Areas affected...central/northern Louisiana...southern
Arkansas...western Mississippi
Concerning...Severe potential...Watch unlikely
Valid 121827Z - 122030Z
Probability of Watch Issuance...20 percent
SUMMARY...Marginal severe threat to continue through the afternoon.
DISCUSSION...Thunderstorm activity continues near an MCV across
eastern TX into portion so LA/AR. Largely, this has remained below
severe limits. Echo tops have increased over the last hour or so
with daytime heating and increasing instability across southern LA.
Overall, flow remains weak except in association with the MCV where
around 20-30 kts of deep layer shear are noted on the eastern
periphery. Some organization may occur with deeper updrafts with
potential for damaging wind and perhaps a tornado. This corridor
will shift north and eastward into AR through time this afternoon.
Overall, this risk will likely remain too localized for watch
issuance.

The fire danger meter is for Placerville, California, which is the location of El Dorado Weather. The meter uses the Composite Burn Index or CBI. Listed within the meter is the current temperature and humidity for Placerville, two very important factors in measuring the fire danger. Also shown for the Placerville area is the Sierra Fire Forecast Text.
The rest of the page items are National fire watching tools. This includes the Fire Advisory Map, Fire Detection Map, Forest Fire Causes, and the US Fire Detection Text.
The fire dectection text lists the state, county, nearest town to the fire, and the distance in miles from the town to the fire.
The fire advisory map list the current fire danger or fire conditions severity for the lower 48 states, and shows color coded fire severity for all the national locations.
The Fire Detection Map shows all the current wild fire detections in the United States. Also listed is the exact longitude and latitude for each fire location, the nearby towns, the type of land cover such as deciduous broadleaf forest, mixed forest, or grasslands etc for example.
The pie graph is pretty self explaintory as it stands, and demonstrates a comprehensive chart of all of the causes of forest fires.
