Christmas has arrived early! The HRRR-based SPC Mesoanalysis, and RRFS North America Domain forecasts postprocessed by the mesoanalysis routines, are on NOMADS! It’s in its parallel evaluation until early October. Then it’ll be operational.

New offerings from SPC. You can check them out on NOMADS. Including, for the first time, our mesoanalysis grids (in netcdf format). We also use our mesoanalysis code to post-process the entire RRFS domain for every forecast hour and every initialization. nomads.ncep.noaa.gov/pub/data/ncc...

It remains to be seen how far the east shift can continue - so far Lowell is on track with NHC and most guidance, but the NHC forecast diverges beyond tonight as other models show more of a NE storm motion.

I've made these animations showing seasons' timelines as they appeared in real time before, purely in Python - and now they're rendered on the browser for anyone to create and view:

USAF recon finding Lowell slightly weaker but still a major, category 3 hurricane as it moves north. Models have continued to trend a little to the right and the threat for significant wind gusts (perhaps to hurricane force) have increased for Kauai County, particularly at higher elevations.

The NWS had another nationwide comms outage as storms were impacting parts of the country on Sat. While not as impactful as the outage during an early August outbreak, it's another concerning sign. Also: Lowell forecast shifting a bit east toward Kauai. balancedweather.substack.com/p/nws-suffer...
