AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
310 PM CDT FRI SEP 15 2006

.SHORT TERM...
SFC TROF EXTENDS N-S FM ERN NM INTO THE UPPER TRANS PECOS WITH
MSAS LI/S FROM NW PB INTO THE BIG BEND REGION. 25-30KTS OF BULK SHEAR
AND CAPES NEAR 100O J/KG SUGGEST STRONG/MARGINALLY SEVERE STORMS
POSSIBLE. W TX LOOKS TO BE IN RRQ AND WITH CONVERGENCE INVOF SFC TROF
ISOLD TSRA POSSIBLE INTO THE EVENING. DEVELOPMENT OF LLJ EARLY THIS
EVENING COULD PROLONG A FEW STORMS. OTHERWISE DWPNTS EXPECT TO
REMAIN UP OVERNIGHT...EXCEPT ACRS THE FAR W AND MORNING LOWS WILL
CONTINUE TO TREND UP.

.LONG TERM...
UPPER LOW MOVING INTO NRN HIGH PLAINS SAT HAS BROAD CYCLONIC FLOW
CARVED OUT ACRS WRN 1/2 OF CONUS. ASSOCD SFC TROF WILL BE WELL
ESTABLISHED ACRS PLAINS. IN FACT A DOWNSLOPE COMPONENT IS EXPECTED
FROM UPPER TRANS PECOS INTO SE NM AND WITH THERMAL RIDGE TEMPS
WILL BE WELL ABOVE NORMAL. ATTENTION OF FCST IS STILL FOCUSED ON
REMNANTS OF LANE AND ASSOCD MSTR MOVING INTO NRN MEXICO LATE
SAT-MON. OFFICIAL TRACK OF LANE TAKES IT THRU SRN BAJA REGION
MAKING LANDFALL ALONG THE MEXICAN COAST ONLY 400 MILES FROM
PRESIDIO MON A.M.. MID LEVEL SLY FLOW ACRS MEXICO WILL FEED MSTR
NWD INTO BIG BEND REGION AS EARLY AS SAT PM (ALREADY EVIDENT ON
WATER VAPOR). TYPICALLY...SUSTAINED SLY MID LEVEL FLOW RESULTS IN
RAIN ACRS BIG BEND/LOWER TRANS PECOS. BY THE END OF SAT PW/S
SHOULD BE AS HIGH AS 1.5 AND WILL TREND POPS UP SAT PM ACRS FAR
FAR S-SW. MEANWHILE COLD FRONT WILL MOVE S INTO NRN PB SUN WITH
SFC DWPNTS DECREASING DURING THE DAY ACRS SE NM/NRN CWFA. AS SUCH
SKEPTICAL THAT PRECIP WILL HAVE A CHANCE TO DEVELOP ACRS W-N
CWFA...COOLER AS WELL. MSTR WILL REMAIN ACRS BIG BEND/LOWER TRANS
PECOS SUNDAY. EVEN THOUGH LANE WILL STILL BE WELL W THERE S/B A
GOOD CHANCE OF RAIN AND MAY TREND POPS UP A LITTLE. MEANWHILE
BROAD MID LEVEL CYCLONIC FLOW WILL TRANSITION E WHICH WILL PUSH
MST AXIS E AND S...THEREBY KEEPING THE CHANCE OF RAIN ACRS THE PB
MINIMIZED. THIS TOO SUGGEST MSTR WILL BE PUSHED FARTHER S AND E
THRU MEXICO AS EARLY AS MONDAY RESULTING IN A SHORTER PERIOD OF
HEAVY RAIN ACRS BIG BEND/LOWER TRANS PECOS. AS MID LEVEL TROF
MOVES E FRONT SHOULD BE ABLE TO MOVE S INTO THE TRANS PECOS MON
P.M.. ECMWF INDICATES FRONT AS FAR S AS RIO GRANDE LATE MON P.M..
OF COURSE UNCERTAINTY IN REGARD TO HOW REMNANTS OF LANE ARE
INCORPORATED INTO WLY FLOW. NHC PRODUCTS INDICATE A SLOW MOVEMENT
REFLECTING DIFFICULTIES IN RESOLVING TRACK AFTER LANDFALL. GFS
MODELS CONTINUE TO SHOW LARGE CHANGES FROM YESTERDAY/S RUN WITH
STRONGER WLY MID LEVEL FLOW DEVELOPING ACRS SWRN STATES. A QUICK
LOOK AT LATEST INDICATES ECMWF LEANING THAT WAY TOO. STRONGER MID
LEVEL FLOW WILL FAVOR LEE TROFFING AND THERMAL RIDGING WED-FRI.
ATTP HAVE LOST CONFIDENCE IN MODEL SOLUTIONS AND EXPECT TO MAKE
LITTLE CHANGE IN LATTER PERIODS. UP SHOT IS THAT BEST CHANCE OF
RAIN WILL OCCUR SAT-MON ACRS FAR S WITH HEAVY RAIN POSSIBLE
ALTHOUGH NOT AS FAVORABLE AS YESTERDAY/S DATA.

&&

.HYDROLOGY...
RIVER LEVELS REMAIN ELEVATED ALONG THE RIO GRANDE DUE TO RELEASES
FROM LUIS LEON RESERVOIR IN MEXICO...AND FROM RAINFALL RECEIVED
FURTHER UPSTREAM ALONG THE RIO GRANDE.  SINCE MOISTURE FROM TROPICAL
STORM LANE HAS ALREADY BEGUN TO MOVE NORTHWARD THROUGH MEXICO...IT
APPEARS THE CHANCE OF HEAVY RAIN WILL BE ON THE INCREASE OVER MEXICO
AND WEST TEXAS SATURDAY THROUGH MONDAY. THEREFORE...HIGHER RIVER
LEVELS ALONG THE RIO GRANDE ARE POSSIBLE AS ANY HEAVY RAINFALL
ALONG THE RIO GRANDE OR ITS TRIBUTARIES WILL RAISE RIVER
LEVELS. THOSE WHO HAVE INTERESTS ALONG THE RIO GRANDE RIVER IN
SOUTHWEST TEXAS SHOULD KEEP ABREAST OF THE LATEST FORECASTS...AND
RIVER FORECASTS...FROM THE NATIONAL WEATHER SERVICE.
