updated aviation portion for 12z TAF issuance

Short term Today... Tonight... And Monday
issued at 344 am cdt Sun jun 16 2019
unsettled cool pattern continues today with chances of rain showers
through early this afternoon. Below normal temperatures will
continue through the weekend, but temperatures will moderate for the
day Monday.

Water vapor imagery shows a weak shortwave passing through the area
this morning, while IR and surface observations show widespread
cloud cover across much of wisconsin. Radar imagery shows scattered
rain showers from around marathon county to brown county drifting
slowly to the east and northeast. Otherwise, temperatures were
running in the 40s to low 50s across northeast wisconsin.

Today: a surface low pressure center will slide from northern
illinois this morning to or near northern indiana by this afternoon
while weakening. In addition, an 850mb theta-e gradient will stretch
west to east across central into east-central wisconsin. Aloft, a
weak shortwave will pass through the area as well, but the trend has
been for the wave to flatten throughout the day. Still, there will
likely be enough forcing and maybe some weak instability
(central east-central) to produce some scatterd rain showers. The
best chance of seeing the rain showers will be along the
aforementioned theta-e gradient throughout the day as the better
forcing will be in that area. The northern portion of the area will
be closer to a drier high pressure center, helping to limit coverage
of the rain showers. The increased cloud cover will lead to cooler
temperatures throughout the day, the exception will be farther north
close to the upper michigan border where clouds may break up a bit
earlier. Most locations are expected to remain in the low to mid 60s
for daytime highs; however, northern locations may see highs warm
into the low 70s. The added east to northeast flow off lake michigan
will also help to keep temperatures down closer to the shoreline.

For a comparison, average temperatures this time of year are right
around the mid 70s.

Tonight into Monday: the surface ridge is expected to expand
southward across the area tonight into Monday as the flow becomes
more zonal aloft. This will allow for a brief break in the
precipitation and unsettled weather. Skies are expected to become
clear to partly cloudy across the area with high temperatures
expected to warm into the 70s for Monday, while overnight lows drop
into the 40 tonight.

Long term Monday night through Saturday
issued at 344 am cdt Sun jun 16 2019
zonal flow at 500mb expected through much of the work week,
then should transitions to a more active southwest flow
pattern next weekend. Temperatures during the period should
be at or slightly below normal for the latter half of june.

A cold front is expected to approach the area Monday night,
bringing a chance of showers and storms. Model differences
in the timing of the front has created the chances of showers
or storms Tuesday and Tuesday night. Current chances of rain
account for the timing differences in the models. As we get
closer to the event, will probably shorten the time for the
chances of rain. Chances of rain continue Wednesday. It now
appears that later Wednesday night and Thursday may actually
be dry based on the latest ECMWF canadian models. Since we
are still several days out, will continue the small chances of
rain just in case the ECMWF canadian models change their tune
on the dry weather.

Friday into next weekend, models indicating a more active
pattern with the chances of showers and thunderstorms, more
likely next weekend at this point. It is possible that stronger
storms are possible next weekend, but it is too early to determine
the severe potential. With clouds or the chances of rain at times
during the period. Temperatures are expected to be at or slightly
below normal. If we do get one of those days with a thick cloud
cover, rain and easterly winds temperatures should be considerably
cooler than what is advertised.

Aviation For 12z TAF issuance
issued at 627 am cdt Sun jun 16 2019
a cold front or nearly stationary front will linger across
southern wisconsin today. The close proximity of the front along
with a weak upper-level disturbance pushing through the area, will
lead to scattered rain showers and some MVFR ceilings through
early this afternoon. A few scattered lower ceilings are possible,
especially toward atw and mtw. Farther north,VFR conditions are
expected to prevail through this TAF issuance. Improving
conditions can be expected at all TAF sites this afternoon into
tonight.

Grb watches warnings advisories
None.

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.
