Synopsis
High pressure builds in from the west tonight through Friday
night, then moves offshore Saturday. A low pressure system
impacts the region Saturday night and Sunday. High pressure
returns Monday through Tuesday. Another low moves into the
region for Tuesday night and Wednesday.

Near term until 6 am Friday morning
A cold frontal boundary will move through the region early this
evening. Gusts will be limited both ahead of the front and in
the cold advection behind the front as winds aloft will remain
rather weather, 20-25kt, and the cold advection will not be too
strong. Also, little moisture was with the front, so few if any
clouds will be associated with the passage.

The sub tropical high will remain off the southeast coast at
least through tonight, and even through Friday night. At the mid
and upper levels near zonal flow will begin to become
northwesterly as ridging builds into the central united states.

Increasing subsidence and dry mid and lower levels will limit
clouds, with only thin high cloudiness possible tonight. Winds
may decouple late overnight and the normally colder areas may
end up several degrees lower than currently forecast.

Short term 6 am Friday morning through Friday night
The sub tropical high will remain anchored off the southeastern
coast through the period with a building ridge moving into the
eastern states and eastern canada through Friday night. By early
Saturday morning the ridge axis is still expected to remain to
the west of the region. Much of the time will be nearly cloud
free as subsidence increases, with only high clouds expected.

Long term Saturday through Thursday
Deep layer ridging gradually shifts eastward on Saturday ahead
of an approaching short wave. Deterministic models tend to
struggle with ridges of this strength, often showing too quick
of a break down eastward progression. As expected, the latest
model runs have slowed the progression of the high eastward
ahead of the approaching short wave, which in turn has delayed
the onset of precipitation for Saturday into Saturday night. The
main question initially will be how much cold air is able to
remain across the interior as the surface high moves offshore
and a warm front slowly approaches overnight. There may be at
least a few hours overnight as surface temperatures remain near
freezing for ice pellets and perhaps a light coating of freezing
rain as warm advection strengthens aloft. A non-diurnal trend
will occur though, with surface temperatures steadily rising
through the morning, effectively ending any threat of frozen
precipitation by the morning commute.

By Sunday, the area will be firmly in the warm sector with the
warm front to the north. Temperatures will be well above normal.

Trended slightly higher than guidance across areas to the north
and west of the city where s-sw flow will be predominant.

Otherwise, expect a period of heavy rainfall as deep layer
moisture rapidly increases through the morning, with pwat values
near the upper percentile values for time of year. There is
potential for a rumble of thunder too as colder temperatures
aloft associated with the short wave lead to elevated
instability, which may locally enhance rainfall rates. Refer to
the hydrology section for more information. By afternoon, a dry
slot aloft develops, with rain rates decreasing from west to
east, though light drizzle or rain will still be possible,
especially as the cold front moves through later in the day.

With cyclonic flow remaining and a strong short wave expected to
merge with the departing system, another secondary cold front
is expected to move through Sunday night, with a chance for
showers and snow showers.

Outside of aforementioned rain, there will be a significant
strengthening in winds as the system begins to depart, and cold
advection strengthens Sunday night into Monday night. At the
very least a wind advisory may be needed, though there is
potential for a few hours of winds bordering on high wind -
sustained 40 mph with gusts close to 58 mph, especially across
the east end with the departing low level jet Monday morning.

Thereafter, the northern stream becomes more dominant, with a
series of quick clipper systems possible, though timing and
placement remains uncertain. Temperatures are expected to settle
closer to climatological normals during that time frame.

Aviation 21z Thursday through Tuesday
High pressure then slowly builds in from the west overnight.

Vfr through the period.

West winds decrease to 10 kt or less this evening. Winds turn to the
nw late tonight and Friday and should remain just right of 310
magnetic throughout much of the day.
