Significant rain and thunderstorms possible Sunday night into Monday as system moves in and last updated 2020-12-28 03:09:34-05 Sunday was beautiful on the Central Coast with partly cloudy skies and temps in the low 60's, but this is really the calm before the storm. The first significant storm of the season will bring widespread rain and mountain snow to the region this evening through Monday night. WOW take a look at the recorded rain over the last 2 hours in SLO County! We could see up to 1 inch (possibly more at this rate) in some places by Tuesday morning.Posted by Megan Healy TV on Sunday, December 27, 2020
