Area Forecast Discussion
National Weather Service La Crosse WI
334 AM CDT Thu Sep 29 2016

.SHORT TERM...(Today through Friday night)
Issued at 334 AM CDT Thu Sep 29 2016

Pesky closed low situated over southern Indiana early this morning
with a ridge of high pressure folding into our region from the
Plains. this was resulting in partly cloudy skies across our area
with temperatures hovering in the upper 40s/lower 50s.

Ridge of high pressure holds strong across the region today for
mostly sunny and pleasant conditions. Look for high temperatures
to end up right around normal in the 65-70 degree range.

Clouds spread into the area from southeast to the northwest after
midnight tonight as that pesky closed low swings a trough/lobe of pv-
advection toward the area. Showers look to hold off to the southeast
though.

Scattered showers to invade the area Friday into Friday night mainly
east of the Mississippi river as we slip back under the influence of
the cool cyclonic flow of that mid-level low and forcing from
another lobe of pv-advection.

Temperature-wise, look for lows tonight and Friday night in the 50s
with highs Friday topping off in the 60s.

.LONG TERM...(Saturday through Wednesday)
Issued at 334 AM CDT Thu Sep 29 2016

Area remains in the deep/cool cyclonic flow into Saturday as the
closed low begins to lift toward southern Lake Michigan. Result will
mostly cloudy skies with scattered showers once again mainly east
of the Mississippi River.

Cyclonic flow loses its grip on the area Sunday as the closed low
begins to fill and lift northeast across lower MI. Look for mostly
cloudy skies in the morning, then more sunshine in the afternoon.
Plan on highs in the 65-70 degree range.

Monday through Tuesday shaping up to be a couple pleasant days as a
ridge of high pressure slides into the region. With more
sunshine...highs are expected to top off in the middle 60s to the
lower 70s.

Shower and thunderstorm chances edge into MN/IA/western WI Tuesday
night into Wednesday in advance of low pressure pushing through the
Plains.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1032 PM CDT Wed Sep 28 2016

VFR conditions at the moment, but still watching to see if we can
muster some fog development around RST prior to sunrise. Model
guidance of all varieties is insistent on fogging in that
terminal, but at the moment, stronger surface winds prevail at
10-12 knots. Still seeing some hints winds may slacken a bit later
tonight, but don`t feel comfortable carrying anything lower than
2SM at this time. As for LSE, just seeing too much wind above the
inversion to allow for any fog (and probably even stratus)
development at the terminal proper. After 14Z, should see
widespread VFR conditions with mainly clear skies (perhaps a touch
of cumulus?) and northerly winds 10-15 knots, subsiding toward
sunset.
