.DISCUSSION...
Good morning! Conditions continue to look favorable for burning
during this afternoon. RHs will drop into the 40s under mostly
sunny skies today. Winds will NE and light, though could see
things pick up to 4-7 mph for 20ft winds. Transport winds will be
from the NE at 5 mph around ignition, picking up to 13 mph through
the afternoon. This make may for "fair" smoke dispersal
conditions and ADI values that will increase to the 40s. This
evening into tonight, winds will go relatively light, but with
very dry air still around, humidities won`t rise high enough to
create any LVORI/smoke fog concerns.
As always, if you have any concerns or questions, don`t hesitate
to reach out.
