AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
300 PM MDT FRI JUL 6 2007

.SHORT TERM...TONIGHT THROUGH SUNDAY.
CONVECTION HAS DEVELOPED IN CENTRAL MOUNTAINS AND JUST WEST OF THE
SOUTH CENTRAL HIGHLANDS.  HAVE NOT SEEN ANY LIGHTNING STRIKES YET.
EXPECT A MIXTURE OF WET AND DRY THUNDERSTORMS WITH THIS TONIGHT AS
STILL VERY DRY IN LOW LEVELS BUT DEWPOINTS HAVE RISEN TODAY A BIT.
BASICALLY A LOT OF MID AND HIGH LEVEL MOISTURE HAS MOVED INTO SE
IDAHO UNDER THE RIDGE AS IT SLIDES EAST AND STARTS TO FLATTEN AS
FAIRLY STRONG WAVE MOVES EAST TODAY INTO NORTHERN CALIFORNIA RIGHT
NOW AND THIS WAVE WILL SLIDE THROUGH SOUTHERN IDAHO DURING THE DAY
ON SATURDAY.  WITH THIS WAVE INCREASED THUNDERSTORM CHANCES TO
INCLUDE ALL OF SOUTHEAST IDAHO WITH A MIXTURE OF WET AND DRY AGAIN
ON SATURDAY.  AFTER THIS WAVE GOES THROUGH FLOW GOES ZONAL ON SUNDAY
AND THINK WILL DRY OUT SOME BUT LEFT ISOLATED THUNDERSTORMS IN
EASTERN AND SOUTHERN HIGHLANDS.  WINDS SHOULD INCREASE IN SNAKE
PLAIN SATURDAY AFTERNOON AS CALIFORNIA SHORT WAVE WILL DRIVE THROUGH
WEAK COLD FRONT.  TEMPERATURES SHOULD BE ANYWHERE FROM 5 TO 10
DEGREES COOLER ON SATURDAY THAN TODAY.
GK

WERE ALLOWED TO CONTINUE AND ZONE 412 WAS ADDED TO THE MIX AS WELL

POTENTIAL TO SEE SOME STORMS WORK OFF THE SRN HIGHLANDS THIS EVENING
AND WILL CONTINUE TO MONITOR THIS AS A POTENTIAL UPDATE THIS
AFTERNOON. ALLOWED ZONE 413 TO CONTINUE AS A WARNING THIS AFTERNOON
AS UPSTREAM DEVELOPMENT OVER NE UTAH MAY BE EVIDENT OF INSTABILITY
OVER REGION AND POTENTIAL THUNDERSTORM DEVELOPMENT IN THE CARIBOU
NF. LOOKING TOWARDS SATURDAY...A DISTURBANCE ALONG THE CALIFORNIA
COAST WILL ROTATE OVERHEAD BY SATURDAY AFTERNOON SUPPORTING BEST DRY
THUNDERSTORM POTENTIAL ACROSS THE REGION SO FAR THIS SEASON. SPEED

WRN ZONES AND WILL ALLOW WATCH TO CONTINUE FOR NOW UNTIL WARNING
THIS EVENING EXPIRES AND THEN WILL LOOK AT UPGRADING HIGHLIGHTS FOR
