.DISCUSSION...
Drier air will make a return and remain entrenched across the CWA
at least through mid-week as ridging builds. The lowest RH values
will primarily be across the western counties. However, winds
look to remain fairly light during this period, at least for areas
that will experience the lowest RH values due to a weak pressure
gradient that sets up across the CWA. This should keep Red Flag
Warnings at bay this week, but a few days will still have elevated
concerns. Expect a change in the weather pattern by late week
into the weekend with a return of cooler temperatures and
increased moisture, limiting the fire weather concerns.
