.DISCUSSION...
Issued at 247 PM EDT Wed May 14 2025

Current-Tonight... Temperatures are observed in the low to mid
80s early this afternoon, and areas across the interior are
already starting to touch the upper 80s. Calm conditions are
expected through the evening and overnight with lows falling into
the mid to upper 60s. However, a few areas will struggle to fall
below 70. Will be monitoring conditions for patchy fog development
overnight as winds become light and variable and dew point
depressions near zero. Current model guidance has suggested the
greatest potential for fog across portions of the western
peninsula, and have introduced patchy fog across areas of Lake
county should any fog drift eastward. Have also added patchy fog
along the Treasure Coast, as the forecasted conditions generally
favor periods of ground fog there.

Thursday-Friday... A mid to upper level ridge axis builds eastward
across the Gulf late week, stretching across central Florida by
Friday. At the surface, weak high pressure extends across the Gulf
and the central Atlantic. A period of hot and dry weather will
persist. High temperatures in the low to mid 90s Thursday warm
into the mid 90s areawide on Friday. Light southwest winds become
variable at times in vicinity of the surface ridge axis. Muggy
morning temperatures are forecast to range the mid 60s to low 70s.

Saturday-Tuesday... High pressure holds control through the extended
forecast. A period of above normal temperatures continues with no
mentionable rain chances. A Moderate HeatRisk is expected to
build Saturday and into early next week as afternoon highs peak in
the mid to upper 90s. A sagging surface boundary across the
southeast U.S. will increase moisture from Sunday onward
resulting in peak heat index values between 100-105. This level of
heat affects most individuals sensitive to heat, especially those
without effective cooling and/ or adequate hydration. Morning
temperatures remain mild, mostly in the upper 60s to low 70s.
