Preview of this afternoon/evenings activity. #AZWX #TUSwx #SierraVistaAZ #FtHuachuca.
SPC RAP valid +6 holds H5 heights at 594 dam, maybe holding subsidence but despite that, instability is enough to overcome the CAP along our ranges with orographic lift. TCU's & a couple CB's w/ strikes in the AO already.
I don't recall seeing this much instability all season - coupled with these theataE & PWAT numbers. Subsidence & CINH diminishing now as well! #AZwx #Monsoon2025
My first to hit town in 5 yrs here.
