DISCUSSION: It's no surprise that any forecast regarding precipitation in California has become increasingly viewed. California again is finally breaking the barrier with another day of expected precipitation amid its much televised drought.
This morning, California is expecting precipitation brought by a cold front sweeping through upper/central portions of the state. As the front makes its way through Northern California it will bring widespread showers with increased chances of an isolated thunderstorm. This front is associated with a mid-upper level low,which had been questionable nearly 10 days ago according to models but as the days grew closer, the consensus on location and strength proved correct.
With the frontal passage. there will likely be lingering showers, but we should expect to see a drier evening into Halloween. Northern California won't go entirely without some chances of precipitation into Halloween as the low moves further inland. Temperatures are expected to be within normal mid to upper 60's, with a swift southwest breeze gusting to 30 mph. Precipitation totals are not expected to be significant within the next day or so with totals at 1/4 to 1/2 inch in locations, possibly more in the Santa Cruz Mountains and Northern Bay area.
