So far, June's chill is one for the records

The cloudy, chilly and rainy open to June here has been the talk of the town. So far this June is running more than 12 degrees cooler than last year, and the clouds, rain and chilly lake winds have been persistent. The average temperature at O'Hare International Airport through Friday has been only 59.5 degrees: nearly 7 degrees below normal and the coldest since records there began 50 years ago.

More bad weather is on the way Saturday with a cold rain expected to linger through the bulk of the morning. Rainfall could be heavy -- especially north of the city, which would be a reversal of Thursday's deluge that targeted the southern suburbs.

Makes one to wonder how much of this is due at least in part to Redoubt Volcano (http://talk.livedaily.com/showthread.php?t=655328).

Looks like we now have yet another volcanic plume adding more sulphur dioxide (a white aerosol that reflects sunlight) to the atmosphere in the northern polar regions (polar regions are extremely sensitive because of the angle of sunlight) to help turn the thermostat down even more in the northern hemisphere during the upcoming months ahead.
