area forecast discussion
national weather service tampa bay ruskin fl
255 pm edt Sun jul 22 2018

Short term (Sunday night-Monday)
Currently levy county is under a severe thunderstorm watch
until 8pm. This is due to a strong troughing and an upper
level low sitting over the eastern half of the us causing
multiply short waves to be pushed down into florida. The
combination of the short waves plus very high instability in
the area will combine to support organized, strong, and
longer living updrafts which is the opposite of our
typically short lived plus storms we are use to during the
summer months.

Currently most of the robust activity is staying to our
north and east. Current hi-res models are showing this
activity could stay mostly to our east with only are most
northern areas will be influenced by this first round which
will be during the afternoon and early evening hours.

However, hi-res models like the hrrr and NAM 3km is showing
another shortwave forming in the panhandle and heading down
the west coast of florida late evening and into the
overnight hours. This will have to be monitored closely and
a watch will be possible later today.

Areas south of i-4 will see a few pop up showers today but
for the most part it looks like it will be a hot and muggy
day for the southern half of our area.

As we head into tomorrow we could see a line of showers
around i-4 working south and could be a soggy commute for
some of us. If this line holds together it will work its way
into our southern counties through the afternoon hours.

Besides the line of showers all of us will see a much better
chance to see some pop up showers and storms through the
afternoon and evening hours.

Long term (Monday night-Sunday)
Mid upper-level troughing over the southeast will finally lift out
Wednesday into Thursday as another broad trough swings across
southern canada. At the surface, low pressure over the region will
be replaced by an area of high pressure moving toward the eastern
seaboard. The subtropical ridge axis will also build back over the
southern florida peninsula. This overall pattern will keep a
southwest flow in place through much of the week, with a lighter
flow into the weekend. Scattered to numerous showers and
thunderstorms can be expected each day this coming week, starting
out over the gulf waters overnight and in the morning hours, then
migrating inland through the rest of the day. The lighter flow this
weekend will allow for a more typical summertime sea breeze pattern
to take shape.

Aviation
GenerallyVFR conditions will persist through the forecast
period. Most TAF sites will remain dry over the next few
hours. However some thunderstorm activity will start to pick
up around the evening hours. A shortwave moving through
will help to keep thunderstorm chances through the overnight
hours.

Marine
Westerly flow will continue between a broad area of low
pressure over the southeastern states and a ridge of high
pressure across the southern gulf of mexico. As the area of
low pressure sinks farther south towards the eastern gulf,
wind speeds will increase to around 20 knots, producing low
end advisory level conditions today. Cautionary to possibly
advisory level winds will continue into Monday afternoon
before gradually subsiding Monday night as the pressure
gradient relaxes. West winds around 15 knots or less will
continue through the rest of the week. Otherwise, higher
winds and seas will be possible in daily showers and
thunderstorms, producing locally hazardous marine
conditions.

Fire weather
Relative humidity will remain well above critical thresholds
though the forecast period.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
