HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE GREAT FALLS MT
230 PM MDT SUN APR 20 2014

...WARMER TEMPERATURES EARLY THIS WEEK TO BE FOLLOWED BY THE
POTENTIAL FOR WIDESPREAD PRECIPITATION AND RAIN ON SNOWPACK BY MID
WEEK...

WARMER TEMPERATURES ARE EXPECTED EARLY THIS WEEK BEFORE A PERIOD OF
COOLER AND WETTER CONDITIONS BY THE MIDDLE TO LATER PART OF THE
WEEK. AFTERNOON TEMPERATURES THROUGH TUESDAY WILL CLIMB INTO THE 60S
AT LOWER ELEVATIONS AND INTO THE 40S AND 50S IN THE MOUNTAINS.
OVERNIGHT LOWS AT MID-ELEVATIONS WILL REMAIN ABOVE FREEZING EACH
NIGHT. THIS WILL CAUSE AN INCREASE IN MOUNTAIN SNOWMELT WITH RISING
WATER LEVELS ANTICIPATED ON CREEKS...SMALL STREAMS AND RIVERS.

A PERIOD OF WETTER CONDITIONS IS EXPECTED BY MID TO LATE WEEK. AT
THE ONSET OF PRECIPITATION ON TUESDAY AFTERNOON...SNOW LEVELS
BETWEEN 7500 AND 8500 FEET INDICATE THAT RAIN MAY FALL ON TOP OF
MOUNTAIN SNOWPACK AND INCREASE THE RATE OF SNOWMELT. WITH COOLER AIR
MOVING IN WEDNESDAY...PRECIPITATION WILL CHANGE TO ALL SNOW AND
REMAIN SNOW THROUGH THE END OF THE WEEK.

THE SITUATION WILL CONTINUE TO BE MONITORED BY THE NATIONAL WEATHER
SERVICE. RESIDENTS ALONG RIVERS...STREAMS...AND CREEKS SHOULD
PREPARE FOR RISING WATER LEVELS...AND BE PREPARED TO TAKE ACTION IF
WATERWAYS EXCEED BANKFULL.
