Gusty East Winds Again

Very nice sunrise this morning.

Wasn't paying attention yesterday and didn't see that 12 UTC WRF-GFS on the 11th was forecasting another period of strong easterly winds. Forecast above is from 06 UTC WRF-GFS and is for 10-m winds at 11:00 am MST this morning - yesterday morning's forecast was quite similar.

Below is forecast sounding for Sonoita  from 06 UTC today and valid at 11:00 am. - it is an excellent set-up for more strong gusts at the Mt. Hopkins RAWS station with gusts well above 50 mph possible. Bottom graphic shows winds and gusts so far this morning at that site. Peak gusts at this site for last six days have been: 78, 73, 60, 45, 20, and 55 mph.
