"Weather temporarily disappearing"

#PokemonGO: The weather where I am has just vanished; no icon or anything. It happened at exactly 1500, transitioning from cloudy to vanished. This has happened before on the hourly transition points, but only for a few minutes; it's been 17 minutes so far. Anyone else have experience with this?Update: Been 90 minutes now and still nothing. Others in the same area reporting the same thing!Update 2: It came back on at 1800, so was down for exactly 3 hours. Other people nearby said the same thing, but others said they had weather fine. I'm conjecturing that, like with EX raids, the weather may also be governed by Level 12 S2 cells? via /r/TheSilphRoad http://ift.tt/2DgC57J
