.AVIATION...
A SECONDARY COLD FRONT CONTINUES TO BARREL TO THE SOUTHEAST
ACROSS WEST TX AT THIS TIME...CURRENTLY LOCATED FROM NEAR
CHILDRESS...TO JAYTON...TO ANDREWS. THIS FRONT HAS BEEN MOVING
SOUTHEAST AT AROUND 40 KTS AND WILL SERVE AS A FOCUS FOR SHOWERS
AND THUNDERSTORMS ONCE IT ENCOUNTERS THE MOIST AIR TO THE EAST OF
THE DRYLINE. CONVECTION IS EXPECTED IN THE VICINITY OF EACH
TERMINAL....ALTHOUGH CONFIDENCE IS A BIT LOWER THAT DIRECT IMPACTS
WILL BE FELT AT KSJT AND KSOA.

LOW CLOUDS HAVE ALREADY SET IN AT KJCT AND KBBD AND ARE EXPECTED
TO AFFECT KSOA SHORTLY. THIS CLOUDS WILL GENERALLY REMAIN IN THE
LOW END MVFR CATEGORY BUT WILL BOUNCE AROUND A BIT ONCE THE
CONVECTIVE LINE ARRIVES. AS THIS LINE MARCHES EAST...WE WILL SEE
TEMPO MVFR TO IFR CONDITIONS...GIVING WAY TO CLEARING SKIES AFTER
SUNRISE. VFR CONDITIONS ARE ANTICIPATED THROUGHOUT THE DAY
THURSDAY AND INTO THE EVENING HOURS.

DISCUSSION...
SEE THE 00Z AVIATION DISCUSSION BELOW.

AVIATION...
ISOLATED CONVECTION WILL BE POSSIBLE THIS EVENING...MAINLY ACROSS
THE BIG COUNTRY. I DID INCLUDE A VCTS AT KABI TO ACCOUNT FOR THE
DEVELOPING CONVECTION TO THE WEST FOR THE NEXT FEW HOURS. FARTHER
SOUTH...WE WILL SEE A STRONGER CAP WHICH SHOULD PREVENT CONVECTIVE
INITIATION. AROUND 05Z IS WHEN THE FORECAST BECOMES MORE
INTERESTING. LOW CLOUDS ARE EXPECTED TO DEVELOP OVER THE SOUTHERN
TERMINALS...GENERALLY IN THE MVFR CATEGORY. A STRONG COLD FRONT
WILL BE OVERTAKING THE DRYLINE...MOVING SOUTH ACROSS THE AREA
AFTER 05Z. THIS WILL REACH KABI LIKELY BY 06Z...KSJT AROUND 08Z
AND KJCT BY 09Z.

THUNDERSTORMS ARE EXPECTED TO DEVELOP RAPIDLY ALONG THIS FRONT AS
IT ENCOUNTERS RICH MOISTURE AND INTERACTS WITH THE LOW LEVEL JET.
CONFIDENCE OF THUNDER AT THE TERMINAL IS LOWEST AT KSJT/KSOA WHERE
ONLY VCTS GROUPS WERE APPENDED. I DID INCLUDE 2-3 HOURS OF
PREVAILING CONVECTION AT THE OTHER SITES BUT IT WILL LIKELY BE
MORE LIKE 1-2. THIS FRONT WILL SCOUR THE LOW CIGS...RESULTING IN
PREVAILING VFR CONDITIONS AFTER 12Z THURSDAY MORNING.

