It definitely sucks that you may be missing out on a memorable storm for RI. They are rare, compared to other parts of New England. That being said, you do have your two week travel period set during the middle of what is usually the best period climo-wise for good storms in RI. Mid-January to Mid-February is when things tend to click the most for us in RI if you look at storm records. I'm guessing your two week period of travel can't be adjusted, but you would have less of a chance missing out on our storms in SE NE if you moved that winter travel period a little.

Enjoy it when you get back. It will still be here with all this cold. With some other chances to cash in.

I've always wondered how much Environment Canada uses their own models for forecasting vs the other globals that are available to them. Are the Canadian models tuned for their geographic location? CMC/RGEM is an outlier right now, so I wouldn't look too much into that until there's agreement. Usually the NAM is good with picking up those warm profiles but you need to wait to 48 hours before go time to get that data accurately modeled.

4” here. Extra wet stuff with some fluffier snow towards the top.

About to make the trip home to Bristol from Providence, this should be fun! Eyeballing a couple of inches on the ground here in Providence. There was only a coating left from this morning before the snow picked up at around sunset...

I'm taking the over that @Franklin0529 will likely lose some money today.

Maybe about an inch from this morning in Providence. Light snow at the moment but not really sticking. If heaviest bands can hold off until surface temps drop a few degrees after sunset, then I'm optimistic the 3-5+ will happen down here, but I feel it's very temp dependant on this storm... even when it was snowing heavier earlier this morning, it was having trouble accumulating at 32/33 on the way in to work. Also a slight warning sign that the kuchera accumulation ratios are lower than the 10-1 accumulations on most of the snowfall output maps (taken with a grain of salt, of course)...

big flakes here...

Enjoying a good early morning fingering here…

I don’t believe RRFS v1 is ever going into production. It’s based on FV3 which they found to be not great. There already is a second version of the RRFS v2 which will be based on MPAS which will likely end up the replacement for the NAM, NAM 3k, RAP, and HRRR… https://gsl.noaa.gov/research/predictions

That band looks to be snow and headed directly towards @Ginx snewx. Someone is gonna pickup a quick couple of inches in that.

How do we know you’re not an AI bot from the future, here to warn us about snowless 70 degree January days in Central Park in the year 2029?

So just so I understand your thoughts on this topic… You are having difficulty using “AI” based weather models as a forecasting tool, because there isn’t as much published scientific research into how transformer models and training data affect/determine the model output results versus the established research on numerical based models? There have been published papers on this topic over the last few years circulating on the Internet. A lot of it is well over my level of understanding but it’s much more interesting learning about this usage of AI/machine learning than the typical slop being commercialized and promoted to the masses.

Brutal… lol…
