I just saw myself licking the thumb, putting the arm out of the window, waiting a bit and thinking "ok the thumb got chilled enough so it is great time to pay that bill".

Interesting point! It seems to me that the economy regularly takes a beating on extreme weather days. However, these things are factored in. For e.g. whenever there is a cyclone brewing near the Louisiana coast, gas prices go up.

If there is a blizzard, people stay home. Then there are forest fires - these might cause property destruction and have a long term health impact - directly and indirectly affecting the economy. Although the exact timing of these events are not predictable, a huge part of our economy - the insurance industry tries to factor extreme weather into account. Similarly, mining during windy days should even out, given enough players are invested.
