Synopsis
Low pressure will track off the southern middle atlantic coast
tonight. A related back door cold front will surge southward across
central nc overnight, followed by the passage of a secondary cold
front that will cross the region early tue. Strong, continental
polar high pressure will follow and ridge southward across the
middle atlantic states through mid-week.

Near term through tonight
As of 435 pm...

a parent, positively-tilted shortwave trough over the oh valley this
afternoon will pivot ewd across the cntl appalachians overnight, to
the e-cntl carolinas by 12z tue. In fast cyclonic flow at the base
of that trough, a couple of strongly-sheared perturbations, well-
defined in WV satellite imagery from w-cntl al NRN ms, nwwd to nwrn
ar, will immediately precede the parent shortwave trough and track
ewd across ga, sc, and sern nc, then offshore, through the same
time.

At the surface, a 1013 mb frontal wave over cntl va, along a lead
synoptic front there, will migrate ewd and offshore the SRN middle
atlantic coast, while deepening several millibars, tonight. A 1012
mb pre-frontal, lee low analyzed over the NRN nc piedmont will fill
owing to diabatic cooling and pressure rises within an area of
showers coincident with that low. The cold front related to the
frontal wave will settle swd across cntl nc between 03-09z tue. A
secondary, polar front, analyzed at 20z from n-cntl nj wwd across s-
cntl pa, will follow and move swd across va tonight, and into cntl
nc early Tue (just beyond this forecast period).

While temperatures have warmed considerably into the 60s and 70s
today, instability remains weak across cntl nc this afternoon owing
to only modest low level moisture return into cntl nc. In fact,
surface dewpoints have risen only into the upr 40s to mid 50s today,
and have diurnally-mixed out slightly this afternoon. Nocturnal
cooling and continued limited moisture return suggests instability
will remain weak over cntl nc through tonight, bounded to the west
by a diffuse outflow boundary accompanying the area of showers now
encroaching from the NRN wrn nc piedmont. There will be a slight
chance of thunder to the east of the boundary for the next several
hours, but that probability appears low; the nearest lightning to
cntl nc remains INVOF atlanta and sern tn (in closer proximity to a
pocket of colder temperatures aloft related to the approaching
shortwave trough).

Showers, however, will become numerous to widespread through early
tonight, forced by the developing outflow circulation and
ana(outflow)frontal lift amidst steady (30-60 m) mid level height
falls forcing for ascent. Previously forecast quarter to half inch
rain totals remain on target. Showers will end from west to east and
become increasingly spotty overnight, as drying aloft occurs atop a
shallow, low overcast layer (between 1500-5000 ft) as the mid-upr
trough axis moves east. It will otherwise become breezy in strong
nely CAA overnight, as the foregoing frontal wave deepens while
tracking offshore, and pressure rises accompanying incoming high
pressure surge swd.

Short term Tuesday and Tuesday night
As of 355 pm Monday...

1030-1035 mb continental polar high pressure will build from the
great lakes to the NRN middle atlantic states, while ridging swd in
the lee of the appalachians, tue-tue night. This high will be led
swd by a secondary surface cold front, analyzed at 19z from long
island wwd across NRN nj and s-cntl pa, forecast to cross cntl nc
tue morning. Related CAA and nely breeze low level flow will yield
unseasonably cool temperatures mainly in the lwr-mid 50s, despite a
mostly sunny afternoon that will follow north to south clearing of
the preceding post-frontal band of stratocumulus.

A shortwave trough will dig from the cntl high plains this
afternoon, sewd and offshore the ga fl coast by Wed morning, with
associated cloudiness that will remain south of cntl nc. Skies will
consequently remain clear; and given the presence of the
aforementioned strong surface ridge, strong radiational cooling will
result. Freezing temperatures are consequently likely throughout
cntl nc overnight (26-32 degrees), down a few degrees from previous
forecasts. This will likely necessitate a progression of freeze
watches warnings in subsequent forecast issuances where the growing
season has officially begun, relative to the climatological median
date of the last spring freeze (ie. The ERN coastal plain and
sandhills).

Long term Wednesday through Monday
As of 335 pm Monday...

the upper level pattern at the start of start of the long term
period features a northwest flow aloft for the middle of the week
with cool high pressure extending southwestward into the region. A
shallow but chilly air mass will result in highs 10+ degrees below
normal on Wednesday. Decoupled winds with good radiational
conditions will result in frost and freeze conditions again on
Thursday morning with lows in the 29 to 35 degree range with the
coolest temperatures across the northeast.

The upper flow will become more westerly on Thursday into Friday
resulting in a moderating air mass and a slight increase in high
clouds. Highs on Thursday will range in the low to mid 60s with
highs in the lower 70s on Friday. Lows will range in the lower to
mid 40s on Friday morning.

A northern and southern stream trough will phase over the central
plains late Friday into Saturday with a southwesterly flow
developing across the carolinas. As the trough and the associated
cold front move east, deep layer moisture will increase on Saturday
into Sunday. The operational runs of the GFS and ec still show a
considerable spread in the timing, phasing and evolution of the
upper trough and the front with the GFS still about a day faster
than the ec. Accordingly, have spread chance pops across the area
beginning late Saturday night and primarily for Sunday and Sunday
night and then decreasing on Monday. Not terribly confident in how
things will evolve but it is probable that the actual period of rain
on Sunday and Monday is more limited than the breadth of the period
of pops.

Saturday is likely to be a warm day with highs well into the 70s to
around 80 in the sandhills. Have adjusted lows on Saturday night
upward with the approaching front, clouds and mixing. Highs on
Sunday will be complicated by the position of the front and the
associated precipitation, but for now have includes a range of the
mid 60s to mid 70s. Cooler air should arrive on Monday with highs in
the upper 50s to lower 60s. -blaes

Aviation 00 Tuesday through Saturday
As of 755 pm Monday...

showers with areas and periods of sub-vfr ceilings and visibilities
will continue across central through the evening hours as an area of
low pressure and associated frontal systems move across the area.

More widespread sub-vfr conditions with reduced ceilings will become
widespread after midnight and continue through daybreak. As drier
air moves in behind a complex frontal structure early Tuesday,
ceilings will improve and skies will clear from north to south
during the mid to late morning hours.

Light and mainly northwesterly winds this evening will increase and
become gusty as winds veer to northeasterly toward midnight and
after 06z in the south. Northeast winds at 10 to 15kts with gusts of
20 to 25kts are expected late tonight and Tuesday morning before
gradually relaxing during Tuesday afternoon.

Looking beyond the 24 hour TAF period: high pressure will extend and
build into the region through the first part of the weekend
resulting in fair weather and mainlyVFR conditions. -blaes
