Near term (tonight through Wednesday)
issued at 303 pm edt Tue oct 17 2017

Breezy and warmer on Wednesday...

high impact weather potential... None.

Pattern synopsis forecast... Great lakes remain locked between strong
high pressure centered over the ohio valley and strong low pressure
centered over james bay. Tight low level pressure gradient between
the two is producing gusty SW winds across michigan. Temps have
warmed into the 60s as expected thanks to strengthening low level
waa. Only some scattered cirrus is drifting over our CWA attm.

Upstream surface ridge axis will slide over our CWA this evening...

pushing east of our area overnight. Further strengthening of low
level flow and WAA on the backside of the surface ridge axis will
increase wind speeds on Wednesday as well as boost temps into the
mid to upper 60s on Wednesday. Otherwise... Dry wx and mainly
clear skies will continue thru Wednesday.

Short term (Wednesday night through Friday)
issued at 303 pm edt Tue oct 17 2017

Remaining on the mild side...

a moisture starved cold front will move through northern michigan
late Wednesday night. This front will do little except for to limit
high temperatures to the upper 50s to middle 60s Thursday, which is
a few degrees cooler than Wednesday but also still a few degrees
above average for the third week of october. One thing to watch
though is the possible formation of over lake instability induced
clouds late Wednesday night into early Thursday (it's a close call
on this one). Ridging at the surface and aloft then builds in during
the day Thursday into Friday. This will lead to warmer temperatures
once again Friday with highs ranging from the middle 60s north to
the lower 70s south. Winds will remain in the breezy category due to
a respectable surface pressure gradient. This wind should keep lows
at night in the upper 30s to middle 40s.

Long term (Friday night through Tuesday)
issued at 303 pm edt Tue oct 17 2017
high pressure will remain over the region through the first part of
the weekend, before an approaching cold front moves into the region
possibly as early as Sunday. This will bring the next shot of
precipitation, with a clipper system set to move in quickly behind
the front. This clipper will provide a reinforcing shot of cold air,
increasing the amplitude of troughing from the great lakes
eastward. This will usher in the first real cold airmass of the
season towards the middle of next week. May see snow sneaking into
the extended with tomorrow's issuance.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 805 pm edt Tue oct 17 2017
with high pressure nearly across the ohio valley... SolidVFR
conditions continue across northern michigan through the upcoming
taf period. Winds will briefly diminish this evening... But begin
to ramp back up later overnight and on Wednesday. This will lead
to another period of llws conditions at the terminal sites toward
Wednesday morning... And gustiness through the day Wednesday.

Weak-ish cold front will slide through the region Wednesday night
(beyond the current TAF period) and may bring a brief period of
lower cloud cover to the region.

Marine
Issued at 303 pm edt Tue oct 17 2017
winds and waves will continue to reach SCA criteria tonight into
early Wednesday as low level pressure gradient remains rather tight
between high pressure centered over the ohio valley and low pressure
centered over james bay. Conditions may reach gale warning criteria
across our lake michigan nearshore areas by midday Wednesday as the
low level gradient further tightens on the backside of a departing
ridge axis. Overall dry wx is expected to continue for all of our
nearshore areas thru the workweek.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
