HYDROLOGIC OUTLOOK

300 AM MDT MON MAY 23 2016   

...SPRING RAINS AND MELTING MOUNTAIN SNOWPACK WILL CONTINUE THIS
WEEK AND THROUGH THE UPCOMING MEMORIAL DAY WEEKEND...

AN UNSETTLED SPRING WEATHER PATTERN WILL CONTINUE TO RESIDE OVER THE
REGION FOR THE NEXT SEVERAL DAYS.

ESTIMATED RAINFALL AMOUNTS TODAY THROUGH WEDNESDAY WILL GENERALLY BE
ON THE LIGHT SIDE...RANGING FROM ABOUT 0.10 TO 0.50 FOR ALL AREAS
EXCEPT GLACIER PARK. IN GLACIER PARK...THE PRECIPITATION WILL BE A
BIT HEAVIER...POSSIBLY UP TO AN ADDITIONAL INCH OF RAINFALL.

FROM THURSDAY THROUGH MEMORIAL DAY...ESTIMATED PRECIPITATION AMOUNTS
WILL BE SLIGHTLY HEAVIER AND A BIT MORE WIDESPREAD. OVERALL
PRECIPITATION AMOUNTS OF 0.40 TO 0.80 INCHES WILL BE POSSIBLE IN
MANY AREAS...WITH ISOLATED LOCATIONS RECEIVING MORE THAN 1 INCH OF
RAINFALL.

AFTERNOON TEMPERATURES OVER THE NEXT WEEK OR SO...ARE GENERALLY
GOING TO AVERAGE BELOW NORMAL TO NEAR NORMAL IN MOST AREAS. THUS
MOUNTAIN SNOWMELT IS NOT EXPECTED TO BE ACCELERATED DUE TO WARM
TEMPERATURES.

SOME RIVERS AND CREEKS THAT HAVE SEEN RISES RECENTLY BECAUSE OF
RAINFALL AND SNOW MELT INCLUDE THE JEFFERSON RIVER...BIG HOLE RIVER
AND GALLATIN RIVER...ALONG WITH CLEAR CREEK...TENMILE CREEK AND
BELT CREEK.

AT THIS TIME...GIVEN THE CURRENT MOUNTAIN SNOWPACK...THE FORECASTED
HIGH TEMPERATURES AND THE FORECASTED RAINFALL...THE POTENTIAL FOR
WIDESPREAD FLOODING ON THE BIGGER STREAMS AND RIVERS ACROSS THE
REGION IS LOW.

HOWEVER...SHOULD SOME AREAS RECEIVE A BIT HEAVIER RAINFALL LATER
THIS WEEK THAN CURRENTLY FORECASTED...SOME MINOR PROBLEMS COULD
DEVELOP ON THE RIVERS OR CREEKS MENTIONED ABOVE...AND THOSE
ADDITIONAL SMALL STREAMS THAT FLOW OUT OF THE
MOUNTAINS...PARTICULARLY IN AREAS THAT RECEIVE MORE THAN ONE INCH OF
RAINFALL. THE MAIN IMPACT WOULD BE WATERWAYS EXCEEDING
BANKFULL...AND POSSIBLY CAUSING MINOR FLOODING IN LOW LYING AREAS OR
AGRICULTURAL LAND NEXT TO THE WATERWAY.

FOR THOSE PLANNING RECREATION ON AREA WATERWAYS LATER THIS WEEK AND
THROUGH THE UPCOMING HOLIDAY WEEKEND...BE PREPARED FOR CHANGING
CONDITIONS AND HIGHER STREAM FLOWS.

LISTEN TO NOAA WEATHER RADIO OR YOUR LOCAL MEDIA FOR THE LATEST
UPDATES.
