.DISCUSSION...Today will be a few degrees warmer with lower RH
compared to yesterday, but winds will be similar to yesterday--at least until
late afternoon. A dry cold front will gradually travel across eastern Washington
on Sunday. Winds will increase tonight ahead of the front and will
continue to increase on Sunday. The frontal passage over the burn site
will be between 1100-1300 PDT on Sunday. Although RHs on Sunday are
forecast to be higher than today, there is a lot of dry air aloft behind
the front.  If the dry air mixes to the surface, there is a chance that RHs
will briefly drop to around 20-25 percent.

Thank you for the observations!  Very helpful!
