Update
Aviation(00z tafs)
Gusty northeast winds are expected into the middle evening hours
near lake michigan, with northeast winds persisting into Friday.

These winds will become gusty again by the late morning or around
midday, lingering into the afternoon. Inland areas will see
lighter northeast winds tonight into Friday.

Diurnal cumulus should dissipate by early evening in the western
portions of the area. Middle level clouds to the north may linger
tonight, with some uncertainty as to how far they may move into
the area. For now, kept mostly clear skies and may need to add
more clouds in later on. More diurnal cumulus clouds should
develop inland by Friday afternoon.

Prev discussion (issued 305 pm cdt Thu jul 27 2017)
short term...

tonight and Friday - confidence... High
surface high pressure vicinity of nd NRN mn will drift slowly to
near lake superior. A sustained dry and cooler northeast flow will
keep things quiet into Friday. Low level thermal trough sets up
across the area with 925 temps in the teens celsius. Some more cu
development is expected once again on Friday.

Long term...

Friday night through Tuesday - confidence... Medium to high.

12z suite of model output continues to support a beautiful stretch
of weather for the region, and a welcome break from the
rainy stormy period we have seen over the past several weeks. A
sprawling area of surface high pressure will dominate our weather
regime. Temperatures will be at below average Saturday, slowly
moderating to slightly above average next week with comfortable
humidity levels.

Tuesday night through Thursday - confidence... Medium.

Still some question as to how long this period of dry weather will
persist. The GFS and gem continue to suggest rain chances around
the Wednesday time frame (give or take), while the ECMWF is a day
or so later. Given the spread, confidence in the particulars for
this time frame is a bit lower. Typical summertime temperatures
will persist.

Aviation(18z tafs)...

vfr conditions expected this period as dry surface high builds
towards lake superior. A gusty northeast wind will prevail esp
closer to lake michigan. Quiet and dry regime lasts into Friday as
the influence of the high holds sway. Only some scatteredVFR
diurnally CU is expected on Friday.

Marine...

with high pressure setting up near lake superior a sustained
northeast flow will keep waves up into Friday. So going small
craft advisory looks good.

Beaches...

gusty northeast winds and building waves are expected along the
beaches of lake michigan into Friday. This brings high swim risk
conditions during this time. A beach hazards statement remains in
effect into Friday.

Mkx watches warnings advisories
Wi... Beach hazards statement through Friday evening for wiz052-060-
066-071-072.

Lm... Small craft advisory until 6 am cdt Saturday for lmz645-646.

Small craft advisory until midnight cdt Friday night for lmz643-
644.

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.
