746 am edt Sun may 20 2018

Aviation
Mainly MVFR or ifr conditions persist this morning across area
terminals with intermittentVFR. Numerous showers and a few
thunderstorms can be expected today with MVFR ifr CIGS and or vsbys
possible at just about any time.

Prev discussion issued 355 am edt Sun may 20 2018
short term (today-Monday)...

stagnant pattern persists with an u l trough over the
eastern gulf of mexico western caribbean and an u l ridge
northeast of the bahamas. W v imagery shows circulation
around both of these systems pulling deep tropical moisture
north from the itcz in atmospheric river like fashion across
the central caribbean and florida peninsula. This pattern
is expected to persist through Monday with pcpw values
across the forecast area around 2 inches which will
continue to create a threat for locally heavy rain each day.

Atmosphere remains conditionally unstable and weak surface
heating will generate numerous showers and isolated
thunderstorms each day. Extensive cloud cover shower
activity will keep MAX temps several degrees below climatic
normals with highs in the lower to mid 80s across west
central and southwest florida.

Due to the heavy rain over the past several days, there
have been significant rises on the alafia and little manatee
rivers. The alafia river will likely rise above flood stage
Sunday night, and any additional heavy rain across the
little manatee river basin could cause the little manatee to
rise to near flood stage in the next couple of days.

Long term (Tuesday - Saturday)...

throughout the extended forecast period, much of florida
will remain in a tropical airmass with ample moisture in
place each day setting the stage for daily showers and
thunderstorms. Placement of surface high pressure across the
western atlantic will keep a moist S SE in place in the
lower-levels. Subtle changes from day-to-day will have an
impact on daily pops but generally expecting scattered to
numerous thunderstorms. Late in the period, models continue
to differ on their handling of tropical moisture disturbance
moving out of the western caribbean. GFS appears to be an
easterly outlier compared to ECMWF and cmc but still plenty
of time to see how things will play out in the coming days.

As far as temps are concerned, generally expecting mid 80s
for highs with lower 70s overnight.

Aviation...

vfr CIGS this morning 100-120 with areas of MVFR cigs
010-020. Numerous showers and isolated thunderstorms will
develop today with LCL MVFR CIGS and ifr vsbys. Areas of
marginal MVFR CIGS will develop this afternoon 025-035.

Marine...

winds and seas are expected to remain below advisory levels
through the period. Main hazard will be showers and
thunderstorms which will be possible over the waters through
the remainder of the week. The stronger storms will be
capable of producing strong gusty winds, locally rough seas,
and heavy rain.

Fire weather...

no fire weather hazards are expected for the next several
days as relative humidity values are expected to remain well
above critical levels.
