A shortwave trough moving through the region today with a low

the afternoon as a ridge of high pressure from the Eastern Pacific 

builds into the region.  Scattered showers possible mainly along the 

coast and higher terrain of Nrn and Central CA and over NV into 

tonight. Precip amounts will be variable with the convection but 

amount generally expected to be a tenth of an inch or less with 

local amounts to around 0.25 inches possible. High pressure builds 

into the region from the Eastern Pacific Monday into early Thursday 

bringing warmer and drier conditions. An upper level trough 

approaches the west coast late Thursday into Friday with the low 

moving through CA late Friday into Saturday. This will bring a 

chance of precip mainly to the north late Thursday into early Friday 

then spreading south late Friday.
