They happen in the fall, winter and early spring, so chances are very good. Where I live, though they're cold, but I live closer to the mountains (therefore snow) than DL is, so for me, if there's any snow on the mountains or in the passes the winds are quite cold. I guess they warm up by the time they reach the DL area. But please don't hope for them--they're my least favorite weather condition and make me cranky and edgy.
