The winter in the Southern Hemisphere was a bad one and this one may have some surprises up its sleeve.

Ain Sefra Algeria elevation [3547']  is at 32°45N latitude. San Diego is 32°.71N; snowfall can drop below 3000'. This weekend/ early next week could produce measurable snow down to 3500' and perhaps lower as Arctic air descends southward.

I suppose that its a bit more notable given the different geographical set up. Most important is that the average elevation in this region of the Sahara is probably higher which means that it can be heated from below, which does not happen for air approaching san diego at 3000 feet. The Atlantic is warmer than the Pacific for these locations as well.

Either way it does happen from time to time, but is cool to see regardless.

Koppen Csa/ Bwh [Mediterranean/ hot desert] for both locations.  Dallas/ Atlanta also 32° parallel north but entirely free of mountain obstacles.
