A high pressure system has been settled over Northern California for well more than a week now, keeping things dry and sunny, according to the National Weather Service in Reno. It is a pattern that should persist until Thanksgiving.The pattern normally takes place at least once or twice during Sierra winters, said National Weather Service meteorologist Brian Brong.

“Having high pressure over us for this long isn’t that unusual,” Brong said.But meteorologists say the high pressure should be pushed to the east after Thanksgiving, opening the area up to the possibility of precipitation by Friday.

“That would allow storms to move onshore rather than be deflected up to the north,” Brong said.Meanwhile highs are forecast to top out around 60 degrees and lows are expected to fall near 15 degrees at night through Thanksgiving. An inversion layer has trapped cold air in the valleys and left the higher elevations warmer over the last couple weeks, said Brong.
