Ehhh... so it's a weather website? What's that got to do with whether I should get up >_<
Without checking the weather though, anytime it's rainy in the morning I always feel 300% more lethargic, as if some primal instinct is saying "it's raining out there, better just not."
I also have a folder of rain sounds collected off of archive.org and some other places, for when I want to get deep work like programming done. I feel much better at creative tasks when I'm relaxed by rain sounds.
