...Synopsis...
A 500 mb cyclone will meander across the Southwest as a mid-level
trough deepens across the Northeast, reinforcing surface high
pressure and subsidence across most of the CONUS, where thunderstorm
development should remain limited. One exception is the Lower
Colorado Basin region. Here, cooler temperatures aloft with the
mid-level low will promote enough buoyancy (albeit scant) and lift
to support isolated thunderstorms across far southeast CA today into
western and central AZ tonight.
