FIRST, THE WEDNESDAY WEATHER HEADLINES

–High altitude smoke off Western wildfires is behind the orangish cast to the sky Wednesday

–Wednesday’s high temp hit 78—-the normal is 76.  So, today’s temp was about “on the money”

–Nighttime cooling may lead to some patchy fog again tonight—much as it did last night–despite the limited amount of moisture in the air

–No rain until a few isolated, low coverage showers or thunderstorms arrive on the scene between Sat night & Sun night–but coverage of the Chicago area will fall in the 20 to 30% range

–TEMPS ARE TO CONTINUE WELL ABOVE NORMAL—AVERAGE 10 to 15-deg above each day from Friday through next Wednesday.  Cooling arrives late week after the official astronomical start of autumn with takes place Thursday next week at 8:04pm.

–MODELS HAVE PULLED BACK ON THE 90-deg temps suggested for Sunday and Monday. A weak front shifts winds off the lake Monday and is behind the lower temps predicted.

–BUT TEMPS NEAR OR AT 90 still appear a possibility Tue and Wed next week
