Jan. 28 -

A cold front dropped temperatures a few degrees but an upper level ridge will build up over the next few days to warm us up. Even with the colder air mass over us our low was still above average. Below is this morning's observations at the NMSU NWS Cooperative weather station.
                 Yesterday            Today
Station       High(F) Normal    Low(F)  Normal  Record Low Precip
NMSU            68      61       35      29       15 (1965) 0.00"

The AQI forecast for Sunday is showing an area of moderate air quality over the eastern border region. According to the airnow page, it is due to ozone in Dona Ana county and PM2.5 in El Paso.  Today peak hourly ozone was in the 35 ppb range in Las Cruces and Sunland Park. I would expect PM2.5 to creep up tomorrow a little more than ozone with low winds in the 8 mph range
Elsewhere in the nation there are really cold spots.  Mark Albright at the University of Washington reports that  the Jim River DOT station near Prospect Creek Alaska reported a -77F low temperature on Saturday morning. Prospect Creek, AK, holds the record for coldest temperature in the United States at -80F on 23 January 1971.
