updated aviation portion for 12z TAF issuance

Short term Today... Tonight... And Tuesday
issued at 404 am cdt Mon may 27 2019
weakening upper trough will move across the region and bring
showers and possible thunderstorms later today and tonight. The
heaviest rain should be in the late afternoon and evening when low
level warm advection is maximized and upper support is best. Any
thunderstorms would be across the southern part of the forecast
area. Clouds and approaching rain will keep high temperatures ten
or more degrees below normal.

The rain will taper off tonight as the upper system moves quickly
to the east. Lows will be close to normal in most places. High
pressure is forecast to build into wisconsin Tuesday with any
showers ending shortly after daybreak. Weak cold advection will
result in highs 5 to 10 degrees below normal.

Long term Tuesday night through Sunday
issued at 404 am cdt Mon may 27 2019
forecast concerns continue to revolve around precip potential in the
Tuesday night through Wednesday night period and whether there is
any threat of heavy rainfall. Will continue to use a blend of the
ecmwf gfs.

Tuesday night through Wednesday night... Low pressure will be lifting
northeast across the central plains while a warm front will be
returning northward over northern illinois on Tuesday night.

Precipitation is expected to be shifting east, north of the warm
front, across iowa and into southwest wisconsin northern illinois in
the evening on the nose of the low level jet. As result, it is
looking more favorable for a dry forecast across most the area on
Tuesday evening. The bulk of the precip will be heading across
southern wisconsin overnight. Central and east-central wi will be
on the northern edge of this precip, and with elevated instability
confined to southern parts of the state, it doesn't leave much
opportunity for thunderstorms or heavy rainfall. Nonetheless, will
keep a chance of rain generally south of hwy 29 late Tuesday night
and Wednesday morning. Forcing will generally diminish through the
day on Wednesday as the approaching shortwave trough weakens.

Because of the slow forward progression of the trough, weak
convergence aloft will continue into Wednesday night, however, so
will only carry over a small chance of rain. No significant changes
to temps.

Rest of the forecast... Models have different ideas in regards to how
quickly the trough exits the region on Thursday. An overall slower
trend keeps troughing overhead on Thursday as well as a chance of
rain. Highest chances will occur over east-central wi. Finally,
guidance indicates the trough exits on Thursday night, which will
set up a period of dry weather Thursday night into Friday. A
northern stream front will then push the next chance of precip
across the area on Friday night into Saturday. Guidance indicates
steep mid-level lapse rates ahead of this front, so it would appear
that there will be a good chance of thunderstorms during this time
period. In the wake of the front, cooler and drier weather is
anticipated to end next weekend.

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.
