@BillW,
13 forms of weather:
1. hail storm
2. calm, clear skies, temp 77. Editor's note: That's nice. Very Happy
3. dust devil
4. EF 5 tornado
5. Light drizzle. Not enough to Need an umbrella but enough to mess with your glasses.
6. El Niño
7. Partly cloudy, chance of rain. The universal forecast
8. Category 5 Hurricane
9. Blizzard. My favorite weather event.
10. Stalled out front
11. Sand and dust storm
12. Heavy rain - day and night, flooding
13. polar vortex
Any other takers for the next 13?
