just found the GOES16 webpage a few days ago; nice source for where clouds are. what were they using before?

A model can only be as good as the observations fed into it. Even if the model had perfect accuracy, if the observations aren't complete or accurate, the model predictions will have accuracy issues.

Goes 13 was the popular one. Wonder if this site did the switch yet. Just lower Res and unable to zoom or at least zoom with details I think.

The more important part to think about is... The "moving parts" on the map always moving or adjusting speed, so even though observations are fed into it now, it doesn't mean the observations will be exactly where it thinks it will be in 1-2 days from now. You know?


So the observations can be perfect, but the results can still change down the line.

Now this is breaking news... Euro snow maps and all free to post from Ryan's site.

For those of you not sure, Euro Model maps are hard to find for free because the data is expensive ($250,000). Not sure how's Ryan is able to do this. He said because he doesn't have overhead. Smart guy. Very Smart! This will spread the word more about him and his site.

WOW FREE EURO!

For those not sure, he's not with Weatherbell anymore. On his own but with a partner, Jörg Kachelmann.

Here is the site. Temps and all. He said Precip will be added this winter.

The new JPSS data I believe will get fed into computer models to help with forecasts

Tropical TidBits site just added something useful for snowdepth maps...

"December 3: New snowfall products ["Snow-depth change" for GFS, NAM12, and HRRR] and [Snowfall (Ferrier) for NAM3] have been added. These are likely more realistic than assuming 10:1 snow/liquid ratios."

Does anyone know of any links for archived model data? Say, I want to see 850 mb temperature maps on a particular day 20 years ago. I'm sure it's been discussed before; can't remember.

Hard to find with maps. I got 2.


Try this. Archived since 2007. Scroll down a bit to North America "850mb Height/Temperature". Choose the folder with the date, then choose the image. Hard to read maps.


NWS DIFAX Map Archive




Then you can try this as well.


https://www.esrl.noaa.gov/psd/data/histdata/


Randomly picked todays date in 2007. 850mb temp anomalies
