Record October
02 Nov 2009 04:06 AM
The big story for October was the record breaking amount of rainfall observed for the month. The featured image is an IEM estimated rainfall percentile showing most of Northern Iowa at 100, which means the highest amount on record. Thankfully, November is starting off mostly dry with only a few light showers expected this week.

Staying above the trend line
03 Nov 2009 06:10 AM
The featured chart is a comparison of the accumulated rainfall for this year and last along with the climatological accumulation. In general, the running total for this year has remained above the climatology with the heavy rainfall in October pushing us well north of average again. We are still a ways from repeating 2008, which is a good thing.

Avoiding Flooding
04 Nov 2009 06:45 AM
The featured chart is a time series from the Squaw Creek river gauge in Ames for this year. Unlike 2008, Ames has avoiding any major flooding with only a few events of at bank full. The recent heavy rain last week caused the river to rise, but nothing significant for Ames.

Woefully short
06 Nov 2009 06:37 AM
Outside of a warm week or two this growing season, there was not much heat to speak of and our growing degree total was some 400 units short of average. The record cold in July really hurt as it should be the month where we accumulate the most GDDs. A very wet October did not help the still standing crops any as mold is now a major problem with the corn and soybean crops.
