AREA FORECAST DISCUSSION...ADDED NPW TO WATCH/WARNING SECTION...
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
524 AM CDT FRI MAY 19 2000

PRESSURE RISES OF A HALF TO 1 1/2MB PER HOUR PUSHING COLD FRONT
ACROSS PRESIDIO COUNTY AND THROUGH BIG BEND AT 07Z/19...WITH
BOUNDARY NEARLY STALLED NEAR K6R6.  SATELLITE IMAGERY INDICATING
SHORTWAVE OVER NORTHEAST ARIZONA TRANSLATING SLOWLY SOUTHEAST.
INCREASE IN ISENTROPIC UPGLIDE APPARENT ON SATELLITE IMAGERY OVER
SOUTHEAST CWA WHERE LOW CLOUDS DEVELOPING AND PRECIPITATION TRYING TO
DEVELOP.

DECENT UPGLIDE AT 305...310...AND 315K PROGGED TO CONTINUE ON ONE OR
MORE OF THESE SURFACES INTO SATURDAY.  COPIOUS MOISTURE JUST TO THE
SOUTH OF THE FRONTAL BOUNDARY WILL BE DRAWN BACK OVER COOLER AIRMASS
AS SHORTWAVE APPROACHES.  WILL INCLUDE POPS ACROSS MOST OF CWA AS
UPGLIDE AND LIFT ASSOCIATED WITH SHORTWAVE SHOULD BE ENOUGH TO
PRODUCE PRECIPITATION MOST AREAS.  LOW LEVEL MOISTURE ABOVE MOST
MODEL PROJECTIONS ALONG MOUNTAINS...SO WILL ALSO ADD CHANCE THERE FOR
TODAY.  FURTHER SOUTH...MODELS HINTING AT MCS DEVELOPING OVER
PORTIONS OF TEXAS AND NORTHERN MEXICO. ALTHOUGH UPPER FLOW IS NOT
EXACTLY DIFFLUENT...WEAK SHORTWAVE...LIFT IN RRQ OF EXITING 250 MB
JET...AND AROUND 30 KT LOW LEVEL JET INFLOW MAY BE ENOUGH FOR THIS TO
COME ABOUT.  THINK BIG BEND AREA WILL BE ON WESTERN FRINGE OF ANY
SUCH INITIATION AND WILL INCLUDE SLIGHT CHANCE THERE THIS EVENING...
WHILE TERRELL COUNTY IS PROBABLY GOING TO BE ON NORTHERN FRINGE SO
WILL DEAL THE SAME THERE.  WILL LEAVE SLIGHT CHANCE OF SHRA/TSRA
SATURDAY MOST LOCATIONS AS SOUTHEAST FLOW KEEPS MOISTURE OVER AREA
AND NEXT WEAK SHORTWAVE PASSES.

EXPECTED CLOUD COVER AND LOW LEVEL EAST FLOW SHOULD KEEP TEMPERATURES
DOWN MOST LOCATIONS AND WILL DROP MOST AREAS A CAT OR TWO...SOME A
LITTLE BIT MORE.  WILL USE COMPROMISE OF FWC/FAN TEMPERATURES FOR
REST OF SHORT TERM.

THE PRELIMINARY GUIDANCE BELOW IS FOR COORDINATION PURPOSES ONLY.
