This Is Spring? Snow Forecast Map

This is spring? Really? Here’s the snow forecast map for 8 April 2018 from:

8 April 2018 Snow Forcast for the USA

I was looking at the long list of cold, snowy, and generally non-spring places at and got to wondering what all that wold look like on the predictions map. It looks like a lot of snow from coast to coast is what it looks like. All the way down to Texas, Tennessee, and North Carolina.

Now I don’t know what normal spring planting dates are for those places, but I do know it’s darned hard to plant in a snow storm.

Now this isn’t the whole story. Note that California only shows a small spot of snow in the Cascades at the Oregon border. Yet it’s raining and cold in San Jose / Silicon Valley; and that means snow in the Sierra Nevada most of the time. So what’s the snow report / prediction?

This is from 5300 feet elevation. The top of Squaw Valley is 8200 feet. What’s 3000 feet higher is snowier…

Current conditions at
Lat: 38.735819° N Lon: 120.241583° W Elev: 5240 ft.

Heavy rain. Lows 34 to 48 higher elevations…46 to 52 lower elevations. Prevailing south winds 10 to 20 mph with gusts to around 45 mph…except southwest 25 to 40 mph with gusts to around 55 mph over ridges.

At lower elevations, heavy rain showers. At higher elevations, heavy rain showers in the morning, then rain and snow showers in the afternoon. Breezy. Highs 38 to 52 higher elevations…47 to 57 lower elevations. No snow accumulation lower elevations…up to 2 inches higher elevations. Snow level 7000 feet in the afternoon. Prevailing southwest winds 10 to 25 mph with gusts to around 50 mph. Over ridges, prevailing southwest winds 25 to 45 mph decreasing to 25 to 35 mph in the afternoon.

Saturday Night
Mostly cloudy in the evening then becoming partly cloudy. At lower elevations, a chance of rain showers. At higher elevations, a chance of rain and snow showers in the evening, then a chance of snow showers after midnight. Colder. Lows 22 to 37 higher elevations…35 to 41 lower elevations. No snow accumulation lower elevations…up to 1 inch higher elevations. Snow level 6000 feet decreasing to 5000 feet after midnight. Prevailing southwest winds 5 to 15 mph with gusts to around 40 mph…except southwest 20 to 30 mph over ridges.

Mostly sunny. Not as cool. Highs 39 to 54 higher elevations…52 to 62 lower elevations. Prevailing southwest winds up to 10 mph shifting to the west in the afternoon. Over ridges, prevailing west winds 10 to 25 mph decreasing to up to 10 mph in the afternoon.

So a couple of inches of snow between now and Sunday night.

Looks to me like the Intellicast snow map is being conservative and not showing all the snow we’ll get. Or perhaps just not fine grained enough to pick up the Sierra Nevada Mountains…

So, this is spring? A warm spring? I don’t think so Tim…

    Yep we are getting some “rocky mountain sunshine” right now, I might have to scrape it off my windshield before I head home from work.

    Hi EM,
    This is a warm system. It’s 57F (as of 645pm) here in Carson Valley at 4800′. It’s 47F in Stateline and rainy/wet. Echo Summit (7400′) is still wet according to CalTrans cameras. The coldest I can find in the Tahoe area is 38F at Lois Lake (8350′). CalTrans map is showing no chains required anywhere–tho’ the plows are fully deployed.

    Yes, it’s starting out warm. Notice the prediction is for lowering snow level over the next few days.

    BOTH those links are really something.

    Thursday was 34 degrees. Friday was 72. Today they are calling for snow. And of course on MOnday.

    I just wish it would make up its mind.

    Near Yakima/Ellensburg (WA) region at 1,000 to 2,000 feet a big rain just ended with temp. about 40 degrees F.
    West of us at about 4,000 feet the temp is about freezing. 8:30 AM.
    Maybe 6 -8 inches of snow up there tonight.
    The only thing that looks like spring around here are the Gold Finches!

    Note that the satellite that wandered was known about and (mostly) taken into account a few (2, 3) years ago. The current paper is about a rigorous accounting (stat-math stuff) of the numbers.
