I'm turning in, too. The smell has abated (yes, my sense of smell is still fine) so I guess it was a "quickie". Thanks to all for your help!

Nothing from the NWS, they tend to cover weather-caused oddities in their Area Forecast Discussions.
BTW, the smell may be coming from the ocean (don't know how far you are from it)... that's where the prevailing winds are coming from.
My nephew lives there now. Hence I've held back from jokes. Please ping me back if you know anything serious, ok?
Otherwise, I've missed out on fun FR trolling :)
THANKS!
