That could be the FV3 cold/snow biases that led to its delayed implementation as the new GFS. The fixes were not tested during the fall or winter before the implementation took place.

We saw the same cold bias with the snow and cold forecast for this week.

Last October first freeze was 10/19, and we had 2 more freezes before the end of the month. This year low so far is 37 and no 30s in sight. 

Both last year and this year my first freeze was 10/19 with the average date of 10/25 IMBY. Still waiting on the first hard freeze here but that average date is sometime in the first week of November all based on my records here going back to 2005.

One needs to be cautious with the extended range GFS.

 I wouldn't trust any guidance showing sustained below-normal temperatures. Even the Euro had this weekend below normal in the 50s several days ago. I would also add that the pattern we are currently in would be a colder one come December January February as the wavelengths lengthen. It's a good sign to see higher Heights in the high-latitude regions hopefully this can stay as winter approaches

Regards to the MJO it is forecast to enter the cod according to most guidance or a very weak 4 5 or 6 phase. Is it safe to say that the mjo is not a driver for the next few weeks? Also when it enters a particular phase is there a lag time to our sensible weather?

The record +IOD may be disrupting or interfering  with the MJO. So other factors may play a greater role in our sensible weather. Such as the location of the perma-North Pacific ridge. The NP ridge has been helping to pump the SE Ridge in October. We’ll have to see how this evolves going forward.

Euro has a very wet and mild Sunday. Rainfall totals in the 1 to 2 inch range with highs near 70.

I honestly doubt we get into the 70’s with rain unless the brunt of the storm come in late tonight and very early morning than we get a warm day in the afternoon. I still think tomorrow all day is a wash out with low to mid 60’s for Central Park

Rain looks to move out by mid afternoon

We get warm sectored later in the day after the rain ends.  Deep SW flow and 850 mb temps around +15C. Best chance of 70 may be the usual warm spots in NJ.

we'll probably see some more 70+ days before it gets colder...November's average max is around 70...

Posters will be happy as long as we don’t get one in late December like 2013 and 2015.

70 isn't as rare as some make it out to be, we've hit 70 a few times in January too.

Even as high and mid-level clouds moved in to dim the afternoon sunshine, today was yet another balmy October day at the New York Botanical Garden. The high temperature reached 63°.

The last photo shows the two largest giant pumpkins on display. The one in the foreground weighs 2,116 pounds. The one in the background weighs 2,016 pounds.
