207 PM CDT FRI MAY 13 2005

.SHORT TERM...
NOT PLANNING ON MAKING MANY CHANGES TO THE GOING FORECAST. THE BEST
CHANCE FOR THE MOISTURE TO HOLD AND THE CAP TO BREAK ALONG THE DRYLINE
WILL BE IN THE BIG BEND...LOWER TRANS PECOS REGION AND THE SOUTHEAST
PERMIAN BASIN TO THE EXTREME WESTERN LOW ROLLING PLAINS THIS EVENING.
THE DRYLINE WILL PROBABLY COME TO A HALT IN THESE AREAS EARLY THIS
EVENING DUE TO DIURNAL AFFECTS AND A LAGGING WEAK SOUTHERN STREAM
700 MILLIBAR TROUGH APPROACHING FROM NEW MEXICO. ANY THUNDERSTORMS
THAT CAN FORM WILL HAVE THE POTENTIAL TO BECOME SEVERE BASED ON
SHEAR AND BUOYANCY PARAMETERS ALONG WITH VERY STRONG MOISTURE
DISCONTINUITY ALONG THE DRYLINE. BY LATER TONIGHT CONVECTION
TO THE NORTHEAST SHOULD CONTINUE TO TRANSLATE/FORM TOWARD THE EXTREME
WESTERN LOW ROLLING PLAINS AS THE MORE NORTHERN AND STRONGER
SHORTWAVE IN THE CENTRAL PLAINS IGNITES THE FRONT. BEST CHANCE POPS
OVERNIGHT WILL CONTINUE TO BE IN THE NORTHEAST COUNTIES CLOSEST TO
CONVECTIVE SYSTEM AND FRONT. VERY DRY AIR ACROSS WESTERN SECTIONS
DICTATE THAT THE RUC GUIDANCE DEW POINTS LOOK MOST REASONABLE EARLY
TONIGHT. WILL LEAN TOWARD THE ETA SURFACE WINDS OVERNIGHT AS THEY
HAVE BEEN VERIFYING THE BEST IN THE SHORT TERM TODAY AND USUALLY
DO BETTER WITH STRONGER COLD FRONTS. TWEAKED THE TEMPERATURE GRIDS.

.LONG TERM...
POWERFUL NRN STREAM SHRTWV TROF MOVING OUT OF NRN PLAINS SAT
AM WILL REENFORCE SFC HIGH ACRS PLAINS INSURING COLD FRONT
MOVES INTO RIO GRANDE VICINITY. SEVERAL FACTORS COME INTO PLAY
SAT THAT CONTINUE TO MAKE FORECAST DIFFICULT. FIRST NW MID LEVEL
FLOW WILL BE IN PLACE WITH ADVERTISED PRIMARY SHRTWV TROF MOVING
INTO NE NM LATE SAT PM AND MINOR SHRTWV ADVERTISED ACROSS PB.
NOT SURPRISING POST FRONTAL AIRMASS IS COOLER AND MORE STABLE
FARTHER NEWD. THUS BEST INSTABILITY IS EXPECTED TO FOCUS ACROSS
CENTRAL PB S AND W INTO TRANS PECOS. UPSLOPE FLOW AND STEEP MID
LEVEL LR/S AND CLEARING SKIES SUFFICIENT TO BE CONCERNED ABOUT
TSTM DEVELOPMENT DURING THE PM. GFS EXCITED ABOUT DEVELOPING A
LOWER TRANS PECOS COMPLEX LATE SAT PM/EARLY EVENING WITH NAM
SHOWING ONLY HINTS. ALSO POTENTIAL FOR COMPLEX TO COME OUT OF E
CENTRAL NM AND MOVE S INTO A MOIST SE LLJ. FCST ALREADY ACCOUNTS
FOR THIS WITH SCT POPS AND SEE NO REASON TO CHANGE ATTP. MORE
SHRTWV ENERGY SUNDAY AS NW FLOW BECOME MORE ORGANIZED WITH BETTER
MODEL AGREEMENT ON SHRTWV TROF. LOW LEVEL MST AXIS REMAIN PARKED
ACRS ERN NM WITH MUCH DRIER AIR TO E. THUS COMPLEX IS GREATLY
FAVORED TO MOVE S INTO SE NM AND TRANS PECOS SUNDAY. HAVE INCREASED
POPS TO SCT ACRS SE NM. MSTR REMAINS BACKED INTO MTNS MONDAY WITH
LACK OF UPPER SUPPORT INDICATED. SUFFICIENT MSTR/ LR/S / UPSLOPE
ENUF FOR ISOLD MTN POPS. FLAT RIDGING TUE AMPLIFIES INTO FRIDAY
THUS DRY AND ABOVE NORMAL TEMPS.
