Monday Jan. 5
The high pressure in place over the West Coast will keep Tahoe dry and unseasonably warm for the first of this week. Toward the end of the week, a series of very weak low pressure systems will try to make their way into Northern California but the forecast models are showing nothing more than clouds and a cooling of afternoon high temperatures. Far Northern California could see some rain and it is possible a stray shower or two will drift as far south as Tahoe, but that does not seem likely, and no significant precipitation is expected through at least the weekend. With the way the dynamics are setting up over the Pacific this week, it’s possible we could be looking at a repeat of last January, with every significant storm getting pushed north and into the Pacific Northwest and Canada before dropping down into the interior of the US. Let’s hope that is not the case. Stay tuned for updates.
Friday Jan. 2
An area of high pressure building off the coast of California will bring increasingly warm temperatures to the Tahoe Basin over the next week.
Highs should warm into the 40s today and through the weekend, then could reach into the 50s by the middle of next week. Skies will be mostly clear.
The extended forecast models show the high pressure holding through at least Wednesday, with some indications that it will begin to move east toward the end of next week.
A low pressure system will be moving from the Pacific onshore around Thursday or Friday but so far the models show it either splitting apart when it hits the coast or getting pushed north into the Pacific northwest and Canada. Neither scenario is very hopeful in terms of precipitation for Tahoe. But if the high pressure does shift that would open the door to any storms to follow.
Wednesday Dec. 31
A cold low pressure system moving away from the Sierra Nevada this morning is still generating some high winds around the region, with gusts of up to 100 mph reported along the crest and gusts of 35 mph to 40 mph below the ridge level. Combined with temperatures in the teens, the wind chill factor around the Tahoe Basin is close to zero in many places. Stay warm!
Those winds should begin to subside this afternoon as the low pulls away from Northern California and moves into the desert southwest. An area of high pressure over the coast, meanwhile, will bring a return to seasonable temperatures, with highs in the 30s and 40s by the weekend.
The high pressure will remain in place through the weekend. There are signs that it might drift eastward by early next week and open the door to more Pacific storms for the Sierra. But it’s too early to say for sure.
Tuesday Dec. 30
A weak low pressure system moving through Northern California and Nevada this morning will bring a dusting of snow to the Tahoe Basin today and high winds this afternoon.
Temperatures will be on the chilly side with highs in the teens or low 20s, and with the wind the wind chill factor will make it feel like single digits at times.
The winds should peak this afternoon and tonight with gusts around 50 mph possible. Behind the front temperatures will be even colder, with lows tonight near zero.
A warming trend should take hold by New Years Day with temperatures in the 30s again.
The next chance for real snow will be next week.
