Area Forecast Discussion
National Weather Service Duluth MN
310 PM CDT SUN JUL 24 2016

.SHORT TERM...(This evening through Monday)
Issued at 310 PM CDT Sun Jul 24 2016

A low over far northwest Ontario will shift east to James Bay by
Monday morning. It`s associated upper level trough will shift east
from the Northern Plains to the Northland late this afternoon and
this evening. The synoptic lift provided by the trough could
develop scattered showers and isolated storms across far northern
Minnesota late this afternoon through this evening amidst the well
mixed, breezy west-northwest flow. Any storms will likely be
relatively weak.

There will be clearing overnight as surface high pressure shifts
from the Central/Northern Plains into the Upper Midwest. Light
west-northwest flow over the Northland overnight should be just
enough to stave off the threat of fog, and help prevent dramatic
cooling overnight. Overnight lows will be in the upper 50s and
low 60s.

Monday looks mostly sunny with lighter west-northwest flow. Highs
will primarily be in the low 80s.

.LONG TERM...(Monday night through Sunday)
Issued at 310 PM CDT Sun Jul 24 2016

The upper air pattern in the extended period will start out
fairly zonal with a big ridge of high pressure over the southern
tier of the U. S. with a broad trof across much of Canada and into
the Gulf of Alaska. It`s this trofiness that will be the
northland`s weather maker for he next week. Tuesday will be a
change with an increasing dewpoints as the surface high slides
southeast and return flow sets up. A little dip in the atmospheric
flow will result in a vorticity maxima and with the increasing
humidity and temperature advection associated with the return flow
will see chances of storms. The showers and storms should begin
across northern MN where the initial instability and strongest
advection will take place...then this area will slide south during
the afternoon as the surface high moves into northern IL and IN.
the rest of the week will be dominated by the upper trof with
increasing humidity and chances of storms.
