system snow had ended last night with cloudy skies prevailing
over much of the area with generally north to northeast winds at
the surface. the chilly northeast flow behind the departing
upper level trof will keep temperatures well below normal for
today with highs almost exclusively limited to the 30s. an
impulse moving rapidly east in the upper flow is expected to
track south of the forecast area tonight. have kept snow out of
the south areas for now including areas south of a line from
marion to portland; however, can not rule out a brief period of
light snow.
a very active pattern of wet and mild weather is ahead this upcoming
week. ensemble scenarios (desi) graphics show accumulated precipitation
around 2.5" (inches) by sunday. at this time given the antecedently
dry conditions across the forecast area, any areal flooding or rises
on rivers leading to flooding will not be immediate; however, periods
of light to moderate rain over a long period of time will eventually
saturate soils and cause runoff which may eventually lead to hydrologic
issues late this week. along with the anomalously wet pattern ahead,
mild weather will also prevail. temperatures are expected to average
close to 15 to 25 degrees above normal late this week. gfs 500 mb
forecast height anomalies are 200 meters above normal for this time
of year. temperatures are expected to remain above freezing, so icy
roads are not expected.
