DISCUSSION

A weak ridge stretching across South Florida this evening is driving in light mostly east to southeasterly breezes across the Keys area. Weak deep layered ridging is roughly aligned across our area. Despite this, this evenings sounding indicated the precipitable water was very close to the median for the day at 1.84 inches. There was a some drier air and limited CAPE through the lower levels. This and a lackluster forcing has kept shower and thunderstorm activity quite limited through the evening. Surface conditions are seasonably warm but unusually dry. Dew points were near 70 for much of the late afternoon and early evening, but been climbing in recent hours into the mid 70s.

The ridge across Florida will lift slightly northward into Central Florida overnight. This along with dissipating day time heating effects will let breezes firm up slightly out of the east to southeast across the area. Forecast soundings suggest that the lower levels may moisten slightly while becoming a bit less stable. This along with the usual enhanced nocturnal confluence may be enough to trigger a few convective cells later in the night. If winds remain light across the Keys, temperatures may be able to radiate down into the lower 80s with dew points continuing to recover into the mid to upper 70s. No changes planned this evening.
