.SHORT TERM...
(Rest of today through Friday)
Issued at 1214 PM EDT Thu Apr 18 2024
The western Atlantic surface high continues to play the dominate
roll in stable atmospheric conditions to wrap up the remainder of
the week. As the high shifts eastward, the winds will veer and
allow for a more distinct southeastward wind flow. With this
assistance, it will allow for more tropical moisture and an
increase in warm air. The warming trend will continue tomorrow
afternoon with highs rising into the mid to upper 80s along the
coasts with the potential for low 90s in the far SW interior. Far
interior RH values will drop into the mid to upper 30%, but weak
wind speeds should help keep the conditions from red flag/fire wx
concerns.

.LONG TERM...
(Friday night through Wednesday)
Issued at 224 AM EDT Thu Apr 18 2024
Heading into the weekend, the mid-level high begins
to break down as a southern stream trough emerges across the
northern Gulf of Mexico Saturday into Sunday. While the trough
axis will not extend all the way south into southern Florida, it
will pinch the high aloft southward a bit. A reinforcing trough
emerges Monday into Tuesday which will push the high aloft into
the Caribbean.
As the trough enters the Atlantic off the Carolinas,
a surface low may develop and push the surface boundary southward
into the peninsula of Florida with the potential for convection.
Rain chances will be highest over northeastern portions of the
forecast area, mainly around the Palm Beaches, but will still be
relatively modest. To close out the extended period, the surface
boundary could pass south into the Florida Straits allowing for a
period of northerly wind flow to return with some drier and
slightly cooler air. Still some uncertainty that the boundary will
be able to clear through but the possibility remains high enough
to mention.
