May 20

Another mild day in the southwest. Sunny with high in Las Cruces of 88 F, and 89 in Deming. Nice clear MODIS Aqua image here.

Similar to yesterday, afternoon MODIS AOD were higher than morning estimates. Higher AOD over west central NM in the afternoon maybe from prescribed burning. According to the SWCC website, there is a prescribed fire in the Black Range from 5/20 to 5/25, burning up to 4000 acres per day.

Storm system coming in this weekend bringing in windy conditions. The bigger story is up north in the Four Corners and into NE Arizona. Calling for another dust storm event with strong southwest winds. Below is NAM-12km prediction for 10-meter wind speed tomorrow afternoon (0:00 UTC). Darkest red is 30 mph.

A different story for the Four Corners. Same model but contour range changed to max of 40 mph. So the dust sources are probably going to blowing lots of dust again tomorrow afternoon and a repeat for the weekend.
