.DISCUSSION...
Good afternoon. Continued dry conditions are expected across north
Georgia today and through the weekend. RH at the burn site will be
around 33 percent at 11 AM, dropping below 25 percent between 1 and
2 PM. Minimum RH values are forecast to be 20 percent in the mid to
late afternoon. 20 ft winds from NW at 3 mph will shift to W at 5-6
mph by noon and increase to 7-9 mph by 2 PM and through the
remainder of the afternoon. Occasional gusts up to 18 mph will be
possible this afternoon, as well. Transport winds are currently NW
at 7 mph, and will shift to W at 10-14 mph this afternoon. These
winds, combined with mixing heights topping out just above 5000 ft,
will lead to good smoke dispersal this afternoon. Clear skies will
persist through the overnight hours, and maximum RH values will
remain under 65 percent. This will prevent any fog formation over
the burn site. Winds overnight will shift to S at around 5 mph
before becoming light and variable in the early morning.
A dry cold front will sweep across the area early on Saturday. RH
values will drop to near 25 percent once again during the afternoon.
NW winds will increase after frontal passage, with 20 ft winds of 10-
15 mph and gusts of 25-30 mph in the afternoon. Because of these RH
values, winds, and very dry fuels, a Fire Weather Watch will likely
be coming in the afternoon forecast update, which could be upgraded
to a Red Flag Warning in subsequent updates. Please feel free to
contact us if you have any further questions or concerns.
