Relative humidities today will reach their lowest of the week,
and region-wide gusts will reach over 25 mph as well. While
today will be the most prolific fire weather day, the rest of
the week will be dry and windy as well. Red Flag Warnings are
in effect today while the Fire Weather Watches for Tuesday have
been upgraded to Red Flag Warnings. Confidence is increasing
for more fire weather highlights on Wednesday though coverage
will likely start decreasing as surface winds lighten up.
