...DISCUSSION...
A weak upper-level trough is forecast to move eastward across the
southeastern Gulf of Mexico on Sunday. Ahead of the trough, a moist
airmass will be in place across far southeast Florida. As surface
temperatures warm during the day, isolated thunderstorm development
will be possible in the vicinity of Miami. A few thunderstorms could
also occur ahead of an upper-level trough moving toward the coast of
California. The greatest chance for lightning is from near Eureka
southward to near San Jose. Weak instability is expected to keep
thunderstorms at non-severe levels across the continental United
States on Sunday.
