Just a point about precision, Google Maps fire overlay is based on NASA Firms + some processing, and it's not perfectly accurate.

It is currently marking my little town as under fire / burned down, but it's not and hasn't been so far. (north west front of the fire, next to the lake). It looks like their contouring algorithm is very greedy and any hot spot marked in the past few days has become part of their fire perimeter.

The massive fire clouds probably contribute to the difficulty of measuring ground temperature from satellite.
