 FORECAST DISCUSSION

 As we begin the new work week, Michigan is sandwiched between a deep low-pressure system near Hudson Bay and strong high-pressure system centered over the Texas/Oklahoma region.  The tight pressure gradient between those two system guarantee a windy day on Monday.  Wind gusts in the 40-45 mph range can be expected by Monday afternoon and evening.  The front associated with the low-pressure cell could provide some light snow, later in the day, which could be blown around by the strong winds and cause some travel issues.

 An Alberta Clipper is expected to drop down into Northern Michigan Tuesday evening.  Some light snow could accompany that system late Tuesday into Wednesday.

 By Thursday, winds switch to a southwesterly direction and should provide some slight warming under sunny skies.  This is probably the best chance to see some Low Moderates, although that probability appears to be low.

 A low-pressure system moves across the Ohio Valley Friday through Saturday with the track of this system giving us northeast winds going into the weekend.  The majority of precipitation should be to the south of us but some light precipitation in the southern tier counties is not out of the question.

 Air Quality should be mostly Good for the forecast period, although the brief warmup at the end of the week could trigger some scattered Low Moderates.

 EXTENDED FORECAST:

 Air Quality is expected to be mostly Good going into the weekend.
