Area Forecast Discussion
National Weather Service Key West FL
242 PM EDT Fri May 26 2017

.DISCUSSION...
.CURRENTLY...
Local radars and visible satellite photographs show several
segmented, but shallow cloud lines along the Florida Keys. Within
this lengthy and emaciated boundary, a few light showers are being
seen in the Lower Keys. Temperatures are averaging in the upper
80s to near 90 degrees with light and variable winds. Surface
wise, a broad ridge axis is covering most of the Florida peninsula
and our region, resulting in variable winds of 5 to 10 knots on
our marine district.

&&

.SHORT TERM...(Tonight through Monday night)
For this holiday weekend, it appears the best chance for any
shower or possible thunderstorm activity will be associated with
wet cloud line genesis this afternoon into early tonight, and then
some activity dropping off the south Florida mainland late
Saturday afternoon and evening. Otherwise, extremely dry air will
filter into our area Sunday into Memorial day. Hence, isolated 20
percent pops will be sliced to dime pops beginning Sunday. High
temperatures will average near 90 with overnight lows near 80
degrees away from any isolated downpours.

&&

.LONG TERM...(Tuesday through Friday)
Little change in previous thinking with unusually dry air above
850 mb prevailing for most of this period. Without any discernible
low level perturbations expected, isolated 10 to 20 percent pops
seem on track. Plenty of intense insolation will allow high
temperatures to average near 90 with overnight lows generally
around 80 degrees.

&&

.MARINE...
Away from any showers or possible thunderstorms, light to gentle
winds will prevail on Keys coastal waters for most of this
weekend, before gradually increasing next week.

&&

.AVIATION...
Outside of a brief MVFR encounter or two, VFR conditions will
predominate at the Key West and Marathon terminals. Light and
variable winds at less than 10 knots can be anticipated at the
island airports.

&&

.CLIMATE...
In 1992, the daily record low temperature of 68 degrees was
recorded in Key West. Temperature records have been kept since
1872.

&&

.PRELIMINARY POINT TEMPS/POPS...
Key West 81 88 82 87 / 30 20 10 10
Marathon 81 91 82 91 / 30 20 10 10
