...WARM AND GENERALLY DRY INTO MONDAY...

.METEOROLOGICAL CONDITIONS (WED AM - TUE AM)...

High pressure off the west coast and nudging into the region with
northerly flow aloft as trough digs down into Pac NW and Nrn Rockies
from Canada into Thursday. This will bring dry and warm conditions
to the region with temperatures generally near normal to 10 degrees
above normal through Thursday. A weak disturbance (GFS stronger than
EC but not as strong as yesterday 06Z run) moves through Central/Srn
CA and Srn NV on Friday that may bring some instability for cumulus
buildups and possible isolated showers along the Central/Srn Sierra
and Srn NV in the afternoon/early evening. High pressure shifts over
the region for the weekend as a low and cold front approach the Pac
NW/B.C.  Temperatures generally around normal to 15 degrees above
normal except max temps up to 10 degrees below normal along the NW
CA coast on Saturday as the tail end of a cold front swinging into
B.C./Pac NW may brush by far NW CA coast. Ridge may shift to the
east Monday as a disturbance approaches the CA coast (GFS moves
onshore Monday night, EC is slower and stronger than GFS with low
off along Central CA coast Tuesday night). Temperatures may cool a
little Monday especially along the CA coast with onshore flow. Left
the forecast dry for Monday for now.  Mid to late next week looks
like it will be cooler and a chance of precip, especially in the
north.
