Area Forecast Discussion
National Weather Service La Crosse WI
1143 PM CDT Fri Mar 24 2017

.SHORT TERM...(This evening through Saturday)
Issued at 325 PM CDT Fri Mar 24 2017

At 3 PM, light to moderate rain was falling across central
Wisconsin and across east-central Iowa. The northern area of rain
was associated with an area of strong 850 to 700 mb
frontogenesis. Meanwhile the southern area was along and ahead of
a surface cold front. Temperatures were in the mid and upper 30s
north of Interstate 94, in the 40s across northeast Iowa and west-
central and central Wisconsin, and in the 50s in southwest
Wisconsin.

For tonight, an area of light to moderate rain will be found
mainly south of Interstate 90. This rain will be associated with
moderate to strong 900 to 800 mb frontogenesis. Rainfall totals in
this area will be up to a third of an inch.

On Saturday, a moderate to strong band of 900 to 700 mb
frontogenesis will move north and west across the area. This band
is rotating around the upper level low which is moving slowly
northeast across Missouri. Additional rainfall totals will be up
to a tenth of an inch north of Interstate 90 and from a tenth to a
third of an inch across the remainder of the area.

.LONG TERM...(Saturday night through Friday)
Issued at 325 PM CDT Fri Mar 24 2017

From Saturday night into Sunday, the upper level low will move
east northeast across central Illinois and the lower Great Lakes.
Wrap around moisture will keep a chance of rain through this time
period. Additional rainfall amounts will be up to a tenth of an
inch. With temperatures expected to be near freezing across
north-central Wisconsin, there may be a brief bout of freezing
rain on Saturday night. Confidence is very low on this, so there
was no talk of a potential Winter Weather Advisory.

From Monday into Wednesday, a ridge of high pressure will provide
dry weather across the region. High temperatures will range from
the upper 40s to upper 50s and the low temperatures will be mainly
in the 30s.

For the end of next week, there is much uncertainty on the track
of an upper level low through the Mid and Upper Mississippi River
Valley. Due to this, kept the precipitation and temperatures near
the model consensus.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1143 PM CDT Fri Mar 24 2017

Lower end MVFR to IFR conditions continue across the region, and
little will change the next 24 hours with low pressure drifting by
to the south. Winds will become gustier with time from the
northeast, with some gusts pushing 25 knots possible at RST later
this afternoon. Occasional light showers could impact just about
any location overnight, with a better chance for scattered to
numerous showers arriving this afternoon and evening.
