Spot Forecast for Half-A-Canoe RX...CAL FIRE

National Weather Service San Francisco CA

702 AM PDT Wed Jul 2 2025



Forecast is based on ignition time of 0700 PDT on July 02. 

If conditions become unrepresentative, contact the National Weather

Service.



.DISCUSSION...Fairly quiet today, with the marine layer not as 

prevalent around Lake Sonoma this morning. Satellite does show the 

burn site on the edge of the stratus, with clouds continuing to 

erode. Expect mostly sunny skies within the next few hours and then

winds gradually shifting to the southwest and west by the afternoon.

A few gusts up to 15 mph may be possible during this time and minRH

values falling to around 30-38 percent. Tonight, the marine layer 

should re establish around 1200 to 15000 feet, similar to what we 

saw this morning. This should bring partly cloudy skies to the burn

and RH recovery to around 75-85 percent. The RH values could be at

play here in two scenarios. Should we get more of a stratus surge,

we could be closer to 80-95 percent, but should the stratus stay at

bay we could be a bit lower and closer to 55-65 percent which has 

been observed at higher elevations. Thursday, another dry day is

expected; however, there will be a good onshore push of winds. Look

for these to be 15 to 25 mph with gusts up to 30 mph possible.
