AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
251 PM MDT SUN MAY 24 2009

.DISCUSSION...A MOIST SUBTROPICAL SYSTEM CONTINUES TO CREATE
CONVECTIVE RAIN SHOWERS ACROSS MUCH OF THE NORTHERN ROCKIES THIS
AFTERNOON. THE DEEPEST MOISTURE AND MOST PERSISTENT RAINFALL
THROUGH TODAY HAS BEEN IN THE ANACONDA AREA...BUT IS MOVING EAST
OF THE DIVIDE. HOWEVER...ISOLATED TO SCATTERED SHOWERS...WITH A
POSSIBLE LIGHTNING STRIKE OR TWO...WILL DEVELOP AND PERSIST THROUGH
THE EVENING OVER THE REGION. HIGH PRESSURE WILL BEGIN TO BUILD
MONDAY...BUT WITH SURFACE HEATING AND RESIDUAL LOW LEVEL
MOISTURE...BUILDING CUMULUS AND ISOLATED SHOWERS ARE EXPECTED TO
DEVELOP AGAIN IN THE AFTERNOON...PARTICULARLY NEAR THE CONTINENTAL
DIVIDE.

TUESDAY THROUGH THE WEEKEND...HIGH PRESSURE WILL BE THE DOMINANT
FEATURE DURING THE WEEK AND PROVIDE PLEASANT WEATHER AREA-WIDE
THROUGH AT LEAST THURSDAY. TEMPERATURES WILL HOLD STEADY IN THE
80S AS THE UPPER LEVEL RIDGE CRESTS OVER THE WESTERN U.S.
MIDWEEK. FORECAST MODELS START TO DIVERGE TOWARDS THE END OF THE
WEEK...WITH ONE MODEL WANTING TO HOLD ON TO HIGH PRESSURE WHILE
ANOTHER BEGINS TO BREAK DOWN THE RIDGE WITH AN ADVANCING TROUGH OF
LOW PRESSURE. CONFIDENCE IS NOT QUITE HIGH ENOUGH TO MAKE ANY
CALLS ON EITHER SCENARIO...SO A MENTIONING OF SLIGHT CHANCE OF
SHOWERS AND COOLING TEMPERATURES HAS BEEN CONTINUED IN THE
FORECAST FOR THE WEEKEND.

&&

.AVIATION...CONVECTIVE RAIN SHOWERS WILL SPREAD FROM NORTHWEST
MONTANA THROUGH WEST CENTRAL MONTANA AND CENTRAL IDAHO THROUGH THIS
EVENING UNDER AN UNSTABLE ATMOSPHERE. CEILINGS WILL BE SCATTERED
TO BROKEN WITH SOME BUILDING CUMULUS DURING THIS TIME. ISOLATED
SHOWERS SEEN THIS EVENING SHOULD DISSIPATE TONIGHT.
OTHERWISE...VFR WILL REMAIN THE PREVALENT FLIGHT CATEGORY FOR THE
NEXT 24 HOURS.

&&

.HYDROLOGY...RIVERS WILL CONTINUE TO RUN HIGH THROUGH THE COMING
WEEK MAINLY DUE TO SNOWMELT. RAIN RECEIVED LAST NIGHT IN THE
BITTERROOT AND SOUTHWEST MONTANA COULD HELP PUSH THE STREAMS
TOWARD BANKFULL A LITTLE QUICKER TONIGHT AND MONDAY...BUT THE
PRIMARY CAUSE FOR HIGH WATER WILL CONTINUE TO BE MELTING SNOW.

.MSO WATCHES/WARNINGS/ADVISORIES...
MT...NONE.
ID...NONE.
