E-M:/ Saturday Smog

Enviro-Mich message from "Alex J. Sagady & Associates" <ajs@sagady.com>

Saturday wasn't supposed to be an ozone action
day and ozone buildup was delayed this morning
as a result of cloudy conditions, but this
afternoon's hot weather has nevertheless lead
to high ozone in some locations.

At 3, 4 PM, these notable 1 hr readings are noted:

Muskegon   123 ppb
Holland    108 ppb
Warren  110 ppb
Oak park   105 ppb
Kalamazoo  99 ppb
Detroit 7 mile   93 ppb



An Ozone Action! Day advisory has been issued for Sunday, June 23rd.


  An Ozone Action! Day advisory has been issued for Sunday, June 23rd.


A cold front responsible for triggering scattered thunderstorms from 
Michigan north-westward to Minnesota over the past day and a half will now 
lift northward as a warm front. Current radar shows a batch of showers and 
thunderstorms moving across northern lower Michigan and heavier 
thunderstorms over central and northern Wisconsin. Cloud cover over much of 
the state this morning, will begin to break up as the day wears on with 
southern counties experiencing the greatest amount of sunshine. The 
atmosphere should remain unstable enough today that the chance for 
thunderstorms will exist into the evening hours. Temperatures will vary 
across the state with daily maximums in the upper 70's in northern portions 
of the state and low to mid 80's where the sun in more prominent. Due to 
the presence of cloud cover and chances for precipitation, ozone levels 
should remain in the good to moderate category today.

Under the influence of building high pressure, temperatures aloft will 
begin to warm over the next day, resulting in a subsidence inversion. This 
inversion will likely suppress any threat for precipitation as we head into 
Sunday and Monday. Maximum surface temperatures for Sunday and Monday are 
forecasted to be in the 90-95 degree range under mostly sunny skies. Winds 
will mainly be light (5-10 knots) and from the west-southwest. Chances for 
precipitation increase as we head into mid-week, with temperatures 
remaining warm and the airmass moist.


Mostly sunny skies and temperatures soaring into the 90's raise concern for 
unhealthy levels of ozone in Michigan on Sunday. As a result, the Michigan 
Department of Environmental Quality is issuing an Ozone Action! Advisory 
for Sunday, June 23rd. As this hot and sunny weather continues into Monday, 
concern for elevated levels of ozone will be reevaluated tomorrow.
