Area Forecast Discussion
National Weather Service Tampa Bay Ruskin FL
929 AM EDT Tue May 14 2024
...New UPDATE...
.UPDATE...
Issued at 925 AM EDT Tue May 14 2024
A narrow line of storms is moving across north FL and portions of
the Nature Coast, which has fortunately remained sub-severe this
morning so far despite the favorable dynamics in place as well as
moderate instability. Meanwhile, there is a larger cluster of
storms offshore that has been moving ENE across the Gulf waters
and recent satellite imagery shows cloud tops colder than -60C
associated with this activity. Thus, this next wave of convection
offshore may pose another severe risk but there remains uncertainty
with how this cluster holds together as it gets closer to the
coast. Given the favorable environment in place, will maintain
the ongoing tornado watch for our northern counties and adjacent
nearshore waters but will continue to keep a close watch on the
convection offshore as it continues to approach our area.
&&
.DISCUSSION...
Issued at 233 AM EDT Tue May 14 2024
An active weather pattern continues as multiple rounds of showers
and storms move through the area. Another MCS will slide across the
northern Gulf and will likely be impacting our northern waters by
morning. Current models are keeping the bulk of the convection
with this round of storms mainly north of I4. However with the
current dynamic setup, some storms could be severe with hail,
damaging winds and a possible tornado. SPC currently has areas
south to Sarasota county in a slight risk with the remaining areas
of the CWA in a marginal risk.
Meanwhile as the MCS moves through today, an upper level trough
continues to move across the Mississippi valley. The cold front
associated with the trough will bring another round of showers and
storms to our area beginning tonight and into tomorrow. Once again
with increased instability, 500mb temps around -9/-10C, and a strong
westerly flow, severe storms could be possible. Thus SPC, has placed
the middle of the peninsula in a marginal risk. Primary threats will
be hail and damaging winds.
Though ridging builds back over the area by the end of the week,
enough moisture will be available that, rain chances remain in
the forecast. By the weekend another cold front approaches the
area bringing another round of convection. Hopefully with the
multiple rounds of rain and storms, everyone's grass will once
again be green.

.AVIATION...
(12Z TAFS)
Issued at 738 AM EDT Tue May 14 2024
Patchy MVFR CIGs this morning before mostly VFR conditions
through the early afternoon hours, though flight conditions may
deteriorate afterwards as a cluster of storms offshore approaches
the area. There remains uncertainty with this activity and overall
impacts but greatest precip chances will occur at Tampa Bay area
terminals where VCTS has been added to KTPA/KPIE for possible
restrictions. A lull in activity will occur tonight but another
round of storms will move across the area Wednesday morning with
additional restrictions possible.
&&
.MARINE...
Issued at 233 AM EDT Tue May 14 2024
Multiple rounds of showers and thunderstorms will begin to impact
waters this morning. Primary concerns will be strong winds,
isolated waterspouts, frequent lightning and heavy rain. Winds
will also increase ahead of these lines calling for Small Craft
Should Exercise Caution headlines for most areas.
&&
.FIRE WEATHER...
Issued at 233 AM EDT Tue May 14 2024
An increase in moisture has helped RH values remain above critical
levels for most areas, however they could dip down for areas that
are left out of the rainfall. Several rounds of
showers/thunderstorms expected through Wednesday.
