This hazardous weather outlook is for portions of eastern North
Dakota, west central and northwest Minnesota.

.DAY ONE...Today and Tonight

The probability for widespread hazardous weather is low.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

The snowmelt will continue, with daytime highs above freezing each
day. Nighttime lows look to be a little more variable through
Thursday night, then they should fall below freezing again Friday
night and beyond, which would slow the runoff cycle a little.

For Thursday through Saturday, there is a potential for showers,
even isolated thunder, across portions of the region. This could
lead to a quicker snowmelt and runoff in areas where snow
remains.

River flood warnings have been issued for select locations within
the southern Red River Basin. Refer to the latest flood warnings
and statements for detailed information on specific locations.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated.
