...MAJOR PATTERN CHANGE APPROACHING WITH SIGNIFICANT MONSOON
MOISTURE ARRIVING BY MONDAY AND INTENSIFYING TUESDAY...

.DISCUSSION...
Increasing cloud cover today will be the first sign of a
significant moisture increase across the fire. There is a small
chance for a thunderstorm to impact the fire or nearby between
3 PM this afternoon and around 8 PM this evening. It is important
to note that there is not a lot of agreement with the model
solutions today, and most of the models keep the thunderstorm
threat south. The increasing cloud cover will also help knock
down instability somewhat for this afternoon. There is a little
bit better chance to see a stray very light shower or virga
this evening, overnight, and into early morning Monday before
the moisture trends really ramp up. If a thunderstorm or
virga shower CAN develop today, the main threat will be for
erratic wind gusts 35 to 40 mph. Beginning Monday afternoon,
humidity and potential rainfall chances increase significantly.
