Area Forecast Discussion
National Weather Service La Crosse WI
310 AM CDT Fri Oct 27 2017

.SHORT TERM...(Today through Saturday night)
Issued at 310 AM CDT Fri Oct 27 2017

Water vapor satellite this morning shows an upper level low over
east central Minnesota with the trough axis to the southwest. At
the surface, the main surface low was over far northern Wisconsin.
Regional radars show the main area of precipitation was over
northeast Minnesota into the U.P. of Michigan with some light
precipitation in the deformation zone dropping southeast through
eastern Minnesota.

The precipitation chances across the area into tonight will come
from the deformation zone as it moves slowly east/southeast across
the area. The upper level low will move slowly east across
northern Wisconsin into the eastern section of the U.P. through
tonight. The main short wave trough is swinging across the area
now and will be moving off to the east so there will not be much
upper air support for the precipitation in the deformation zone.
The 27.00Z models do show some weak QG convergence in the 1000-700
mb layer to come across the area today with this dissipating this
evening. A band of weak frontogenesis in the 1000-850 mb layer
should move steadily east across the area with the deformation
zone along with about 2 ubar/s of up glide on the 280K isentropic
surface. Looking at forecast soundings, the bulk of the lift will
initially be in the low levels below the dendritic growth zone and
then by late afternoon it should get into the DGZ. Despite this
weak lift, the soundings do look to be cold enough and with ice in
the cloud to support snow, so the precipitation type will be
controlled by boundary layer temperatures. Across the western
sections, temperatures look to be just cold enough to support
light snow this morning before a little bit of warming this
afternoon for primarily a rain/snow mix. This mix should then
change back to light snow this evening before ending. Some light
accumulations will likely occur this morning and again in the
evening with some spots possibly having totals up to 1.5 inches.
Given the general weak forcing, not expecting the rates to be high
enough to overcome the warm road temperatures and the
accumulations should be limited to grassy surfaces. Farther east,
accumulations look to very minimal as temperatures will remain
warm enough for rain through much of the evening before mixing
with and then changing over to light snow.

As colder air continues to filter in on the backside of this
system, temperatures tonight look to drop into the upper 20s
across much of the area west of the Mississippi River. Since the
growing season is still technically going, will have to issue a
freeze warning.

.LONG TERM...(Sunday through Thursday)
Issued at 310 AM CDT Fri Oct 27 2017

The next system will drop out of Canada starting Sunday as an
upper level low moves into the northern Great Lakes. This low then
should move into southeast Canada early next week. The first round
of precipitation looks to start spreading in Sunday afternoon in
the warm air advection ahead of the system. Some differences
between the models on just how much ice will be in the clouds
across the far northern sections of the forecast area as this
first round looks to be ending Sunday evening. The 27.12Z NAM
would suggest the ice would remain in the clouds while the GFS
drops it out during the evening but the timing looks to be after
the precipitation has ended. For now, will go with the idea of
ice in the clouds and let the boundary layer temperatures control
the precipitation type of rain or snow. The precipitation will
then come back in for Monday and Monday night in the deformation
zone on the back side of the surface low. Another system should
come out of central Canada for the middle of next week, but some
differences between the GFS and ECMWF on the path. The GFS keeps
the system along and north of the Canadian border while the ECMWF
drops it across the Upper Midwest and also then has more
precipitation for the area. For now, will just carry some general
20 to 40 percent chances.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1140 PM CDT Thu Oct 26 2017

A strong cold front moved across TAF airfields this evening,
ushering in MVFR ceilings and gusty west-northwest winds. These
conditions will continue through the overnight hours at both
KRST/KLSE.

Wrap-around precipitation will then move slowly from west to east
through the day on Friday as a strong low pressure system moves
across the region. Temperatures will be cold enough at KRST to
result in a rain/snow mix beginning around 27.14Z and continuing
through much of the afternoon. Expect reductions in visibility in
the 2-3SM range, although lower values are possible if
precipitation changes to all snow. Any wintry mix that lingers
into the evening at KRST is likely to change over to all snow.
Precipitation will be delayed at KLSE until later in the afternoon
and with warmer temperatures, expect mostly rain through the
period. Some reductions in visibility into the MVFR range are
possible late in the period. Ceilings at KRST are likely to
eventually drop below 1000 ft agl Friday morning, but should
remain solidly within the MVFR range at KLSE.

At KRST, strong northwest winds will persist through the period,
gusting frequently between 25 and 30 kts. At KLSE, northwest winds
are not expected to be as strong and may favor a more west-
southwesterly direction for much of Friday before turning back to
the northwest in the evening.
