Good morning. A weak frontal boundary will cross through the area
today and west to northwest winds will become breezy, with gusts
to around 25 mph expected through the afternoon hours at the
planned burn location. Good mixing will bring down dry air aloft
down to the surface, and RH will steadily drop, reaching minimum
values of around 30 percent this afternoon. The good mixing and
brisk transport winds will result in excellent smoke dispersion.
