..aviation update...

issued at 305 PM CST Wed Nov 22 2017

Weak clipper system was located in the northern plains with a warm
front located in the central Dakotas. Some light snow was falling in
northern Minnesota with warm air advection mid/high clouds spreading
southeast into Iowa and northern Illinois. Radar was showing mid level
returns in southeast Minnesota into northern Iowa. However, because of the
very dry low levels of the atmosphere I haven't seen any
precipitation reaching the ground.

Mid afternoon temperatures across the dvn cwa were in the 30s.
Elsewhere, downsloping Chinook winds off The Rockies was warming
temperatures into the 60s to lower 70s from SW ND southward to the
Texas Panhandle.


Short term...(this evening through Thanksgiving day)
issued at 305 PM CST Wed Nov 22 2017

Quiet with moderating temperatures.

Tonight: considerable mid/high level clouds will be noted with warm
air advection taking place. Any isolated flurries or sprinkles that
somehow manage to make it to the ground will end this evening.
Otherwise, due to the clouds and south winds temperatures will not
be as cold as early this morning. Lows will be in the 20s.

Thanksgiving day: a weak surface trough (more of a wind shift to the
northwest) will move across the cwa during the day as weak clipper
tracks into the Great Lakes region. Skies will clear early in the
morning with much of the day being sunny. Temperatures should
moderate into the 40s to lower 50s with rather light west to
northwest winds. This will make for a nice day overall.

Long term...(thursday night through wednesday)
issued at 305 PM CST Wed Nov 22 2017

Forecast focus on a quiet weather pattern for the remainder of this
month and at least into the first week of December. No significant
precipitation is expected. The storm track will be across Minnesota and WI
or southern Canada with a roller-coaster ride of temperatures
expected. The warmest days will be Friday and Monday with highs well
into the 50s to lower 60s. We will be close to record highs on
Friday and it is possible the maximum temperatures currently in
the grids may be too cool. See climate section below.


Aviation...(for the 00z tafs through 00z Thursday evening)
issued at 511 PM CST Wed Nov 22 2017

A weak storm system passing well north of the terminals will
provide little other than a wind shift and period of high clouds
tonight. Conditions will remain VFR tonight through Thursday.
