FY-3D will be launched by the CZ-4C (Y21).

Satellite and launch vehicle will be sent to Taiyuan in early July.

This will be the return-to-flight for the CZ-4C after the 3rd stage launch failure on August 31, 2016, resulting in the loss of Gaofen 10.
***

Assuming that this launch campaign is proceeding on schedule towards November 15;

And, given the assumptions of identical LV, identical launch location, and a need to place FY-3D into a SSO matching its 3 predecessors, with a matching LTDN to one of its predecessors, etc.:

Satellite     Date/Time UTC
FY-3A        May 27, 2008, 03:02
FY-3B        Nov 4, 2010, 18:37
FY-3C        Sept 13, 2013, 03:07

It appears that launch time would be near either 03:00 or 18:30 UTC.

There's a posting at the end of the FY-3A launch thread from January 2015, stating that it reached the end of its operational life.  Its place in China's meteorological polar-orbiting satellite constellation appears to have been taken by FY-3C.

If there is a need to augment or replace FY-3B, then that would further narrow down the launch time to ~18:30 UTC on November 15.

Is this an accurate deduction?

I suppose confirmation (or not) will come when the NOTAMs for this launch are published.

If anyone needs some official confirmation that this launch is for the FY-3D, here is an article today from the China Meteorological Administration's National Satellite Meteorological Center (NSMC) that confirms the launch is on.  ;)

https://directory.eoportal.org/web/eoportal/satellite-missions/f/fy-3 has detailed technological descriptions of the FY-3 series and instruments on board.

It will take some time until we have launch confirmation.

Apparently launch took place
From weibo microblogging:
"The first time to the scene to see the satellite launch Taiyuan satellite launch center. Meteorological satellite launch. Very shocking, very spectacular!"

Are there any secondary payloads on board? None of the news reports I saw mention any, if there were one.  :-X
