AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
838 PM CDT WED JUN 1 2011

.UPDATE...
ADJUSTED POPS FOR THIS EVENING AND UPDATED HOURLY TEMPERATURES AND
DEWPOINTS BASED ON CURRENT TRENDS. ALSO ADDED THE FAR NORTHERN TEXAS
PANHANDLE COUNTIES IN THE CURRENT SEVERE THUNDERSTORM WATCH.

&&

.DISCUSSION...
TWO DISTINCT AREAS OF SHOWERS AND THUNDERSTORMS CONTINUE TO MOVE
ACROSS THE NORTHWEST TEXAS AND OKLAHOMA PANHANDLES AS WELL AS
SOUTHWEST KANSAS THIS EVENING. CURRENTLY...THE AREA OF CONCERN IS A
CLUSTER OF THUNDERSTORMS MOVING ACROSS WESTERN DALLAM AND CIMARRON
COUNTIES. THESE THUNDERSTORMS WILL CONTINUE TO PUSH EAST OVER THE
NEXT SEVERAL HOURS POSSIBLY BRINGING DAMAGING WIND GUSTS UP TO 70
MPH...LARGE HAIL UP TO THE SIZE OF QUARTERS...AND FREQUENT CLOUD TO
GROUND LIGHTNING MAINLY ACROSS THE OKLAHOMA AND FAR NORTHERN TEXAS
PANHANDLES. WITH A STRENGTHENING LOW LEVEL JET AS WELL AS AN
ENVIRONMENT THAT WILL SUPPORT ONGOING THUNDERSTORMS...DECIDED TO GO
AHEAD AND INCLUDE THE FAR NORTHWESTERN AND NORTHERN TEXAS PANHANDLE
COUNTIES IN THE CURRENT SEVERE THUNDERSTORM WATCH THAT REMAINS IN
EFFECT UNTIL 1AM CDT.

ANOTHER AREA OF SHOWERS AND THUNDERSTORMS CONTINUES TO PUSH ACROSS
EASTERN NEW MEXICO JUST SOUTH OF INTERSTATE 40. THE ENVIRONMENT IS
NOT QUITE AS FAVORABLE FOR SEVERE THUNDERSTORM DEVELOPMENT AND
BELIEVE THESE STORMS WILL LOSE A LOT OF STEAM AS THEY MOVE INTO THE
SOUTHEAST TEXAS PANHANDLE...AN AREA THAT IS FAIRLY WELL CAPPED AS
EVIDENT ON THE 00Z AMA SOUNDING. AS A RESULT...LOWERED AND/OR REMOVED
POPS SOUTHEAST OF A LINE FROM HEREFORD...TO AMARILLO...TO CANADIAN.

OTHERWISE...THE CURRENT FORECAST IS IN GOOD SHAPE AND ADJUSTED HOURLY
TEMPERATURES AND DEWPOINTS BASED ON CURRENT TRENDS AND EXPECTED
CONDITIONS OVER THE NEXT 12 HOURS.

KNS

&&

.AVIATION... FOR THE 00Z TAFS...GENERALLY VFR AND BREEZY TO WINDY
CONDITIONS ARE EXPECTED.

CURRENT TSRA COMPLEX NORTHWEST OF KDHT AND KGUY WILL CONTINUE TO
MOVE EAST AND SHOULD WEAKEN OVER THE NEXT FEW HOURS. ADDED TEMPO
GROUP FOR GUSTY WINDS AT KDHT AND KGUY AS GUSTS MAY EXCEED 35 KTS.
KEPT CONDITIONS VFR AT THESE SITES FOR NOW AS NOT SURE EITHER SITE
WILL BE DIRECTLY AFFECTED. IF TSRA WERE TO DIRECTLY MOVE OVER THESE
SITES...BRIEF MVFR/IFR CONDITIONS WOULD BE POSSIBLE. BELIEVE TSRA
WILL END BY 04Z.

REMOVED CB MENTION AT KAMA WITH VERY LOW CONFIDENCE THAT TSRA WILL
AFFECT THIS SITE.

NONCONVECTIVE LOW LEVEL WIND SHEAR IS POSSIBLE AT ALL SITES
03-12Z WITH WINDS 500-2000 FT AGL 35-50 KTS...BUT DID NOT MENTION WITH
LOW CONFIDENCE OF OCCURRENCE AS SURFACE WINDS MAY BE GUSTY.

THERE IS A SMALL CHANCE THAT A FEW GUSTS MAY APPROACH 40 KTS AT KAMA
AFTER 03Z. DID NOT ISSUE AN AIRPORT WEATHER WARNING AT THIS TIME DUE
TO VERY LOW CONFIDENCE.

MBS

.PREV DISCUSSION... /ISSUED 344 PM CDT WED JUN 1 2011/

FORECAST CONCERNS WILL REVOLVE AROUND THUNDERSTORM CHANCES LATE THIS
AFTERNOON INTO TONIGHT.

