DISCUSSION. Water vapor imagery show upper-level lows spinning in the western Gulf and over the eastern tip of Cuba. Another weak low pressure is still sitting off the coast of the FL/GA state line and is expected to move inland over the next few hours. Ridging is currently trying to build back in from the east as this low moves inland, which is helping to support gentle to light southeast to south breezes across the Florida Keys and surrounding coastal waters. Shower activity has remained isolated and showers have been struggling to build. Little thunder has been observed so far today, indicating that most showers have remained relatively shallow. A similar environment looks to hang around overnight tonight, so isolated to scattered showers will likely continue after a lull this afternoon.
As ridging continues to build back into the area, our winds will remain from the southeast to south before taking on more of an east to southeasterly direction by mid week. Winds will be light and variable at times. Looking aloft, a TUTT cell currently over the eastern tip of Cuba will trek across the length of the island and move into the Straits of Florida early on Wednesday. Currently, there is very little convective activity associated with this feature and forecast soundings actually show drier air moving in around the time when the TUTT cell makes its closest approach to the Keys on Tuesday night through Wednesday night, so have nudged PoPs down. No other features of note look to move through the area through the extended forecast, so mesoscale processes will likely dominate our weather. With light flow, cloud line development is possible over the next week, so have retained near climatology rain chances (20-30%). Temperatures will remain near normal through the forecast period, with highs generally near 90 degrees and lows near 80 degrees. A fairly typical July week weather-wise is ahead for the Florida Keys.
MARINE. There are no watches, warnings, or advisories are in effect for the Florida Keys coastal waters. From synopsis, Low pressure centered east of north Florida will move inland over the the coast of northeast Florida or Georgia this evening. This will allow a ridge over the central Atlantic to build across the Florida Keys and South Florida throughout the week. Generally southeast gentle to occasionally moderate breezes and near-normal rain and thunder chances are expected.
AVIATION. VFR conditions will prevail at both island terminals through 18z Tuesday afternoon. While there may be episodes of isolated shower or thunderstorm activity, confidence in timing or impacts is far too low to include mention of VCSH at this time. Near-surface winds will generally be from the southeast to south at 5 to 7 knots.
CLIMATE. On this day in 2007, the daily record warm low temperature of 87F was recorded. This is the warmest low temperature ever recorded in Key West in July and ties the warmest low temperature ever recorded in Key West. Temperature records date back to 1872.
