...Rain Today Into Tonight...Within Bank Rises And Minor Flooding
Possible On Some River Systems...

An unseasonably warm and moist weather system is going to bring a
round of spring-like rain and isolated storms today into tonight.
Rain amounts of 1/2 inch are likely for most locations, with a
few amounts up to 1 inch possible. These rains will be falling on
wet and thawing grounds, with many soils still frozen a few
inches below the surface. These soil conditions are going to be
favorable for more runoff than normal, especially from higher
rainfall rates in any thunderstorm.

Most streams and rivers are already running higher than normal
from above normal precipitation since last summer and the recent
snowmelt. The expected rainfall is likely to create ponding of
water in low laying areas along additional within bank rises on
many streams and rivers. Minor flooding will also be possible in a
few locations through the middle of the week.

Those living near streams and rivers should remain alert for
rising water levels later today into Tuesday. If you observe
significant rises or any flooding, notify local law enforcement
to relay your report to the National Weather Service.
