Here is the AI summary of the changes:
Effective August 31, 2026, the National Weather Service (NWS) in Silver Spring, MD, will implement the Rapid Refresh Forecast System (RRFS) and RRFS Ensemble Forecast System (REFS), replacing the legacy NAM, HREF, SREF, and HiresW models. Other 2026 changes include updates to climate data assimilation (CORe), Day 4-5 excessive rainfall discussions, and the transition of GFS model products. [1, 2, 3, 4]

- CORe Implementation (Mar 2026): The Climate Object-oriented Reanalysis (CORe) replaces the Climate Data Assimilation System (CDAS) for atmospheric reanalysis, offering improved data from 1950 to present.
- ERO Enhancements (May 2026): Day 4 and 5 Excessive Rainfall Outlook (ERO) discussions are being integrated into the QPFERD product.
- GFS Product Changes: Public comments are being solicited for the proposed termination of various Global Forecast System (GFS) products. [1, 2, 3, 4]
Operational Changes & Notices
- NOMADS Upgrade (Feb 23, 2026): OpenDAP access is being retired, requiring users to switch to grib filter or HTTPS downloads for NCEP model data.

New update from the National Weather Service includes Bloomignton.
The latest severe weather outlook issued from the National Weather Services's Storm Prediction Center now includes a slight risk for Bloomington Indiana. Yesterday it was a marginal risk. It also includes a moderate risk for Oklahoma, Kansas and Missouri which is typical 'tornado alley'.
Who's ready for snow in May?
Well, specifically the GFS is giving us snow for May Day.
The big news is the severe weather outbreak in the middle of the country today. If you have family in orange shade area, you should call them and warn them about the possibilty of tornadoes today.
Specifically Wisconsin!
But, believe it or not, the Polar Vorttex will try to make a cimeback but I doubt we will see any snow. There might be snow in Canada and in the extreme nothern Great Lakes and in Maine but not in Indiana. Watch how the red heat goes to green and blue cold on the GFS model.
From 87 degrees to 37 degrees.
That's what happened in Bloomington Indiana yesterday. This is likely a taste of what summer has in store for us. If you haven't heard it yet, a "Super El Nino" is predicted for this summer.
The extreme heat is diminishing any chances for snow for this month. Friday night is the last chance to see snow.
The Ides of March will bring tornadoes and snow to south central Indiana on Sunday.
Beware the Ides of March!
.LONG TERM (Sunday through Friday)... Issued at 248 AM EDT Sat Mar 14 2026 Sunday and Monday... Guidance continues to agree that a deepening upper trough will produce a potent low pressure system that will move into the lower Great Lakes by Monday morning. 850mb winds in excess of 50kt will pump warmth and moisture into the area Sunday. High temperatures could reach around 70 degrees, with surface dewpoints in the 50s. Guidance is speeding up the cold front, with the potential for it to arrive in Indiana near 00-03Z Monday and moving out of the area by 06-09Z. The system will have some instability via strong advection of warmth and moisture, but arriving earlier could add a bit more instability. With strong wind fields in place, it wouldn`t take much instability to bring down damaging winds at any rate, so will continue to mention the severe threat Sunday night. Damaging winds will be the primary threat, but a few tornadoes may be possible along the line storms given the shear. The strong wind fields will lead to another breezy/windy period Sunday into Sunday night, with gusts near 50mph possible outside of any convection. For now believe winds will remain below High Wind Warning criteria, so do not feel a watch is necessary at the moment. A Wind Advisory will likely be needed though. Wrap around precipitation on Monday will be snow as much colder air moves into the area. Some light accumulation may occur. Temperatures on Monday will only peak in the upper 20s to lower 30s most areas.
