...Discussion from SFOFWFMTR...





Marine layer and brief warning trend will be the stories for the 

next few days. A very weak area of high pressure will trickle across

the service area Friday and Saturday causing a rise in daytime high

temperatures. Overnight temps will fall into normal ranges under the

marine layer. Areas above the marine layer will remain on the warm

side with weak RH recoveries both Friday and  Saturday nights. The

pattern seems to be setting up tonight to see some light offshore

winds along area ridges in the early AM hours of Friday, with the

strongest winds over the North Bay Interior  Mountains. Gusts are

not expected to exceed 25 mph and remain in the 5 to 10 mph range

elsewhere. This will reinforce the drying expected the next few

days. A cooling trend will return next week.





...Discussion from SFOFWFEKA...



Temperatures are forecast to gradually warm the next several days

with highs pushing into the 100s for many interior valley locations

on Sunday. Relative humidity is not expected to be extremely low,

primarily because moisture will begin to move into the region ahead

of an upper low pressure system. This system will bring an

increasing chance of thunderstorms over the interior Monday and

Tuesday, with the  highest chances of storms in Trinity County.
