Synopsis
A ridge of high pressure will extend across the eastern united
states through the weekend.

Near term through tonight
As of 1015 am Friday...

stacked high pressure over the deep south tn valley will maintain
dry and seasonably mild air mass over central nc this afternoon and
tonight. The circulation around this high pressure system is
resulting in a NW flow over our area. The downslope component of the
low level flow along with modest compressional warming aloft will
lend to a relatively warm afternoon with temperatures well into the
70s, and likely reaching 80 degrees across the southern piedmont and
the sandhills.

Presence of the low level dry air over the region will once again
allow temperatures to cool quickly immediately after sunset, falling
through the 60s in the early evening, and into the 50s by late
evening. Overnight low temperatures in the 45-50 degree range.

Short term Saturday and Saturday night
As of 350 am Friday...

mid-upper ridging will linger in the vicinity of the sern us coast,
while high pressure drifts off the middle atlantic and northeast
coast, while also strengthening. The result will be a generally
persistence forecast, though with an increase in high cloudiness
that may tip sky conditions into the partly cloudy range by sat
night, with associated slightly milder low temperatures in the upper
40s to middle 50s. High temperatures again in the middle 70s to
around 80 degrees, or so.

Long term Sunday through Thursday
As of 340 am Friday...

the ridge over the southeast will move east Sunday as a trough over
the midwest and mississippi valley deepens. We'll have another nice
day Sunday to round out the weekend's weather, featuring partly
cloudy skies (mainly high clouds) and return flow resulting in warm
temps with highs in the upper 70s to around 80.

Monday will feature increasing and lowering clouds as a closed
trough ahead of the upstream longwave trough moves across the tn
valley and moist S SW flow aloft increases over our area ahead of
this trough.

Gfs and ECMWF solutions diverge Monday night and Tuesday. The ecmwf
shows the lead short wave getting absorbed into the larger longwave
trough and ejected to the northeast 12+ hours faster than the gfs.

The ECMWF solution would result in a band of showers quickly moving
across our CWA early Tuesday morning before exiting to our east by
noon Tuesday. The slower GFS brings multiple bands of showers
across our area Monday night through about mid-day Tuesday, with
perhaps a brief opportunity for a few gusty tstms during the late
morning Tuesday before the showers exit to our east. This thanks to
the proximity of the passing mid-level trough and subsequent
stronger wind fields and resultant shear; however GFS forecast
sounding show limited instability, thus perhaps a high-shear low-
cape setup with isolated strong wind gusts the main concern if any
severe weather threat materializes. Finally, there will be another
brief opportunity for a few showers late-day Tuesday with the
passage of the sfc cold front. Coverage and intensity should be
limited though, thanks to the earlier passage of the lead short wave
and subsidence and mid-level drying in its wake.

Tuesday night we'll drying and strong CAA commence in the wake of
the cold front, with additional CAA behind the passage of the
longwave trough axis which is progged to move across our CWA late
Wednesday. The main weather story for Wednesday and Thursday will
be the chilly temps, with highs only in the low 60s both days, and
potential for lows dipping down into the upper 30s in some spots
Thursday morning.

Aviation 14z Friday through Tuesday
As of 1015 am Friday...

high pressure in proximity of the carolinas will maintainVFR
parameters through tonight. Surface winds will be light and variable
to N nely surface winds.

Outlook: continued persistence radiation fog will be possible mainly
at rwi each morning through the weekend, followed by a higher
probability of more-widespread sub-vfr conditions in stratus and
fog, in increasingly moist east to southeasterly low level flow, sun
night-mon morning. An approaching frontal system will result in a
good chance of sub-vfr conditions, showers and storms, and
strong shifting winds with height late mon-tue.

Rah watches warnings advisories
None.

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.
