National Weather Service Key West FL
1041 PM EDT Thu Apr 19 2018

Data from the Key West evening radiosonde balloon indicated a very
dry and stable air mass aloft. Satellite and surface observations
indicate transient cirrus, with no precipitation echoes detected
by Key West Doppler radar. Currently, air temperatures in most
Keys island communities are holding steady in the mid 70s, with
dewpoint temperatures in the mid 60s. Winds range from light north
to light and variable.

A warm and mild overnight is expected with passing cirrus and
light winds. No updates needed.

No watches, warnings, or advisories are in effect for Florida Keys
coastal waters. A ridge of high pressure will move away to the
east tonight. A trough of low pressure will move southward across
the Florida Peninsula and eastern Gulf of Mexico, before
dissipating near the Florida keys on Friday. Thereafter, a high
pressure area over the eastern United States will shift over the
western North Atlantic Ocean.

Through 20/24Z, prevailing VFR conditions are expected at both EYW
and MTH.

On this date in Keys Weather History, in 1934, a high temperature of
89 degrees was recorded in Key West. This set the daily record for
warmest high temperature for April 19th in the city. Temperature
records in Key West date back to 1872.
