Area Forecast Discussion
National Weather Service La Crosse WI
1121 AM CST Thu Feb 16 2017

.SHORT TERM...(Today through Friday)
Issued at 321 AM CST Thu Feb 16 2017

Warm-up starts today. Currently, a warm front extended through the
Dakotas into western IA with scattered to broken warm air advection
mid/high clouds moving southeastward across the forecast area.
Otherwise...temperatures early this morning were in the middle 20s
to near 30.

Middle/upper level ridge of high pressure builds east over the
Central CONUS today into Friday. Increasing compressional heating
under this ridge, along with surface warm air advection and ample
sunshine, will boost high temperatures well into the 30s/40s today
and upper 40s to near 60 on Friday.

.LONG TERM...(Saturday through Wednesday)
Issued at 321 AM CST Thu Feb 16 2017

Unseasonably warm temperatures are on tap through the weekend into
Monday with highs some 20-30 degrees above normal. Saturday looks to
be the coolest of the days with a weak cold frontal passage while
Monday looks to be the warmest in advance of a stronger cold front
marching east out the the Northern Plains.

Rain will become likely by Monday afternoon as that cold front
pushes into the region. Instability looks rather limited at this
time, so kept out any mention of thunder at this point.

Looks a little cooler for Tuesday into Wednesday with slight rain
chances, but temperatures will remain well above normal.


.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1121 AM CST Thu Feb 16 2017

An area of low pressure will move slowly east across Canada
through Friday morning. This will keep the local region in the
southerly flow with the winds gradually coming around to the
southwest late tonight into Friday morning. Not much in the way of
cloud cover is expected other than some high level clouds, so look
for the VFR conditions to continue through the period.


Issued at 321 AM CST Thu Feb 16 2017
