DISCUSSION

Issued at 1030 PM EDT Tue Mar 10 2026

Deep layered ridging remains in place across the broader area with a sharp mid to upper level ridge stretching northeastward across the Gulf. At the surface, an Atlantic high extends a robust ridge westward across the Florida Peninsula and across the Gulf. This surface ridge is supporting moderate east to southeasterly breezes across the Keys. Consequently, conditions are warm with temperatures in the mid to upper 70s and dew points near 70. This evenings sounding indicated middling precipitable water with a sliver of inhibition below 900 mb. This, along with little to no lifting, has kept shower activity minimal across the forecast area through the evening hours.

Expect ridging to continue to dominate the region through the night. Expect gentle to moderate east to southeasterly breezes to hold up overnight lows in the mid 70s. Dew points will meander near 70. Rain chances will remain slim to none. No update planned for the ongoing local forecast.
