.DISCUSSION...
Humidity is expected to remain around 20% for the next couple
hours before beginning a slow improvement the rest of this
evening. Expect a meager recovery to 65-70% while temperatures
bottom out in the mid 70s tonight. Southeasterly winds around 10
mph with occasional gusts to 15-20 mph are expected to continue
before becoming light in speed during the early morning hours on
Tuesday. There may be some temporary wind shifts to the SW during
the 9-11AM timeframe, but wind direction will eventually out of
the S-SE for the rest of the day. Expect speeds 5-10 mph, with
slightly lower gusts up to around 15 mph in the afternoon. High
temperatures are expected to peak around 101 while humidity
plummets to around 30% underneath mostly sunny skies.

While it will most likely remain dry, we cannot rule out a very
low chance (<20%) that an isolated shower or storm develops in the
late afternoon, mainly between 3-8PM. At this time, most of any
activity will likely remain to the east and southeast of the fire
location. If a shower or storm were to develop, lightning and
gusty, erratic downburst winds would be the main threat. Even if
not directly impacted by storms, any outflow winds from nearby
storms that move over the fire may result in erratic wind shifts.
Any development will dissipate as the sun sets, with no additional
rain expected the rest of Tuesday. Better moisture recovery back
to 80-85% is expected Tuesday night alongside low temperatures in
the mid 70s.
