Today we observed a fog this morning that dissipated

mostly cloudy and wind is increasing as the pressure
begins to drop. We experienced a max gust of over 30
mph and the average speed is up over 15 mph from the
west.

We measured 0.53 inches of rainfall from the event
that began yesterday evening.

The high so far today is 64F, 25 degrees above the normal
maximum of 39F. The low since midnight is 52F, which is 31
degrees above the normal minimum of 21F. Astonishing!
