I just modified your code and took out any reference to the LCD that you have and the libraries etc. (spi, gfx, pcd8544) as I do not have one of those devices. I was using just the serial port for debugging.
I also took out all display.xxx calls.
The code compiles and connects, but then the WatchDogTimer gets tripped and the chip resets.
I am using a Generic ESP-12-E and not the huzzah module.
this is an example of the output:

- Thu Oct 29, 2015 9:32 am #32549 Make sure respBuf is global (declared outside any function) and StaticJsonBuffer<3*1024> jsonBuffer is local (declared inside a function). That is all I can remember about using the ArduinoJson library. Stripping out the LCD display code should work as long as other changes are not made.

- Thu Oct 29, 2015 10:41 am #32559 I posted on github the esp-pcd-weather demo program with all the LCD code stripped out. The weather data is sent out the serial console. Works fine on my system.

- Sun Nov 01, 2015 2:42 pm #32767 Unfortunately it always sets off the watchdog timer for me with Arduino.cc version 1.6.5.
I updated and downdated my esp8266 (via boards manager) install and updated and downdated (via library manager) the arduJson library (5.04 is my current version) and it was the same. Your code really only uses those libraries . It might be that I am using a esp-12e but I doubt it.
Currently I am saving data to thing speak
https://thingspeak.com/apps/matlab_visualizations/31295
You can see how cold my beer is at the moment (I tell a lie as I don't drink).

Apparently thingspeak can also send data back across an API, and 2 of the fields are : TZ and offset. So if I could just access that things would start looking rosy again.
