Feb. 21 - A break in the winds today. Our minimum temperature at NMSU this morning was 41F and we had a high of 66F. By this afternoon we should be seeing light southwesterly winds with the exception of the Bootheel region. See the RUC 21 UTC forecast below.

 

I've been experimenting with the Real-Time Mesoscale Analysis (RTMA) product and comparing with the RUC forecasts. RTMA is provided in 5-km while the RUC is 20-km. Below is the RTMA surface wind speed analysis for the same time as the RUC plot above. Overall the RUC predictions in our region are close to the RTMA. In the second plot I rescaled the wind vectors so that they were not too crowded.

 

We saw a "mild" low wind high PM event in Sunland Park tonight

 

at the Sunland Park Desert View and

as well as at the Anthony station.
