...BIGGEST PROBS THIS FCST PCKG IS TIMING OF DYNAMICS...

MODELS WERE IN DECENT AGREEMENT THIS AM. NGM SEEMED TO HAVE BETTER
HANDLE ON SFC FEATURES...ESP WITH LEE TROF. HWVR...ETA DID MUCH
BETTER WITH UPPER LEVEL DYNAMICS. ONLY PROBLEM IS THE STRENGTH OF
THE NEXT SHWV COMING OUT OF GRT BASIN. SAT WV IMAGERY PICKS UP
SHWV WELL BUT MODELS DONT SEEM TO HAVE A HANDLE ON IT...SO TIMING IS
VERY UNCERTAIN. EXPECT SHWV TO MV THRU FA TONIGHT WITH WK COLD
FNT...WITH TSTMS PSBL ACROSS FA THIS EVE INTO TONIGHT. SOME SVR
PSBL IN ERN ZONES BUT EXPECT ONLY MARGINAL ELSEWHERE.

LIKED ETA DYNAMICS INTO TMRW AND OUT PDS AS STRONGER SHWV BEGINS TO
SLIDE DOWN BACKSIDE OF WK RIDGE. EXPECT GOOD PVA AHEAD OF SYS DURING
DAY TOMORROW. FA STAYS IN RIGHT REAR QUAD OF 300 MB JET SO SYNOPTIC
LIFT SHUD BE ENHANCED. MSTR SHUD STAY IN PLACE BEHIND WK FNT AND
SOME UPSLOPE WITH NE WINDS WILL HELP FORM MORE WIDESPREAD TSTMS.
AGAIN...QUESTION IS TIMING. FEEL TSTMS WILL CONT ACROSS FA INTO TMRW
NGHT BUT SHUD DISSIPATE AS NVA WORKS IN. GOOD SUBSIDENCE IN 750-300
Q-VECT CNVRG AND LESS MSTR SO SHUD EXPECT MILD BUT COOLER CONDS IN
4TH PD.

STAYED CLOSE TO FWC THRU ALL BUT 4TH PDS. FWC HAS BEEN TOO COOL PAST
FEW DAYS WITH 4TH PD SO FOLLOWED TREND. OTHERWISE...ONLY DEVIATED A
DEGREE OR TWO.
