Forecast (as of now):
Thursday into Friday, a weak upper level cold front will roll through. It will likely produce clouds, some fog and a chance of showers and thunderstorms. And given the increasing humidity levels til then, I wouldn't be surprised if a few pop up. Temps in the mid to upper 60s and winds peaking 45-60 mph before decreasing to 20-35 mph.
Saturday looks as though high pressure will build back in, but there are two things that should be of some concern: upstream convection and a zonal flow. But as of now, it looks like the high should be holding as sunny, upper 60s, winds 20-35 mph dominate. But the flow and the possible convection will have to be monitored til then.
As for the sunrise drive, that is a bit iffy. There is a weak cold front dropping down on Sunday. The drive will all depend on how fast or slow this front moves down.
I will be providing a limited edition extended higher summits forecast on our webpage starting Thursday morning. So stay tuned for more as it comes about...
