High Temperature Profile

05 Feb 2009 06:23 AM
The featured plot is of daily high temperature percentiles from Ames based on data for the past 100 years. The plot provides a colorful look at the climatology of Ames. The black line is the 32°F contour. For February, this contour rapidly decreases, which implies that our chance for having a high temperature above freezing is rapidly increasing. The forecast calls for temperatures above freezing for most of the state and even thunder showers expected next week.

Temperature percentiles

04 Feb 2009 06:19 AM
The featured chart is a time series of daily high and low temperature percentiles. Based on historical temperatures, a percentile quickly shows the percentage of observations above and below the actual value for the day. It is effectively a way to rank the observation. The exceptional cold around 15 January sticks out in this plot with a repeat period toward the end of the month.
