.DISCUSSION...

TIM, IT LOOKS LIKE WITH SECONDARY FRONT MOVING THROUGH
TONIGHT...WE WILL BE LOOKING AT NW WINDS THE ENTIRE DAY SATURDAY.
ALTHOUGH THE WINDS BELOW ARE NOT ALL THAT HIGH...THINKING THEY
WILL BE GUSTY WITH VALUES OF 15 TO 20 MPH AT TIMES. IN
ADDITION...RH VALUES ARE GOING TO BE QUITE LOW AS LOW DEWPOINTS
MOVE IN QUICKLY. WOULD NOT BE SURPRISED TO SEE AN HOUR OR TWO OF
RH VALUE SIN THE UPPER TEENS. WE WILL LIKELY BE ISSUING A FIRE
DANGER STATEMENT LATER THIS EVENING OR TONIGHT. DISPERSIONS WILL
RUN HIGH GIVEN THE GUSTY WINDS.
