.DISCUSSION...
Main concerns will be thunderstorms producing strong and erratic

lower with increasing relative humidities into Monday. Isolated
showers will be possible (20%) beginning late tonight with an
increasing rain and thunderstorm chance (50%) by Sunday afternoon
and continuing through Sunday night and into Monday. Locally heavy
rainfall is forecast with strong and erratic wind gusts with any
storms. Any bursts of heavy rainfall on the burn scar could enduce
some flash flooding (5% chance) late Sunday into Monday. Outside
of storms, expect overall light and variable winds.
