.DISCUSSION...Elevated, near-critial fire weather conditions will
persist again today due to very dry conditions and breezy
afternoon wind gusts. Similarly to yesterday, there is a VERY
small chance (5 to 10 percent) of an isolated virga shower/storm
near the fire. If a virga shower passes by/near the fire site,
expect gusty, erratic winds of 40-50 mph. Very little change in
the forecast is expected through the first half of the week ahead
with our pattern shifting in the second half of the week to become
a bit cooler with some increasing moisture.
