Had Illinois kicked the field goal, it would have been a one score game. Instead, it was a two score game and this allowed Purdue to run the clock for most of the 4th quarter.

Late in the 3rd quarter, Illinois makes a very questionable decision to go on 4th down behind 16-7. The conversion failed. I would have kicked the field goal.

There was a problem in one run of one member of the RRFS ensemble. That has since been addressed, but NCEP Central Operations policy is that means the 30-day pre-implementation cycle has to start over.

Penn State is losing to Northwestern 31-7 early in the 4th quarter. James Franklin wasn't the only problem at PSU. #PSUvsNW

I'm happy about the delay, but extending the lifetime of the NAM and HREF by only a few weeks implies a reason other than the utility of these models. Is there a problem with the RRFS/REFS or GFS update?

Outflow from leading precipitation can sometimes mask a cold front. Tonight, outflow from precipitation veered winds to northwesterly ahead of the cold front. The cold front is father NW and exhibits a wind shift to NNE and a significant decrease in temperatures and dewpoints.

I did a double-take when I opened the NHC forecast map for newly-minted Tropical Depression 19-E. Yes, it's expected to move almost due eastward. That's weird. I appreciate Eric Blake taking the time to point out what's affecting its track (see highlighted text in the discussion screenshot).
Map showing the TD 19-E NHC forecast cone from advisory 1 as of 8am PDT 29 September 2026. The expected track is eastward, an unusual direction at lower latitudes in this basin.Text from the advisory 1 NHC forecast on Tropical Depression 19-E:

"Although the system has become a tropical depression, the center is 
mostly exposed with moderate shear.  There is a slight chance of the 
system reaching tropical storm intensity later today before it feels 
the cold wake of former Hurricane Odalys by tomorrow.  The 
environment is expected to further dry out during the next couple of 
days with an increase in shear.  These factors should cause the 
depression to weaken by late Wednesday and degenerate into a post- 
tropical cyclone by late Thursday.  The NHC forecast is just above 
the model consensus.

The depression is moving eastward at 8 kt.  This general motion is 
expected for the next few days until dissipation while the cyclone 
remains embedded in westerly flow due to a northward-displaced 
near-equatorial trough, enhanced by both the strong El Nino event 
and western Hemisphere Madden-Julian Oscillation.  The track is 
close to a blend of the ECMWF and GFS models and leans toward the 
HCCA corrected-consensus model."

Now that the nor'easter completed its phase with a tropopause vortex and is decidedly non-tropical, let's look back at its structural evolution over the last day and a half, and why despite attempting to start the tropical transition process, it fell short of classification:

Amazingly, the hurricane drought continues with nothing in the foreseeable future. No hurricane season has gotten this far along without a hurricane in the past century, and during the more reliable satellite era (mid-1970s), the previous record latest first hurricane formation was September 11.
