Wind – December 12, 2025

¡Buenos dias! None of the wind-measuring satellites passed over BCS last evening, but all of the latest model forecasts show the near perfect conditions of yesterday will continue for almost another week. There may be a few thin, high clouds at times on Monday, but otherwise look for sunny skies each day, with our local thermal in fine form. The surface high that is locked in place to our north will remain there through Tuesday, then begin to move southward and weaken on Wednesday. At this point the long-range model forecasts are in good agreement that we'll see light winds on Thursday as the surface pressure gradient becomes weak.

Nerd Note: The strong ridge of high pressure parked over much of the western U.S. will continue to bring near record warmth to areas of the Sierras, while to the east, a corresponding deep trough of low pressure will allow more arctic air to plunge into the midwest of the U.S. Below is a graphic showing the forecast wind pattern and speed for Sunday at about 20,000 ft above sea level, and the National Weather Service 7-day forecasts for Kirkwood ski resort (Lake Tahoe) at 9000 ft, and for Chicago.
