so the theory goes, as the temps rise, the upper-level cold lows will come later in fall and later in spring (response to southern hemi fall going later too).  global warming? i dunno.  climate change? likely.  global turbulence? ah, that’s the rub of it…

here’s the likely hooky culprit from yesterday pic i took.  green square is a rotating cu-nim, yellow cross is my ground station.

good pics and video at modesto bee.

from NOAA yesterday…..

It was an active afternoon and evening over NorCal with a
tornadic mini-supercell over southern Stanislaus county several
damage reports to structures have been received in and around
Denair...which is just east of Turlock. After examination of radar
imagery...video and eye witness accounts our office has determined
that a tornado struck Denair between 1:45 and 2:00 pm this
afternoon. A Survey team will travel to the city Monday to
determine the damage rating, path length and duration of the
tornado.
