Thanks, guys.

Up here, when I watch football and baseball games that are being
broadcast from a southern US city, the one thing that never ceases to
catch my attention is how the people in the stands are just wearing
light windbreakers and autumn jackets in January and February, and how
much shorter the shadows are (meaning the Sun is higher in the sky
there).

I would have never expected there to be snow on the US/Mexico border,
but I fully expect that the mountain areas would have plenty of snow,
even in Mexico (cuz the warm moist air gains altitude as it gets pushed
over the mountains).

One big difference when you get much past middle of KS heading west is
that typically our dewpoints are much lower. Consequently, while it can
be in the low- to mid-teens at night here, it's not at all unusual to
have highs in the 50s/low-60s and occasionally even 70s even during
Dec/Jan/Feb because w/o any significant moisture in the air the heat
capacity is very small and so insolation heating is very effective.
And, of course, the converse is true w/ wide-open clear skies at night
radiation cooling is very effective at cooling it off after sundown.
