HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE EASTERN NORTH DAKOTA/GRAND FORKS ND
130 PM CDT THU MAR 19 2015

...SPRING THAW UPDATE FOR RED RIVER OF THE NORTH...

...MILD SPRING WEATHER KEEPS LOW FLOOD THREAT UNCHANGED...

. SPRING FLOOD UPDATE...OUR SPRING THAW WEATHER AND HYDROLOGIC
   CONDITIONS HAVE REMAINED ON TRACK WITH WHAT WAS EXPECTED SINCE
    THE LAST OUTLOOK ISSUED BACK ON THURSDAY, MARCH 5TH. THE RISK
     FOR SIGNIFICANT SPRING SEASON FLOODING REMAINS WELL BELOW
      HISTORICAL NORMALS...AND WOULD NOW BE LARGELY DEPENDENT
       ON SPRING OR SUMMER RAINS...AS THE WINTER PERIOD SNOWPACK
        HAS DISSIPATED.

. GENERAL CONDITIONS...

 - SNOWPACK...THERE IS LITTLE TO NO REMAINING SNOWPACK EXCEPT FOR
    FRAGMENTS OF SNOW PILES OR DRIFTS. PERIODS OF LIGHT SNOW ARE
     STILL POSSIBLE THROUGHOUT THE SPRING.

 - GROUND FROST...TOPSOIL HAS BEEN THAWING DOWN TO HALF A FOOT
    OR A FOOT DEEP OR MORE ACROSS MOST OF THE BASIN. DEEPER LAYER
     SOILS REMAIN FROZEN TO DEPTHS OF 4 FEET OR MORE IN PLACES
      AND SUCH DEEP FROST WILL SLOWLY COME OUT. PERSISTENT
      TEMPERATURES ABOVE THE FREEZING POINT THROUGHOUT THE LATTER
       HALF OF MARCH AND/OR PERIODS OF LIGHT SPRING RAINS WILL
        AID THAT PROCESS.

 - RIVER/LAKE CONDITIONS...ICE COVER ON THE RIVERS...STREAMS AND
    LAKES IN THE RED RIVER BASIN HAS RESPONDED TO SOLAR AND
     THERMAL DEGRADATION THROUGH EARLY MARCH. MOST SMALLER
      TRIBUTARY STREAMS ARE MAINLY ICE FREE AND FLOWING. THE
       MAINSTEM RED RIVER IS OPEN AND FLOWING FREELY IN MUCH OF
        THE SOUTHERN BASIN BUT REMAINS ICE COVERED FROM GRAND
         FORKS NORTHWARD. REMAINING ICE ON THE RED RIVER AND ON
          AREA LAKES WILL CONTINUE TO ERODE THROUGH LATE MARCH.

 - UPCOMING WEATHER...WEATHER CONDITIONS THROUGH THE WEEKEND AND
    COMING WORK WEEK ARE UNSETTLED...WITH TEMPERATURES EXPECTED TO
     RANGE NEAR SEASONAL NORMALS. PERIODS OF LIGHT RAIN OR SNOW
      ARE EXPECTED LATE THIS WEEK AND AGAIN EARLY NEXT WEEK...
       WITH TOTAL PRECIPITATION AMOUNTS OF FROM ONE QUARTER TO
        ONE HALF INCH OF LIQUID EQUIVALENT POSSIBLE.

 - SPRING CLIMATE OUTLOOK...THE CLIMATE OUTLOOK FOR THE MONTH OF
    APRIL AND FOR THE THREE MONTH APRIL-MAY-JUNE PERIOD LOOK FOR
     TEMPERATURES TO RANGE NEAR OR SLIGHTLY ABOVE NORMAL...AND
      FOR PRECIPITATION TO CONTINUE SLIGHTLY BELOW NORMAL.

 - THROUGHOUT THE SPRING AND SUMMER...RIVER FORECASTS WILL BE
    ISSUED IF AND WHEN ANY FORECAST POINTS ARE EXPECTED TO RISE
     TO OR ABOVE THEIR RESPECTIVE ACTION STAGE.
