Severe Thunderstorm Warning 164, NWS Lubbock, TX

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
232 PM CDT SUN JUN 3 2007

.SHORT TERM...
SIMILAR SITUATION TODAY AS YESTERDAY WITH NORTHWEST FLOW ALOFT
COMPLIMENTS OF AN UPPER LOW OVER SOUTHWESTERN WISCONSIN AND A
RIDGE JUST WEST OF THE CONTINENTAL DIVIDE. A FAIRLY STRONG
SHORTWAVE SEEN ON SATELLITE...MOVING EAST-SOUTHEAST FROM SOUTHWEST
NEW MEXICO COMBINED WITH VERY UNSTABLE ATMOSPHERE AND A COUPLE OF
SURFACE BOUNDARIES AROUND THE REGION TO AID IN THUNDERSTORMS
DEVELOPING DURING THE AFTERNOON AND MOVING EASTWARD DURING THE
NIGHT AS AN MCS. THERE ARE ALSO A COUPLE OF WEAKER DISTURBANCE
EMBEDDED IN THE NORTHWEST FLOW ALOFT MOVING THROUGH CENTRAL WYOMING
AND COLORADO...THUNDERSTORMS ALREADY DEVELOPING OVER THE SAN JUAN
MOUNTAINS...THUS ANOTHER MCS MAY DEVELOP LATER TONIGHT OVER
SOUTHEAST COLORADO/NORTHEAST NEW MEXICO AND MOVE SOUTHEAST ACROSS
THE REGION. SOME OF THE STORMS THAT MOVE THROUGH THE REGION TONIGHT
MAY BECOME SEVERE. EXPECT MONDAY TO BE SIMILAR TO TODAY WITH
PRECIPITATION MOVING EAST OF THE FORECAST AREA BY EARLY MORNING...
THEN CONVECTION AGAIN DEVELOPING OVER THE HIGHER TERRAIN OF NEW
MEXICO LATER IN THE AFTERNOON.

.LONG TERM...
PATTERN CHANGE WILL BE ONGOING AT THE BEGINNING OF THE EXTENDED
PERIOD MONDAY NIGHT AS UPPER LEVEL RIDGE ACROSS THE SOUTHWESTERN
CONUS AND GREAT BASIN TRANSLATES EASTWARD...WITH RIDGE AXIS
APPROACHING THE CONTINENTAL DIVIDE EARLY TUESDAY. STILL SHOULD BE
ENOUGH MOISTURE AND INSTABILITY TO ALLOW FOR THE DEVELOPMENT OF
SCATTERED THUNDERSTORMS EVOLVING UPSCALE INTO A MESOSCALE COMPLEX
DURING THE LATE EVENING HOURS MONDAY. MODELS HAVE BEEN VERY
CONSISTENT FOR THE PAST FEW DAYS WITH BRINGING AN MCS SOUTHWARD
ACROSS THE WESTERN SOUTH PLAINS LATE MONDAY INTO EARLY TUESDAY
MORNING. THIS SCENARIO SEEMS REASONABLE GIVEN UPPER FLOW AND
INITIATION ONCE AGAIN ON THE HIGHER TERRAIN OF EASTERN NEW MEXICO.
THUS WILL UP POPS TO LIKELY ACROSS THE WESTERN AND CENTRAL ZONES
MONDAY NIGHT.

CANNOT RULE OUT AT LEAST ISOLATED THUNDERSTORMS ON TUESDAY BUT AS
UPPER RIDGE EDGES FARTHER EASTWARD...MID LEVEL WARMING AND
DECREASING UPPER SUPPORT MAY MAKE CONVECTIVE INITIATION MORE
DIFFICULT. UPPER LOW MOVING ACROSS THE NORTHERN ROCKIES WILL BEGIN
TO SQUASH RIDGE WEDNESDAY THUS ONGOING FORECAST OF VERY WARM
TEMPERATURES AND VERY LOW POPS LOOKS GOOD. TEMPS LIKELY TO PUSH WELL
INTO THE 90S MOST AREAS WEDNESDAY WITH STRONG DOWNSLOPE WARMING.
WITH TIGHTENING LOW TO MID LEVEL PRESSURE GRADIENT AND LEE SIDE
SURFACE LOW EXTENDING SOUTH FROM THE CENTRAL PLAINS...WILL LIKELY
BECOME BREEZY WITH SW WINDS DURING THE AFTERNOON ON WEDNESDAY AND
THURSDAY. SOUTHERN STREAM UPPER TROUGH MAY APPROACH THE AREA BY
FRIDAY AND SATURDAY...ALONG WITH POSSIBLE FRONT MOVING SOUTHWARD OUT
OF THE CENTRAL PLAINS. THUS SLIGHT CHANCE POPS WILL CONTINUE INTO
NEXT WEEKEND.

