800 pm est Thu jan 18 2018

Update Winds diminished quickly around sunset, which allowed
for a relatively quick drop in temperatures that has steadied out
late this evening. Fairly dense cirrus deck looks to continue to
stream overhead tonight, which is expected to prevent any
dramatic temperature drops overnight. However, another chilly
night is still expected with low ranging from the mid 30s across
glades and hendry, to the upper 30s and low 40s for the remainder
of the interior and gulf coast, and upper 40s low 50s for the east
coast metro. While can't rule out a few of the coldest spots over
the NW interior touching freezing, a widespread or prolonged
freeze looks unlikely. Frost will be a concern across interior
collier, hendry, and glades counties.

No significant changes to the ongoing forecast.

Prev discussion issued 628 pm est Thu jan 18 2018
aviation... Winds quickly diminishing and becoming NW along east
coast this evening, continuing NE at kapf. Speeds generally
dropping to 5-8kts through the remainder of the overnight. Winds
veer NE or ene 8-10kts along east coast after 15z-16z, which will
bring additional clouds fl030-050 over the coast. Overall cigs
expected to remainVFR. May be a few sprinkles, but no
significant precip expected at this time.

Prev discussion... Issued 338 pm est Thu jan 18 2018
discussion...

temperatures warmed up into the low 60s this afternoon for most of
the east coast metro area. Tonight, good radiational cooling and
lighter winds will allow for significant cooling, although the
lows tonight won't be quite as cold as last night. Lighter flow
will also allow winds to decouple which could allow frost to form
tonight over portions of inland southwest florida, particularly
glades and hendry counties away from the influence of the lake.

While frost is likely to form in wind protected areas, we do not
think there will be widespread frost. Thus, opted not to issue
frost advisory. Temperatures will get down to the mid 30s west of
the lake, but still think most areas should escape another freeze
threat and wind chill concerns should be minimized by the lighter
wind expected overnight.

On Friday, surface high pressure building over the southeast conus
will help veer winds across south florida to the northeasterly
direction. As is often the case, this flow pattern should modify
the airmass by bringing in deeper lower level moisture from over
the atlantic. On Saturday, a weak transient ridge should help
maximum and minimum temperatures rise to near seasonal averages.

Precipitation chances begin to creep higher as well, with deeper
moisture increasing from the south. Both the GFS and ECMWF agree
in drifting a weak upper-level low pressure disturbance eastward
across the northeastern gulf or southeast u.S. Saturday night into
Sunday, which will help to create a chance for showers. However,
rain chances won't be terribly high (not more than 25-30 percent)
because a surface ridge will be located nearly directly beneath
the upper-level low. Rain chances around 30 percent give or take
could stick around for much of next week as a few weak
disturbances keep enhanced moisture over the area. There do not
appear to be any strong cold fronts over the next 7 days that
would cause a major dip in temperatures, although a weak cold
front cannot be ruled out around the middle of next week.

Marine... Gusty north winds will shift to northeast tonight, and
gradually weaken late tonight into early Friday. The small craft
advisory remains in effect for the atlantic waters and has been
extended through 09z Friday.
