Mariners can expect gusty winds to around 30 knots, locally higher waves, and lightning strikes. Boaters should seek safe harbor immediately until these storms pass. This strong Thunderstorms will likely produce winds to around 30 knots, and could pose a serious hazard for boaters. A special marine warning may eventually be required when these storms reach the nearshore waters. Boaters should consider heading for shore before these storms arrive. && lat...lon 4500 8353 4513 8341 4528 8350 4543 8394 4544 8411 4560 8434 4605 8473 4609 8460 4604 8413 4605 8412 4612 8417 4617 8434 4624 8411 4606 8395 4612 8382 4611 8358 4599 8344 4582 8359 4534 8252 4504 8246

645 am edt Tue jul 23 2019

Near term (today through tonight)
issued at 335 am edt Tue jul 23 2019

Small chances of showers and storms today into early evening...

high impact weather potential... Minimal. A few non-severe
thunderstorms may develop this afternoon in our SE cwa.

Pattern synopsis forecast... Large area of surface high pressure
remains parked over the heart of the us early this morning... With
overall surface ridging extending eastward thru much of the great
lakes region. Upper level trough axis is holding across the NE us...

keeping our temps a few degrees above normal. A moisture-starved
cold front is draped across southern ontario... With a weak wave
riding thru lake superior and upper michigan attm. This wave will
continue to drop SE thru the upper level trough in place across the
great lakes... Providing some scattered shower activity to our cwa
thru the morning hours. The wave will not clear our CWA until early
evening.

Lift and synoptic moisture from this wave combined with building
diurnal instability will provide a chance of showers and storms to
the SE half of our CWA this afternoon and early evening. Latest nam
boosts mlcapes to around 750 j kg within this region during peak
heating today. Wind fields will remain relatively light... And with
limited instability and moisture... Our chances of any severe storms
are very low for today. Any precip chance will come to an end with
loss of diurnal instability this evening... And as the wave exits the
region.

Temps will remain very pleasant... But generally a few degrees below
normal thru tonight. High temps this afternoon will warm into the
70s again. Low temps tonight will cool back into the 50s.

Short term (Wednesday through Thursday)
issued at 335 am edt Tue jul 23 2019

Temperatures and humidity slowly on the rise...

high impact weather potential... Low.

Primary forecast concerns... A popup shower or storm.

Ridging aloft will build slowly into the region from the south and
west. This should help keep the region rain free, though chances are
not at zero and would not be totally shocked if something were to
pop up. Humidity levels will inch up into the moderate range. Expect
 temperatures to be close to climatology Wednesday then rise to a few
degrees above on Thursday.

Long term (Thursday night through Monday)
issued at 335 am edt Tue jul 23 2019

More humid with shower and thunderstorm chances...

high impact weather potential... Low.

A nearly zonal flow for much of the period as a trough moves by to
our north across central canada. Another trough looks like it tracks
farther south early next week. So overall very warm and humid
conditions with chances for showers and a couple of storms, though
nothing widespread or long lasting is anticipated (at least through
the weekend anyways).

Aviation (for the 12z tafs through 12z Wednesday morning)
issued at 645 am edt Tue jul 23 2019
a weak wave will slide thru northern michigan today... Producing a
few showers this morning and scattered showers and thunderstorms
mainly SE of a line from apn to htl this afternoon. Overall
conditions will remainVFR at all TAF sites thru the next 24
hours... But may briefly drop to MVFR within any heavier showers or
storms that develop. Also... Some patchy fog ifr conditions around
mbl early this morning will mix out over the next couple of
hours. NW winds will strengthen to 10 to 20 kts this afternoon...

and will then become light variable after sunset tonight.

Marine
Issued at 335 am edt Tue jul 23 2019
winds and waves will remain below SCA criteria today thru Wednesday
as overall low level ridging remains in control of the wx across
northern michigan. A weak wave will drop thru our area today...

providing small chances of showers and storms today thru early
evening.

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.
