Friday, September 3, 1999 

While Tropical Storm Dennis continues to deluge the Carolina coast with
heavy rains, the Great Lakes states continue to bask in
sunshine. As long as Dennis continues to spin just off the East Coast, storm
systems will be unable to progress eastward. Thus,
the cold front currently causing scattered thunderstorms throughout the
Rockies and western Plains will not progress very far
east. This system is expected to move into the Plains states on Saturday but
continue to have no effect on our weather. Dennis is
predicted to weaken throughout the weekend and this should allow some relief
to move into the Lake Michigan states on
Monday. Until then, ozone concentrations will continue to climb above 100
ppb in many locations and caution should be
excercised while enjoying outdoor activities. Temperatures will climb to
near 90 on Friday and Saturday with humidities causing
the heat index to be well into the 90s. After another morning of patchy
dense fog, Saturday afternoon skies will become mostly
with only light southerly winds. 
This forecast will be updated on Saturday 04 September 1999.

This smog observer was temporarily distracted and was reminded by 
colleague David Dempsey that there is a smog episode going on

As of 10 PM EDT, Friday the most polluted place in Michigan is
Benzonia up near the Sleeping Bear Dunes with an 8 hour average
of 101 ppb, and the second most polluted is Houghton Lake at 87 ppb

Today's ozone results will likely show health standard violations at:

Benzonia, Lansing, Houghton Lake, Coloma, Scottville, Rose Lake, 
Otisville, Ann Arbor (probably), Port Huron, Detroit (e 7 mile), 
Cassopolis and Evans

www.epa.gov/airnow is showing that Michigan had the high proportion
the state showing areas unhealthy for sensitive individuals and that
smaller but still significant areas of both Michigan and Missouri 
showed smog concentrations into the higher unhealthy for everybody 

Friday's highest smog was monitored from Scottville to Benzonia
and extending through Wisconsin's Door Peninsula and modelled
into the Menominee to Escanaba area.

Airnow is showing that Michigan, Missouri and Wisconsin had the 
highest smog of any place in the midwest for Friday.


Yesterday's (Thursdays) results show health standard excursions at
the majority of monitoring sites in the state:  (85  ppb is the level of the
8 hour standard)

Benzonia  96
Scottville 96
Muskegon 92
Holland 91
Coloma 87
Jenison 91
