.SHORT TERM... (Today and tonight) Issued at 1215am PST Monday Jan 13 2025

Believe it or not, the pattern is changing tonight. A short wave trough at 500 mb is moving through the Bay Area, bringing a patch of mid to high level clouds. Over the next 24 hours, this feature will continue to dive south, and become cut-off roughly 500 miles west of northern Baja. At the same time, a ridge from the Eastern Pacific subtropical high will slide over the top, towards the Pacific Northwest. This will create a situation with high pressure directly north of low pressure, or a Rex Block.

With lighter winds, the temperatures are dropping more efficiently tonight. The mid to high level clouds will put a damper on the cooling, but only briefly. The Satellite loop shows we will only be dealing with these clouds for a couple hours before the clear skies return.

This pattern will also support another round of strong offshore winds through Tuesday, but not quite as widespread or as strong as the recent wind advisory. Winds will calm by mid-week as the cut- off low gradually fills in the absences of any upper level support.

Long Term
(Tuesday through Sunday) Issued at 1215am PST Monday Jan 13 2025

The new Rex Block pattern will live up to its name, keeping the weather consistent through the week. The skies will stay mostly clear with no chance of rain. Offshore winds will persist through mid- week, with decreasing intensity. The 850 mb temperature will remain between the 50th and 75th percentile for this time of year. The clear skies and dry air mass will enhance radiational cooling at night. Minimum temperatures will range from the mid 30s inland to mid 40s near the coast. Maximum temperatures will be in the low to mid 60s for most.

By Friday, the pattern will begin to break down as the low west of Baja gets reabsorbed into a trough moving through the desert SW. This will allow a return to the Omega Block pattern that we had all of last week. This Omega Block - Rex Block - Omega Block combination is bringing unusually dry weather to what is typically the wettest time of the year. Downtown San Francisco has only recorded 0.19" of precipitation so far in January, when the normal for the first 2 weeks is over 2". The extended guidance and CPC outlooks suggests there is a good chance this next omega block keeps us dry through the following week and possibly all the way to the end of the month.

With the fires in Los Angeles and the prolonged dry spell here, we are starting to take a peek at fuel moisture. The energy release components have responded quickly to this weather, and are well above normal for this time of year. Fortunately, we entered the month in a much better place than southern California, and nearly all zones are still below the 60th percentile for the annual average. The Central Coast zone is the exception, as the ERC has recently crossed the 60th percentile and is expected to reach the 80th over the next week. For the first time in months, the Southern California Geographic Area Coordination Center has placed the Central Coast Zone (coastal Monterey County) in a low risk of significant fire potential starting Sunday and continuing through the end of the forecast (Saturday). The rest of our area remains in the "little to no risk" category this week.
