Just happened to look at my wxwugraphs.php page
http://komokaweather.ca/wxwugraphs.php and noticed that in the Monthly for 2014 it shows the Minimal temperature higher than the Maximal and Average for January 5 to 7. I have checked back and this appears to be the only time it has done that. Those were the days of our extreme and record cold days. Screen shot attached
