¡Buenos dias! Yesterday was a great example of the sensitivity of our local thermal to cloud cover, as we got an unexpected partial thermal bump especially at southern beaches where the campground showed 10 minute average wind speeds of 13-16 mph from around 1:30 pm until 5 pm. Satellite imagery showed a very fortunate localized clearing trend yesterday morning…lasting into the early afternoon over the plains (see image below), and that was just enough. Infrared satellite loops early this morning indicated the last of the cloud cover was moving off to the east, and with surface high pressure forecast to build into the central Baja Peninsula today, model forecasts are in excellent agreement that north flow will increase from its anemic levels of late. Unfortunately the wind party will be a short one, as model forecasts continue to indicate light winds returning on Friday as surface low pressure approaches the northern Baja Peninsula. The low will move slowly eastward on Saturday, with light winds continuing over BCS. Models continue to be in good agreement that Pacific high pressure will build into our region on Sunday, with north flow again increasing. Surface high pressure will then begin building into the interior of the western U.S. on Monday, and as this happens, the surface pressure gradient over BCS will tighten further, with norte conditions possible. Long-range model forecasts are in very good agreement that surface high pressure will remain in place to our north through at least Friday, with solid north background flow continuing.
