First, some techno-babble. Rain was an on and off event for Catalina and environs in the models run after run. A forecaster friend sent many e-mails that went from “looks good for rain” here, and just about as many that said, “doesn’t look good for rain.” In fact, the (WRF-GFS) model run for just 12 h before it rained, had no rain here, but just a bit to the north. What happened?
Here’s the amount of trough “sag” (“amplitude”, as we would say) over Arizona predicted just 14 h before it started raining in Catalina yesterday afternoon:
In case you think I am lying again, just because I am a meteorologist and say a lot of wrong things, below is the REAL map for last evening with wind data from rawinsonde balloons on it.
I hope you’re happy now.
Here’s what the temperature did as the windshift and rain began, in case you missed it:
The sequence: cloudy, sunny “sucker hole” (one of Biblical proportions), cloudy, raining, sunny, dusty.
