.DISCUSSION...
A strong ridge of high pressure will continue building across the
area through Wednesday. Expect elevated fire concerns with high
temperatures around 100 degrees and minimum humidity as low as 10
percent, creating a significant moisture deficit. A limiting
factor during the mid-day through afternoon hours will be wind
speeds generally less than 15 mph, however any isolated thunderstorms
(5-20% chance) that collapse into this environment could lead to
sudden gusty or near-severe downdraft wind gusts that could start
or fan on-going fires. A cold front Thursday morning will bring
cooler temperatures through Friday. Another ridge will raise
temperatures again over the weekend followed by another cool down
on Monday.
