454 AM EDT Fri Mar 24 2017
Showers and thunderstorms were mainly over the waters south of the
Florida Keys overnight and earlier this morning. Some of these
showers produced wind gusts of 25 to 30 knots. Temperatures were
able to drop to the low 70s degrees with dew points in the mid
60s. Outside the storms, winds were increasing over the area,
ranging 10 to 15 knots with gusts to 20 knots and near 20 knots
over the waters.
Some of the island communities of the Keys experienced showers
and thunderstorms last night. This was thanks to a front that
moved south from South Florida. A mid-level trough will still be
moving away from the peninsula this afternoon, which will aid in
the development of additional showers later this morning and early
afternoon. By tonight, a high pressure will extend into the local
area, allowing for the improvement of the weather conditions. The
pressure gradient will then start to loose it up on Saturday
morning and advisory headlines may not be neccesary for the
second half of the weekend. As this high pressure and its western
ridge settles into our area, winds will weaken and weather
conditions will return to mostly clear to partly cloudy skies,
temperatures near 80 during the day and lower 70s at night.
Winds from the east have been ranging near 20 knots with higher
gusts at the available marine stations along the Florida Keys
coastal waters this morning. Based on the latest model guidance,
winds will increase a few knots today and remain fresh to strong
today and slowly decrease on Saturday.
Scattered showers may bring brief MVFR conditions to the KEYW and
KMTH terminals this morning. That probability has been TEMPOed at
both locations early this morning, and may need to be extended to
or slightly beyond 10z. Otherwise, expect VFR conditions at the
island terminals through late this evening. Winds will become more
uniformly from the east, sustained close to 15 knots by early
afternoon with frequent gusts AOA 20 knots.
On this date in 1983, 1.18 inches of rain was measured in Key West.
This set the daily rainfall record for March 24th in the city.
Rainfall records for Key West date back to 1871.
