AVIATION...
FOR THE 00Z TAFS...A VARIETY OF WEATHER IS EXPECTED AT THE TERMINAL
SITES DURING THE NEXT 24 HOURS. A FAST MOVING UPPER LEVEL LOW
PRESSURE SYSTEM AND ITS ASSOCIATED COLD FRONT WILL IMPACT THE REGION
AFTER 06Z TONIGHT THRU SUNDAY AFTERNOON. THIS STORM SYSTEM WILL
BRING A THREAT OF SHOWERS AND ISOLD TSTMS TO THE TAF SITES LATE
TONIGHT INTO SUNDAY MORNING. MVFR CIGS AND SOME BR ALSO POSSIBLE. THE
SFC COLD FRONT WILL MOVE ACROSS THE AREA SUNDAY...LEADING TO
IMPROVING CONDITIONS. WINDS WILL ALSO RAMP UP AROUND MID TO LATE
MORNING SUNDAY AND PERSIST THRU THE AFTERNOON HOURS. OVERALL...A
FAIRLY COMPLICATED FCST WITH AMENDMENTS PSBL THIS EVENING.

PREV DISCUSSION... /ISSUED 358 PM CST SAT DEC 13 2014/

SHORT TERM...
A HIGHLY AMPLIFIED UPPER AIR PATTERN CONTINUES ACROSS THE CONUS WITH
THE TEXAS AND OKLAHOMA PANHANDLES SITUATED AHEAD OF AN UPPER TROUGH
OVER THE FOUR CORNERS REGION. THIS UPPER TROUGH WILL PROVIDE A CHANCE
OF SHOWERS AND THUNDERSTORMS TO THE AREA LATER TONIGHT. MEANWHILE
SOUTHERLY SURFACE WINDS CONTINUE TO DRAW IN LOW-LEVEL MOISTURE INTO
THE AREA. WHILE THIS MOISTURE IS PRETTY SHALLOW...IT IS ABUNDANT AND
HAS RESULTED IN AREAS OF DENSE FOG AND LOW STRATUS THE PAST SEVERAL
NIGHTS AND SEE NO REASON FOR FOG AND LOW STRATUS NOT TO DEVELOP LATER
TONIGHT. THE ONE CAVEAT THOUGH IS SURFACE WINDS ARE STRONGER IN
MAGNITUDE WHICH MAY HELP TO KEEP VISIBILITIES ABOVE A QUARTER OF A
MILE. THUS HAVE OPTED TO NOT ISSUE A DENSE FOG ADVISORY FOR THIS AREA
TONIGHT.

THE UPPER TROUGH BECOMES NEGATIVELY TILTED BEFORE CLOSING OFF INTO AN
UPPER LOW LATE TONIGHT. THIS LOW WILL THEN TRACK EAST NORTHEAST ACROSS
THE NORTHERN TEXAS PANHANDLE AND THE OKLAHOMA PANHANDLE SUNDAY
MORNING. SHOWERS AND THUNDERSTORMS WILL DEVELOP LATE TONIGHT AHEAD OF
THIS SYSTEM AS LARGE SCALE ASCENT INCREASES WITH THE APPROACH OF THIS
SYSTEM. COOL MID LEVEL TEMPS ASSOCIATED WITH THIS SYSTEM WILL RESULT
IN STEEPENING LAPSE RATES WHICH WILL CONTRIBUTE TO MUCAPES OF 250-750
J/KG. BULK SHEAR VALUES AROUND 40 KTS WILL SUPPORT STORM ORGANIZATION
BUT THE OVERALL SEVERE THREAT WILL BE LIMITED GIVEN THE PROGRESSIVE
NATURE OF THIS SYSTEM. STILL THE STRONGER STORMS CAN BE CAPABLE OF
PRODUCING SMALL HAIL AND GUSTY WINDS. MOST LIKELY SCENARIO WILL BE A
SQUALL LINE MOVING EASTWARD ACROSS THE AREA BEFORE RACING OFF INTO
OKLAHOMA SUNDAY.

ANY LOW CLOUDS/FOG WILL BE SCOURED OUT EARLY SUNDAY ONCE THE FRONT
PUSHES THROUGH THE AREA AS DRIER AIR WORKS ITS WAY INTO THE AREA.
NORTHWEST WINDS WILL INCREASE BEHIND THIS DEPARTING SYSTEM LEADING TO
A BLUSTERY DAY. STILL HELD ONTO A MENTION OF RAIN DURING THE DAY OVER
MUCH OF THE AREA BUT BETTER CHANCES WILL LIE OVER THE OKLAHOMA
PANHANDLE AND NORTHEAST TEXAS PANHANDLE AS THE DEFORMATION ZONE NORTH
OF THE UPPER LOW MOVES OVER THIS AREA. THE RAIN WILL CHANGE OVER TO
SNOW SUNDAY EVENING AS TEMPS FALL BELOW FREEZING.

LONG TERM...
THE START OF THE NEW WORK WEEK WILL START WITH NEAR SEASONAL TEMPS
AND DRY CONDITIONS AS THE UPPER LOW PULLS OFF TO THE NORTHEAST AND
A LOW AMPLITUDE UPPER RIDGE BUILDS OVER THE FOUR CORNERS REGION.
HOWEVER THE UPPER PATTERN WILL QUICKLY BECOME ACTIVE BY WEDNESDAY AS
AN UPPER TROUGH EJECTS OFF THE CALIFORNIA COAST. THIS WILL BE
FOLLOWED BY A SECOND AND DEEPER UPPER TROUGH. THE SECOND TROUGH LOOKS
TO BE STRONGER IN MAGNITUDE AND THE PASSAGE OF A COLD FRONT CAN HELP
TO GENERATE PRECIPITATION. WHILE THE DETAILS OF THIS SYSTEM ARE NOT
TOO CLEAR AT THIS TIME SINCE ITS SEVERAL DAYS OUT IN TIME...BUT
A RAIN SNOW MIX LOOKS TO BE A POSSIBILITY WEDNESDAY EVENING THROUGH
FRIDAY.
