AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
622 PM CDT SAT MAY 26 2012

.AVIATION...
A DRYLINE OVER EASTERN NEW MEXICO ALONG WITH DAYTIME HEATING AND
SOUTHWESTERLY FLOW ALOFT WILL COMBINE TO CAUSE ISOLATED TO SCATTERED
CONVECTION ACROSS THE TEXAS AND OKLAHOMA PANHANDLES THROUGH THE LATE
EVENING HOURS. INCLUDED A TEMPO GROUP FOR CONVECTION ALONG WITH A
VCTS REMARK AT ALL THREE TAF SITES UNTIL AROUND 04Z SUNDAY. VFR
CONDITIONS WILL PREVAIL. SOUTH TO SOUTHEAST WINDS 20 TO 30 KNOTS WITH
HIGHER GUSTS WILL DIMINISH AFTER 03Z TO AROUND 15 TO 25 KNOTS WITH
HIGHER GUSTS. WINDS WILL BECOME SOUTH TO SOUTHWEST WINDS AFTER 14Z
SUNDAY.

.PREV DISCUSSION... /ISSUED 442 PM CDT SAT MAY 26 2012/

DISCUSSION...
CURRENT VIS SATELLITE IMAGERY SHOWS GROWING CU FIELD IN A
HOT...MOIST...AND WELL MIXED AIR MASS. THE DRYLINE HAS PUSHED EAST
INTO THE NORTHWEST PANHANDLES BUT SHOULD RETREAT BACK INTO NM AS THE
SURFACE FLOW BACKS A LITTLE TO THE SOUTHEAST AS A SURFACE LOW LIFTS
NORTH INTO CO. MEANWHILE A BROAD UPPER LOW CONTINUES TO DIG OVER THE
GREAT BASIN WHILE AN UPPER RIDGE SITS OVER THE LOWER MISSISSIPPI
VALLEY. THE SOUTHWEST UPPER FLOW WAS DRAWING IN MOISTURE FROM
TROPICAL DEPRESSION BUD /LOCATED NEAR THE SOUTHWEST COAST OF MEXICO/ WHERE
DEW POINTS WERE RUNNING FROM THE MID 40S TO THE UPPER 50S. EXPECT CI
TO FORM NEAR THE DRYLINE AND PROPAGATE TO THE EAST THIS EVENING GIVEN
THE 40 KTS MID-LEVEL FLOW. WHILE CONVECTION WILL NOT BE ALL THAT
ORGANIZED...STEEP MID-LEVEL LAPSE RATES AND MIXED LAYER CAPES AROUND
1000-1500 J/KG CAN RESULT IN SOME STORMS TO BECOME SEVERE. STORMS
WILL BE HIGH BASED GIVEN LARGE TEMP/DEWPOINT DEPRESSIONS SO THE
TORNADO THREAT WILL BE MARGINAL. STORMS SHOULD DIMINISH FOR THE MOST
PART AFTER SUNSET BUT HAVE SLIGHT CHANCE POPS IN LATE TONIGHT TO
ACCOUNT FOR ANY LINGERING CONVECTION OUT WEST PROPAGATING INTO THE
AREA.

THE UPPER TROUGH WILL LIFT INTO THE NORTHERN ROCKIES ON SUNDAY...CAUSING
THE UPPER FLOW TO VEER MORE TO THE SOUTHWEST. AT THE SURFACE...A LEE-SIDE
TROUGH WILL DEEPEN ACROSS EASTERN NM CAUSING THE DRYLINE TO SURGE INTO
THE WESTERN TX/OK PANHANDLES. ISOLATED STORMS CAN DEVELOP EAST OF THE
DRYLINE AS THE CAP WEAKENS AND THERE IS A CHANCE THAT A FEW STORMS
CAN BECOME SEVERE. AGAIN STRONG WINDS AND LARGE HAIL WILL BE THE
PRIMARY THREATS. SLIGHT HEIGHT FALLS AHEAD OF THE UPPER TROUGH WILL
RESULT IN COOLER CONDITIONS...ALTHOUGH STILL EXPECT TEMPS TO REMAIN
ABOVE NORMAL WITH HIGHS IN THE MID 80S TO LOWER 90S.

