.DISCUSSION...
After some patchy smoke/fog early this morning that may reduce
visibility below a mile at times, skies will become mostly clear
with dry weather prevailing through the morning hours. An isolated
storm will be possible this afternoon and early evening, with
cloud to ground lightning the main threat. Winds will be light and
variable early this morning, before becoming east/southeasterly
around 10 mph by the early afternoon with the onset of the
Atlantic sea breeze. Timing of the sea breeze remains difficult,
but is expected to generally occur in the early afternoon
timeframe, and those working on the fire should be aware of a
sudden shift in wind speed and direction around this time.
Relative humidity will drop to 45-50 percent this afternoon, along
with poor to fair dispersion. It will be hot, with high
temperatures in the lower 90s and heat indices approaching 100
degrees.
