updated aviation portion for 06z TAF issuance

Short term Tonight and Wednesday
issued at 342 pm cdt Tue jul 16 2019
the main forecast challenge will continue to be precipitation
trends as the atmosphere is ripe with moisture, just waiting for a
trigger to set more thunderstorms.

The 19z msas surface analysis showed a very weak cold front that
extended from eastern upper mi southwest through east-central wi,
to southwest wi. So far, no precipitation had developed on this
front and the cumulus field on visible satellite has showed no
trends of building. Of more interest was a cluster of
thunderstorms over south-central mn north-central ia which are the
remains of a mesoscale convective-induced vorticity (mcv). This
feature had a northeast movement and could impact central east-
central wi later this evening.

The cold front is forecast to sag into southern wi tonight and
pull up stationary as it become parallel to the mean flow aloft.

Meanwhile, the MCV is projected by meso-models to move into
central southern wi this evening before dissipating. Have
therefore placed small pops over this part of the forecast area,
mainly for the evening hours. Do not anticipate any severe storms
due to weak shear, however any precipitation would produce heavy
rain with pw values of 1.5-2.0 inches. Min temperatures to range
from around 60 degrees far north, to the upper 60s to around 70
degrees south.

It is looking like Wednesday morning will be quiet with the
stalled boundary to the south and the next system still over
the northern plains upper ms valley. However, the boundary is
progged to start lifting north as a warm front and a convective
complex associated with a cold front mid-level shortwave to sweep
into the upper ms valley Wednesday afternoon. The air mass will
destabilize over northeast wi in the afternoon with mucapes
reaching 1.5-2.5k j kg over central wi. 0-6km bulk shear reach
35-45 knots which is more than sufficient to support updrafts and
allow for a potential of stronger storms to move into parts of
the area later in the day. Pw values remain very high (1.5-2.0
inches), thus damaging wind gusts and torrential downpours would
be the main threats, mainly over central wi toward evening. Max
temperatures on Wednesday to be in the upper 70s to lower 80s near
lake mi, lower to middle 80s north and middle to upper 80s south.

Long term Wednesday night through Tuesday
issued at 342 pm cdt Tue jul 16 2019
the main concerns in the long term are the combination of heat and
humidity, potential for severe storms, and possibility of excessive
rainfall.

Models already had consistency issues in their handling of
thunderstorms on Wednesday night into Thursday. Heaviest rainfall
occurs over central and east-central wisconsin according to the
12z NAM but the 12z ecwmf had it mainly to our north, with another
maximum to our south.

Rapid mid level flow continues across the region into the
weekend. This will allow temperatures to warm up quite a bit
during the daytime, with the exception of any cloudy and rainy
days. Friday looks to be the day that will have the highest heat
index values, with some locations reaching the 100 to 105 range.

A cold front is expected to pass across the region late in the
weekend, bringing cooler and less humid air to the area for early
next week.

There are plenty of chances for storms through the weekend in the
warm humid air, and also with the passing cold front.

Aviation For 06z TAF issuance
issued at 1101 pm cdt Tue jul 16 2019
mostlyVFR conditions are expected tonight through Tuesday.

Some dense fog may straddle the lake michigan shore but should
remain east of mtw and sue. Patchy ground fog is also possible
just before sunrise across the remainder of the region.

The oshkosh TAF will available for the next two weeks.

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.
