Freezing Dates

The IEM processed "climodat" archive is used to list out the first dates after 1 August that a given site first dipped below 32°F and 28°F. The dates when those events occurred are shown. The second set of columns print out the fall day of the year that the climatology dips below the given threshold.

Only the August through March period is considered for this analysis. There is currently a data processing bug whereby the year of the first dates are not shown for all sites. This will be fixed over the coming days.
