.DISCUSSION...
Expect a damp early day with some patchy light fog. Winds and mixing
heights will be slow to increase this morning, but by the noon hour
you should find smoke dispersion transitioning through fair and good.
Increasing near surface moisture will leave minimum humidity fairly
high today, likely no less than 45 percent. A chance for scattered
thunderstorms will begin later this evening and continue overnight,
potentially producing locally heavy rainfall.
