Update Extensive mid and upper level cloudiness is helping to
limit the temperature drop this evening, despite already calm light
across the region. Dewpoints remain in the upper 50s and 60s,
which will keep overnight lows mild and somewhat muggy in the
mid- upper 50s over the interior and gulf coast to low-mid 60s
along the east coast. The cloudiness puts the degree of fog
development somewhat in question, but at least patchy development
still looks like a good bet over the interior. No significant
changes to the ongoing forecast.

high pressure centered northeast of the region will keep east wind
in place through early next week. Wind of 10 kt will diminish to
aob 5 kt overnight, then 10 to 15 Sunday.VFR conditions prevail
with generally ci cs CIGS with sct to at times bkn 4-6kft clouds.

Interior fog possible but should stay inland of tmb and apf.

Prev discussion... Issued 348 pm est Sat jan 20 2018
discussion...

this afternoon and tonight: 90-100kt jet crossing the state this
afternoon continues to produce an extensive area of mid and upper
level cloudiness that looks to linger through tonight.

Morning sounding shows atmosphere is well capped at around 4kft, and
overall not very moist. As the upper level shortwave approaches from
the west late tonight, slightly better instability may be enough to
squeeze a few sprinkles light showers out of the mid level deck.

This threat is too low however, to mention any precip in the
forecast.

Warming trend will continue with mild overnight lows ranging from
the mid-upper 50s over the interior and gulf coast to low-mid 60s
along the east coast. Warmer temps and dewpoints will also bring the
threat for patchy fog, mainly over the interior.

Sunday: the upper level shortwave moving long the northern gulf
coast will cross the state during the day on Sunday. Models continue
to trend drier for south florida, as we will be in between the
deeper moisture that the shortwave itself brings and the weak
boundary well to our south. This lack of deep moisture will limit
the opportunity to take advantage of the shortwave and weak
isentropic lift associated with it. The result is a mostly dry
forecast, with the best opportunity for showers over the atlantic
and across miami-dade. The potential for sprinkles will exist
across all of south florida.

Monday through Friday: strong upper level low and surface low make
their way through the the great lakes upper midwest on Monday, with
an accompanying frontal boundary trailing through the deep south.

Main system remains well north as it moves into the northeastern us,
with just enough energy further south to allow the frontal boundary
to somewhat limp into the state on Tuesday.

The ECMWF is more robust with precip chances as the boundary moves
in, with the GFS barely bringing any precip. The GFS also has the
boundary washing out more quickly by Tuesday night with flow
becoming ene as the surface high building behind it overtakes it.

The current forecast follows a consensus of the two, which brings
the best chance of showers Tuesday Tuesday night, with a threat
lingering into Wednesday.

While the models differ on exactly where the front stalls out, the
consensus is for deeper low level moisture to linger across or just
south of the area late week. The increasing pressure gradient will
bring breezy ene flow, which is a fairly good signal for scattered
showers moving across the area from the atlantic.

Marine... High pressure will remain to the north of the region
through Monday. Moderate ene winds will continue into tonight,
veering more easterly on Sunday and Monday. Gradient will support
periods of 15-20kts at times, especially on Sunday as an upper level
system crosses the region. Seas will continue to diminish, but will
remain choppy over the local atlantic. Boaters should exercise
caution into Sunday.

Flow becomes light and variable on Tuesday as a front moves into the
peninsula and washes out, with moderate to strong east-northeast
winds re-establishing behind the boundary mid to late week. The
approach of the front will also bring a return of shower chances to
the region for most of the upcoming week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
