Weather is short term and can get freaky ... while climate is long term (geography and ecology courses) and hopefully doesn't get freaky.A cold front just needs to hit tropical moisture just right to produce a freak desert snow in winter months.... One instance was when I had Thanksgiving leave from Fort Bliss (El Paso on the border). I drove up through northern NM and Colorado with skis and snowshoes trying to find snow unsuccessfully but when returning to the Mexican border, started to get big flakes in las cruces (1/2 hr north of ELP) while the rest of the US had none ....07 or 08. The other question is how long the snow stays around and to what depth?
Another was in a large canvas tent in Kuwait being pummeled by cold rain since it was relatively close to the Persian gulf; in summer, the area was past Phoenix hot. Never been so cold and miserable.. and I've been stationed in Korea and Kansas during winter months!
