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.
Precipitable water 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 County Warning Area.

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.
