HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE GRAND FORKS ND
346 AM CDT MON JUN 3 2013

...SHOWERS AND THUNDERSTORMS MAY AGAIN CAUSE SOME FLOODING ISSUES...

AS THE FIRST MONTH OF THE SUMMER SEASON GETS UNDERWAY...THE
WEATHER PATTERN CONTINUES TO PROVIDE THE LIKELIHOOD FOR ABOVE
NORMAL RAINFALL.

A SLOW MOVING...STRONG EARLY JUNE STORM OVER MONTANA WILL MOVE
INTO WESTERN NORTH DAKOTA TONIGHT. AN INCREASING SOUTH FLOW AT THE
SURFACE WILL CAUSE LOW LEVEL MOISTURE TO RETURN TO THE RED RIVER
AND LAKES REGION. THIS SETS THE STAGE FOR MORE SHOWERS AND
THUNDERSTORMS. THE STORM SYSTEM WILL DRIFT SLOWLY EAST REACHING THE TRI-
STATES JUNCTURE BY TUESDAY EVENING. IT SHOULD EXIT THE AREA ON
WEDNESDAY.

THE BEST CHANCES OF SIGNIFICANT RAINFALL...WITH AMOUNTS OF 1.5 TO
2 INCHES...LOOKS TO BE ALONG AND SOUTH OF THE U.S. HIGHWAY 200
CORRIDOR. AS IS ALWAYS THE CASE WITH THUNDERSTORMS LOCALLY HIGHER
AMOUNTS ARE PROBABLE. AT THIS TIME THE HIGHEST AMOUNTS ARE FORECAST
FROM THE VALLEY CITY TO FARGO AND FERGUS FALLS AREAS.

IT APPEARS THAT NORTHEAST NORTH DAKOTA WILL BE ON THE NORTHERN
EDGE OF THE HEAVIEST RAINFALL. AMOUNTS OF LESS THAN AN INCH SHOULD
NOT CAUSE ADDITIONAL FLOODING PROBLEMS. THERE IS FAIRLY HIGH
CONFIDENCE WITH THE EXPECTED TRACK OF THIS SYSTEM...ALTHOUGH ANY
CHANGE IN THE TRACK WILL SHIFT THE HEAVIER RAINFALL AMOUNTS.

LOOK FOR ADDITIONAL STATEMENTS AND FORECASTS ON THIS DEVELOPING
HYDROLOGICAL SITUATION.
