MAIN PROBLEM CONTINUES TO BE PCPN CHANCES.

DID TIME/HEIGHT CROSS SECTION OF VORT ADVECTION AND ALL MODELS HAD
INCRG PVA WITH HGT ABOUT 00Z-06Z FOR UPCOMING NIGHT. THIS SEEMS TO
AGREE WITH PROGRESS OF WAVE WATER VAPOR CURVE NOW SHOWS PUSHING INTO
MONTANA. THIS IMPLIES FRONT TO OUR S TO RETREAT N SOMEWHAT TODAY AS
WAVE CAUSES PRESSURE FALLS.

HOWEVER...LATEST SFC ANALYSIS HAS BEST PRES FALLS STILL WELL TO
SOUTH OF GLD AREA. LOOKS LIKE NGM SOLN WORKING OUT BETTER THAN ETA
WHICH IMPLIES FRONT ONLY ARRIVING OVR SE PTNS CWA TODAY. WITH HIGH
MOISTURE AVAIABLE ON WARM SIDE OF FRONT GOING WITH A PRETTY SHARP
POP GRADIENT FROM SE TO NW...ESPECIALLY TNGT WHEN SHORT WAVE WILL BE
AROUND.

FOR TEMPS...WILL ALSO GO WITH SE TO NW GRADIENT. GENERALLY EXCEEDING
GUIDANCE TODAY. THIS BECAUSE MESO/RUC MODELS DON'T INCREASE
HUMIDITIES OVR 70 PER BY 12Z THIS MORNING AND CURRENT TEMP/DEWPOINT
SPREADS HIGHER THAN AT SAME TIME YESTERDAY. THUS NOT TOO MUCH CLUDS
TODAY...AND WITH SUN OUT GUIDANCE LOOKS A LITTLE LOW BASED ON WHERE
OUR AIR WAS YESTERDAY. FOR TMRW BELOW GUIDANCE BASED ON TRAJS AND
TENDENCY OF MOS NOT TO MAINTAIN ENOUGH TEMP GRADIENT ACROSS FRONTS.
