AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
255 PM MDT FRI JUL 6 2007

.DISCUSSION...MIDLEVEL MOISTURE IS SURGING NORTHWARD INTO
SOUTHWEST MONTANA AND EAST CENTRAL IDAHO KICKING OFF ISOLATED
THUNDERSTORMS. THIS AND EXPECTED BREEZY WINDS LATER THIS
AFTERNOON AND EVENING WILL PRODUCE FIRE WEATHER CONCERNS. A RED
FLAG WARNING HAS BEEN POSTED. CONVECTION SHOULD CONTINUE OVER THE
REGION THROUGH THE EVENING HOURS AND BE CONFINED TO CENTRAL
IDAHO SOUTHWEST AND WEST CENTRAL MONTANA AND DIE OFF LATE THIS
EVENING. THE STRONG RIDGE WHICH HAS PRODUCED RECORD TEMPERATURES
THE PAST 2 DAYS WILL BEGIN TO BREAK DOWN THIS EVENING AS A WEAK
SHORT WAVE NOSES ITS WAY INTO NORTHWEST MONTANA OVERNIGHT.

SATURDAY THE WEAK WAVE WILL MOVE THROUGH SOUTHWEST MONTANA AND
EAST CENTRAL IDAHO. MID LEVEL MOISTURE CONVERGENCE AND DYNAMIC
SUPPORT WILL FORM CONVECTION TOMORROW AFTERNOON AND EVENING. STORMS
THAT DEVELOP WILL BE MAINLY DRY EARLY WITH SOME CONTAINING RAIN BY
EVENING. INCREASING PRESSURE GRADIENTS WITH FRONTAL PASSAGE WILL
INCREASE WINDS IN THE AFTERNOON. THIS COMBINATION OF WIND AND
THUNDERSTORMS WILL CREATE POSSIBLE FIRE WEATHER CONCERNS.
DEPENDING ON THE SPEED OF THE FRONTAL PASSAGE NOCTURNAL
THUNDERSTORMS COULD BE A CONCERN...BUT ARE NOT EXPECTED AT THIS
TIME AS MODELS MOVE THIS THROUGH BY EVENING. A FIRE WEATHER WATCH
HAS BEEN POSTED SATURDAY. TEMPERATURES WILL COOL ABOUT 10 DEGREES
SATURDAY.

ZONAL TO SLIGHTLY NORTHWESTERLY FLOW WILL PREVAIL OVER THE
NORTHERN ROCKIES SUNDAY THROUGH TUESDAY. THIS FLOW PATTERN WILL
USHER IN SLIGHTLY COOLER TEMPERATURES (THOUGH STILL IN THE UPPER
80S TO LOW 90S) AND SOME MID AND HIGH LEVEL CLOUD COVER. THIS WILL
BE SHORT LIVED HOWEVER AS MODELS CONTINUE TO INDICATE ANOTHER
STRONG RIDGE OF HIGH PRESSURE BUILDING OVER THE AREA WEDNESDAY.
ANOTHER BOUT OF HIGH TEMPERATURES (MID TO UPPER 90S) IS EXPECTED
BY THE END OF THE WEEK. CURRENT PLACEMENT OF THIS RIDGE
HOWEVER...SEEMS TO FAVOR MORE MOISTURE IN THE UPPER LEVELS AND
THUS THE POTENTIAL FOR AFTERNOON THUNDERSTORMS BY LATE WEEK.
