¡Buenos dias! There were no scatterometer satellite passes last evening over BCS, but all of the latest model forecasts show the background flow decreasing substantially today. A deep trough of low pressure in the middle levels of the atmosphere was located just off the southern California coast this morning, and this feature will trigger the formation of a weak surface low over the southwesten U.S. today, with north background flow over our region falling below the threshold for fully triggering our local wind machine. Infrared satellilte loops this morning showed substantial high clouds streaming in from the southwest, and although we may see some thin spots in the cloud cover at times, the clouds will likely partially dampen our local thermal as well. The bottom line for today is that it looks marginal at best. The vigorous mid-level trough is forecast to move slowly eastward on Friday, with light background flow continuing here and substantial cloud cover likely. The trough will move across the Baja Peninsula on Saturday and models are in good agreement that we will see widespread showers over BCS with rainfall accumulation forecasts ranging from 0.25 inches to 1 inch here. As the storm system continues eastward on Sunday it will likely produce a crippling ice storm across portions of the mid south of the U.S., with heavy snow farther north into cities like Washington D.C. and New York. Back in Baja…surface high pressure will rapidly build in bringing a return of sunny skies and ample north background flow on Sunday. Model forecasts are in good agreement that solid north flow will continue well into next week.
