Near term (today through tonight)
issued at 213 am edt Sun apr 22 2018

Gradual warning trend continues...

high impact weather potential... None.

Pattern synopsis forecast... Large area of strong high pressure and
dry air remains centered over the great lakes region early this
morning... Resulting in clear skies and dry wx across the great state
of michigan. Clear skies and calm winds are allowing temps to slowly
drop thru the 30s and into the 20s.

For today and tonight... Strong surface high and dry air thru the
column will remain overhead... Maintaining clear and dry wx thru
tonight. Our gradual warming trend will continue today with
afternoon highs warming into the mid 50s to around 60 degrees across
our entire cwa. Low temps tonight will range from the mid 20s across
interior sections of northern lower michigan to the low to mid 30s
across the rest of our cwa.

Short term (Monday through Tuesday)
issued at 213 am edt Sun apr 22 2018

Above normal temperatures...

high impact weather potential: none aside from monitoring rising
river levels through early this week due to snow melt runoff.

Pattern forecast: northern michigan is expected to lie between two
systems slowly meandering across the continent early this upcoming
week. The initial and more potent wave across the southern plains
into the southern ms valley and the second across alberta
saskatchewan. Surface and upper level ridging will gradually slide
east of the area locally Monday into Monday night with weak
southerly moisture advection underway Tuesday combined with an
approaching cold front from the northwest may yield scattered
showers at times across portions of northern michigan.

Primary forecast concerns challenges: pops Tuesday.

Little in the way of sensible weather is anticipated across the
region to start the upcoming week. Another sun-filled day is
expected Monday with high temperatures climbing a few degrees above
normal for most... Ranging from the upper 50s across eastern upper to
the low-mid 60s for many south of the bridge (cooler near the
lakeshores).

Low end chances for rain showers arrive during the day Tuesday,
primarily during the afternoon evening hours as the aforementioned
systems make headway toward the great lakes. Expecting any precip to
be rather scattered brief in nature with most locations staying dry
conditions for the bulk of, if not the entire, day. High
temperatures Tuesday pretty similar to Monday's... .Mid 50s across
eastern upper with low-mid 60s expected to prevail for much of
northern lower.

Long term (Tuesday night through Saturday)
issued at 213 am edt Sun apr 22 2018
high impact weather potential: minimal.

The pattern is expected to become somewhat more active as we head
toward the end of the upcoming week as upper level troughing is
expected to become (at least briefly) carved out across the
midsection of the country. With several perturbations riding along
the periphery of said troughing, occasional chances for rain and or
snow become possible from Thursday through the upcoming weekend
(although plenty of dry time will be mixed in as well).

Aviation (for the 06z tafs through 06z Sunday night)
issued at 1222 am edt Sun apr 22 2018
vfr conditions are expected throughout much of the forecast period.

Some low cloud development is possible near lake huron and the
straits Sunday night.

Marine
Issued at 213 am edt Sun apr 22 2018
winds and waves will remain below SCA criteria thru the early part
of this week as high pressure remains in charge of the wx across the
great lakes region. Dry wx and mainly clear skies are expected...

with a continuation of the gradual warming trend.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
