AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
415 PM CDT WED APR 29 2009

.DISCUSSION...
CLOUDS HAVE BROKEN ACROSS THE PANHANDLES ALLOWING FOR MOST OF THE
AREA TO WARM NICELY. A DRYLINE EXTENDS ROUGHLY FROM NEAR GUYMON TO
DUMAS TO FRIONA AND CAN BE READILY DISTINGUISHED BY A LINE OF CU ON
VISIBLE SAT IMAGERY. CONVECTION IS ALREADY BEGINNING TO DEVELOP
ALONG THIS LINE. LATEST LAPS ANALYSIS SHOWS SBCAPE VALUES IN THE
2500-3500 J/KG RANGE EAST OF THE DRYLINE. IN ADDITION...0-6 KM BULK
SHEAR VALUES ARE SUPPORTIVE OF SUPERCELLS. THUS...ANY STORMS THAT
DEVELOP ARE LIKELY TO BE SEVERE THIS AFTERNOON AND EVENING WITH LARGE
HAIL AND DAMAGING WINDS. LOW LEVEL SHEAR IS ALSO SUFFICIENT ENOUGH
THAT AN ISOLATED TORNADO CANNOT BE RULED OUT.

THE UPPER LEVEL DISTURBANCE RESPONSIBLE FOR TRIGGERING THE STORMS
WILL EXIT THE AREA EARLY TONIGHT. IN ITS WAKE...A COLD FRONT WILL
BEGIN TO APPROACH THE AREA THURSDAY. THE COLD FRONT WILL STALL ACROSS
THE AREA AND FINALLY MOVE THROUGH THE CWA FRIDAY. BOTH THE NAM AND
GFS DEPICTED SOME PRECIP ACROSS THE NORTHERN TX PANHANDLE AND THE OK
PANHANDLE FRIDAY BEHIND THE FRONT FRIDAY MORNING. THUS...INSERTED
SLIGHT CHANCE POPS TO ACCOUNT FOR THIS. BELOW NORMAL TEMPERATURES CAN
BE EXPECTED FOR THE WEEKEND.

THE 12Z GFS AND ECMWF ARE IN VAST DISAGREEMENT WITH TIMING OF
FEATURES IN THE EXTENDED. MADE VERY FEW CHANGES IN THE EXTENDED UNTIL
THE MEDIUM RANGE MODELS COME INTO BETTER AGREEMENT. HOWEVER...BOTH
SOLUTIONS DO SHOW THAT THE ACTIVE WX PATTERN SHOULD CONTINUE.

.FIRE WEATHER...
SEVERAL ROUNDS OF PRECIPITATION CHANCES AND HIGHER RELATIVE

UPCOMING WEEK.

PREV DISCUSSION... /ISSUED 1210 PM CDT WED APR 29 2009/

UPDATE...
UPDATED THE FORECAST TO EXTEND PRECIP CHANCES TO COVER THE WESTERN
ZONES FOR THIS AFTERNOON AND TONIGHT. OUTFLOW BOUNDARIES LEFT IN THE
WAKE OF EARLY MORNING TSTRMS THIS MORNING CAN BE SEEN ON RADAR AND
VIS SAT IMAGES. CURRENT OBS ALSO SHOW DEWPOINTS WELL INTO THE 50S
WEST ACROSS THE TX/NM STATE LINE. IT APPEARS THAT THE DRYLINE MAY NOT
MIX AS FAR EAST AS PREVIOUSLY THOUGHT...WHICH IS ALSO DEPICTED IN
LATEST 12Z NAM AND RUC. THUS...GRIDS HAVE BEEN UPDATED TO REFLECT THE
NEW TRENDS. UPDATED ZFP HAS BEEN SENT.

NUTTALL

PREV DISCUSSION... /ISSUED 648 AM CDT WED APR 29 2009/

UPDATE...
NOCTURNAL THUNDERSTORM ACTIVITY HAS MOVED EAST OF THE AREA THIS
MORNING...SO SEVERE THUNDERSTORM WATCH 208 WAS CANCELLED.
REDEVELOPMENT IS EXPECTED LATER TODAY AHEAD OF A DEVELOPING DRYLINE.
THE REST OF THE FORECAST IS ON TRACK.

