Short term...(today through friday)
issued at 223 am CST Thu Nov 23 2017

First off, Happy Thanksgiving everyone! I think most of US will be
thankful for this nice forecast today as high pressure will be our
dominate weather feature. Beside a few high level cirrus clouds from
time to time, net outcome will be mostly sunny skies with highs
topping off in the upper 30s to the middle 40s.

Southerly flow kicks in tonight in response to low pressure tracking
from Saskatchewan into western Ontario. This will keep overnight
lows from falling off too much with temperatures only dropping into
the 30s.

Warmer start on Friday and southwest flow ahead of an approaching
cold front will boost temperatures to near 50s across north central
WI to the middle and upper 50s elsewhere. Will likely see a few
lower 60s across far northeast Iowa/far southwest WI. Cold front
pushes through during the afternoon but look like better moisture
convergence/chance of rain will be north of I-94.

High pressure builds in Friday night for clearing skies with
overnight lows expected to be in the 30 to 35 degree range.

Long term...(friday night through wednesday)
issued at 223 am CST Thu Nov 23 2017

Quiet and relatively mild weather through this weekend into next
week as the main storm track stays farther north over Canada keeping
US dry. Flow off the Pacific/plains into the region will also keep
our temperatures at or above seasonal normals.


Aviation...(for the 18z tafs through 18z Friday afternoon)
issued at 1058 am CST Thu Nov 23 2017

Quiet VFR conditions expected through Friday morning. A short wave
trough moving across southern Canada tonight may bring a few mid
level clouds to the area, but not expecting there to be enough
moisture for these to produce a ceiling. Another short wave
trough will be right behind the one for tonight with an area of
low pressure to be along the North Dakota/Canada border. This will
turn the winds more to the south with an increase to 10 knots or
just above this evening into Friday morning. As the short wave
trough and surface low move east Friday morning, a cold front will
approach from the west with a gradual increase in the cloud cover,
but do not look for any ceilings or precipitation to form until
Friday afternoon.
