FORECAST

Winter will continue across the Keys through the remainder of the week. High pressure will dominate the pattern today and tonight. This will keep breezes light to gentle this morning with breezes continuing to gradually slacken through tonight as high pressure slowly weakens across the area. Breezes may also become light and variable for a time overnight. Moisture remains meager at best resulting in nil to near nil rain chances today and tonight. However, slightly deeper moisture may result in a few isolated showers across the Straits of Florida. Temperatures remain below average with highs at best reaching the mid to upper 60s. Overnight lows won't fall too much from daytime highs remaining in the lower 60s to near 60 degrees. Humidity will also slowly climb today and tonight.

Another cold front, in association with a low pressure system across the Mid-Atlantic area, will slide southeastward Thursday. Moisture will pool resulting in chances of showers ahead of the front. The best chances for showers will be across the offshore Gulf waters and the Straits of Florida, though, a few showers cannot be completely ruled out for the Island Chain. The cold front is expected to pass through the Keys sometime later in the day Thursday or Thursday evening. This will result in rapidly freshening west to northwest breezes. Get ready for another blow and a return to colder and windy conditions. Highs Thursday will only manage to reach the upper 60s, potentially 70 degrees. Overnight lows tumble into the mid to upper 40s for the Upper Keys with 50 to 55 degrees for the Middle and Upper Keys. Dry air will filter in behind the front resulting in nil rain chances for Thursday night.

In the wake of the front, surface high pressure is expected to dominate the pattern for late week through the weekend and into early next week. Moisture remains scarce resulting in near nil rain chances through the extended. Breezes will modestly slacken Friday and Friday night with light to gentle breezes prevailing through the period along the Island Chain. Temperatures will slowly moderate each day through the extended, though, we wont fully get back to average till perhaps the middle of next week. Humidity will also slowly creep up each day though still remaining quite comfortable.
