Area Forecast Discussion National Weather Service Key West FL 1032 AM EST Thu Mar 4 2021
DISCUSSION. Currently - A cool front moved through the Keys last night resulting in cooler and drier weather. After bottoming out in the mid to upper 60s, temperatures have climbed broadly into the upper 60s to near 70. Dew points have fallen to near 60 degrees. Winds are gentle to moderate out of the northwest due to high pressure centered along the central Gulf Coast and the tail end of a trough over the Bahamas. Skies have cleared out for portions of the island chain, however more stratocumulus lies upstream.
Short Term Update - Fairly cool northwest breezes will back a bit due to day time heating as well as the lingering trough off to the east. Expect some lulling on the western half of the Keys, while winds may pick up moderately late in the afternoon in the Upper Keys. Temperatures should climb into the lower 70s with dew points falling towards the mid 50s. Stable conditions will continue with virtually no chance for precipitation. However, patches of stratocumulus will stream across at least the western portion of the island chain.
MARINE. High pressure along the central Gulf Coast and the tail of a trough over the Bahamas will result in moderate west to northwest breezes across Keys waters this afternoon. Expect a minor lull to the west as Florida warms. Winds will lull near and south of the mainland, but mesoscale effects should result in a moderate surge late in the afternoon.
AVIATION. Occasional broken ceilings above 3000 feet may continue through early this afternoon, but VFR conditions are expected to prevail at the terminals through 05/12z. A prescribed burn continues at Cape Sable with gusty northerly winds bringing some of the smoke to KMTH. Temporary MVFR visibilities are possible in association with this smoke at KMTH, but not likely given the waning nature of the fire.
