Another hot month with average precipitation
With an average temperature that was 1.8 degrees above average, September was the third hotter than average month in a row. But it certainly wasn't consistent warm as the month was a battle between the cold arctic air masses and hotter air from the south. As a result we saw some drastic temperature changes such as a high of 30.5 C on the third and then a high of only 15.5 C two days later.
The precipitation for September was within the average range (95.3 mm compared to an average of 87.5 mm) even though there were 17 days with some measured precipitation, which is more than the average of 12. There were a couple of days with over 20 mm (the 19th and 27th) while the rest of it was was spread over many days with a bit of precipitation here and there.
The total precipitation at the end of September is 799.3 mm, which is still above the average of 680.7 mm for the end of the month.
Summary for September 2011:

Did you mean below? Or a different number in there?
What happened to the lovely graphical summaries of precipitation and temperature that we used to get each month?
I had some major hard drive issues over the past month, but they are fixed now. Hopefully I'll get the last couple of graphical summaries out soon.
To the first comment, yes it should have been 799.3 mm. It has now been changed. Thanks
