A warm and mostly sunny week ahead. Spring officially starts Saturday night at 9:30 pm, but the last several days of winter will be decidedly spring like. High temperatures in the upper 60s to low 70s through Sunday will give way to a moderate winter storm Sunday night into Monday, which will bring a chance of valley rain and high elevation snow to the mountains, and we will see valley temperatures drop back to the 50s for the first half of next week.

Chuck wondered why eastern Nevada was colder and snowier than the western. In terms of the temperature, it’s mostly due to the fact that by the time you get to the eastern side of the state the airmass has become a little more continental in nature. We still have a little bit of marine influence from the Pacific Ocean here, although it’s not nearly as pronounced as on the western side of the Sierra. A continental airmass tends to be a little colder in the winter due to a little less moisture in the air.

But if the air is drier in the east, why is it snowier? I’ll answer tomorrow.
