...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.
