807 AM EDT SAT MAY 28 2016
Unsettled weather is forecast through the day across South
Florida, with a chance of showers and storms along both coasts.
Currently, showers and isolated storms over the Atlantic waters
are weakening as they move onshore. Have gone back and added a
tempo for a couple of hours this morning for TSRA as the lightning
activity has increased some this morning. The activity is forecast
to move towards the interior by this afternoon. VFR will be the
predominate condition, with brief IFR possible under heavy showers
.PREV DISCUSSION... /issued 429 AM EDT SAT MAY 28 2016/
With no major weather features impacting South Florida well into
next week, sea breeze boundaries will be the main driver of
showers across the region. Temperatures will remain seasonably
warm with the most likely area for showers and thunderstorms being
SHORT TERM /TODAY THROUGH MONDAY/...
Tropical Depression 2 remains poorly organized early this morning
as it moves northwestward north of the Bahamas. Located at 2 AM
EDT about 300 miles SE of the South Carolina coast, TD 2 is
expected to become a tropical storm, with the name of Bonnie,
sometime today, but will not be impacting South Florida.
Across South Florida, light to moderate easterly flow continues
and low level moisture has been sufficient for isolated to
scattered Atlantic showers overnight. A few of these showers have
impacted and will continue to impact the east coast metropolitan
areas. Expect this activity to gradually increase in coverage and
intensity after daybreak, with a few thunderstorms possible by
late morning. By afternoon, the Atlantic sea breeze will focus
showers more inland, so Atlantic coastal areas may dry some. Any
thunderstorms today could produce frequent lightning, but strong
convection is not anticipated. Activity will diurnally diminish
this evening, with a similar pattern forecast for Sunday. By
Memorial Day, slightly drier air in place will lead to a
reduction in shower/thunderstorm coverage.
Temperatures through the holiday weekend will generally remain in
the 80s for maxima (with some low 90s over interior and 70s for
minima. Winds will be noticeably less breezy than last few days.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
The drying trend that is forecast to arrive Memorial Day will
continue through much of next week. Although sea-breeze boundaries
and subsequent outflow collisions will still suffice for scattered
afternoon thunderstorms over the interior, the urbanized areas on
each coast will only have slight rain chances through the period.
Temperatures will be near climatological normals for the start of
summer, with highs reaching upper 80s on the east and west coasts,
then low 90s from The Everglades to Lake Okeechobee. Low
temperatures will be in the 70s.
Tropical Depression 2 should not have impact on South Florida`s
waters, as it is expected to move northwest toward South Carolina
and away from South Florida this weekend. East wind averaging 10
knots should prevail into early next week. A few thunderstorms are
possible, especially on Lake Okeechobee in the afternoons,
otherwise benign marine conditions will prevail.
