Discussion - Wednesday & Thursday

Wednesday will be a bit of a transition day as we shift from the warm and dry conditions to the beginning of a prolonged cool, wet and mostly cloudy pattern.  Gusty southerly winds ahead of the first in a series of Pacific storms will be observed across the N state.  Both surface and transport winds with gusts of 20 to 30 mph but much higher gusts will be observed along higher elevations and across the N tier of the state.  Gusty west and southwest winds can be expected across the southern Sac Vly and Greater Bay Area.  Light showers may occur Wed afternoon but the main band of rain will hold off until Wed night and Thu.  The strong southerlies will continue on Thursday and be especially strong along elevations above 2500 ft. This huge clean out event will bring excellent air quality to the entire region.
