.PREV DISCUSSION... /ISSUED 1025 AM CST Tue Nov 03 2020/

Scattered showers and thunderstorms are expected to affect portions
of the desert southwest today, in vicinity of a weak upper low
moving across the area.  Cool temperatures aloft and sufficient
mid-level moisture will promote convection, but weak shear and
limited CAPE will preclude organized severe storms.

Otherwise, no thunderstorms are anticipated across the CONUS today.
