We have one more day to dry out before a series of moderate storms return to the region. Clouds will increase Wednesday with temperatures warming to near 60 degrees in the valleys. The next storm system, a weak to moderate atmospheric river will follow on Thursday bringing valley rain and mountain snow and rain (snow levels will start near pass level in the morning and then lower to near lake level by the late afternoon.)

A second colder system comes through Friday. Although the brunt of that storm will likely focus south of the Lake Tahoe area, it will probably be strong enough to bring valley rain and mountain snow to our latitude. Scattered showers continue through the weekend, and another strong to moderate storm arrives for the start of next week.

Margaret Fish of Reno (whose uncle, Henry T. Harrison, was the meteorologist on Admiral Byrd’s first expedition to the South Pole back in 1928-30) wrote me some time ago and included a quote from a meteorologist in Maine who says that the appearance of jet contrails could be a signal of an oncoming storm. She wondered if that was something that only worked back east, or did it work here too? I’ll continue this tomorrow.
