.DISCUSSION...

Breezy northwesterly surface and transport winds at ignition time
will continue to strengthen this morning, with speeds then
gradually diminishing late this afternoon. These strong
northwesterly winds will create good daytime dispersion values
throughout the day. A dry air mass will remain in place across
our area through the weekend, with long durations of humidity
values around 30 percent forecast throughout the afternoon hours
today and around 40 percent on Saturday. Northwesterly transport
winds will mostly remain in the 10-15 mph range tonight and
Saturday, with surface winds shifting slightly to
west-northwesterly while diminishing to the 5-10 mph range.
These lighter winds on Saturday, along with lower mixing heights,
will result in fair daytime dispersion values at the burn site.
