UPDATED AVIATION

.UPDATE...AN UPPER LEVEL TROUGH REMAINS OVER THE PACIFIC NORTHWEST
CAUSING MOISTURE TO STREAM ACROSS MONTANA AHEAD OF THE SYSTEM.
WIDESPREAD RAIN SHOWERS FOR MY ENTIRE FORECAST AREA CONTINUE TO
LOOK FAVORABLE AT THIS TIME SO HAVE NOT MADE SIGNIFICANT CHANGES
TO OVERNIGHT POPS. HOWEVER...AN UNSTABLE AIRMASS THAT BROUGHT A
SEVERE THUNDERSTORM TO THE LEWISTOWN AREA DURING THE AFTERNOON HAS
RETREATED INTO EASTERN MONTANA SO HAVE REMOVED THE MENTION OF
THUNDER FROM ALL BUT THE FAR EASTERN PORTIONS OF BLAINE AND FERGUS
COUNTY FOR THE REMAINDER OF THE EVENING. ALSO TWEAKED WINDS TO BE
MORE IN LINE WITH OBSERVATIONS AND LATEST MODEL RUNS. FINALLY...HAVE
TWEAKED OVERNIGHT LOW TEMPERATURE DOWN IN THE LEWISTOWN AREA...BUT
HAVE LEFT TEMPERATURES ALONE FOR THE REMAINDER OF THE CWA.
REMAINDER OF THE FORECAST UPDATES WERE TRIGGERED BY THE ISSUANCE
OF QUITE A FEW RIVER HIGHLIGHTS TONIGHT...PLEASE REFER TO THE

WITH WIND GUSTS UP TO 25KTS TOMORROW AFTERNOON OVER THE NORTHERN
PLAINS. PRECIPITATION WILL DECREASE FROM SOUTH TO NORTH BY TOMORROW
AFTERNOON. MLS

&&

.HYDROLOGY...
MANY RIVERS ACROSS THE REGION CONTINUE TO RUN HIGH FROM A
COMBINATION OF SNOW MELT AND RAINFALL RUNOFF. SEVERAL DAMS ARE
ALSO RELEASING WATER IN RESPONSE TO INFLOW TO THE RESERVOIRS.
A PACIFIC WEATHER SYSTEM WILL BRING WET WEATHER TO THE AREA THROUGH
THURSDAY AND ADDITIONAL RAINFALL RUNOFF WILL MOVE THROUGH THE
DRAINAGES. FLOOD ADVISORIES REMAIN IN EFFECT FOR JUDITH BASIN AND
FERGUS COUNTIES. HAVE ALSO ISSUED A FLOOD ADVISORY FOR
CASCADE...AND LEWIS AND CLARK COUNTIES DUE TO BANKFULL LEVELS ON
THE MISSOURI RIVER UPSTREAM FROM CASCADE AND CRAIG...AND FOR
PRICKLY PEAR CREEK NEAR EAST HELENA WHICH IS REPORTED TO BE NEAR
BANKFULL. WATER LEVELS ON THE BIG HOLE RIVER NEAR MELROSE AND THE
GALLATIN RIVER NEAR LOGAN ARE RISING RAPIDLY. AN EVENING FORECAST
FROM THE MISSOURI RIVER FORECAST CENTER PLACES BOTH OF THESE
RIVERS ABOVE FLOOD STAGE JUST AFTER MIDNIGHT TONIGHT. AS A RESULT
I HAVE ISSUED FLOOD WARNINGS THROUGH SATURDAY MORNING FOR THESE
RIVERS. FINALLY...A FLOOD WATCH IS IN EFFECT FOR BEAVERHEAD...
MADISON AND GALLATIN COUNTIES THROUGH FRIDAY AFTERNOON SINCE MANY
OTHER SMALL STREAMS...CREEKS AND RIVERS ARE EXPECTED TO APPROACH

BE OVER OVER EASTERN WA/OR/NEVADA THIS EVENING AND MOVE ACROSS

FOCUSED OVER THE NORTHERN PLAINS THURSDAY. AS THE SYSTEM GRADUALLY
MOVES EAST...UPSLOPE FLOW AT LOW LEVELS WILL KEEP MOISTURE FOCUSED
OVER THE NORTHWEST ZONES...THE AIRMASS WILL BE DRIER NEAR HAVRE

UP RESIDENCE OVER THE WEST COAST ON SATURDAY SETTING UP
SOUTHWESTERLY FLOW ALOFT OVER THE AREA AND THE POSSIBILITY OF
AFTERNOON AND EVENING CONVECTION. THE UPPER TROF MOVES VERY LITTLE
ON SUNDAY AND MONDAY BUT EJECTS SHORT WAVE ENERGY ACROSS THE AREA
ALLOWING FOR CONVECTIVE ACTIVITY TO INCREASE IN AREAL COVERAGE BOTH
DAYS. THE UPPER TROF THEN LIFTS OUT OVER THE AREA ON TUESDAY
ALLOWING FOR CONVECTIVE ACTIVITY TO BECOME ISOLATED. THE MODELS
BECOME QUITE DIVERGENT BY WEDNESDAY WITH THE EUROPEAN BUILDING A
WEAK RIDGE OVER WESTERN MONTANA WHILE THE GFS DEVELOPS YET ANOTHER