&&

.AVIATION...
FOR KLBB AND KCDS...THUNDERSTORMS ARE AGAIN DEVELOPING OVER THE
HIGHER TERRAIN OF NEW MEXICO AND COLORADO THIS AFTERNOON. THESE
STORMS ARE EXPECTED MOVE EAST AND SOUTHEAST ACROSS THE REGION
DURING THE NIGHT WITH THE BEST CHANCE FOR THUNDERSTORMS EXPECTED
TO BE BETWEEN 02Z AND 06Z OVER KLBB AND BETWEEN 04 AND 08Z AT KCDS.

1132 AM CDT SUN JUN 3 2007

THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE EXTREME SOUTHERN TEXAS
PANHANDLE...SOUTH PLAINS AND ROLLING PLAINS.

.DAY ONE...THIS AFTERNOON AND TONIGHT

CONVECTIVE

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT ACROSS ALL OF THE SOUTH PLAINS...ROLLING PLAINS AND
EXTREME SOUTHERN TEXAS PANHANDLE.

A MOIST AND UNSTABLE AIRMASS WILL CONTINUE ACROSS WEST TEXAS THIS
AFTERNOON. SCATTERED THUNDERSTORMS WILL DEVELOP BY LATE AFTERNOON
AS A RESULT OF STRONG SURFACE HEATING AND AN APPROACHING UPPER
LEVEL DISTURBANCE. INITIAL STORM DEVELOPMENT WILL TEND TO FAVOR
OUTFLOW BOUNDARIES FROM THUNDERSTORMS SATURDAY NIGHT...WITH STORMS
EVENTUALLY EVOLVING INTO A SOUTHEASTWARD MOVING CONVECTIVE COMPLEX
DURING THE EVENING HOURS. HAIL UP TO THE SIZE OF GOLF BALLS AND
DAMAGING WIND GUSTS UP TO 70 MPH WILL BE POSSIBLE WITH ANY SEVERE
THUNDERSTORMS THAT DEVELOP. A FEW TORNADOES MAY ALSO OCCUR LATE
THIS AFTERNOON AND EARLY THIS EVENING...PARTICULARLY SOUTH OF A
LINE FROM MORTON TO LUBBOCK TO JAYTON.

FLOODING

HEAVY RAINFALL WILL OCCUR WITH ANY THUNDERSTORMS THAT DEVELOP.
SOME OF THE THUNDERSTORMS...PARTICULARLY LATE THIS AFTERNOON AND
EARLY THIS EVENING...WILL MOVE SLOWLY WHICH COULD RESULT IN
LOCALLY EXCESSIVE RAINFALL AND FLASH FLOODING. THE FLASH FLOOD
THREAT SHOULD DIMINISH LATE THIS EVENING AS THE STORMS INCREASE IN
SPEED.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY
SEVERE THUNDERSTORMS WILL BE POSSIBLE AGAIN MONDAY AND TUESDAY AS
LITTLE CHANGE IN THE WEATHER PATTERN IS ANTICIPATED. ONCE
AGAIN...LOCATIONS MOST FAVORABLE FOR SEVERE WEATHER WILL BE
DETERMINED BY RESIDUAL SURFACE BOUNDARIES THAT RESULT FROM STORMS
THAT DEVELOP TODAY AND AGAIN ON MONDAY.

.SPOTTER INFORMATION STATEMENT...

EMERGENCY MANAGERS AND LAW ENFORCEMENT PERSONNEL SHOULD BE
PREPARED FOR SEVERE THUNDERSTORMS AND SPOTTER GROUPS WILL LIKELY
BE ACTIVATED LATE THIS AFTERNOON AND EVENING.
