.DISCUSSION...THIS AFTERNOON THROUGH MONDAY NIGHT. THE FIRST OF
TWO STRONG SHORT WAVE TROUGHS WILL MOVE TO THE NE ACROSS THE AREA
LATE THIS AFTERNOON AND EVENING BRINGING SCATTERED THUNDERSTORMS.
STORMS WILL INITIALLY START OFF AS A MIX OF WET AND DRY...BUT WILL
MOISTEN UP IN THE EVENING AS THE WAVE MOVES ACROSS WEST CENTRAL
AND SW MT. CONVECTION WILL TAPER OFF FROM SW TO NE OVERNIGHT AS
THE WAVE EXITS THE AREA. THE TROUGH THAT IS CURRENTLY LOCATED
ALONG THE WA/OR COAST WILL APPROACH FROM THE WEST ON
MONDAY...BRINGING SCATTERED SHOWERS AND THUNDERSTORMS THAT SHOULD
PERSIST INTO THE EVENING. RIGHT NOW IT LOOKS LIKE THIS TROUGH WILL
HAVE SLIGHTLY MORE MOISTURE ASSOCIATED WITH IT...SO THAT ANY
STORMS THAT DEVELOP SHOULD BE WET.
TUESDAY THROUGH SUNDAY...AS THE TROUGH EXITS THE REGION ON TUESDAY
THE UPPER LEVEL FLOW WILL BECOME ZONAL (WESTERLY). GUSTY WESTERLY
WINDS ARE EXPECTED TO MIX TO THE SURFACE DURING THE AFTERNOON AND
EVENING HOURS UNDER THIS FLOW PATTERN. TEMPERATURES ARE EXPECTED
TO BE AROUND SEASON NORMALS. THE ZONAL FLOW WILL PERSIST THROUGH
THURSDAY THEN A TROUGH WILL DIG ALONG THE PACIFIC NORTHWEST COAST.
THIS TROUGH WILL CAUSE THE UPPER LEVEL FLOW TO TRANSITION TO
SOUTHWESTERLY. THIS FLOW PATTERN IS EXPECTED TO LINGER THROUGH THE
WEEKEND WITH TEMPERATURES WARMING 5 TO 10 DEGREES ABOVE NORM. THE
MONSOONAL MOISTURE WILL BE ALLOWED TO CREEP FARTHER TO THE NORTH
UNDER THIS FLOW REGIME...SO A FEW SHOWERS AND THUNDERSTORMS COULD
DEVELOP ACROSS SOUTHWEST MONTANA AND CENTRAL IDAHO DURING THIS
TIME PERIOD.
&&
.AVIATION...WILDFIRE SMOKE WILL AGAIN REDUCE VISIBILITY DOWN TO 2
MILES IN AREAS THIS AFTERNOON ACROSS. MOUNTAINS WILL BE OBSCURED
NEAR SMOKE PLUMES. VISIBILITY SHOULD IMPROVE LATE TONIGHT AS THE
