.DISCUSSION...
Issued at 204 PM EDT Tue Sep 23 2025
Showers and storms today have lingered off the coast of SWFL through
the day. Some of the coastal showers could move onshore as the sea
breeze develops. Later this afternoon into the evening, showers and
storms will begin to develop inland along the sea breeze boundaries.
Majority of activity will likely be south of I-4, similar to
yesterday. Though a few isolated showers could develop further
north. Heavy downpours could lead to areas of isolated urban street
flooding. Tomorrow will feature much of the same as the majority of
the moisture will be contained to south of I-4.
A frontal boundary approaches as the weekend arrives, bringing
increased rain chances throughout the region. Unfortunately this
"cold front" is not expected to cool things off. High temperatures
will still be in the upper 80s low 90s into next week. Low
temperatures could dip back down in the 60s for the northernmost
forecast area for a couple of days.
High pressure looks to build back over the area early next week.
This will allow dry air to filter, decreasing rain chances once
again.
Still keeping an eye on the tropics, as the NHC has 2 areas of
interest marked for potential development in the Atlantic. Still too
early to determine intensity or track of these systems, if they even
develop. We will continue to monitor the situation and update as
needed.
