Sky to do to a lot of things today

Keep cameras at the ready.  Have some nice lenticulars in the lee of the Catalinas this morning if u look.

FROPA (weather text for “frontal passage” and cold air burst into Oro Valley and Catalina likely to be fronted by a lower arcus-like cloud that comes over the Torts later today.  That should be dramatic, though personally I will complain about cold air right after it hits.

Still riding the forecast wave  of 0.3 inches, though mods have varied from nothing to about that now.  Yay!


Since its already windy, there’s a good chance of more windy (from the SW) right up until FROPA when the wind will turn to the NW for a while.
