Comment From Mike Leuthold

Regarding the dirty air post below, Mike says: The dirty air appears to be from dust that was from the coastal plains of Sonora.  Animating the 1km vis imagery with the brightness turned up, I can just see some dust being kicked up yesterday afternoon.  The WRF was forecasting 25 kt winds in the area due to the gulf surge yesterday and an observation from Hermosillo had a gust to 29 mph.  There are some fires burning in the Sierra farther south and the smoke wasn't moving much. 

The WRF image is forecast winds and speeds from yesterday's 6Z run valid 20Z yesterday.
