...FORECAST PROBLEMS WILL BE CHANCE OF PCPN TONIGHT AND TEMPS THRU
PD...

A COMPLICATED FCST MADE MORE MESSY BY INDIVIDUAL MODELS NOT CATCHING
DETAILS IN DIFFERENT AREAS. BASED ON INITIAL ANALYSIS...CURRENT
TRENDS ON SATL...SFC...AND PROFILER WINDS...AND PREV PERFORMANCE...AM
GOING TO BLEND THE MODELS. ETA IS DOING BETTER WITH LWR LEVELS.
HWVR...NGM/AVN ARE DOING MUCH BETTER WITH MSTR/PCPN ALONG WITH
FEATURES FROM 700 MB TO JET LEVEL. ALL MODELS ARE TOO DRY...
ESPECIALLY NR THE SFC...WITH ETA DRIEST WITH AVN IN THE MIDDLE. BASED
ON DPS AND COPIOUS AMOUNTS OF SUBTROPICAL MSTR COMING IN ON
SATL...LIKE THE NGM THERE.

VERY STRONG UPR SYSTEM MOVG OUT OF DESERT SW PER SATL. ALSO 200 MB
JET AND AGEO FORCG...AND HIGH LAPSE RATES ARND THRU THE NIGHT. SFC
ANAL SHOWS SOME KIND OF LOW LVL BOUNDERY DRAPED EAST TO WEST JUST
SOUTH OF OUR CWA. AVN/NGM HANDLE THE UPR SYSTEM BEST. BASED ON ALL
FACTORS...BEST FRCG/VORT AND CHC OF PCPN LOOK TO BE OVR SRN AND ERN
CWA AND WL PUT HIGHEST POPS THERE. WL TAPER OFF 30 TO 40 PERCENT IN
CNTRL AND NW LOCATIONS.

COULD BE SOME LINGERING PCPN IN ERN CWA AND WL KEEP CHC IN THERE
THROUGH THE DAY. AM NOT COMFORTABLE WITH MODELS HANDLING S/WS IN
THIS FLOW ALOFT. EVEN THOUGH SHOULD DRY OUT BEHIND TONIGHTS
FEATURE...LOOKS TO BE ENUF INSTABILITY...MSTR...AND LIFT TO KEEP A
SLIGHT CHC IN 2ND AND 3RD PD.

850 TEMPS LOOK TO STAY NRLY THE SAME THRU PD. WL HAVE ENOUGH
DYNAMICS ARND TO KEEP SOME CLDS PLUS COULD HAVE SOME WET GRND IN SRN
AND ERN AREAS. WINDS GO TO NEUTRAL TO UPSLOPE IN 3RD AND 4TH PDS.
BASED ON ALL THIS...WL TEND TO GO CLOSE TO NGM MOS WITH GOING
SLIGHTLY BLO 3RD AND 4TH PDS.

.GLD...NONE.