THE UPPER FLOW WILL TRANSITION TO ZONAL EARLY IN THE WEEK AS THE
UPPER LOW MOVES INTO THE NORTHERN PLAINS. A COLD FRONT WILL SLIDE
THROUGH THE PANHANDLES WHERE IT WILL STALL SOUTH OF THE AREA. SURFACE
HIGH PRESSURE BUILDING ACROSS THE PLAINS WILL LEAD TO A COOLER AND
DRIER AIR MASS TO SPREAD ACROSS THE AREA ALTHOUGH THIS HIGH WILL
QUICKLY SLIDE EAST DURING THE DAY. AS IT DOES SO...SURFACE WINDS WILL
VEER BACK AROUND TO THE SOUTHEAST BY THE EVENING. MOISTURE WILL
INCREASE ACROSS THE PANHANDLES MONDAY EVENING. MODELS CONTINUE TO
PAINT SOME QPF IN THE VICINITY OF THE FRONTAL BOUNDARY AS MOISTURE
WILL POOL NEAR THIS FRONT. HAVE OPTED TO KEEP THE FORECAST DRY MONDAY
EVENING ALTHOUGH MAY HAVE TO LOOK INTO INSERTING POPS IN THE
SOUTHEAST TX PANHANDLE IF THE NEXT COUPLE OF MODEL RUNS CONTINUE TO
SUGGEST THIS. AS PREVIOUSLY MENTIONED...EXPECT A COOLER DAY WITH
HIGHS IN THE 80S.

MEDIUM RANGE MODELS HAVE COME IN WETTER MID TO LATE NEXT WEEK WITH
UPPER RIDGING OVER THE WESTERN CONUS AND NORTHWEST UPPER FLOW SETTING
UP ACROSS THE PANHANDLES. THE DRYLINE CAN MIX OUT INTO THE EASTERN
PANHANDLES TUESDAY WHERE ISOLATED STORMS CAN DEVELOP ACROSS THE
EASTERN ZONES. HAVE INTRODUCED POPS WED AND WED NIGHT WITH A
SHORTWAVE TROUGH DROPPING SOUTHEAST ALONG THE EASTERN PERIPHERY OF
THE RIDGE. BOTH THE ECMWF AND GFS PAINT QPF OVER MUCH OF THE AREA AT
THE END OF THE WEEK LIKELY KEYING ON MINOR DISTURBANCES MOVING THROUGH
THE UPPER FLOW TRIGGERING CONVECTION ON THE HIGHER TERRAIN. STORM
DEVELOPMENT DEPENDS GREATLY ON THE AMOUNT OF MOISTURE AVAILABLE AND
THUS HAVE OPTED TO KEEP THESE PERIODS DRY FOR NOW GIVEN THIS UNCERTAINTY.

CLK

FIRE WEATHER...
THE DRYLINE WILL PUSH INTO THE EASTERN PANHANDLES SUNDAY AS A SURFACE
LEE-SIDE TROUGH STRENGTHENS ACROSS EASTERN NM. SOUTHWEST WINDS
BEHIND THE DRYLINE WILL DRAW IN A HOT AND DRY AIR MASS. GIVEN THESE
CONDITIONS...EXPECT MINIMUM RELATIVE HUMIDITIES TO FALL TO AROUND 5
TO 15 PERCENT. A TIGHTENING PRESSURE GRADIENT NEAR THE SURFACE TROUGH
WILL LEAD TO WINDS TO INCREASE TO AROUND 15 TO 25 MPH. THE
COMBINATION OF THE BREEZY SOUTHWEST WINDS AND LOW RELATIVE HUMIDITIES
CAN RESULT IN ELEVATED FIRE WEATHER CONDITIONS. HOWEVER THIS IS
CONDITIONAL DEPENDENT ON THE AMOUNT OF RAINFALL THIS AREA WILL
RECEIVE TONIGHT. ALTHOUGH RELATIVE HUMIDITIES CAN FALL AT OR BELOW 15
PERCENT ACROSS THE WESTERN PANHANDLES EARLY IN THE WEEK...WINDS ARE
EXPECTED TO BE UNDER 20 MPH WHICH CAN PRECLUDE ELEVATED FIRE WEATHER
CONDITIONS.
