area forecast discussion
national weather service tampa bay ruskin fl
309 am est Fri jan 19 2018

Short term (today and Saturday)
Broad upper level southwesterly flow has overspread the
region this morning in response to an upstream shortwave
trough over texas. This has lead to some scattered high
clouds over primarily the southern peninsula. At the
surface, a cold arctic high pressure center is slowly moving
eastward along the northern gulf coast.

This morning presents a somewhat complex forecast. While
freezing temperatures have been observed in areas north of
tampa bay, residual low level moisture from earlier onshore
flow remains near the coast, and dewpoints remain in the low
to mid 30s in some areas well inland. With light northerly
flow, some drying should occur through sunrise and will
maintain existing freeze and hard freeze warnings, though
actual freezing temperatures will likely be more spotty
south of i-4. As slight moistening has occurred since this
time yesterday, frost will be a possibility this morning,
especially north of tampa bay. Keep those ice scrapers
handy!
after sunrise, temperatures should warm up rather quickly
with highs rising into the 60s most areas. A few low 70
degree readings may occur further south around lee and
charlotte counties. Scattered cloudiness will gradually
increase from the south as southwest upper level flow
transports mid and upper level moisture into the region.

As the surface high continues to shift eastward tonight,
flow will become more easterly, resulting in increasing
moisture. This should prevent temperatures from getting
quite as low, but a few locations over the nature coast
could still briefly fall to around freezing by early
Saturday morning. As confidence in a widespread freeze is
very low, no watches will be issued at this time.

The temperature trend will continue in a positive direction
with highs from the mid 60s to lower 70s, a fantastic way
to start the weekend! Cloud cover will be on the rise as a
shortwave trough moves into the gulf of mexico, allowing mid
and upper moisture to continue streaming into the region.

Mid long term (Saturday night through Friday)
Seasonal temps expected to end the weekend with mostly rain
free conditions once again. An isolated shower or two cant
be ruled out across southern zones as low-level moisture
increases throughout the day but pops are limited to 20
percent. Frontal system looks to approach the area late
Monday and out ahead of it winds will become more southerly
allowing temps to push above climatological norms, with
upper 70s to around 80 expected for highs. The front will
push through on Tuesday with limited moisture (20-30 pops).

Wind flow shifts to northerly behind the front gradually
becoming northeasterly with temps cooling a bit but staying
near normal. On Wednesday and Thursday, models continue to
differ greatly on sensible weather across the area. For now,
will maintain chance pops until greater continuity exists.

Temps will continue near normal.

Aviation (06z tafs)
Vfr conditions with mostly clear skies. Light northeast
winds to shift to the northwest this afternoon for terminals
near the coast, then back to the northeast by 00z.

Marine
Northeast winds will become more easterly later today into
tonight as high pressure slips north of the waters. Winds
will generally remain 10 to 15 knots or less through the
weekend with favorable boating conditions. A cold front
looks to approach the region late Monday into Tuesday,
bringing the potential for sea fog ahead of the front, and
breezy north winds behind it. Thereafter, winds look to
remain elevated with strong high pressure building in north
of the waters and periods of cautionary to possibly advisory
conditions.

Fire weather
As very dry air remains in place today and temperatures
come in warmer than yesterday, expect critically low
humidities once again. However ercs remain too low and winds
too light to warrant any fire weather products. A rapid
moistening will occur tonight into the weekend as easterly
flow brings atlantic moisture into the region. This will
prevent any fire weather concerns heading into next week.

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.
