The quality controlled NWS COOP data for June 2009 has been uploaded to the IEM. Harry Hillaker, our state climatologist, passes along these notes for the month:
The month averaged 69.0 degrees or 0.8 degrees below normal. Precipitation totaled 5.27 inches or 0.63 inches above normal. This ranked as the 54th coolest and 50th wettest June among 137 years of records.
Here is a listing of new daily records set for the month based on data back to 1951.

Additionally, I will be including a monthly report going forward providing simple summary statistics on how the IEM's estimate of this month's data compared with the finalized and hand QC'd data. You can check out this news item for more details on the IEM's estimator. These QC'd observations completely replace the estimated values in the archive.
