.DISCUSSION...
Scattered rain showers are expected to continue through this
afternoon with an isolated/gusty thunderstorm possible. Showers will
diminish by tonight with rain-free conditions Thursday and
Friday.

Low humidity (<30% minRH) is expected in most areas on Thursday
afternoon with a potential minRH floor around 10-15% based on the
low end of the model forecast range. The wind will be light under
the influence of a seasonably strong high pressure system
dropping southward from northern Manitoba Canada. RH values will
drop near or below 30% on Friday once again with winds
occasionally gusting to 20mph. Milder temperatures and increasing
moisture will preclude fire weather concerns this weekend.
