Well, weather rules — not climate.
While the People’s Climate March in Washington DC Saturday (April 29) will enjoy unseasonably warm weather, some of the Sister Marches out West won’t be so lucky. There are winter storm warnings, watches, and winter weather advisories in effect for portions of nine Rocky Mountain and High Plains states.
I’m sure the warmth in DC will be pointed to as evidence of global warming during the march. But check out this forecast of the regions of above and below normal for midday Saturday (graphic courtesy of Weatherbell.com):
Temperatures will range from 40 deg. F below normal to 27 deg. F above normal. This is what’s called “weather”. Depending on where you are marching, you will either be bundled up against the cold and wind-driven snow, or in shorts and sweating.
At the same latitude, at the same time.