NUNEZ

PREV DISCUSSION... /ISSUED 642 AM CDT WED APR 29 2009/

AVIATION...
WIDESPREAD NOCTURNAL CONVECTION ASSOCIATED WITH THE INITIAL SHORTWAVE
TROF HAS ALMOST EXITED THE PANHANDLES TO THE EAST. THIS SHOULD LEAVE
THE AREA IN AN AREA OF LARGE SCALE SUPPRESSION FOR THE FIRST PART OF
THE DAY SO NO ADDITIONAL CONVECTION IS EXPECTED THROUGH MID
AFTERNOON. HOWEVER...BY LATE AFTERNOON...DIURNAL HEATING WILL
INTERACT WITH A MOIST...CONDITIONALLY UNSTABLE ENVIRONMENT TO PRODUCE
ADDITIONAL SHOWERS AND THUNDERSTORMS. THE BEST CHANCES WILL BE IN THE
CENTRAL/EASTERN COUNTIES SO CB REMARKS WERE ADDED TO KAMA/KGUY FROM
22Z TO 03Z WITH NO MENTION AT KDHT.

IN THE INTERIM...WE WILL HAVE SOME LOW CLOUDS/VSBYS TO DEAL WITH.
RECENT SATELLITE IMAGERY SHOWS A GAPING HOLE IN THE LOW CIGS RIGHT
OVER KAMA BUT THIS SHOULD FILL BACK IN THIS MORNING DESPITE LOW LEVEL
SOUTH SOUTHWEST WINDS. HOWEVER...TEMPORAL CONFIDENCE IS NOT THAT
HIGH SO I HAVE OPTED TO USE A TEMPO GROUP TO COVER LOW CIGS FROM 13Z
TO 17Z. ELSEWHERE...I CARRIED PREVAILING IFR /OR LOWER/ CIGS THROUGH
MID MORNING BEFORE LIFTING TO LOW END MVFR. VFR CIGS ARE FORECAST AT
ALL TAF SITES BY 17Z. THERE IS A CHANCE THAT LOW CIGS COULD RETURN
TONIGHT AT KAMA/KGUY BUT THIS HAS BEEN OMITTED FOR NOW GIVEN THE LOW
CONFIDENCE.

PREV DISCUSSION... /ISSUED 507 AM CDT WED APR 29 2009/

DISCUSSION...
NOCTURNAL THUNDERSTORM ACTIVITY HAS BECOME FOCUSED OVER THE EASTERN
PARTS OF THE PANHANDLES. ELEVATED DEVELOPMENT MAY RESULT IN
MARGINALLY SEVERE WEATHER AS AN UPPER LEVEL DISTURBANCE DRIVES THIS
ACTIVITY EAST.

IN THE MEANTIME...THE NEXT DISTURBANCE JUST CLEARED THE FOUR CORNERS...
MOVING EAST TOWARDS THE PLAINS STATES. AT THE SURFACE...THE ANTICIPATED
FORMATION OF A DRYLINE MAY BE SLOWER TO DEVELOP SINCE 50+ DEGREE
DEWPOINTS STILL EXISTED OVER THE EASTERN PLAINS OF NEW MEXICO EARLY
THIS MORNING. ANY DELAY TO THE EROSION OF THE LOW CLOUD COVER WILL
HINDER THUNDERSTORM REDEVELOPMENT THIS AFTERNOON IN ADDITION TO
MINIMIZING THE SEVERE THREAT. FOR NOW...WE WILL MAINTAIN POPS OVER
THE CENTRAL AND EASTERN PARTS OF PANHANDLES TODAY AND EAST OF THE
CAPROCK TONIGHT.

ONCE THE DISTURBANCE EXITS EAST...A COLD FRONT WILL EDGE INTO THE
OKLAHOMA AND NORTHERN TEXAS PANHANDLE BEFORE STALLING AS THE UPPER
LOW PRESSURE SYSTEM ADVANCES INTO THE SOUTHERN HIGH PLAINS. THE BEST
CHANCE OF RAIN SHOULD REMAIN NORTH AND EAST OF THE AREAS THURSDAY
WHERE ESSENTIAL MOISTURE WILL BE PRESENT.

CONFLUENCE FLOW EMERGES BRIEFLY THURSDAY NIGHT AND FRIDAY...BRINGING
A BREAK IN THE RAIN. CONSIDERABLE CLOUD COVER SHOULD KEEP CONDITIONS
COOL HOWEVER.

RAIN CHANCES RETURN THIS WEEKEND AS THE WEATHER PATTERN REMAINS
ACTIVE. TIMING ISSUES STILL EXIST IN THE EXTENDED FORECAST THOUGH THE
ECMWF CONTINUES TO DEPICT A LOW PRESSURE SYSTEM AFFECTING THE
SOUTHERN HIGH PLAINS AROUND TUESDAY.

NUNEZ

FIRE WEATHER...
LOW TO MODERATE FIRE WEATHER CONDITIONS SHOULD PREVAIL ACROSS THE
TEXAS AND OKLAHOMA PANHANDLES TODAY THROUGH EARLY NEXT WEEK GIVEN THE
FREQUENT CLOUD COVER AND OCCASIONAL PERIODS OF PRECIPITATION.
