BECOME SEVERE...WITH LARGE HAIL AND DAMAGING WINDS
THE MAIN THREAT. LOCALLY HEAVY RAINFALL WILL ALSO BE
POSSIBLE.

A COLD FRONT WILL MOVE SOUTH ACROSS THE AREA TONIGHT...BRINGING
COOLER TEMPERATURES TO THE AREA FOR MONDAY. THE FRONT SHOULD ENTER
THE BIG COUNTRY BY EARLY EVENING...REACHING THE 1-10 CORRIDOR BY
DAYBREAK MONDAY. THE FRONT IS EXPECTED TO REMAIN NEARLY STATIONARY
ACROSS FAR SOUTHERN COUNTIES ON MONDAY. IT WILL BE NOTICEABLY COOLER
MONDAY...ESPECIALLY ACROSS CENTRAL AND NORTHERN ZONES WHERE HIGHS
WILL ONLY BE IN THE LOW TO MID 80S. UPPER 80S EXPECTED ALONG THE
I-10 CORRIDOR BUT A FEW LOWER 90S NOT OUT OF THE QUESTION SOUTH OF
WHERE THE FRONT STALLS. RAIN CHANCES WILL INCREASE LATE MONDAY
AFTERNOON AND ESPECIALLY MONDAY NIGHT AS LIFT INCREASES WITH THE
APPROACH OF AN UPPER LEVEL JET.

24

LONG TERM...
THE COLD FRONT SHOULD PROGRESS SOUTH OF THE CWA BY TOMORROW
EVENING AND BECOME STATIONARY OVER DEEP SOUTH TEXAS THROUGH THE
END OF THE WEEK. A CLOSED UPPER LOW WILL MOVE SOUTH OVER SOUTHERN
NEVADA BY TOMORROW EVENING BEFORE TURNING EAST...PASSING OVER THE
FORECAST AREA DURING THE DAY ON FRIDAY. THE OVERRUNNING NORTH OF
THE COLD FRONT THROUGH THE REMAINDER OF THE WEEK WILL RESULT IN
CLOUDY SKIES...COOLER TEMPERATURES AND A CONTINUOUS CHANCE OF
RAINFALL THROUGH FRIDAY. IN ADDITION...THE SOUTHWEST FLOW ALOFT
OVER THE FORECAST AREA RESULTING FROM THE PLACEMENT OF THE UPPER
LOW TO OUR WEST WILL BRING PERIODIC DISTURBANCES OVER THE AREA
THROUGH FRIDAY...INCREASING THE CHANCE OF RAINFALL EVEN MORE. AS
THE CENTER OF THE UPPER LOW FINALLY MOVES EAST OF THE CWA LATE
FRIDAY...OUR FAVORABLE RAINFALL CHANCES WILL COME TO AN END.
RAINFALL AMOUNTS OF 1 TO 2 INCHES ARE POSSIBLE THROUGH MID-WEEK
WITH LOCALLY HEAVIER AMOUNTS IN THE VICINITY OF THUNDERSTORMS.

THE COOLER THAN NORMAL TEMPERATURES EXPECTED THROUGH THE COMING
WEEK WILL RANGE FROM AFTERNOON HIGHS IN THE 70S TO LOWER 80S TO
MORNING LOWS IN THE 50S AND 60S. A DRY FORECAST IS ON TAP NEXT
WEEKEND IN THE WAKE OF THE EXITING UPPER LOW WITH AFTERNOON HIGHS
WARMING BACK INTO THE 80S.
