.LONG TERM...WEDNESDAY NIGHT THROUGH NEXT TUESDAY...
UNSETTLED/ACTIVE PATTERN TO REMAIN IN PLACE WITH MAIN FOCUS ON NEXT
STORM IN HIT PARADE LATE WEEK AND EARLY IN THE WEEKEND. CHALLENGES
ABOUND WITH THIS STORM WITH USUAL TRACK...INTENSITY AND TIMING...
ALL OF WHICH TO HAVE BIG IMPACT ON PCPN TYPE/AMOUNTS. PATTERN AND
ENERGETICS CONDUCIVE FOR MODERATE TO LOCALLY HEAVY QPF. MODEL TRENDS
OF LATE HAVE BEEN TO TAKE SYSTEM FURTHER SOUTH. THIS WOULD INVITE
MORE COLD AIR THUS INCREASING POTENTIAL FOR SNOW OR RAIN/SNOW
MIX...ESPECIALLY NORTH HALF. OVERALL THOUGH... VERY LOW CONFIDENCE
ON DETAILS OF SYSTEM WITH IMPACTS FROM INITIAL SYSTEM TONIGHT-WED...
BUT HARD TO IGNORE SOUTHERN TRENDS AND HAVE STARTED TO TREND COLDER
ON TEMPS AND INTRODUCE RAIN/SNOW MIX TO NORTH. TREND OF LATE HAS
ALSO BEEN TO SLOW DOWN THE STORM WHICH IS COMMON WITH THESE
SOUTHWEST SYSTEMS. HAVE THEREFORE REMOVED POPS UNTIL FRI AFTN... BUT
IF SLOWING TRENDS PERSIST WHICH I BELIEVE WILL BE THE CASE THEN PCPN
MAY NOT ARRIVE UNTIL LATE FRI NIGHT AND ESPECIALLY SAT/SAT NIGHT.
BEYOND WEEKEND MEDIUM RANGE MODELS SUGGEST OMEGA BLOCK DEVELOPING.
WHEN THAT BLOCK BREAKS DOWN WILL DETERMINE NEXT PCPN THREAT.

AS FOR TEMPS... GENERALLY UNDERCUT MEX GUIDANCE THROUGHOUT. POTENTIAL TO BE
COLDER ESPECIALLY THURS-FRI WITH NEGATIVE FEEDBACK FROM FRESH SNOW
COVER NORTH AND WET GROUND ELSEWHERE...AND WITH SFC RIDGE BUILDING IN.
