Area Forecast Discussion
National Weather Service La Crosse WI
208 AM CST Fri Nov 16 2018

.SHORT TERM...(Today through Sunday)
Issued at 208 AM CST Fri Nov 16 2018

Local and regional radars showing a couple bands of light snow
moving across the area early this morning. These are in association
with a short wave trough crossing the region and this wave is
expected to be well east of the area by 12Z which will take the snow
bands out of the area as well. Will continue to monitor trends, but
not expecting to have any mention of light snow in the forecast to
start today.

Water vapor satellite was showing the next short wave trough was
over extreme southern British Columbia. With the fast northwest
flow aloft, the wave will rapidly move southeast and across the
region tonight into early Saturday morning. There are still some
differences between the 16.00Z models on the strength of this wave
as it comes across, but the general consensus is that it will
produce a period of weak to moderate pv advection in the 500 to
300 mb layer tonight. This forcing will be aided by some jet
dynamics with the area coming under the right entrance region of
the 300 mb jet. The surface low with this wave does not look to be
all that strong with the models again not having a lot of
agreement on the track. The 16.00Z NAM and 15.21Z SREF would take
the low from northwest Iowa into north central Illinois. The
16.00Z GFS has the low tracking along the Iowa/Missouri border
with the 16.00Z ECMWF even farther south in Missouri. Both the NAM
and GFS bring a band of weak to at times moderate frontogenesis
in the 750 to 550 mb layer right across the area. Despite the
differences in the placement of the surface low, the rest of the
forcing from the models seems to be lining up for a band of snow
to fall across much of the area. Looking at the 15.21Z SREF, there
doesn't look to be much of a signal for the dendritic growth zone
to be all the deep, with the best signal for between 50 and 100
mb with snowfall rates of an inch an hour or less. The SREF plumes
have accumulations for Rochester between 0 and 7 inches with the
mean about 3.5 inches. A similar spread for La Crosse with the
mean right at 3 inches. Will issue a winter weather advisory for
areas generally along and southwest of Interstate 94 for
accumulations in the 2 to 4 inch range.

Other than some lingering light snow over the eastern parts of the
area Saturday morning, the rest of the weekend looks to be dry as
a large area of high pressure comes out of the Dakotas and moves
southeast across the region. Temperatures will cool down some
again with highs generally in the 20s and overnight lows in the
single digits and teens.

.LONG TERM...(Sunday night through Thursday)
Issued at 208 AM CST Fri Nov 16 2018

Another short wave trough will zip across the Upper Midwest late
Sunday night and Monday morning. The upper level ridge axis will
move onshore over the weekend which will push this next wave
farther northeast with its track than the one coming through
tonight. As a result, the surface low should track across
Minnesota into Wisconsin with any light snow falling north of the
low. The ECMWF brings this system through almost dry while the GFS
brushes the northern parts of the area with a little bit of light
snow. After that, the upper level ridge axis looks like it will
continue to move east and by over the central part of the country
by Thanksgiving day. This should allow for a moderation in
temperatures to occur with highs returning to the 40s for
Wednesday and Thanksgiving.

&&

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1058 PM CST Thu Nov 15 2018

MVFR/IFR ceilings will continue into at least Friday morning, with
some light rains/snow impacting KRST/KLSE through around 16.08Z
as an upper level shortwave trough and cold front move through.
Winds may gust up to 25 kts behind the cold front overnight before
diminishing on Friday. A brief return to VFR is possible Friday
afternoon but another system will bring a round of accumulating
snow to KLSE/KRST Friday night with a period of IFR conditions
likely.
