.DISCUSSION...

A cold front moved through the area and drier air is already
starting to infiltrate the area. We will likely mix efficiently
this weekend and that will lead to min RH values dropping into
the 30 to mid 40% range. Luckily lackluster winds will be in
place through the period will and this will limit any critical
fire weather conditions.
