...SHORT TERM...
MAIN QSTN TNGT IS POPS ANBD TEMPS.  ELEVATED BAROCLINIC ZN SET UP
ACRS MY FA SHD SHOW LTL MOVEMENT TNGT WITH UPSLOPE FLOW AGAINST HIER
TERRAIN OF COLORADO DUE TO PRODUCE ANOTHER MCS WHICH SHD TRACK SE
DOWN THE BAROCLINIC ZN ACRS MY ZNS.  MDLS AGREE ON THIS WITH
EXCEPTION THAT THEY SHOW USUAL BIAS FOR MOVG THE FNT AND BAROCLINIC
ZN BACK TO THE NORTHEAST TOO FAR AND TOO FAST.  MOST AREAS WILL SEE
RAIN IN THE BUCKET THUS WILL GO WELL ABV MOS FOR POPS AND WITH HIGH
DWPTS WILL ALSO CONTINUE MNTN OF PSBL LCLY HVY RAINS.  FWC TEMPS
LOOK FAIRLY GOOD BUT WL UNDERCUT THEM JUST A TOUCH FOR EVAPORATIVE
COOLING IN COOL AIRMASS.

...LONG TERM...
WYSIWYG. THO MDLS PUSH BAROCLINIC ZN OFF TO THE NE WITH TIME HARD TO
SEE HOW THIS WL HAPPEN AS CONTD CHCS FOR PCPN FALLING INTO THE COLD
AIR EACH AFTN AND EVE SHD CONT TO REINFORCE THE COLD AIR DOME AND
THUS KEEP THE FRONT ND BAROCLINIC ZN FARTHER S INCREASING THE DAILY
AND NIGHTLY RISK FOR PCPN.  WL GO SIGNIFICANTLY ABOVE GUIDANCE FOR
POPS EACH DAY AND OVRNGT AND A CATEGORY BLO GUIDANCE FOR HIGH TEMPS.
MOS LOOKS RSNBL FOR OVRNGT LOWS WITH ONLY MINOR TWEEKS NEEDED.

...EXTENDED...
TODAYS EXTENDED MODELS ARE STARTING TO SHOW AN INCREASE TO THE
MONSOONAL FLOW OVER THE CWA FOR THE WEEKEND PERIOD. ALSO...THIS
MORNINGS 12Z AVN AND LAST NIGHTS MRF ARE HINTING AT SOME SORT OF
TROPICAL DISTURBANCE TRYING TO NOSE ITS WAY UP CENTRAL TEXAS DURING
FRIDAY/SATURDAY. IF THAT DISTURBANCE CAN GET CAUGHT UP IN THE
ADVERTISED SOUTHWEST FLOW...THEN A CHANCE FOR PCPN FOR THE WEEKEND
SEEMS VERY REASONABLE. LOWS AND HIGHS THROUGHOUT THE PERIOD WILL BE
LOWERED SLIGHTLY GIVEN THIS SCENARIO.
