Synopsis
Issued at 322 pm edt Sun sep 24 2017
high pressure will continue to control our weather for the next few
days. Record heat is expected Monday and perhaps Tuesday. Cooler
weather will arrive mid week after a strong cold front moves
through. Unfortunately, appreciable rainfall isn't expected. But,
highs will fall into the 60s by the end of the week.

Short term (this evening through Tuesday night)
issued at 322 pm edt Sun sep 24 2017
forecast concerns are minimal this afternoon. Record highs are a
pretty good bet Monday and possibly Tuesday too. We'll be well into
the 90s Monday with high pressure both at the surface and aloft. The
ridge finally begins to move east Tuesday, but hot temperatures in
upper 80s are still anticipated with records within a degree or two.

The best chance of rain will be late Tuesday as a strong cold front
moves through. Unfortunately, the short wave driving this front will
remain closer to the u.P. And we won't see much rainfall. The 3km
nam does show a diminishing line of convection 00z Wednesday just
offshore, but then weakens it as it moves east. So, there's a chance
we could see some rain, but not a high chance.

Long term (Wednesday through Sunday)
issued at 322 pm edt Sun sep 24 2017
no relief to the drought is in sight. We have a decent shot at some
showers late Thursday night into Friday as the upper trough and
chillier air impacts the region, but highest QPF amounts will
probably be only one tenth to one quarter inch if that.

The push of cold air late in the week looks very short lived. The
upper trough moves out quickly on Friday night with ridging becoming
re-established both aloft and at the sfc Saturday. H8 temps are
progged to be moderating already on Saturday (from the northwest) as
a large surface high settles directly over the region. We get on the
back side of that surface high Sunday, and the return flow should
lead to further warming and continuation of dry weather.

Aviation (for the 00z tafs through 00z Monday evening)
issued at 823 pm edt Sun sep 24 2017
vfr conditions continue through the overnight except some 4 to 6
mile visbys in light fog between 10z and 12z. ThenVFR for Monday.

Winds will be light overnight then south AOB 10 knots.

Marine
Issued at 322 pm edt Sun sep 24 2017
no marine issues. High pressure nearby will result in waves AOB 1
foot for the next couple of days.

Hydrology
Issued at 1245 pm edt Sun sep 24 2017
rivers are running around normal to below normal for the time of
year. Meanwhile, the us drought monitor is indicating dry conditions
across southern lower michigan. Near-record warmth is expected today
and Monday. The next chance for rain is Wednesday, but it's not a
good chance. No river issues are expected through the week.

Climate
Issued at 322 pm edt Sun sep 24 2017
the heat wave will continue into Tuesday and more records are likely
to be set. The following are record highs for Monday and Tuesday:

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.
