Cold February Morning

06 Feb 2015 10:25 AM
Morning low temperatures on Thursday were some of the coldest so far this season with the Ames Airport hitting -22F. The featured chart presents one minute interval temperature data for a few Iowa ASOS sites. It is interesting to note the fluctuations occurring and differences between neighboring sites. The sites report in whole degree Fahrenheit, so that explains some of the jitter in the plot. On mornings like this, low micro-climate affects are strong as small pockets of cold or warmer air pass by the sensor. Once the sun takes a hold, the differences are lessened by 10 AM as the lower atmosphere mixes out small scale differences.
