forecast discussion for routine afternoon forecast issuance

Short term Tonight and Sunday
issued at 254 pm cdt Sat oct 19 2019
the latest rap analysis and satellite radar imagery show a cold
front moving across wisconsin early this afternoon. A band of rain
is accompanying the front, within a region of mid-level fgen and
moisture convergence. This rain is moving across areas from
rhinelander to wisconsin rapids and will slowly track east into
northeast wisconsin by late afternoon or early this evening.

Clearing skies are moving across eastern minnesota behind the
front. Forecast concerns generally revolve around precip trends
and potential for dense fog late tonight.

Tonight... The cold front will continue to march east and move into
lake michigan by roughly 06z. The short range models generally
show the band of rain weakening as it moves into the eastern part
of the state due to diminishing mid-level fgen. Skies remain
expected to quickly clear behind the front, with a weak surface
ride axis settling across the region. Because of the clear skies
and light winds, conditions will support fog formation late
tonight. Statistical guidance has appeared to have backed off on
the fog potential, but the href hits central and north-central wi
relatively hard. This makes sense as these areas will see the most
rainfall and coolest temps today. Locally dense fog appears
possible in this area. Lows tonight are expected to fall into the
mid 30s over north-central wi to the mid 40s near the lakeshore.

Sunday... Morning fog may persist until 9 or 10 am. Otherwise,
should see a nice fall day with only high clouds invading the
region from the southwest during the afternoon. Temps will be mild
and range from the upper 50s to low 60s for most locations.

Long term Sunday night through Saturday
issued at 254 pm cdt Sat oct 19 2019
the negatively tilted upper trough over the northern plains will
intensify as jet energy continues to rotate around it Sunday night
through Tuesday as it lifts slowly northeast towards the minnesota
arrowhead and then northern lake superior.

Dry air ahead of the system should keep the forecast area dry at
least through the early morning hours Monday. Gulf moisture should
arrive during the day Monday and produce an inch or so of rain in
most areas, with perhaps more across central and northern counties.

There could be a few thunderstorms south of a green bay to wausau
line with elevated instability. Temperatures Sunday night will be
held above normal due to cloud cover. Highs Monday should be a
few degrees above normal with southerly winds bringing in warmer
air from the south.

As the surface low intensifies Monday night and Tuesday, gusty
west winds will bring slightly colder air into the region, along
with showers. The air aloft doesn't appear cold enough for anything
but rain at this time. Gale force wind gusts are possible late Monday
night through Tuesday. Mainly dry and cool weather should follow
for Wednesday through the end of the week.

Aviation For 18z TAF issuance
issued at 1137 am cdt Sat oct 19 2019
along a weak cold front, a narrow band of rain showers will move
from west to east across the forecast area through mid-evening.

Flight conditions should deteriorate to MVFR for 2 to 3 hours in
the showers. Behind the band of rain, ceilings quickly rise to
vfr.

Skies are expected to clear out behind the front, which will cause
ground fog to develop late tonight. Statistical guidance is
generally not supportive of widespread dense fog, but not willing
to give up on ifr vsbys just yet given the favorable conditions.

Locally lower vsbys will remain possible.

Any fog should dissipate relatively quickly in the 13-15z time
period, which will leaveVFR conditions for the rest of the day.

Grb watches warnings advisories
None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
