.AVIATION...

Low pressure now over Quebec has left broad cyclonic flow in place
across the Great Lakes. Low VFR ceilings and breezy west flow (gusts
to 30 knots) will persist through the remainder of the afternoon
before conditions improve tonight as winds subside and skies clear.
Any clearing will be brief tonight before a quick-hitting clipper
arrives early Monday morning. This system lacks deep moisture, but
should have enough instability and lake enhancement to produce a
window of rain and/or snow showers between roughly 08z and 14z. The
instability component of this system results in variable
precipitation rates and p-types, so expect cig/vsby restrictions to
be variable throughout the morning as well. Additional scattered
rain-snow showers remain possible in the afternoon as boundary layer
instability stays in tact.

.DTW THRESHOLD PROBABILITIES...

*   High for ceiling at or below 5000 ft through this afternoon. Low
    this evening. Medium Monday.

*   Moderate for ptype to be rain/snow mix Monday morning and Monday
    afternoon.
