AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
320 PM MDT SAT SEP 1 2007

.DISCUSSION...

A RIDGE OF HIGH PRESSURE POSITIONED OVER THE SOUTHWEST U.S. IS
PROVIDING WARM AND MAINLY DRY WEATHER TO THE AREA TODAY. SATELLITE
INDICATES A FEW CUMULUS BUILDUP AROUND THE REGION ALTHOUGH RADAR HAS
NOT DETECTED ANY THUNDERSTORM ACTIVITY YET. THERE IS STILL A FEW
MORE HOURS OF HEATING TO GO AND SO THE THREAT FOR AN ISOLATED
THUNDERSTORM STILL EXISTS.

OTHERWISE...THE RIDGE WILL REMAIN THE MAIN WEATHER FEATURES OVER
THE NEXT COUPLE OF DAYS. THIS WILL PRODUCE CONTINUED WARM WEATHER
WITH MAINLY DRY CONDITIONS ACROSS THE REGION. THE BETTER MOISTURE
WILL REMAIN SOUTH OF THE AREA...PERHAPS MAKING SOME INROADS ON
MONDAY. AS A RESULT...CHANCES FOR THUNDERSTORMS WILL REMAIN RATHER
SLIM.

ON TUESDAY...A STRONG COLD FRONT ASSOCIATED WITH A SIGNIFICANT UPPER
LEVEL TROUGH IS EXPECTED TO ARRIVE. THIS SYSTEM WILL BRING THE
BEST CHANCES FOR SHOWERS AND THUNDERSTORMS TO THE REGION TUESDAY
AFTERNOON. MODELS CONTINUE TO BE OUT OF SINK IN HANDLING THE
TIMING OF THIS TROUGH. AS A RESULT...RAIN CHANCES NOW LINGER INTO
WEDNESDAY. MUCH COOLER WEATHER IS EXPECTED FOR WEDNESDAY AND
BEYOND AS NORTHWEST FLOW DOMINATES THE AREA. WILL HAVE TO CONTINUE
TO MONITOR THE MOISTURE ASSOCIATED WITH TROPICAL STORM
HENRIETTE...THE LATEST GFS RUN CARRIES THIS MOISTURE WELL SOUTH
AND EAST OF THE REGION.
