.DISCUSSION...
Fire weather concerns will remain minimal for the next several
days due to plentiful moisture, high humidity, and occasional
chances for showers. Expect good to excellent RH recoveries each
night through Thursday morning with daytime min RH remaining
well above critical. While humidity will be high, most areas have
a relatively low chance for wetting rainfall due to the spotty
nature of the expected precipitation. A few showers, particularly
this afternoon and evening, may produce locally heavy rainfall.
Warmer and drier weather will work back into the area Friday into
early next week which may lead to locally elevated conditions with
increased breeziness Friday and Saturday.
