AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
321 PM CDT SUN SEP 26 2004

.SHORT TERM...
WIDESPREAD SHOWERS AND ISOLATED TSTMS CONTINUE OVER THE WESTERN
THIRD OF THE AREA THIS AFTERNOON...IN AREA OF ISENTROPIC LIFT...DEEP
MOISTURE...HIGH PRECIPITABLE WATER VALUES...AND DYNAMIC LIFT FROM
UPPER LOW. SEE NO REASON FOR THIS PATTERN TO CHANGE AS UPPER LOW IS
PROGGED TO MOVE VERY SLOWLY EAST INTO SW TEXAS BY MONDAY NIGHT/EARLY
TUESDAY. BEST LIFT WILL REMAIN OVER SW COUNTIES OF THE SOUTH PLAINS
AND POINTS SOUTH AND WEST INTO THE PERMIAN BASIN AND EASTERN NEW
MEXICO. COULD SEE SEVERAL ROUNDS OF RAIN NEXT 36 HOURS AS DEEP EAST
TO SOUTHEAST FLOW CONTINUES TO KEEP COLUMN SATURATED...AND PROVIDE
FOR UPSLOPE BOUNDARY LAYER FLOW.

FEEL THAT MOST OF THE ACTIVITY WILL BE SHOWERY...AND WITH CLOUDY
CONDITIONS PREVAILING OVER THE WESTERN 2/3 OF THE FORECAST
AREA...LITTLE THUNDER EXPECTED. THIS HAS BEEN THE CASE TODAY...
WITH LIMITED SURFACE BASED INSTABILITY AND 700-500 MB LAPSE RATES
AROUND 6 DEG C/KM. HAVE SEEN PROBLEMS IN CASTRO COUNTY WITH ROAD
CLOSURES AND HEAVY RAIN COCHRAN AS WELL. RAINFALL RATES ASSOCIATED
WITH THE MORE INTENSE SHOWERS HAVE BEEN AT LEAST 1 TO 2 INCHES PER
HOUR...WITH 0.40 INCHES IN 5 MINUTES AT THE MESONET SITE NEAR
DIMMITT. WITH NW MOVEMENT OF CELLS...AND LINES OF CONVECTION
DEVELOPING NW-SE...TRAINING OF ECHOES IS BECOMING A PROBLEM. WILL GO
WITH FLASH FLOOD WATCH FOR EASTERN 2 ROWS OF COUNTIES FOR
TONIGHT...WITH THE POTENTIAL FOR CONTINUED REDEVELOPMENT OF HEAVY
RAIN.

DAYTIME TEMPERATURES WILL STAY COOL ESPECIALLY OVER THE WEST MONDAY.
LIKELY TO CATEGORICAL RAIN CHANCES TONIGHT THROUGH MONDAY NIGHT...
WITH CHANCE POPS EAST AND NORTHEAST.

.LONG TERM...
FEW CHANGES TO GRIDS BEYOND MON AS ACTIVE PATTERN REMAINS IN PLACE
FOR THE SPLNS. TSTM CHANCES WILL REMAIN ACROSS THE AREA ON TUE AS
UPPER LOW BEGINS TO FINALLY LIFT OUT TO OUR SOUTH JUST AS A COLD
FRONT WILL BACKDOOR INTO THE AREA FROM THE CENTRAL
PLAINS...REINFORCING NE LOW-LVL FLOW AND PROVIDING A FOCUS FOR
TSTMS. AREA WILL SEE DEEP EASTERLY FLOW NORTH OF THE LOW UP TO H5.

AS TROF AND SFC RIDGE MOVE TO THE EAST ON WED SHTWV RIDGING AND
SOUTHERLY FLOW WILL RETURN. THIS WILL ALLOW TEMPS TO WARM UP CLOSER
TO SEASONAL NORMS...70S AND LOWER 80S. CANNOT RULE OUT SOME TSTM
ACTIVITY AS WET SOIL AND MOIST ATMOS LEADS TO SOME CONVECTIVE
POTENTIAL...IF WE CAN GET SUFFICIENT HEATING.  HOWEVER...WITH
PROJECTED MID-LVL SUBSIDENCE THINKING IS ACTIVITY WILL REMAIN
ISOLD.

UPR TROUGH/CLOSED LOW OVER THE DESERT SW IS FCST TO APPROACH THE
AREA ON THU. SCT CONVECTION MAY BREAK OUT IN DIFFLUENT MOIST FLOW
AHEAD OF THE TROUGH. DETAILS ON HOW THIS SYS WILL EJECT ACROSS THE
ROCKIES AND INTERACT WITH A STRONG SYS DROPPING OUT OF THE NRN
PLAINS INTO THE OHIO VALLEY FOR THE WEEKEND ARE STILL SKETCHY AS
MODEL GUIDANCE DIVERGES QUITE A BIT IN THIS COMPLICATED PATTERN.
UPSHOT IS THAT A COLD FRONT WILL APPROACH THE SPLNS ON FRI...PASSAGE
THRU THE AREA FRI NIGHT/SAT MORN DEPICTED IN GRIDS. THE COLD FRONT
APPEARS TO HAVE STRONG ANTICYCLONE BEHIND IT BUILDING DOWN THE EAST
SIDE OF ROCKIES...SO COOL TEMPS LOOK TO BE IN STORE FOR THE WEEKEND.
