Another Cool Month

Posted: 01 Oct 2014 05:23 AM

Preliminary September data is in the books and statewide it appears to come in just a bit below average. The featured chart plots the monthly temperature departures along with the monthly El Nino 3.4 Index values. These two variables are often compared, but the impact of the El Nino index on our weather is not considered to be instantaneous (there is some lag for what's happening over the central Pacific Ocean to reach us). You can now generate this chart for a time period of your choice and for other locations in the midwestern US.

Good = 8
Bad = 6
Abstain = 6
