Marine Weather and Tides
Stephenson, MI

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Short term (this evening through Monday)
issued at 416 pm edt Sun jun 17 2018
biggest concerns for the remainder of this evening into the
overnight period will be the severe threat along with the
potential for additional flooding concerns. Temperatures this
afternoon have warmed well into the 80s across nearly all of the
u.P. With dewpoints in the 60s and 70s. This rather warm, moist
atmosphere, coupled with uncapped instability, increasing 0-6km
shear, and adequate low- and mid-level lapse rates, is opening up
the door for strong to severe thunderstorms to directly impact
portions of upper michigan. Although the severe threat is expected
to wind down by around midnight or so, additional showers and
storms, especially along and ahead of an approaching frontal
boundary responsible for the extra push, could still contain
moderate to heavy rainfall capable of causing additional flooding
problems, particularly for areas already hardest-hit. As for
specific severe threats expected, gusty to damaging winds and hail
will be the primary concerns. While the tornadic threat is low, it
can't be entirely ruled out where storms may interact with
boundaries left behind from earlier convection. Also of note is
that places where the ground is already rather saturated could
have trees come down in sub-severe storms.

Long term (Monday night through Sunday)
issued at 455 pm edt Sun jun 17 2018
once any lingering showers exit the region with the fropa
tomorrow, look for much quieter weather to resume control through
much of the week. Surface high pressure will park itself overhead
Tuesday into early Friday, with the next pattern change arriving
by the end of the week. At this point, models that far out remain
elusive in nailing down anything specific, but the overall pattern
suggests next weekend being the next best chance for showers and
thunderstorms to potentially impact the forecast area. Regarding
temperatures, look for them to linger near normal for this time of
year, with no significant deviations currently anticipated.

Aviation (for the 00z tafs through 00z Monday evening)
issued at 754 pm edt Sun jun 17 2018
shra tsra will be winding down from NW to SE during the night as a
cold front drops across the upper great lakes. Other than some tsra
at ksaw for the next couple of hrs, only -shra are expected at
kiwd kcmx ksaw during the night. In the wake of the cold front, cigs
and or vis will fall thru MVFR to lifr for a time as fog stratus is
advected off lake superior and impacts the terminals. Drier air will
then arrive on mon, resulting in improvement toVFR during the
morning.

Marine (for the 4 pm lake superior forecast issuance)
issued at 430 pm edt Sun jun 17 2018
convection will continue along and ahead of an approaching frontal
boundary with strong to severe thunderstorms expected into tonight.

Winds will stay at or below 20 knots through the forecast period.

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.
