Rarely do passing lows get a two chances to produce rain, but the low passing overhead today and tomorrow, does. Ten days from now, its overhead again! How funny izzat? And precipful, too.
Measurable rain will fall today in Catalina CDP (“Census Designated Place”, i.e., its not a city), and in about 10 days when the SAME low returns after a boomerang trip down Texico way, thence to Baja, thence to so Cal, and back over Arizona on the 10th-11th after picking up some juice over the east Pac.
Thinking, as you are now, of a minimum of 0.05 inches and top of 0.50 inches, the latter larger amount if projected afternoon thunderstorms land on us. Thus, best estimate, average of those two extremes, thinking Gaussian conceptual model modal value here, about 0.275 inches.
BTW, should be something in the way of an arcus cloud, or a batch of low scudding clouds underneath Cumulus and Cumulonimbus bases this afternoon as a windshift to the NW comes through in the afternoon or early evening hours, well in the next 18 h or so. That could be a dramatic sight, and with that windshift, the temperature will drop 5-10° F.
When the low trudges over us the second time around in mid-October, the estimated extreme amounts are a trace minimum, and 1.00 inch max, in other words, pretty clueless here about how much could fall the second time around ten days from now.
If you don’t believe me about all this, here are is the WRF-GFS prediction for this afternoon, followed by the WRF-GFS model prediction 10 days from now, today being October 6th, in case you don’t know what the date is today, maybe you’re retired and lose track of the days and dates because you don’t have a lot to do everyday, just kind of sit there:
Yesterday’s clouds, punctuated by a large worm
However for a moment, we did have a shower threat move toward us from the south, this:
The End
Hi Art: That seems like an unusually long time for a low to exist, let alone come by again for a “second debut”. Reminds me of a cut-off low- the kind we sometimes get here in late spring or summer. Sincerely, Roland
p.s. Hurricane Oho remnants forecasted to swing up here in a couple of days.
Oho’s track reminds one of the track of Olga, the typhoon remnant that deepened explosively as it approached the Pac NW coast and became extratropical and was ultimately responsible for the infamous Columbus Day storm of 1962 that produced winds of over 130 mph. Billions of board feet or timber went down.
And, the World Series in SFO was rained out for the third day in a row, a record at that time.
Yes, tracks like “Joe” are pretty darn rare.

Always nice to wake up and see pictures of people in Oro Valley getting shafted.
That is funny, Russ! Wish I’d thought of it.
