So tomorrow, the NWS forecasts wet bulb temperatures in parts of the US are so high, that people will die if they aren't in air-conditioning. You can't really do anything in wet bulb temps above 90F, and you die in wet bulb temps above 95F.

And it's only June!

@pearlbear hey, mind if I ask what app you're using to see that? I've never seen a system that showed wet-bulb temp predictions
@arcade @pearlbear NOAA/NOA has WBGT listed as an experimental feature; it's one of the drop-down map display options at https://digital.mdl.nws.noaa.gov/