CURRENTLY...SURFACE TROUGH IS SITUATED ACROSS EASTERN NEW MEXICO AND
EASTERN COLORADO THIS AFTERNOON. MOISTURE REMAINS IN PLACE ACROSS THE
PANHANDLES WITH MID/UPPER 50 DEWPOINTS IN THE NORTHWEST TO LOWER 60
DEWPOINTS IN THE SOUTHEAST. TEMPERATURES GENERALLY ARE IN THE LOWER
90S IN MOST LOCATIONS AS OF DISCUSSION TIME.

LATEST SPC MESOANALYSIS  PAINTS MLCAPE VALUES OF ABOUT 2000 TO 3000
J/KG...WITH MLCINH LESS THAN 50 J/KG. EXPECT THIS INHIBITION TO ERODE
COMPLETELY WITHIN THE NEXT HOUR OR SO. CONVECTION HAS ALL READY
DEVELOPED ON THE HIGHER TERRAIN OF NEW MEXICO THIS AFTERNOON...AND
SHOULD CONTINUE TO MOVE EASTWARD INTO THE PANHANDLES AS THE AFTERNOON
PROGRESSES. SHEAR WILL BE SUFFICIENT ENOUGH THIS AFTERNOON/EVENING TO
SUPPORT ORGANIZED STORMS. THESE STORMS LIKELY WILL BECOME SEVERE
WITH LARGE HAIL UP TO GOLF BALLS AND DAMAGING WINDS BEING THE PRIMARY
HAZARDS...WITH FAVORED LOCATIONS NORTHWEST AND NORTH OF THE HIGHWAY
60 CORRIDOR. TORNADO THREAT APPEARS TO BE FAIRLY LOW GIVEN LARGE TEMP
AND DEWPOINT SPREADS. 4KM WRF AND HRRR HAS BEEN PRETTY INSISTENT ON
THUNDERSTORMS MOVING INTO THE OKLAHOMA PANHANDLE AND NORTHERN PARTS
OF THE TEXAS PANHANDLE THIS AFTERNOON. WILL CARRY CHANCE POPS UP IN
THE NORTH TO NON MENTIONABLE POPS IN THE SOUTHEAST TEXAS PANHANDLE
WHERE LIFT WILL BE WEAKEST.

TEMPERATURES WILL BE ON THE MILD SIDE TONIGHT AS SOUTHERLY WINDS
REMAIN ABOUT 20 MPH. OVERNIGHT LOWS SHOULD RANGE FROM THE LOWER 60S
IN THE NORTHWEST TO UPPER 60S IN THE SOUTHEAST. SIDE CLOSER TO THE
WARMER MET NUMBERS.

LEE SIDE TROUGHING CONTINUES INTO THURSDAY...WITH SOUTH SOUTHWESTERLY
WINDS INCREASING BETWEEN 20 AND 30 MPH IN THE AFTERNOON. MAV WINDS
HAVE BEEN RUNNING WAY TOO HIGH HERE RECENTLY AND ARE SUGGESTING WIND
ADVISORY LEVEL WINDS FOR TOMORROW. HOWEVER...LACK OF STRONG 700MB AND
500MB WINDS TO MIX INTO SHOULD PREVENT WINDS FROM GETTING TOO OUT OF
CONTROL. ANOTHER WARM DAY IS IN STORE ON THURSDAY AS HIGH TEMPS ONCE
AGAIN WILL BE IN THE LOWER TO MIDDLE 90S. WARMER MET NUMBERS WERE
FAVORED HERE AS WELL.

UPPER LEVEL PATTERN THROUGH THE WEEKEND WILL BE CHARACTERIZED BY
UPPER TROUGH OUT WEST WITH UPPER RIDGING DOWNSTREAM. HELD ON TO THE
LOW END THUNDERSTORM CHANCES FOR THURSDAY NIGHT AND FRIDAY NIGHT IN
THE WESTERN ZONES AS THESE AREAS WILL BE ON WESTERN PERIPHERY OF
UPPER RIDGE. BY SATURDAY...UPPER LEVEL RIDGING SHOULD BE FAR ENOUGH
WEST TO KEEP CHANCES FOR SHOWERS AND STORMS OVER NEW MEXICO. ABOVE
NORMAL TEMPERATURES WILL CONTINUE THROUGH THE WEEKEND INTO EARLY NEXT
WEEK.

&&

.FIRE WEATHER...
ALTHOUGH SOUTHERLY WINDS WILL INCREASE BETWEEN 20 AND 30 MPH ON
THURSDAY...MINIMUM RELATIVE HUMIDITY VALUES WILL BE BETWEEN 20 AND
30 PERCENT ACROSS THE PANHANDLES. ON FRIDAY...SIMILAR WIND SPEEDS
CAN BE EXPECTED WITH MINIMUM RELATIVE HUMIDITY VALUES DIPPING
SLIGHTLY BELOW 20 PERCENT ACROSS THE FAR WESTERN SECTIONS OF THE
OKLAHOMA AND TEXAS PANHANDLES. HOWEVER...CHANCES FOR PRECIPITATION
TONIGHT AND THURSDAY NIGHT ACROSS THESE AREAS AND ITS EFFECTS ON
FUELS WILL PRECLUDE MENTIONING ELEVATED FIRE WEATHER CONDITIONS AT
THIS TIME.

&&

.AMA WATCHES/WARNINGS/ADVISORIES...
TX...NONE.
OK...NONE.
