.DISCUSSION...
A gusty northwest outflow from earlier storms may reach the area
in the immediate future, but confidence becomes very low for
storms in the vicinity and gusty outflow winds beyond the next
couple of hours. Thunderstorm chances decrease through the
weekend, with only a 20-25% chance Saturday afternoon/early
evening and a 10% chance Sunday. Winds will follow diurnal trends
(outside of any thunderstorm influence), with sustained speeds
mostly below 15 mph and occasional afternoon and early evening
gusts to 20 to 25 mph out of the west southwest. Winds will shift
south early morning and veer to west by the afternoon, followed
lighter northeast winds establishing overnight. MinRHs will
generally range from 20-25%, with fair to good overnight
recoveries.

...Thunderstorms imply gusty winds...
