It has remained mostly quiet across the region this afternoon. The only exception was up in the Upper Keys where a lone thunderstorm managed to produce a waterspout over the Hawk Channel waters briefly. Otherwise, aside from a few traces of precipitation here and there across the Florida Keys, it has been dry but cloudy. Despite the cloud cover, the southeast to south winds have allowed for temperatures to reach into the mid to even a few upper 80s.

The reason for the lack of precipitation today has been because of two key important factors. The first being that the mid level trough shifted northward, taking with it the best lifting mechanisms. Second, the lower levels saw an increase in relatively dry air. This in turn hampered convection development and most of the precipitation that attempted to fall wound up evaporating before reaching the surface.

Meanwhile, ridging that is centered out across the western Atlantic, will continue to building westward across the Florida Keys. As it builds in across the region, expect period of breezy conditions along the island chain and surrounding waters. In addition, there is more dry air pivoting northwestward from the Caribbean that will limit Probability of Precipitation through the weekend.

By Monday, moisture will surge across the area as deep easterly winds develop. This will allow for Probability of Precipitation to increase to near or slightly above normal for the extend forecast. Winds will peak and lull at times through the same time period. Temperatures through the next 7 days will hold steady with daytime highs in the mid to upper 80s and overnight lows in the upper 70s to near 80.

Marine
Gentle to moderate southeast breezes prevail this afternoon and freshen slightly tonight as ridging to our east continues to build. A period of moderate to fresh breezes will be possible across the Straits of Florida overnight. As such Small Craft Exercise Caution headlines are in effect for these waters. Otherwise, breezes will freshen slightly that a greater coverage of moderate to fresh breezes is expected Saturday and Saturday night. Thereafter, expect peaks and lulls as the ridge flexes across the region.

Climate
On this day in Keys weather history In 1932, the daily record rainfall of 3.83" was recorded at Key West International Airport. Rainfall records date back to 1871 at Key West.
