updated aviation portion for 12z TAF issuance

Short term Today... Tonight... And Monday
issued at 318 am cdt Sun jul 22 2018
lingering cyclonic flow and remaining deep moisture across the
western great lakes will keep the chance for light rain showers
across the area today as shortwaves continue to move around a
large upper level low situated over the southern great lakes
region. Modest instability will also remain, however it should
only produce shower activity with a fairly low chance for
lightning as mucapes are less than 500 j kg. This instability
lingers across central wisconsin during the evening hours,
therefore will keep small pops in across this area during that
time period. Periods of Sun will allow temperatures to rise to
around 80 degrees away from the lake this afternoon.

Drier air and shortwave ridging will work their way into the
region later this evening and into the overnight hours, which
should end the chance for rain and bring clearing skies to the
area. Overnight lows are expected to plummet into the 50s across
the north, with lows around 60 degrees elsewhere.

By Monday the ridging flattens out a bit as a low pressure system
approached the upper mississippi valley region. Additional
sunshine will allow highs to rise into the lower to middle 80s
away from the lake.

Long term Monday night through Saturday
issued at 318 am cdt Sun jul 22 2018
pesky upper low that has been hanging around over the ohio
valley and eastern great lakes last few days will continue to
weaken and will eventually get absorbed by broader medium wave
trough forecast to settle over the western great lakes region by
late in the work week. As this transition occurs, broad upper-
level high pressure ridge that has dominated much of the southwest
conus will gradually get suppressed to the desert southwest by
next weekend. This will leave the forecast area generally under
the influence of a broad northern stream trough with occasional
weak shortwave disturbances propagating through the mean trough.

Temperatures will start out above normal during the first half of
the work week, then fall back to near or a little below normal
thereafter.

Main weather impacts will be associated with fairly potent cold
front that will approach the forecast area sometime late
Wednesday. Medium range guidance still struggling on timing and
intensity of primary shortwave to drop southeast into the western
great lakes with the GFS more progressive than the ecmwf. Will
continue to go with a blended solution at this time with best
guess frontal passage sometime around 06z Thursday. Timing of
frontal passage during the overnight hours suggests threat for
severe weather would be minimal. Forecast soundings early Wednesday
evening over central wisconsin suggest somewhat marginal mlcape
in 500 to perhaps 750 j kg range and modest mid-level lrs of
around 6.0 deg c km ahead of the front, while more favorable deep
layer shear lags behind the front. However, given the rather
potent shortwave trough and associated cold front, strong storms
are possible primarily west of the fox valley if models trend
toward a faster solution.

In the wake of the frontal passage, Thursday looks to be a cooler
and rather breezy day with CAA dominating the region. Signals in
the medium range guidance suggest additional shortwave energy to
rotate around primary upper low bringing additional chances for
showers or perhaps isolated thunder especially across the north on
Thursday afternoon. Daytime highs on Thursday will be quite a bit
cooler especially across the northwoods with highs in the lower
70s.

Upper-level trough will continue to influence the forecast area
into the weekend with small chances for showers associated with
any weak embedded shortwave disturbances. Confidence low on timing
of these transient disturbances so will just go with blended
solution of slight chance pops into the upcoming weekend. Max
temperatures during the latter half of the work week and into the
upcoming weekend will be a few degrees below normal for late july
mainly in the 70s.

Aviation For 12z TAF issuance
issued at 620 am cdt Sun jul 22 2018
a large, slow-moving area of low pressure over the ohio valley
will continue to affect northeast wisconsin with scattered
showers and low ceilings this morning. MVFR and ifr ceilings are
expected to persist until the showers move through this morning.

Improving conditions are anticipated after the showers move out,
withVFR conditions returning to most locations by late morning or
early afternoon. Some MVFR or ifr fog is possible across north-
central wisconsin late tonight with clearing skies, mainly
affecting krhi.

Gusty north to northeast winds will continue in eastern wi through
Sunday afternoon, then diminish by sunset.

Kosh Scattered showers will linger this morning as an upper
level disturbance impacts the region. Ifr conditions will persist
until the showers end late this morning. Flight conditions should
improve to MVFR in the late morning, thenVFR in the early
afternoon. North to northeast winds will continue to gust to 15 to
20 knots through this afternoon, then diminish by sunset.

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.
