You can check here and see what was used for what forecast for the NBM at a particular hour. The models above were from me selecting 6hr snowfall at hour 42. https://blend.mdl.nws.noaa.gov/nbm-dashboard

Point and click are basically the NBM fed into a forecast graphic computer system. These are the model runs that went into the 18z NBM for snowfall at hour 42. So it's made from mostly ensemble members, short range models, and hasn't incorporated any data from the 12z/06z Euro at all that I can see.

The NAM and 3k struggles at times by overemphasizing terrain features. That leads to wild looking precip output maps. They are especially prone to it outside 24 hours.

Really poorly.

Weather Next/Google AI at 12z was nearly a carbon copy of 06z.

Ironically, it actually aligns with the Euro/EuroAi/WeatherNext 06z/GFS/Canadian/RGEM at this point.

That is likely the 1/10 chance map.

My forecast also says 1 inch or less. Not surprisingly, that last NBM map shows 1 inch or less in my area.

Not surprised by a WWA for my area. Not sure if the models will be correct, and there are a few now that are misses. I think they likely based everything off the NBM which is ultra dry over my area for some reason. I assume it's got heavy influence by hi-res models, even though they are very out of their range currently.

I would think 1.5x those amounts at minimum with the entire column so cold.

Courtesy of Bouncycorn. This is a 10:1 so multiply by 1.5 to 2.

I was just looking at that. It seems to have broken the 18/6, 12/0 cycle.

12z AI Euro beefed up QPF vs 00Z. It be breaking the cycle.

How similar are the WSW criteria for those areas? I know mine is different than Knox which is different than the southern border counties. I think 2 inches anywhere in their CWA is WSW criteria.

The 06z Weather Next/Google AI run was similar to, if not more robust than the 06z Euro.

I do expect the 12z to cut totals in half on the west side, as it's done for days now.

That other storm is the one that's going to shaft us next week. But no worries at all or need to be sorry!

If we could make free throws we'd be 18-2 or something close to that.

I refuse to kick at the Euro's football. But it's moving towards the RGEM with each 18/6 run.

This 18/6 vs 12/0 Euro thing continues I see. So strange.

Probably time for a February thread. The Euro is already trying to shaft us with a system next week that looks about like this one. Weak sauce here and it buries NE Georgia, South Carolina and North Carolina. Meanwhile, the GFS gives us rain and smokes southern Kentucky with 6 inches. So we are right in the middle of the two, but we know it'll either fade far south or go north.

You could have the issues Carvers mentions, but across all modeling you're looking at 4-10+ inches at this point.

And by stepped back, I mean for those of us in the screw zone/western edge. It still pounds the far eastern areas with 6-10 inches.

Not surprisingly at this point, the Euro stepped back from it's 18z run. It's so odd that it's changing the same way every other run.
