¡Buenos dias! Rainfall totals varied substantially from north to south yesterday, as both the campground and Club Cerralvo gauges measured just over 0.3 inches, while farther north where a couple of heavier showers spilled over the Cacachilas Mountains, the gauges in El Sargento and El Jalito ranged from 0.6-0.8 inches. On a broader scale, gauges across southern BCS showed an overall pattern that matched several model predictions of heavier rain from the mountains westward, and lighter totals across areas along the eastern coast (see graphic below). Infrared satellite loops this morning showed clear skies across BCS, and all of the latest model forecasts show a sunny day ahead. A pass by one of the ASCAT satellites last evening measured west winds of 10-15 knots near Cerralvo, but all of the models show the background flow will become north by this afternoon as surface high pressure begins to build into the interior west of the U.S. As the surface high to our north continues building into the western U.S. on Monday, the surface pressure gradient over BCS will tighten, with north background flow increasing substantially. Models are in excellent agreement that the mid-level blocking pattern we’ve seen for much of this winter season will persist through the upcoming week, with a ridge of high pressure along the west coast of North America and a deep trough of low pressure to the east. This will bring dry weather and above normal temperatures to areas west of the Rockies, with wave after wave of brutally cold arctic air for areas east of the Rockies. For us, we’ll likely see the surface high anchored to our north remain nearly stationary through the upcoming weekend with ample N to NNW background flow each day. The only variable will be high cloud cover which may partially dampen our local thermal each day from Monday through Saturday.
