Things are starting to warm up a bit as the area of low pressure that helped cool us off and bring showers and thunderstorms in the mountains earlier this week is now heading to the coast of Southern California. As that low tracks to the south and east there will be another trough of low pressure approaching from the Pacific Ocean but it looks like the bulk of any rain associated with it will be in the Pacific Northwest just clipping Northern California on Friday and Saturday. Places along the coast and to the north in Northern Trinity and Siskiyou Counties may see a few light showers but we’re not expecting much in the way of rain. The main impact for most of us will be cooler temperatures and added clouds on Friday and Saturday.
The trough will move to our north and east by Sunday and a zonal flow pattern (fast flow of the jet stream from west to east) will set itself up allowing us to warm back up to the upper 70’s and low 80’s. A few weak disturbances are expected to move through the upper level flow but it will be mostly in the form of clouds.
High pressure will briefly build back over the Northstate in the middle of next week which will allow our temperatures to climb back up to the mid 80’s under sunny skies.
