Area Forecast Discussion
National Weather Service Duluth MN
403 AM CDT Fri Apr 20 2018

.SHORT TERM...(Today through Saturday)
Issued at 403 AM CDT Fri Apr 20 2018

Quiet weather expected with warmer temperatures during the short
term.

Omega blocking pattern overhead will continue the quiet weather
pattern with warming temperatures today and Saturday. Surface high
pressure will leisurely drift eastward across the region with
light southerly winds. Snow will continue to disappear today as
highs climb into the low to upper 50s. Patchy fog will be possible
tonight, especially in low-lying areas, due to the ripening and
melting snow pack. Lows tonight will dip into the middle to upper
20s. Fog and low stratus will dissipate early Saturday with mostly
sunny skies once again and high sin the low 50s to near 60
degrees.

.LONG TERM...(Saturday night through Thursday)
Issued at 403 AM CDT Fri Apr 20 2018

Dry and mild weather through the weekend then a chance for
precipitation on Tuesday as a cold front moves through the region.
After a brief cool-down behind the cold front temperatures warm
right back up to above normal temperatures late in the week.

A broad area of high pressure over the Midwest and Great Lakes
region will result in fairly quiet weather over the weekend with
southerly flow at low levels advecting in warmer temperatures at
low levels, and the strong April sun helping to raise the
temperature into the 50s and even low to mid 60s in some
locations. On Sunday night into Monday a broad warm frontal zone
tracks across the Northland bringing partly cloudy skies and a
very low chance for light precipitation. A cold front moves
through on Tuesday leading to a widespread chance for
precipitation, with up to a quarter inch or more of rain possible.
Rain may mix with snow in some locations, but this will primarily
be a rain event for most locations. Late in the week northwest
flow through the column may lead to additional chances for
precipitation and increased cloud cover but otherwise the mild
temperatures will continue to prevail with highs in the 50s to low
60s.

These warmer temperatures and possibility for rain on top of the
warmer temperatures could lead to rises on area creeks and
streams.
