Marine Weather and Tides
Greenbriar, FL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

area forecast discussion
national weather service tampa bay ruskin fl
301 pm edt Thu may 24 2018

Short term (tonight-Friday)
High pressure ridging across the area will weaken through
Friday as an area of low pressure over the NW caribbean
begins to move north into the yucatan channel. Moist and
unstable tropical air remains in place across the area
through the period, with afternoon shower and thunderstorm
activity diminishing for the overnight hours, and then
returning across the area late Friday morning through Friday
afternoon. Lows tonight expected in the lower to mid 70s.

Highs Friday generally in the mid to upper 80s. Will
continue to monitor the possible tropical development of the
area of low pressure for weekend impacts here.

Long term (Friday night-Thursday)
The main forecast concern for the end of the week into the
weekend continues to be the tropical disturbance currently
located near the yucatan peninsula. The national hurricane
center has increased the chance of development to 70% within
the next 2 days and 90% within the next 5 days. There are
some minor model differences in the eventual track and
timing, but generally expect this system to move into the
central or eastern gulf of mexico on Saturday, continuing to
drift northward toward the northern gulf coast region
Saturday night into Sunday. Global models then stall this
feature through Tuesday.

The overall forecast thinking has not changed much, as a
deep southeast to south flow will keep abundant tropical
moisture over the state through the weekend. We are still
expecting widespread 3-5 inch rainfall totals through this
event, with locally higher amounts certainly possible. In
addition to the heavy rainfall, saturated soils will
exacerbate the flooding concerns. Area rivers remain below
flood stage this afternoon, but again, additional rainfall
will likely lead to some minor flooding on several streams
and rivers. If this system tracks farther westward than
currently forecast, rainfall totals will likely be lower.

Once this system washes out, we will still be looking at
remnant tropical moisture over the region, so scattered
showers and thunderstorms will remain in the forecast
through Thursday.

Aviation
Showers and thunderstorms are starting to develop over the
southern terminals this afternoon and will spread across the
rest of the area over the next couple of hours. A weak sea
breeze is expected near the coast of the northern
terminals, otherwise light E SE flow will prevail through
the period. Thunderstorms diminish after 01z, with skies
clearing some overnight, then chances returning late Friday
morning.

Marine
Light E SE winds through the end of the week with likely
showers and thunderstorms. Winds and seas higher near the
storms. Then will be monitoring an area of low pressure lift
northward from the yucatan channel area for possible
tropical development. At this time, it looks like the local
impacts from this are to raise winds, especially over the
offshore waters, to SCA levels, with possible gale force
gusts and showers and thunderstorms continuing. High
pressure will then build back in across the waters from the
atlantic for early next week.

Fire weather
No concerns.
