The view above is looking west toward the Santa Ritas from about the point used in the WRF for the Sonoita sounding. Mt. Wrightson is the highest peak of this sky island at 9452 ft MSL. The very large and deep saddle (Riley Saddle) to the south (left) of Mt. Wrightson is immediately upwind from Mt. Hopkins and provides a large gap that probably accelerates blocked flow. Mt. Hopkins is physically separated from the main massif and principal ridge-line of the Santa Ritas, adding to the complexity of the situation when winds are from the east.
The two forecasts here are for 10-m winds from the 06 UTC WRF runs at Atmo. Above is from the WRF-NAM valid at 10:00 am MST tomorrow morrning, while the WRF-GFS forecast below is valid at 9:00 am. Both forecasts show blocked flow accelerating around the sky islands of southeast Arizona with light winds at the highest elevations, as per Mt. Lemmon and Mt. Wrightson.
The two WRF-GFS forecast soundings for the Sonoita point shown here are valid at 6:00 am (above) and at 7:00 pm (below), both on the 20th (tomorrow). The strong easterlies don't reach above 750 mb, leaving my forecast somewhat uncertain, particularly since I have not looked at many of these situations to date. There is definitely a zone of strong vertical wind shear at the top of the layer of easterlies, and I am not sure what we will find in the RAWS observations for Mt. Hopkins tomorrow
Finally, I looked at the hour-by-hour NWS grid point forecasts for Mt. Hopkins (above) and for TUS (below). Whatever algorithm is used to generate these forecasts (probably driven by the operational GFS) ends up forecasting max wind gusts of 31 mph at both sites, which is probably not very likely - but we will see what tomorrow brings.