JOHNSON

PREV DISCUSSION... /ISSUED 304 PM CDT WED APR 17 2013/

SHORT TERM...
CHANCES FOR RAIN WILL RETURN TO WEST CENTRAL TEXAS THIS EVENING.
SOME OF THE MESOSCALE MODELS ARE INDICATING SOME DEVELOPMENT THIS
AFTERNOON...BUT THE BETTER FORCING AND DYNAMICS LOOKS TO BE LATER
THIS EVENING...AS THE FRONT MOVES THROUGH THE AREA. MAINLY LOOKING
FOR IT TO BE THROUGH ABILENE BY 06Z AND THROUGH SAN ANGELO BY 09Z.
HAVE GONE WITH THE NAM SOLUTION ON TIMING...BECAUSE IT HANDLED THE
FRONT AT 15Z BETTER. LOW LEVEL MOISTURE WILL BE AMPLE IN THE WARM
SECTOR. AHEAD OF THE FRONT... WINDS STILL REMAINED OUT OF THE
SOUTH AT 15 TO 20 MPH. THERE IS A SLIGHTLY STRONGER CAP IN
PLACE...AND THE NAM WAS HINTING AT THE CAP STAYING INTACT FOR SOME
TIME. FORECAST CIN VALUES REMAINED IN THE 80 TO 100 J/KG RANGE.
THE 0-1 KM SHEAR IS VERY GOOD...GENERALLY IN THE 20 TO 30 KTS
RANGE. THE 0-6 KM SHEAR IS MODERATE...IN THE 40 TO 45 KTS RANGE
ACROSS THE CWA. THERE IS A 25H JET STREAK THAT WILL MOVE JUST
NORTH OF THE CWA...BUT THIS WILL PLACE THE CWA IN THE RIGHT EXIT
REGION OF THE JET WHICH IS NOT IDEAL. THE ALONG-BOUNDARY SHEAR
VECTORS MAKE IT MORE LIKELY THAT THE STORM MODE WILL BE MORE OF A
QLCS MODE. THE MAIN THREATS LOOK TO MAINLY BE HAIL AND WINDS..BUT
GIVEN THE LOW LEVEL SHEAR...I WOULD NOT RULE OUT AN ISOLATED
TORNADO. MOST OF THE ACTIVITY LOOKS TO BE LATER...POSSIBLY NOT
UNTIL AFTER MIDNIGHT. OTHERWISE...BEHIND THE COLD
FRONT...TEMPERATURES WILL RAPIDLY DROP IN THE 40S ACROSS MUCH OF
THE AREA BY 12Z TOMORROW. WINDS WILL BE STRONG OUT OF THE NORTH AT
15 TO 25 MPH...WITH GUSTS TO AT LEAST 25 MPH JUST AFTER THE
FRONTAL PASSAGE. TEMPERATURES WILL NOT BE AS WARM TOMORROW WITH
HIGHS...ONLY REACHING INTO UPPER 50S ACROSS THE BIG COUNTRY...WITH
70S ALONG INTERSTATE 10.

REIMER

LONG TERM...
THE MAIN STORY IN THE EXTENDED FORECAST IS THE POSSIBILITY OF
FREEZING OR NEAR FREEZING TEMPERATURES FRIDAY MORNING. AN
UNSEASONABLY COLD AIRMASS WILL BE IN PLACE ACROSS WEST CENTRAL
TEXAS THURSDAY NIGHT/FRIDAY MORNING. A 1029MB SURFACE HIGH WILL
STEADILY BUILD INTO THE AREA FROM THE NORTHWEST...RESULTING IN
LIGHT AND VARIABLE WINDS. DEWPOINT TEMPERATURES WILL BE IN THE
LOWER TO MID 20S...AND WILL COMBINE WITH MOSTLY CLEAR SKIES AND
LIGHT AND VARIABLE WINDS TO RESULT IN IDEAL RADIATIONAL COOLING
CONDITIONS. LOW TEMPERATURES WILL DROP INTO THE LOW TO MID
30S...WITH THE COOLEST READINGS EXPECTED ACROSS LOW LYING RIVER
VALLEYS. A FEW LOCATIONS COULD DROP TO NEAR OR BELOW
FREEZING...AND A FROST ADVISORY OR FREEZE WARNING MAY EVENTUALLY
BE NEEDED FOR PORTIONS OF WEST CENTRAL TEXAS. A PLEASANT DAY IS
FORECAST ON FRIDAY...WITH HIGHS IN THE MID TO UPPER 60S. SURFACE
HIGH PRESSURE WILL SHIFT EAST FRIDAY AFTERNOON...WITH WINDS
BECOMING LIGHT OUT OF THE SOUTHEAST BY EARLY EVENING. THE COLDEST
TEMPERATURES SATURDAY MORNING WILL LIKELY BE ACROSS OUR EAST AND
SOUTHEAST COUNTIES...CLOSER TO THE SURFACE HIGH.

A STEADY WARM UP WILL ENSUE THROUGH THE WEEKEND WITH HIGHS BACK
INTO THE MID AND UPPER 70S SATURDAY...AND INTO THE LOWER TO MID
80S ON SUNDAY AND MONDAY. THE NEXT LARGE UPPER LEVEL TROUGH WILL
DIVE OUT OF SOUTHWEST CANADA LATE SUNDAY...THEN TOWARD THE
CENTRAL/SOUTHERN PLAINS ON TUESDAY. MODELS ARE IN FAIRLY GOOD
AGREEMENT IN THIS SOLUTION...WHICH SENDS A STRONG COLD FRONT
THROUGH WEST CENTRAL TEXAS DURING THE DAY TUESDAY. THE EXACT
TIMING AND STRENGTH OF THIS FRONT IS SUBJECT TO CHANGE OVER THE
NEXT FEW DAYS...BUT I WENT AHEAD AND COOLED TEMPERATURES ACROSS
THE NORTHERN HALF OF THE AREA TUESDAY...AS THE FRONT MOVES
THROUGH. I ALSO COOLED OVERNIGHT LOWS WEDNESDAY MORNING AND
DAYTIME HIGHS ON WEDNESDAY AS COLD AIR ADVECTION CONTINUES.
SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE ALONG THE
FRONT...ESPECIALLY ACROSS THE EASTERN HALF OF THE REGION...BUT I
WOULD LIKE TO SEE A BIT MORE MODEL CONSISTENCY BEFORE INTRODUCING
POPS.
