Service.
.DISCUSSION...
Quiet conditions for the duration of the forecast. Steady NW wind is expected
on Thursday, but may become variable overnight Thursday night. Clouds will also
increase after midnight Thursday night.
Reasonably good mixing is expected Thursday afternoon, but not enough for really
erratic fire behavior, as there should be a lingering weak inversion aloft to
hold deeper mixing in check. Transport winds will be out of the NW but will become
increasingly variable into the late evening and Thursday night.
Friday will be less favorable, with precipitation expected to start as early as late
morning, as sleet or snow. Winds will be light through much of the day, and if they
do manage to pick up later on in the day, it almost certainly won`t be until after
there`s steady precipitation falling.
