Gotta Love Powder in April….
Winds will pick up today as a strong cold front & the jetstream are set to blast through tonight bringing Arctic air and snow. Snow should begin falling between about 9 p.m. & midnight as temps plummit into the teens & 20′s.
The snow should be heaviest during Thursday morning as the cold front pushes through and then snow showers into Thursday night. Models have a bit more moisture in the storm than yesterday. The Euro still says only .25-.5 inches of liquid, but GFS & the NAM are both consistent the last few runs with .75-1 inches.
This is a cold storm with snow levels dropping way below the valley floors. Highs tomorrow may not get out of the 20′s at lake level and will stay in the teens above 7000 ft. Snow ratios should be around 12-15:1 at lake level, 20:1 above 7000 ft. and up to 25:1 above 8000 ft. Because of the Euro I will stay with .5-.75 inches of liquid to be safe but it could be more.
That’s 6-12 inches at lake level, 10-15 inches above 7000 ft., and 12-18 inches on top of the mountains. Along the crest we have the better chance of hitting the 1 inch mark so we could get some resorts along the crest reporting 2 feet by Friday morning. Scattered snow showers could linger Friday as the main core of the cold low moves through. Highs will be in the 20′s & 30′s.
Don’t be caught off-guard by this storm. It has been warmer lately and no snow for about 10 days now. This storm is cold and it will pile up on the roads. We will clear out and begin to warm up over the weekend back into the 30′s on the mountains and 40′s at lake level, may even break 50 on Sunday.
The next weak storm for Monday has been trending further North. That means we should just have some scattered light snow showers at best and a little cooler temperatures on Monday. Then we have another brief ridge with nice temps for Tuesday and Wednesday.
By Thursday the pattern over the Pacific is changing. We are going to have retrogression the ridge to just South of the Aleutian islands and a low that is going to setup in the Northeast Pacific. This is the pattern that has brought us some of our big snow weeks this winter. The difference this time is that the jetstream is weaker since we are in spring.
Still, we could have a chance of decent cold storm next Thursday followed by several waves rotating into the coast for about a week. Right now the models have the storm track just to our North after the Thursday storm. We may just have a week of being brushed by the storms with light amounts of snow and cooler temperatures.
If the low in the Northeast Pacific sets up a littel further South and the trough is deeper down the West coast then we could accumulate some decent snow total for April over the period. We are going to have to watch how everything comes together over the next week, but just know that the ingredients are there for one last snowy period at mid-month. Stay tuned….BA
