* Station receives a "Caution" flag if one of the following instances occurs...

1) Absolute average difference for Temperature (see graph below) rises above 15.
2) Absolute average difference for Pressure (see graph below) rises above 15.
3) Absolute average difference for Dew Point (see graph below) rises above 20.
4) Wind check analysis reveals an overwhelming majority of wind observations have the same values (speed, direction, or gusts) over a 3-day period.

A "Caution" designation does not necessarily mean the data is bad, since there may be local conditions at a site which cause it to vary from its neighbors.
