Spring Back to Winter…..
I get the feeling this week that a lot of people are getting out of Winter mode but you may want to hold off on breaking out the shorts for a couple more weeks. We have a series of storms on the way and we will transition back into a colder pattern by the end of this week that could last a while.
We start tonight with a fast moving storm that will bring 3-6 inches above 7000 ft. and 6-9 inches along the crest. At lake level we may get a couple inches after the snow levels drop to lake level. Things should clear out pretty quickly on Monday with sun and a fresh blanket of snow on the mountains.
Next storm is about 36 hours behind this one and ready to move in Tuesday night. This storm is stronger and will bring a decent snowfall to the mountains. Snow levels will start just above lake level again before falling. Looking for 12-18 inches above 7000 ft. and 18-24 inches on the crest. At lake level it will depend on how fast the snow levels fall but 6 or more inches are possible. This storm will last into Wednesday.
The storms over the past couple of weeks have been a little mild. This is due to the location of the ridge up near Alaska leaving the Pacific wide open for storms to come across the middle and pick up warm moisture before hitting the Pacific NW. We have been on the South side (warm side) of the storms where a weak cold front gets dragged through as the storms head East. This storm pattern will change on Thursday.
A ridge will begin to build out around 150w and will expand Northward. This will begin to push the storms up towards Alaska and then dows the West coast. The trough along the West coast will dig deeper and that will bring a return of colder weather by this weekend and into the following week. That means a return to highs in the 30′s even down to lake level.
The first cold storm is arriving on Friday and could move slowly inland over the weekend. Right now next weekend looks like a cold and snowy weekend with some models showing several inches in a snow showery pattern, and others showing several waves of moisture that could bring a couple of feet.
The colder pattern looks to continue into week 2 and beyond as the ridge stays out in the Western Pacific. We should continue to see storms dropping down the West coast into CA. The difference in March is that a cold pattern is highs in the 30′s & 40′s with a stronger sun as compared to the 20′s & 30′s with a weaker sun in previous months. So when it’s not snowing it will still feel pretty nice outside. The cooler temps will aid in keeping the snowpack in place into April. BA
