...synopsis...
a mid-level trough will advance from the great lakes to the western
atlantic on sunday. to the west, a ridge will remain centered across
the western conus. on the eastern periphery of this ridge, a
secondary mid-level shortwave trough will move into the upper
midwest. a very strong (1040mb+) area of high pressure will build
into the eastern 2/3rds of the conus sunday and push a strong cold
front into the gulf by sunday evening.
...south florida...
a weak mid-level shortwave trough will approach the west coast of
florida on sunday morning. as this trough advances east, isolated to
widely scattered thunderstorms are possible across far south
florida. weak lapse rates should limit storm intensity overall.
storms should wane by the evening as the boundary layer cools and
northerly flow strengthens and brings cooler, drier air by sunday
night.
