Johnny wrong note.

Touche. Unless we see some massive heat the last few days of the month then those departures will clearly be sunk and even +2 departures seem unlikely given where we stand now plus a couple of more negative departure days coming up before we warm up again.

Anyone know today's departures by any chance?

Models are bringing the coastal closer for midweek

 

 

No,  Really? Youre so intimate with the models, maybe you can force the coastal even closer with your Xbox Controller. LOL

The ridge looks north and high in amplitude instead of your typical Bermuda high position so maybe a lot more onshore flow?

 

Agreed but should get a more W-SW flow this weekend into early next week.  Nothing record but should see a warmer pattern once to Thu though the end of the month.  Id expect most places to fininsh +1.5 to +20

Despite the cool shot that is moving into the NY Metro area today, it appears that September will wind up with warm anomalies for the first time since June. Moreover, some of the long-term guidance has been persistently warm for October.

 

Even as it's early, I created some maps from teleconnection patterns that were similar to the 9/10-20 period and had evolved in similar fashion to the forecast for the next 15 days. I then took the cases with the best match for September 2014 and looked at the October anomalies. The map was strikingly similar to the latest CFSv2 monthly forecast. The forecast warmth on the GFS ensembles through the extended range lends support to the idea that a milder nationwide pattern could evolve for the start of October.

Of course, one should note that analogs are only representations. Some differences in detail are more than likely, but the broad insight that the month as a whole might feature widespread warm anomalies in the CONUS is consistent with some of the longer-range guidance.

 

Finally, October's outcome is not necessarily a good indicator for the upcoming winter. One early positive sign, if it is sustained, would be the persistent PNA ridging that has been taking place. Many more details remain to be resolved.

Hasn't it been discussed before that a warm October leads to a snowy DJF?
