Oct. 20 - We're continuing to warm up after the cold front from a couple of days ago. This morning's low at NMSU was 44 which is right at the long term averge. Yesterday's high was 75, a degree below of the long term average.

The AQI forecast for today again shows the same moderate (yellow area) air quality as yesterday over Dona Ana county.
A fairly strong temperature inversion near the ground should cause pollutant concentrations to be elevated this morning (see bottom of the red curve).
Haze in Las Cruces was a little higher than usual. It's not clear what the cause is considering winds locally are low, humidity is low, and there are no fires in the region.
