Under the influence of high pressure to our north tonight will be
calm and dry. This will continue into Saturday when RH values are
expected to bottom out around 30 percent, especially for the southern
Cumberland Plateau. No fire weather concerns as winds should remain
between 5 and 10 knots. Moisture will start to pump back into the mid
state ahead of an approaching system on Saturday night. Sunday
through at least Tuesday will be plagued with showers and possibly a
few thunderstorms.
