AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
342 PM CST TUE JAN 15 2002

SIG WX NIL UFN.  NOT MUCH HAS CHANGED IN THE OVERALL REASONING SINCE
24H AGO.  THE UPPER FLOW REGIME OVER NOAM WILL BE CHARACTERIZED BY
A BROAD LONGWAVE TROUGH OVER THE NEXT SEVERAL DAYS.  EMBEDDED WITHIN
THIS LONGWAVE TROUGH WILL BE A PERSISTENT EMBEDDED POSITIVELY TILTED
SHORTWAVE TROUGH EXTENDING FROM CALIFORNIA NORTHEAST INTO SOUTHERN
CANADA.  SEVERAL WEAK DISTURBANCES MOVING OUT OF THIS FEATURE WILL
RESULT IN A FEW SOUTHWARD PENETRATIONS OF MODIFIED CANADIAN AIR...BUT
GIVEN THAT THERE IS PRACTICALLY NO SNOWPACK ACROSS THE PLAINS AND
THAT THIS FLOW REGIME LENDS ITSELF TO QUICK REDEVELOPMENT OF THE
SURFACE LEE TROUGH...LITTLE SIGNIFICANT CHANGE TO TEMPERATURES IS
FORECAST THROUGH EARLY NEXT WEEK.

OVER THE SHORT TERM...EXTENSIVE MID AND HIGH LEVEL MOISTURE WILL
PERSIST ACROSS THE REGION.  THIS WILL SERVE TO NARROW THE DIURNAL
SPREAD SOMEWHAT...RAISING OVERNIGHT MINIMA AND LOWERING DAYTIME
MAXIMA FROM WHAT GUIDANCE SUGGESTS.  A WEAK COLD FRONT IS FORECAST TO
DROP INTO NORTHERN ZONES WEDNESDAY NIGHT...BUT THIS FEATURE SHOULD
DISSIPATE AND TRANSLATE AWAY FROM THE AREA THURSDAY.  A PIECE OF
ENERGY BECOMES DISLODGED FROM THE POSITIVELY TILTED TROUGH FRIDAY
INTO SATURDAY AS ANOTHER SHORTWAVE TOPS THE EASTERN PACIFIC RIDGE AND
DROPS INTO THE MEAN TROUGH POSITION.  WHILE THERE WILL BE SOME
DYNAMICAL SUPPORT AND CONSIDERABLE UPPER MOISTURE TO WORK WITH...THE
LOW LEVEL MASS FIELDS DONT LOOK SUPPORTIVE OF SUBSTANTIAL GULF
MOISTURE RETURN.  FURTHERMORE...A WAVE TRANSLATING ACROSS THE GULF
THIS AFTERNOON WILL MAINTAIN SOME RIDGING ALONG THE GULF COAST...
THEREBY KEEPING WHAT MOISTURE RETURN THERE IS CONFINED TO AREAS WELL
EAST OF THE CWFA.  THUS THE CHANCES OF MEASURABLE PRECIP EARLY THIS
WEEKEND ARE SLIM AND NONE.  WE WILL MAINTAIN MOSTLY CLOUDY SKIES
THROUGH SATURDAY AS WE SHOULD SEE THE HIGH LEVEL PACIFIC MOISTURE
REMAINING WITHIN THE SUBTROPICAL JET...WITH PERHAPS SOME CLEARING
AFTER TROUGH PASSAGE SATURDAY.  THE EXTENDED SHOULD REMAIN DRY UNDER
A CONTINUANCE OF THE FAST ZONAL FLOW ALOFT...AND TEMPERATURES SHOULD
REMAIN AT OR A BIT ABOVE CLIMATOLOGY THROUGH THE MIDDLE OF NEXT
WEEK.

THE PRELIMINARY GUIDANCE BELOW IS FOR COORDINATION PURPOSES ONLY.
OFFICIAL FORECASTS ARE CONTAINED WITHIN THE WEST TEXAS/SOUTHEASTERN
