Weather desyncs when not in overworld

Partial clone of MCPE-131325. I do not know if this issue is identical, or only part of the original issue. Evidently when the player is not in the overworld the client thread does not receive weather update packets from the server thread.

Steps tor reproduce:

1. In the overworld, set weather to rain or thunder.

2. Make a nether portal and go to the nether.

3. Wait in the nether 20-30 minutes.

4. Go back to the overworld.

Expected result:

The weather is clear in the overworld.

Observed result

The weather is visually rain, but clear server-side.
