It's exciting to see so many robust discussions about NOAA's new RRFS model. To help communicate what it is, how it works, and its future, GSL developed a brand-new webpage, just launched today. I hope that gsl.noaa.gov/rrfs will be a helpful resource for years to come
My *personal* thoughts on RRFS:
1. Current framework is unsustainable. Running multiple modeling systems drains NWS resources, limiting R2O. Consolidation was inevitable.
2. Initial transition probably will help some forecasting capabilities. Others, maybe less so. 1/
3. Physics upgrades have improved RRFS very recently
4. It operationalizes sorely-needed fire and smoke/dust applications
5. MPAS-RRFS (v2) is the first model to outperform HRRR in testbeds, and better physics, JEDI, and satellite DA should make it even better in the next year 2/

As part of @POTUS’ Investing in America agenda, this funding will help increase lead times for fire weather warnings, speed detection of fire starts, & provide more real-time actionable information to prevent wildfires & keep communities safe. noaa.gov/news-release/biden-…
They said, no doubt! Coach loves coming out and meeting people in town after games. And they showed us on their phones a place that was one of his favorites. So it was set that our mission for the rest of the night was to find Mike Leach on the streets of Pullman. 6/
Modern natural disasters occur at the intersection of natural events and human decisions. A high-end hurricane landfalling near a metro area of 760k that constructed 400+ miles of shallow canals at the wide mouth of a river is certainly an example.
