Area Forecast Discussion
National Weather Service Duluth MN
645 AM CDT Wed Sep 20 2017

.SHORT TERM...(Today through Thursday)
Issued at 413 AM CDT Wed Sep 20 2017

A strong cold front will continue pushing eastward through the
Northland this morning and this afternoon. Showers and
thunderstorms are forecast along and ahead of the boundary, and
some will be strong or severe. Recent RAP analysis highlights a
general trend toward increasing stability over the area. Clearing
skies are expected as high pressure builds in behind the front
this afternoon through Thursday. Temperatures will trend a bit
cooler this afternoon and tonight in the wake of the cool front.
As the ridge axis slides to the east Thursday, look for winds to
back southerly yielding warmer temperatures by Thursday afternoon.

.LONG TERM...(Thursday night through Tuesday)
Issued at 413 AM CDT Wed Sep 20 2017

Not much change from the past several days. A deep trough of low
pressure will loiter over the western half of the continent for
much of the extended period. A nearly stationary front will be
located somewhere near/over the area and numerous shortwaves will
ride across the eastern branch of trough, and into the Northland.
Several rounds of strong to severe thunderstorms are expected
beginning Thursday night and continuing into next week. While the
details and placement vary from day to day, the Northland will see
a prolonged period of active weather. There is also a potential
for heavy rainfall for any portions of the Northland which remain
near the baroclinic zone.

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 639 AM CDT Wed Sep 20 2017

A frontal boundary was moving into western portions of the
Northland as of 1130Z with showers and a few thunderstorms
occurring ahead of it. Ceilings have lowered for most areas to
MVFR of IFR with some LIFR conditions occurring as well. As the
front moves through the area today, the wind will veer to west to
southwest and become gusty. This will either lift ceilings to VFR
or ceilings will end altogether. The wind will diminish quickly
this evening and skies will be clear to partly cloudy. Fog will
be possible tonight.
