KEY MESSAGES

- Strong high pressure over Bermuda will remain stationary through the weekend, supporting an extended period of relatively unremarkable weather. - Moderate to fresh breezes will wax and wane through the weekend, generally peaking during the overnight hours and lulling in the afternoons. - Moderate drought continues for the entire island chain. Burn bans are possible, trees and bushes begin browning, and water supply decreases. For the upcoming week, there will be a slight chance for showers.

FORECAST

High pressure centered over Bermuda will remain the main driver for the Florida Keys sensible weather for the next several days. The western side of this ridge extends over Florida and into the Gulf. This continue to promote moderate to fresh mainly easterly breezes through the weekend. Therefore, the prolonged breezy stretch for the Island Chain is expected to continue through at least Sunday before we notice a slight weakening in the high to allow breezes to fall below breezy conditions. Low-level moisture will remain ample with episodic showers remaining possible through the period. Temperatures will remain slightly above normal for the next week with daytime highs in the lower 80s and overnight lows in the lower to mid 70s. Also, early to mid next week, a slight strengthening to aforementioned ridge will potentially lend to another period of breezy conditions.

Looking ahead at the extended, late next week, there are signals a cold front will potentially try and press southward along the Florida Peninsula. However, there remains much uncertainty as to the intensity and if this front will indeed press through the Keys or stall nearby. More comfortable and less humid air might not be done just yet across the Keys. However, as we continue to move deeper into the spring months, it gets tougher for fronts to make it through the Keys. Stay tuned!
