While there is a 10% chance for an isolated rain shower in the fire area through 1900 CT this evening, no rainfall is largely forecast through this weekend. Northwest winds this evening become light at or under 5 mph Saturday even as minimum relative humidity drops down to about 30% Saturday afternoon and evening. Near-critical fire weather conditions for the dry RHs are not currently expected, but a future Special Weather Statement for those dry conditions Saturday afternoon cannot be entirely ruled out in the future. Expect calm winds Saturday evening to shift southeasterly and increase in speed towards 8-10 mph Saturday late evening into the overnight hours. Breezy southeast winds, hot temperatures in the upper-80s and dry relative humidity again around 29% Sunday afternoon prompted the Fire Weather Watch for Sunday afternoon and evening. A wetting rainfall is next expected at the fire site Monday. .TONIGHT... Sky/weather.........Mostly clear (10-20 percent). Chance of pcpn......0 percent. Min temperature.....Around 51.
