An unusually strong “trough” (a bend in the winds that points to the Equator) aloft will be moving across our region today, and as it does, it will be clustering storms, much like they were bunched together two days ago. Remember that those bunched thunderheads came through in a band about mid-day. Something similar is foretold for today, except a little later. We hope that it takes a little longer than about 25 minutes to go through today, too. Violent weather is expected in AZ today, too, with the PHX NWS office particularly worked up by this possibility and that office has already issued public advisories about frequent lightning, terrific winds, and huge dumps of rain.
Dry and fall like days will follow today…..meaning morning low temperatures will probably drop into the 60s here as the dry invading air moves over us. With the lower sun angle these days leading to deeper blue skies overhead, the lower morning temperatures, you will definitely be thinking about college fubball in the days ahead.
Pay especial attention to what Bob has to say, our premier senior heavy weather forecaster, and your NWS for watches and warnings. Mike at the U of AZ will be weighing in as well later this morning. Could it be a tube day, too, somewhere? Will be watching.
Not very certain there will be any more August rain here after this, a very dark thought. As you know the chances of rain start to decline at this time of year.
Yesterday’s clouds (not in chronological order, just because…)
Maybe I make it too easy for you every day…
Ice developed early and often in those morning Cumulus as they transitioned to weak Cumulonimbus clouds with tops that weren’t so high, but considering how early that happened, it led someone to think that it might be a really good thunderstorm day. But then the air aloft dried out and those Cumulus tops couldn’t reach the ice-forming level by afternoon, which was quite a disappointment for someone.
