THIS MORNING OVER ALL BUT FAR EASTERN UTAH...WHERE A FEW WEAK
THUNDERSTORMS HAVE DEVELOPED IN ASSOCIATION WITH A WEAK WAVE.

PACIFIC NORTHWEST COAST...ONE TODAY AND ONE TUESDAY
NIGHT/WEDNESDAY MORNING.

MODELS INDICATE THAT 700 MB TEMPS WILL RISE INTO THE +16 TO +18C
RANGE TODAY AND TOMORROW...SO TEMPERATURES SHOULD RUN AROUND 5F
ABOVE CLIMO. WITH MORE SOUTHWEST FLOW...MAXES SHOULD BE WARMER
STILL...PARTICULARLY OVER NORTHERN UTAH.

THE SECOND TROUGH IS EXPECTED TO GRAZE NORTHERN UTAH ON
WEDNESDAY...BUT WITH PWS RUNNING AT 0.30 OR BELOW...HALF OF THE
AVERAGE VALUE FOR THIS TIME OF YEAR...THERE SHOULD BE LITTLE IF
ANY THUNDERSTORM ACTIVITY. THE SYSTEM WILL BRING A DRY COLD FRONT
WITH IT...HOWEVER...WHICH SHOULD BRING TEMPS DOWN TO AROUND
SEASONAL NORMS OVER SOUTHERN UTAH AND A FEW DEGREES BELOW THOSE
VALUES OVER THE NORTH.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.
