Synopsis
Issued at 320 pm edt Thu aug 22 2019
- cooler than normal weather into Saturday
- dry through the weekend
- some showers and possible thunderstorms Monday into Tuesday

Discussion (this evening through next Thursday)
issued at 320 pm edt Thu aug 22 2019
we are generally looking at a quiet weather pattern through the
weekend with high pressure in control. It does look like the
airmass will be cold enough to support some added moisture from
the great lakes through Friday. The main impact of this would be
skies going broken during the afternoon as temperatures climb
above 70 degrees. These afternoon clouds may hold back
temperatures a few degrees each day. Tonight... Good radiational
cooling is expected so normally colder locations like leota up in
clare county may fall into the 30s. Elsewhere mainly 45 to 55
should prevail for low temperatures.

On Monday a warm front will track into the region from the south.

Pwat values climb to 1.75 to 2.00 inches as we go into Monday
night. Some showers and thunderstorms could accompany the arrival
of this front. Then as a mid level wave and associated cold front moves
in from the west Monday night into Tuesday additional showers and
thunderstorms are possible. It does look like by Tuesday evening
the bulk of the activity should be east of the cwa.

once the Sun sets skies will clear and stay that way through
Friday. Winds will be out of the northeast between 5 and 10
knots. Muskegon will have a lake breeze tomorrow afternoon so
winds there will turn the northwest by 18z or so.

Marine
Issued at 320 pm edt Thu aug 22 2019
generally quiet weather into the weekend with no hazards expected.

Monday into Tuesday building winds and waves are forecasted as the
next storm system moves in. Conditions could become hazardous.

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.
