.DISCUSSION...
Southerly 5-10 mph winds will continue this afternoon under mostly
sunny skies with temperatures in the mid to upper 60s to support
minimum relative humidity values around 30 percent. Normal fuel
moisture conditions combined with these weak winds and adequate
humidity values should keep fire weather concerns low today. Similar
conditions are expected tomorrow as warmer temperatures in the mid
70s will be offset by a slight increase in Gulf moisture ahead of
another cold front that will move through late tomorrow afternoon.
Winds will be more southwesterly with a few stronger gusts tomorrow
before becoming more northerly around sunset.
