The Atmospheric River on the Equinox. Expect rain this week after final pleasant summer day. COVID School exposures list.

The air is clear! Our first Atmospheric River will greet us for the fall equinox which is 6AM Tuesday morning.

Here is the jet stream forecast starting with today and moving to every day this week. The more it points at us the more moisture we are likely to get on our doorstep. You can see that today should be mostly dry whereas Tuesday, Wednesday and Thursday are probably going to be wet. Maybe very wet.

Notice the jet points back at us on Saturday and Sunday too. It is definitely fall.
