What a storm, it has over-delivered with impressive totals, more will be added today. In the Pacific Northwest, where all of this started, lingering snow showers will continue through Thursday. Not much for the northern Cascades, a few inches today and tomorrow, but Timberline and Mt Bachelor will add 4-8 today and a couple/three tomorrow.
Tahoe refires tomorrow with a Pacific storm that will bring 8-12, for some spots beginning tonight, through Friday morning. This is another sign of the switch in patterns. You can see the flow has changed in the North American Model above.
In Utah, snow continues today with another 3-5, to top off, before the storm moves out. Colorado will have snow showers today, mainly along the divide, with another 3-5 as well.
I am sorry for the poor quality of the blog the last couple of days, I have been in a remote area with poor internet access and had to resort to posting on my phone, which is very difficult. I was able to do a lot of work on upcoming pattern storms though, to finish out the year.
This Cycle is starting off with a bang, putting up the best numbers, for this storm, through all cycles. So, if that is any indication….
Above is the GFS model through roughly the 24th. I posted this model because you can see the next few systems coming up that I discus below. Next is the U-Storm then the Trifecta, both are showing up. After those storms, the GFS is a little murky.
In the Pacific Northwest, lingering snow showers will continue through Thursday. Temperatures in the mid 20’s with light winds 5-10 mph. For the northern Cascades, 1-3 inches today and tomorrow, but Timberline and Mt Bachelor will add 4-8 today and a couple/three tomorrow.
Pacific moisture arrives after midnight tonight bringing 4-8 for areas along the crest–Sugar Bowl, Palisades and Kirkwood. Snow levels will be around 7000 ft Friday night dropping to around 6000 ft by morning. Thursday will be windy with 30 mph gusts at lake level, with gusts topping 50 at the summit. It will snow throughout the day adding 2-6 and another 2-4 Thursday night before exiting early Friday morning.
Snow today with high temperatures in the low 20’s. Wind will be in the negative numbers, as low as -10, due to wind speeds between 15-20, with 25 mph gusts. Expect another 2-4 today with the storm exiting tonight. The Pacific moisture from Tahoe will swing by Thursday night with light totals 1-3.
Expect a few more inches this morning and afternoon for areas along I-70, with higher totals along the divide. High temperatures today will be in the lower 20’s with moderate winds 10-15 mph.
There will be much higher winds for Arapahoe Basin and Loveland as the storm moves by. Expect up to 50 mph gusts with snow totals in the 2-4 range today with another 1-3 tonight, possibly more with the help of upslope orographic lift.
