Marine Weather and Tides
Fennville, 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.

Synopsis
Issued at 302 am edt Wed may 23 2018
high pressure will bring fair and warmer weather through Friday.

There will be a few showers and thunderstorms by the weekend as
low pressure approaches.

Update
Issued at 523 am edt Wed may 23 2018
satellite and abs show an area of dense fog across much of
muskegon, kent, ottawa and allegan counties. We will issue a dense
fog advisory for those counties. Parts of oceana, newaygo and van
buren counties may also see patchy dense fog but coverage will be
more limited there.

Short term (today through Friday)
issued at 302 am edt Wed may 23 2018
quiet weather in the short term as sfc ridging prevails and warmer
temperatures as heights rise through the end of the week. There is
a chance of more patchy fog tonight with light winds and good
radiational cooling conditions.

Long term (Friday night through Tuesday)
issued at 302 am edt Wed may 23 2018
it will be very warm and rather humid memorial day weekend with high
temperatures daily well into the 80's and low temperatures mainly in
the 60's. A low pressure system will move slowly east across the
northern great lakes region Saturday into Sunday. It will bring
potential for scattered showers and thunderstorms mainly during the
afternoon evening both days as instability builds. However dry wx
should prevail through most of the weekend.

Warm and fairly humid wx will continue for memorial day into early
to mid next week. There is a small chance for some subtropical
moisture to move up into our region by midweek. This is looking less
likely to happen though as medium range guidance trends suggest a
high pressure ridge will build over the northern great lakes region
early to mid next week which would help to keep the subtropical
moisture pcpn well to the south of our area.

Aviation (for the 06z tafs through 06z Wednesday night)
issued at 1145 pm edt Tue may 22 2018
a mix ofVFR MVFR conditions will deteriorate to a mix of
MVFR with some ifr during the early morning hours Wednesday due
to development of low clouds and more extensive patchy fog. Fog
may become locally dense particularly closer to lake michigan at
kmkg where conditions could deteriorate to lifr.

Low clouds and patchy fog will dissipate during the mid morning
hours Wednesday and conditions will gradually improve toVFR at
all the terminals mid to late Wednesday morning. Conditions will
then remainVFR through Wednesday evening with wind speeds AOB 10
kts.

Marine
Issued at 302 am edt Wed may 23 2018
areas of dense fog will lift by noon with light winds and waves
through the next couple days.

Hydrology
Issued at 1234 pm edt Tue may 22 2018
there will be some rises on area rivers. However, only minor
flooding should occur. We should remain dry until the weekend. This
will allow rivers to recover a bit before rainfall returns.

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.
