Has the RRFS been doing pretty well?  I honestly haven't been paying enough attention to it as I probably should have lol.

It has had its ups and downs.

The biggest issue is that everyone looks at the simulated radar reflectivity output from it, which runs very hot, making everything look like a sup ready to produce the next EF-5.

It hit 94° at ORD and 95° at MDW today.

Both locations were 89°'d yesterday, while all inland areas hit 90°+.

I know that I have brought this up a few times over the past couple of years, but it finally looks like it is going to happen...

NOAA sent out a TIN/PNS today regarding the decommissioning of the NAM (And other guidance) in favor of the RRFS. This change is currently set to occur in early 2026.

all bark, no bite…

Made it up to 94° at ORD and 96° at MDW today.
