high winds in Palm Spring

I'm a low timer (110 hours) scheduled to fly from Palo Alto to the
Bermuda Dunes in the Palm Springs area Thursday afternoon.
Unfortunately, I see there is Wind Advisory in effect from 11 am
Wednesday to 9 PM PDT Thursday and forecast winds of 20 to 30 mph from
the northwest. It'd be one thing if that just means strong but steady
winds blowing down the runway. But I'm concerned that it could mean
strong gusts at ground level and/or significant turbulence in the
Cajon and Banning passes that I'll be traveling through. I will
continue to monitor conditions and talk to a briefer prior to making a
go/no go decision but I was wondering if anyone here has local
knowledge about the ramifications of this forecast.

Thanks.
