AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
409 PM CDT TUE APR 26 2011

.DISCUSSION...
ACTIVE WEATHER UNFOLDING ACROSS THE PANHANDLES THIS AFTERNOON...WITH
FIRE WEATHER IN THE SOUTHWEST TEXAS PANHANDLE AND SEVERE CONVECTION
ELSEWHERE.

AT DISCUSSION TIME...SURFACE TROUGH HAS NUDGED INTO THE WESTERN PART
OF THE TEXAS PANHANDLE. DRY SOUTHWESTERLY WINDS HAVE OVERTAKEN THESE
AREAS WITH DEWPOINTS FALLING INTO THE LOWER AND MIDDLE 20S. THESE
WESTERLY WINDS WILL BEGIN TO INCREASE AND MAY FLIRT WITH WIND
ADVISORY CRITERIA...BUT WILL FOREGO A WIND ADVISORY ATTM. TO THE
EAST...SOUTHEASTERLY UPSLOPE WINDS HAVE CREATED AN AREA OF INCREASED
LOW LEVEL CONVERGENCE ALONG SURFACE TROUGH. CONVECTION HAS ALL READY
FIRED THIS AFTERNOON ALONG AND EAST OF A LINE FROM TEXLINE TO
AMARILLO AS DEWPOINTS REMAIN IN THE LOWER TO MIDDLE 40S ACROSS THESE
AREAS. SPC MESOANALYSIS PAINTS AROUND 500 J/KG OF MLCAPE ACROSS THE
CENTRAL ZONES SO ANY STORM THAT DEVELOPS COULD AT TIMES APPROACH
SEVERE LIMITS WITH MAINLY A LARGE HAIL THREAT.

COLD FRONT WILL CONTINUE TO APPROACH THE PANHANDLES TONIGHT...WITH
WINDS FLIPPING OVER TO THE NORTHWEST AND NORTH. CHANCES FOR SHOWERS
AND STORMS WILL PERSIST INTO THE EVENING/OVERNIGHT AS UPPER LEVEL
DISTURBANCE TRAVERSES THE REGION. POP STRUCTURE WAS LARGELY RETAINED
BUT INCREASED PRECIP CHANCES TO CATEGORICAL ACROSS THE EASTERN
OKLAHOMA PANHANDLE AND NORTHEAST TEXAS PANHANDLE WITH A SHARP
GRADIENT EXTENDING BACK TO THE SOUTHWEST WITH NON MENTIONABLE POPS
ACROSS THE SOUTHWEST TEXAS PANHANDLE. OVERNIGHT LOW TEMPS WILL RANGE
FROM THE UPPER 30S IN THE WEST TO UPPER 40S TO NEAR 50 IN THE EAST.
MAV/MET TEMPS GENERALLY ACCEPTED FOR TONIGHT. UPPER LEVEL TROUGH
SHOULD BE SHIFTING EAST OF THE REGION TOMORROW MORNING AND HELD ON TO
SOME LOW END RAIN CHANCES ACROSS THE NORTHEAST ZONES AS SHORTWAVE
TROUGH EXITS.

COOLER TEMPS IN STORE FOR WEDNESDAY IN WAKE OF THE COLD FRONT WHICH
MOVES THROUGH THE AREA TONIGHT. ANTICIPATING LOWER TO MIDDLE 60S
ACROSS MUCH OF THE REGION WITH BREEZY NORTHERLY WINDS THROUGH ABOUT
MIDDAY. GRADIENT BEGINS TO RELAX AS SURFACE HIGH PRESSURE SETTLES
INTO THE REGION LATE TOMORROW AFTERNOON. WINDS SHOULD GO FAIRLY LIGHT
ALONG WITH CLEARING SKIES WEDNESDAY NIGHT WHICH WILL ALLOW FOR A GOOD
RADIATIONAL COOLING NIGHT. TEMPS WILL FALL INTO THE 30S IN MOST SPOTS
EXPECT FOR POSSIBLY OFF THE CAPROCK IN THE SOUTHEAST TEXAS PANHANDLE.
LOCATIONS IN THE NORTHWEST TEXAS PANHANDLE AND WESTERN OKLAHOMA
PANHANDLE MAY DEEP TO NEAR FREEZING. WILL NOT ISSUE A FREEZE WATCH AT
THIS TIME AND PASS CONCERNS ON TO THE NEXT SHIFT.

QUIET WEATHER EXPECTED ON THURSDAY AS DRY WNW FLOW WILL PREVAIL
ACROSS THE PANHANDLES. SHORTWAVE RIDGING WILL QUICKLY MOVE EAST OF
THE REGION AS UPPER LEVEL FLOW BECOMES MORE SOUTHWESTERLY IN ADVANCE
OF NEXT UPPER LEVEL STORM SYSTEM. MODELS CONCUR ON DEVELOPING A
SURFACE LOW ACROSS SOUTHEASTERN COLORADO WITH TROUGH EXTENDING
SOUTHWARD INTO THE PANHANDLES. SOUTHWEST WINDS WILL INCREASE WITH
WARMING TEMPS...WITH HIGHS CLIMBING INTO THE UPPER 80S AND LOWER 90S.
12Z MEX NUMBERS WERE INCREASED AS DOWNSLOPE COMPONENT SHOULD ALLOW
FOR A NICE WARMUP.

COLD FRONT MOVES THROUGH THE AREA SATURDAY WHICH MAY CAUSE A TEMP
GRADIENT FROM NORTH TO SOUTH...CURRENTLY TARGETING LOWER 60S IN THE
NORTHWEST TO NEAR 80 IN THE SOUTHEAST. COOLER TEMPS ON SUNDAY BEHIND
THE FRONT. PRECIP CHANCES DO NOT LOOK TOO GOOD IN THE EXTENDED SO
FORECAST WILL REMAIN DRY.

&&

.FIRE WEATHER...
CRITICAL FIRE WEATHER CONDITIONS WILL CONTINUE INTO EARLY THIS EVENING
ACROSS THE SOUTHWEST TEXAS PANHANDLES AS WESTERLY WINDS INCREASE TO AROUND
25 MPH WITH HIGHER GUSTS AND MINIMUM RELATIVE HUMIDITY VALUES FALL BELOW
15 PERCENT. ELEVATED TO CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED ON
FRIDAY AS DRY SOUTHWESTERLY WINDS INCREASE ACROSS THE PANHANDLES.
