October 2008 Summary

A dry month with average temperatures

It must be fall with the battles between cold air from the north and warm air from the south, this showed up in the temperature record with lots of days that were either well above or well below average. But as often happens in this case, they cancelled each other out and we are left with an overall temperature within the average range (0.3 degrees below average for the month).

For the first time since April, we had a below average month for precipitation. Only 45.0 mm fell during October in lots of small storms throughout the month with only 1 day having double digit precipitation (11.2 mm on the 8th).

We have now had 907.9 mm of precipitation this year compared to the average of 754.9 mm for the end of October. So even if we don't get anything in November and December, we have now surpassed the average annual precipitation for the area (904.1 mm). However, we have slipped down to being the 8th wettest first 10 months of the year from the 5th wettest first 9 months of the year.

Yes fall is among us and winter not far behind. After such a big winter on the East Coast last year and wet summer we can only hope precipitation will stay down. Love the stats with the raw data... bookmarked.
