At 11:00 AM, it was 69°F in Champaign, with overcast skies at 1300' and a south wind at 15 mph. (The forecasts through last night did NOT predict the fog, mist and overcast we've seen this morning.)
Conditions are not acceptable for flying right now due to the low ceiling. However, this is forecast to clear in the next couple of hours - but will be followed by wind gusts up to 29 mph by 3:00 PM.
Considering all this, today's launch is (reluctantly) canceled.
