After a week of unseasonable warmth, we’re returning to the expected 60s with a bit of drama. This time Ma Nature decided to imitate a snake.

Zooming way out, today’s pattern is even weirder. It appears to be drawing moisture from the Atlantic and Gulf, and carrying the moisture WESTWARD across the whole country. Looks like an Archimedes screw, and moves the same way!

There are two common sky rivers: the Pineapple Express pulling from the Pacific and flowing snakily eastward; and the monsoon pulling from the west side of Mexico and flowing straight northward. Today’s pattern is the exact reverse of the Pineapple Express.
