Synopsis
Issued at 323 pm edt Tue jun 18 2019
- some patchy fog tonight
- heavy rain should stay south Wednesday night
- warm and humid airmass with thunder and heavy rain possible
Saturday and Sunday

Discussion (this evening through next Tuesday)
issued at 323 pm edt Tue jun 18 2019
a surface cold front moves east from wisconsin into lower
michigan overnight but shower activity should be limited and with
the loss of diurnal heating by the time it reaches our northwest
zones, instability is also rather limited, so thunder chances are
very low. We do have the potential for some fog tonight as winds
will be light and surface dew points are creeping up a bit ahead
of the front.

The front pushes south during the afternoon and a sfc low rides
along it tomorrow night. The heavy rain threat still bears
watching for our far southern forecast area, but most model
guidance has continued to keep the heavy rain axis to the south
across northern indiana and ohio.

After a brief respite, we'll see another period of active weather
over the weekend with a sfc warm front bringing the chance for
thunderstorms Saturday morning. There are some indications of mcs
formation at this time as well, so specific details on how and
where the convection evolves through the weekend are quite murky.

What we are fairly sure of is that the heavy rain threat will
again be with us into early next week with the sfc low moves off
to the northeast and cooler and drier airmass returns, probably by
Tuesday.

Aviation (for the 18z tafs through 18z Wednesday afternoon)

vfr CIGS should continue for the majority of the afternoon as
daytime heating lifts ceilings. Tonight will be very similar to
last night in that we will see the potential for fog -- especially
for azo btl jxn -- into mid-morning alongside MVFR ceilings.

Spotty precipitation chances with potential borderline
MVFR ifr ceilings will then return for the mid-morning hours
starting in north-central mi primarily for mkg, possibly grr
should the frontal boundary shift further southwards. Near the
late morning mid-day time frame daytime heating should begin to
lift these low ceilings into MVFR.

Meanwhile winds will continue to remain light under 10 kts through
the period.

Marine
Issued at 323 pm edt Tue jun 18 2019
winds and waves should remain below 25 knots and 4 feet through
Thursday. There will continue to be areas of fog at times. Some
heavier rain is possible south of grand haven on Wednesday night.

Grr watches warnings advisories
Mi... None.

Lm... 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.
