.DISCUSSION...
Partly cloudy and hot conditions will continue today with highs in
the 90s with south winds near 15 mph by midday and after. A few gusts
may exceeded 20 mph at times late morning into early afternoon. Gulf
moisture will continue surging across your area with minimum RH values
only fall to between 45 and 55 percent this afternoon. At ignition time,
humidity values will likely start off between 65 and 70 percent. Can`t
rule out an isolated shower later this afternoon, but for the most part
it will be a precipitation-free day. Mixing heights should rise to near,
or above 5000 ft or near the 850mb level today for good plume evacuation.
