Synopsis
Cool high pressure over the eastern carolinas will drift offshore
today, resulting in southerly flow that will bring warmer
temperatures into the area through Monday. Low pressure will cross
north carolina late Monday into Monday night, drawing a backdoor
cold front southeastward through the region and ushering in colder
temperatures for Tuesday.

Near term tonight
As of 235 am Sunday...

a freeze warning remains in effect for far SE sections of central nc
early this morning. Temps in these locations in which the
frost freeze program has been activated have already fallen into the
mid 30s in some spots.

Overall a quiet day is expected. A subtle wave aloft passing over
the southeast will bring a band of high thin clouds across the area
today, but the column remains dry and stable. Surface high pressure
will drift offshore today, allowing a slow uptick in dewpoints
through the day as light southerly flow takes over. Near normal
thicknesses this morning will climb above normal by day's end,
favoring highs from the upper 60s to lower 70s. High clouds will
increase and thicken further tonight as low pressure now located
near the ks NE border tracks through the mid miss valley and W ohio
valley, drawing higher pw (near 0.75") into nc. Don't expect
anything more than isolated sprinkles at most overnight, with weak
to absent lift and a dry subcloud layer. With skies trending to
partly to mostly cloudy, expect mild lows in the upper 40s to near
50. -gih

Short term Monday and Monday night
As of 300 am Sunday...

the mid level shortwave trough moving into the W ohio valley early
mon will dampen as it tracks SE toward and through the carolinas
through Mon night, but injection of additional energy from the
central plains into the lower miss valley will allow this system to
maintain decent forcing for ascent as it approaches. In addition to
the dpva and height falls, the backing of winds aloft ahead of this
wave will prompt an increase and deepening of moist upglide over nc
from the nw. As surface flow strengthens from the S and sw, the
increasing low level moisture (dewpoints pushing up through the 50s
to near 60) will contribute to marginal CAPE values of a few hundred
j kg Mon afternoon into the evening, within 30-35 kts of deep layer
bulk shear, supportive of a few thunderstorms as the corresponding
surface low crosses the area. Isolated showers in the morning will
increase in coverage by afternoon as moisture and lift strengthen,
so will bring pops up to likely, mainly in the W and N in the
afternoon before translating to the S and E with surface low
passage. As this pulls the attached cold front down through the
area, the low levels will stabilize quickly late Mon night, with
enough drying aloft for a transition from showers to patchy light
rain or drizzle post-front. NE surface winds will strengthen with
the tightening mslp gradient just behind the front, and some chilly
late-night gusts are likely. After warm highs Mon in the upper 60s
to mid 70s, despite the cloudiness, lows Mon night should be in the
upper 30s N to mid 40s s. -gih

Long term Tuesday through Saturday
As of 310 am Sunday...

very quiet weather for the vast majority of the long term. At the
onset, a cold front will be in the process of working through
central nc and while the northwest piedmont will be behind the front
by 12z Thursday, the southeastern half of the area will still have a
chance of mainly light rain lingering over the area through 18z or
so before an end to the rain and the beginning of some clearing
across the north as the colder, drier airmass moves in. This should
happen early enough that freezing temperatures will once again come
into play for Thursday night into Friday morning for the much of the
northwestern half of the cwa.

From Wednesday onward, dry conditions are expected as surface high
pressure noses in from the northeast and an upper level ridge moves
over the southeastern CONUS and strengthens through the week as it
becomes pinched between a low pressure system over the atlantic and
a deepening longwave upper trough over the western conus. Marginally
warmer temperatures on Wednesday afternoon with freezing temps
possible once again Wednesday night. By Thursday the surface high
shifts slightly eastward and the upper ridge moves directly overhead
helping afternoon highs gain 5-10 degrees over Wednesday and top off
in the low 60s. By Friday, the ridge really begins to strengthen as
its held nearly stationary and highs will jump again into the upper
60s to low 70s. Rinse and repeat for Saturday, tacking on another 5
degrees to gain the low to mid 70s.

Aviation 06z Saturday through Thursday
As of 1250 am Sunday...

confidence is high thatVFR conditions will hold for the next 24
hours over central nc, as high pressure over the area drifts slowly
e and offshore. We'll see nothing more than periods of high thin
clouds today, although clouds will steadily thicken with lowering
bases into the mid levels (6 000 to 12 000 ft agl) tonight. This
will occur ahead of a low pressure area, currently over the NE ks
border, that will cross the mid miss valley into ky tn through
tonight. But any CIGS will beVFR, with vsbys remainingVFR as well
through tonight.

Looking beyond 06z mon, a few sprinkles are possible over central nc
late tonight, mainly near int gso, butVFR conditions will hold. The
chance for showers will increase mon, peaking Mon afternoon and
evening. MVFR conditions may occur with these showers mon. Ifr lifr
conditions are possible Mon night as the low passes through and
drags a cold front SE through the area, producing chilly winds from
the NE into Tue morning.VFR conditions will return Tue afternoon,
lasting through Wed Thu as high pressure builds in from the n. -gih

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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.
