...INCREASED FLOOD POTENTIAL BEGINNING LATER THIS WEEK...

SEVERAL FACTORS WILL COMBINE TO CREATE AN INCREASED FLOOD RISK
STARTING LATER THIS WEEK. WIDESPREAD SNOW AND ICE CONTAIN A LARGE
QUANTITY OF STORED WATER...GENERALLY 1.5 TO 3.5 INCHES ACROSS THE
REGION. ACCUMULATING SNOW IS EXPECTED ACROSS THE AREA MONDAY AFTERNOON
INTO MONDAY NIGHT...WITH UP TO ONE HALF OF AN INCH OF WATER
EQUIVALENT POSSIBLE WITH THIS NEW SNOWFALL.

WARMER TEMPERATURES ARE EXPECTED BY TUESDAY AND WEDNESDAY WITH
AFTERNOON HIGHS RISING ABOVE THE FREEZING MARK. NIGHTTIME
TEMPERATURES ARE EXPECTED TO DROP BELOW FREEZING DURING THIS
PERIOD HOWEVER...WHICH SHOULD LIMIT THE AMOUNT OF SNOWMELT AND
RUNOFF THROUGH WEDNESDAY.

MUCH WARMER CONDITIONS ARE ANTICIPATED BY THURSDAY WHICH WILL ACT
TO INCREASE THE RATE OF SNOWMELT. SOME SIGNIFICANT RAINFALL IS
ALSO POSSIBLE THURSDAY AS A STRONGER UPPER LEVEL DISTURBANCE
APPROACHES THE REGION. THIS POTENTIAL RAINFALL COMBINED WITH
INCREASED RUNOFF FROM MELTING SNOW ATOP THE FROZEN GROUND MAY LEAD
TO A HEIGHTENED POTENTIAL FOR FLOODING IN LOW LYING
AREAS...BASEMENTS AND SMALL STREAMS AND CREEKS. SIGNIFICANT RISES
ALONG MAJOR STEM RIVERS COULD FOLLOW.

THESE WARMER CONDITIONS AND RUNOFF LATER IN THE WEEK WILL LEAD TO
SOME POTENTIAL FOR BREAK UP AND DOWNSTREAM MOVEMENT OF THICK ICE
ON RIVERS THAT WOULD INCREASE THE RISK FOR ICE JAMS TO DEVELOP AND
INCREASE THE FLOODING POTENTIAL.

FUTURE FLOODING IS A POSSIBILITY AT THIS TIME...NOT A CERTAINTY.
THE SEVERITY AND TIMING OF FLOODING WILL DEPEND ON THE AMOUNT OF
RAINFALL LATER THIS WEEK AND THE DURATION OF WARMER
CONDITIONS...WHICH REMAINS UNCERTAIN. IF YOU LIVE IN A FLOOD PRONE
AREA...NOW IS THE TIME TO PREPARE FOR POSSIBLE FLOODING. STAY
ALERT TO THE LATEST FORECASTS TRENDS OVER THE NEXT SEVERAL DAYS BY
VISITING WEATHER.GOV/IWX.
