Chris, like William T. I would also recommend Weather
Underground. If you use it however, be aware it doesn't always
have this info (sky condition or sky cover). For example, see
the same day's data (12-25-10) for Norcross GA, where my group
in GA has had a number of sightings from in the last 2 years:

http://tinyurl.com/22p4sv3

Scrolling down to the tabulated data, you'll see no entries
under "clouds."

When I was looking into Norcross sightings, I used this station
becaue it was closest to the actual sighting location. For one
of them, the presence or absence of fog was an issue; so I
wanted the station closest to the sighting, Not the closest
airport to the sighting. This is a big advantage for Weather
Underground - they have stations (some automated, just devices
are there) all over the place. In my case, they had an automated
station just 1000 feet north of the location in question.
Weather Underground calls these "personal weather stations"
(PWS) and their ID for the one linked above, is KGANORCR9.

But - as I mentioned, no sky condition data. If that's the case
for your sighting, you'll need to get that info from the nearest
place where it is recorded. So far as I know, it is only
recorded at airports (maybe elsewhere too, but airports for
sure). There, the data are recorded as part of the standard
weather-observations data set called a "METAR." There is an
online repository of archived METARs and other met reports, at:

http://www.ogimet.com

click "English version" at top left.

Near the top, you'll see "METAR and TAF queries." Click there,
then all you need do is enter the airport's ICAO code (a 4-digit
code, such as "KPDK"), and the Universal Time (aka Zulu Time)
period that encompasses the sighting time (you must convert
local sighting time to Zulu time, based on time zone). OGIMET
does have a ICAO code-finder search-box there, too, although you
will need the airport's common name.

If the airport does happen to be your closest station, Weather
Underground does give the METARs for the archived days, so in
that case it's easy and you can skip OGIMET or similar archives.
They (Underground) have a handy "METAR FAQ" also, so you might
want to check that out, since the METARs describe cloud cover as
BKN, OVC etc. (broken, overcast), which have defined meanings in
eighths of sky covered.

Hope this is useful to you.
