Maybe it'll do atmospheric rivers for the west coast??

Ever look at a single snow forecast and think, "But what are the actual odds?"
The Probabilistic Precipitation Portal is a resource to help you get ahead of the storm by moving beyond a single number to give you the full picture.
Showing my town to very likely get 4-8 inches between Fri-Mon
I guess my response from yesterday didn't post.
Short version - I've been wanting something like this from NOAA.
Accuweather has it, but you can pick points on the map with specific altitudes.
I wish the NOAA forecasts for told you the altitude when you click on the map. The normal forecasts do and in our area it can be off by 2000 feet because it's the average altitude of the square you click in. And 2000 feet makes a massive difference for snowfall (like 2" of rain vs 3' of snow).
Here's my region

(My weather comes out of Wakefield Va but this one -Morehead City NC- gives a better map of my points of interest.)
>my region
The forecast was 8 inches & we got 7. Everything here totally snowbound, hhh.
Finally have a storm coming in where I can test this.
Since first playing with it, though, it no longer gives snowfall numbers when you hover on the map. Is that just me or did they remove that capability.
I can still get point forecasts for various points, but the closest one is a full 1500 feet higher than my location, which makes a BIG difference for snowfall totals, especially if the temperatures are on the snow/rain line
And now it's giving me numbers on hover again.
But then I switched from the "expected" view to the "high end" view and lost the numbers again. Then after a couple of minutes, they're back.
It seems to take a long time for the page to fully load
The "high end" view is *really* handy for planning for plowing and general chaos.
Very strange - there are cases where the same altitude only a mile apart are showing a difference of 4"(10"vs 14").
Still it looks like our max will be 12" with a only a 26% chance of 6" or more at the top of the 'hood and 14% at our house.
Weather.com is predicting 1"
Incidentally, for an area like ours, precise location matters, but the map is not very detailed - it's missing minor roads, even some pretty major minor roads. Seems to only have major highways.
HOWEVER, you can switch to night view, bring the weather map opacity to 0%, then wait to fully load, then hover over any location and get the numeric data (i.e. 2.1" for "expected" view or 14% for "probability of 6 inches or more" view)
I checked a couple of 'knowns' within a 10-mile radius here in the uber-flat lands. They were +/- 1 inch
