Looking down into the Sea this morning I can see that there has been some cloudiness in the northern end of the Sea from that low that is currently spiraling over Nevada and Arizona this morning. It looks like that will continue for at least until late tomorrow.
For the rest of the Sea a 90 mph jet stream has developed and is picking up moisture along the ITCZ/Monsoon trough and transporting it toward the Baja peninsula this morning. The leading edge of the plume was just off the west coast at sunrise and it would appear that the Sea will be seeing a late season Pineapple Express today. Looking outside I can see the first bands of whispys passing over.
Looking south to the west coast of Mexico I can’t see a cloud anywhere until you get to around Guatemala this morning.
Looking out in the Eastern Pacific basin and the ITCZ/Monsoon trough I can see that thunderbumper activity has picked up a bit between 125 and 135 west and that is where the jet stream is passing over this morning.
Back on the mainland the Tehuantepec is again quiet this morning and the forecast if for very light winds for the 3-day forecast period.
That’s what is going on in our hood. Looking now north to the west coast of America of America where that low that brought showers from the upper Sacramento Valley to San Diego for the past two days is very very slowly moving east and is now centered over southwest Nevada. It will continue to bring unsettled weather to northern and southern California through tomorrow. The higher elevation of the Sierras will continue to see some rain and light dustings of snow at the higher elevations.
In southern California today it will remain cool and the chance of afternoon and evening showers or thunderbumper will continue into tomorrow.
Friday high pressure off the west coast will move ashore replacing the low bringing clear skies and warming temperatures over the weekend.
Looking now over to the southwest where that low pressure system will prevail over the desert southwest into the weekend. There is a chance of mainly afternoon and evening showers and thunderbumpers especially east of Tucson through Sunday. They can expect cooler than normal daytime temperatures through Friday. With the passing of this low a strong warming trend will occur early next week.
Well, that’s what is going on to the north of us. Back on this side of the fence with the exception of the outside passage which will be seeing 20 plus knot of winds over the 3-day forecast period we should be seeing very pleasant May weather in our hood.
The northern Sea will continue to see moderate southerlies today then the entire Sea will be seeing moderate northerlies over the 3-day forecast period.
Here are the wind details for the 3-day forecast period.
The northern Sea: very moderate southerlies today then very moderate northerlies over the next 3 days.
The central Sea: In general moderate northerlies for the 3-day forecast period. Pt Concepción is forecast to have NE winds in the high teens for today and tomorrow but the rest of the central Sea the low to mid teens.
The southern Sea: The San Lorenzo channel, La Paz and the nearby islands light NW today. Mid teens tomorrow and then light again on Friday.
The East Cape: Light today, moderate tomorrow and light again on Friday all from the WNW.
The Sonoran passage: moderate NW winds for the next 3 days with the exception of Mazatlan which will see 18-22 knot winds over the 3-day forecast period, perhaps a bit less on Friday.
The Mexican Riviera: With the exception of Mazatlan which I just mentioned moderate NW winds to Cabo Corrienties and then south of Cabo Corrienties moderate WSW for the next 3 days.
Temperature-wise the over night lows have been dropping about a degree a day for the past 4 days. The daytime highs have also dipped a few degrees. Today the highs in the central Sea will be in the low to mid 80s. La Paz will be the only location to come close to 90 today.

73s Y’all
