New DISCUSSION, AVIATION, MARINE, FIRE WEATHER
DISCUSSION
Issued at 119 AM EDT Fri Apr 18 2025 High pressure surface and aloft will build over the forecast area today...and will hold over the region through early next week. As heights build today, temperatures will increase a few degrees...with daytime highs generally in the upper 80s to around 90, and overnight lows in the upper 50s north...lower to mid 60s central and south. Daily temperatures will be in this range through Monday. The strong large scale subsidence over the area will create mostly sunny days and mostly clear skies at night.
The middle of next week, heights will lower a bit...however, high pressure will remain in control with continued mostly clear skies and daytime temperatures a degree or two lower, but they will continue to run several degrees above climatic normals.
AVIATION
(06Z TAFS)
Issued at 119 AM EDT Fri Apr 18 2025 VFR conditions are expected for the next 24 hours with clear skies through the early morning hours, with FEW040 SCT250 developing at most all terminals this afternoon.
MARINE
Issued at 119 AM EDT Fri Apr 18 2025 High pressure will hold over the waters through the period with winds remaining below cautionary levels each day. An easterly evening surge of wind will elevate winds for several hours each night, but again are expected to remain below cautionary levels.
FIRE WEATHER
Issued at 119 AM EDT Fri Apr 18 2025 Although minimum afternoon relative humidity values will tick up a bit today from previous days, they will still run near critical levels across much of west central and southwest Florida this afternoon. Winds are expected to remain less than 15 MPH which will preclude Red Flag conditions, however, the fire danger will be elevated. Similar conditions are expected during the afternoon hours for the next several days.
