.DISCUSSION...
Issued at 1203 AM EDT Thu Sep 25 2025
Weak surface high pressure will hold over the forecast area today
with continued warm temperatures. Scattered showers and
thunderstorms will develop this afternoon with the best chance for
rain over the interior as weak boundary layer flow will allow the
west coast sea breeze boundary to push well inland this
afternoon.
An U/L trough and associated cold front will move over north
Florida on Friday with an increasing chance of
showers/thunderstorms across the nature coast. The frontal
boundary will stall across north central Florida Friday night and
Saturday with a continued chance of showers and thunderstorms,
with highest pops central and north.
The U/L pattern will become more complex Sunday and Monday as a
weak rex block develops over the eastern U.S. A potential
tropical system is expected to move just east or over the
Bahamas...moving somewhat parallel to the east coast of Florida.
The rex block (with the associated cut-off low over the southeast
U.S.) will likely play a key role in steering this system.
The U/L rex block will begin to break down mid week, with surface
high pressure building back over west central and southwest
Florida. Temperatures will run several degrees above climatic
normals through the period. A chance of an afternoon shower or
thunderstorm each day.
