Not for sure if this is the one you have in mind. This one is from the Forest Service..Might check:
http://www.fs.fed.us/land/wfas/map_list.htm
and look at the link: Daily Observations
there are also links to Maps & Map Archives, as well as, other links:
Daily Observations, Fire Danger,Daily Forecast, Experimental Products Status and Updates NFDR Fuel Model Map.
Hope it's the one you were thinking of...
Have found the information useful at different times.
