Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI

Tonight through Thursday...Forecast confidence is high.

Generally quiet weather is expected. The one problem for Wednesday
into Thursday will be the increasing west to southwest winds. Low
pressure to our north and high pressure to the south, puts us
squarely in a tight pressure gradient. We should see sustained
winds of 15 to 20 mph with gusts to 30 and possibly 35 mph up
toward Sheboygan for Wed afternoon into Thursday. This should
result in considerable drifting snow, causing difficult travel,
especially in the more north/south oriented roads.

Temperatures will be in the 20s on Wednesday, warming into the
lower and mid 30s on Thursday with the milder southwest flow.

Friday and Saturday...Forecast confidence is high.

Our quiet and progressively milder trend will continue as the flow
turns more zonal then southwest with time. We could have highs in
the lower 40s by Saturday.

Sunday and Monday...Forecast confidence is medium.

The long range guidance has a storm system rolling through the
Upper Midwest later in the weekend into early next week. Both the
GFS and the ECMWF have the track pretty far to the west and north,
thus we get into the warm sector of this storm. Timing is off a
bit from each model, but not bad for this far out. High temps in
the 40s through the weekend would result in a wintry mix early,
transitioning to rain, then back to snow. It`s a very long way off
in the meteorology world and this track will continue to
fluctuate with time. But, right now, this is not a big snow
producer for southern Wisconsin. Stay tuned.



VFR conditions are expected through the TAF period. Look for
northwest winds to gradually back to west to southwest on
Wednesday. Winds by Wednesday afternoon could be gusting 20 to
near 30 mph. This will cause considerable drifting of snow that
airport operations will likely have to deal with.


Increasing west to southwest winds Wednesday through Thursday will
result in small craft advisory conditions.


LM...Small Craft Advisory from 9 AM Wednesday to 3 PM CST Thursday
     for LMZ643>646.
