Generally these kinds of amounts were observed over most of Arizona north of Tucson.  More chances for brief rain today, too, all of a sudden.  Mods had nothin’ yesterday, and YET, here it is, a rain.

Great sunset last evening, too, in case you missed it. Me, too.  Forgot my camera when going out, but did glimpse it as we drove home.

When you’re in the bowl, the “trough bowl: that is, good things happen, and like this morning’s surprise rain, being in the bowl means more rain might fall than expected, since those upper level troughs and all the good things they do, get stronger when they’re approaching the place where the “bowl” is, technically in the “mean trough position” where troughs reach their most southern latitudes.  And this is where we will be for at least the next week.

We therefore have three good rain possibilities, today, Monday night into Tuesday morning, and then something substantial on the 6th-7th, and the spaghetti plots make that last one look like a fairly confident forecast.  Here is one of those latter rainy maps for Arizona, ones we hope verify, because there because it looks grim for February after this:

Valid at 5 PM AST, February 7th.  Those green areas denote regions where the model has calculated that precip has fallen during the prior six hours.
