Discussion
A mid level trough combined with the development of the east and
west coast sea breezes helped to spark off scattered showers and
thunderstorms across the region this afternoon. This mid level
trough will slowly begin to move away from the region tonight and
any left over showers or thunderstorms will begin to diminish as
the evening progresses. The exception to this will be over the
local waters as well as the east coast metro areas where there
could be a slight chance of additional shower development during
the overnight hours. Low temperatures overnight will range from
the lower 70s across the northwestern interior to the lower 80s
across the east coast metro areas. The area of high pressure
located over the western atlantic will try to build its way back
over south florida on Friday. The trough will slowly continue to
move over the eastern gulf of mexico during this time frame.

Scattered showers and thunderstorms will develop along the east
and west coast sea breezes as they move inland. The greatest
coverage of showers and thunderstorms will be located across
interior sections and the west coast as a southeasterly flow
continues. The mid level trough over the eastern gulf of mexico
could help to enhance the shower and thunderstorm chances over the
gulf waters on Friday afternoon and evening. High temperatures on
Friday will range from around 90 across the east coast to the mid
90s across the interior sections.

For the upcoming weekend, the pattern looks to become a little
more unsettled as both of the GFS and the ECMWF show a trough
digging down into the southeastern portion of the country. At the
same time, a mid level feature in the northeastern gulf of mexico
will become trapped and it will try to interact with the trough to
the north. The trough will try to stall out and amplify over the
southeastern portion of the country throughout the weekend. This
will allow for higher rain chances across south florida during
this time frame. Shower and thunderstorms chances will still be
sea breeze driven, however, there will be more available moisture
to work with which will allow for coverage to be higher during
this time frame. The greatest coverage will still remain over the
interior and west coast sections during the afternoon and evening
hours.

For early next week, the latest computer model guidance continues
to show a tropical wave pushing closer to the region. This will
help to enhance the amount of available moisture in the areas
which will continue to lead to increased chances of showers and
thunderstorms. At the same time, both of the GFS and the ecmwf
continue to show a frontal boundary slowly pushing southward
towards the region and stalling out just to the north. This will
have to be monitored as the weekend progresses as the confidence
is low at this point in time with how far south this feature will
progress.
