Area Forecast Discussion
National Weather Service Duluth MN
639 PM CDT MON JUL 25 2016

.SHORT TERM...(This evening through Tuesday)
Issued at 313 PM CDT Mon Jul 25 2016

A fairly quiet afternoon across the forecast area with the
surface ridge now settling over western Iowa, with the ridge axis
extending well up across Minnesota. A very weak trough axis
extends from a surface low over far northern Manitoba, south
through Manitoba to the Dakotas to Wyoming. As of this afternoon
there are not even clouds along the front south of Lake Winnipeg,
but there are some storms and cloud cover farther north. This
front is expected to sag southeast across the Northland tonight
and Tuesday. It should bring some precipitation chances to the
area late tonight, as not only does the front move in, but we get
a weak shortwave that ripples through our upper level flow.
Another ripples through during the day on Tuesday, and combined
with diurnal effects expect stronger storms and more widespread
coverage Tuesday afternoon. Have lowered tonight`s min temps as we
are not changing airmass very much and min temps were in the lower
50s in parts of the Arrowhead this morning. Even with the extra
cloud cover with the front we should manage to radiate into the
middle and upper 50s tonight in parts of the Arrowhead and NW
Wisconsin.

.LONG TERM...(Tuesday night through Monday)
Issued at 313 PM CDT Mon Jul 25 2016

A stubborn stationary front will result in a chance for showers and
perhaps a few thunderstorms along and south of the Highway 2
corridor Tuesday night into Wednesday...with a slight chance for
showers and storms continuing through the rest of the work week
along the southern periphery of the CWA. High pressure will build in
from the north resulting in cooler temperatures, perhaps a day or
two actually below normal ending a 10+ day run of above normal
temps. Warming trend late in the weekend into early next week as the
high pressure moves off to the east and south/southwest flow results
in a warm airmass being advected up the Great Plains into the upper
Midwest.

No severe weather expected through the long term. While showers and
few storms are possible mid-week along the front, instability will
be fairly limited - generally less than 500 j/kg MUCAPE. Thus, no
organized convection expected.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 635 PM CDT Mon Jul 25 2016

VFR Conditions will prevail through the period. However a weak
cold front will drop out of canada into northern minnesota
Overnight. The boundary will be the focus for Scattered showers
and isolated thunder late tonight through Tuesday. Due to
uncertainties in timing and coverage, have continued to carry
broadbrush VCSH to cover the convection potential.
