Surface Theta Plot for 2200 UTC 18 May 2011


The above is from the Albany SUNY weather page and shows surface theta (in degrees C) over the Southwest. Note the distinct cT air mass over much of New Mexico and west Texas. This continental air is being pulled into the deep surface cyclone over southeast Colorado. The theta plot also nicely indicates the Pacific front from southwest Colorado across western New Mexico to southeast Arizona.
