Monday snowfall estimates came in about the same as last night. 1 to 3 inches in town 7-8k ele , 2 to 4 over the upper elevations. Timing for the snowfall is mostly Tonight into Tuesday night. The models came in a wee bit wetter this morning, but not by much.

This still looks like the end of it through the end of April. There is a storm that will make a run for the coast toward the end of the month. At this time it is indicated to stay north. Whether there is more snowfall in May or Early June is not known.

Climatology:

As we get into Mid April and May…the higher angle of the sun is Summer like. Daytime heating is stronger and more daytime convection is noted. Additionally, the deserts really heat up fast after a storm leaves. Strong surface heating develops and rises…then spreads out and sinks from the upper levels. (Dibatic heating)

Upper levels highs are strengthened and the migratory upper jets that swing into the west coast spin up more on the east side of the trof, as the gradient becomes focused inland instead of over the far eastern pacific. This in general tends to pull storms east quicker to the north of us, rather than systems digging south like during the winter season. This is one reason why Spring storms are winder and have less moisture then Winter Systems. They are fighting an increasingly loosing battle within the change of season….

It def. did come in!

So how much did you get? At what elevation?

 

[zilla]

Well the snow came down to valley floor, and heard reports of half a foot and a little more above 8 thou.
Truckee should have even done pretty good because report from Portola said snow all day maybe 6 in. there.

Should be a little excitement if anybody went yesterday or today.

kirkwood reported 14", so that means Red Lake and Tragedy should be about the same.

I want to go, but can't find anybody who wants to go. I'm not gonna go by myself

Here in SOCAL the winter snow/rain was so little this season no resevior will release any water to replenish ground water.

I hope you NORCAL guys get some more snow to help limit the fire season.

Colorado has received over 3 feet this week!

It is interesting of what this storm is doing east to us ...

Colorado's snowpack has risen to 77 percent of the average seasonal peak, and the critical Colorado Basin, which provides water to more than 40 million people in seven western states, has grown to 85 percent of the average peak.

The usual measurements that compare the snow level to the average for a particular day are even higher, but they're misleading because in a normal year, snow would have already started melting by now, said Mage Hulstrand of the National Resources Conservation Service.

The storm is expected to move into Kansas and Nebraska later Wednesday.

In Wyoming, Melody Berg, an assistant store manager at Lowe's in Cheyenne, said snow blowers and snow shovels have been selling well.

Forecasters said the storm could drop as much as 15 inches of snow in western South Dakota by Thursday and lesser but still-significant amounts farther east.
