Synopsis
Canadian high pressure will build into the carolinas today and move
offshore tonight.

Near term through tonight
As of 912 pm edt Tuesday...

strong subsidence in the wave of the exiting shortwave trough
pushing east of the area is leading to abrupt clearing this evening.

Thereafter, canadian high pressure will build into the region
advecting cooler and drier air into the carolinas. This drier cooler
air mass and a near calm sfc regime at the surface will allow for
very pleasant comfortable conditions with overnight lows cooling
into the 50s overnight across the piedmont, and near 60-lower 60s
across the sandhills and southern coastal plain. Enjoy, this may the
last sub 60 degree readings for quite some time!

Short term Wednesday and Wednesday night
As of 310 pm edt Tuesday...

an area of high pressure at the surface coupled with rising heights
aloft translates to dry and pleasant conditions for Wednesday and
Wednesday night. The sfc high will deposit a dry air mass over
central nc, maintaining dewpoints int the 50s. After the seasonably
cool start, afternoon temperatures will rebound into the low-mid
80s.

The center of the high will drift offshore by early Thursday
evening, initiating a return sly flow across the nc piedmont. Thus,
dewpoints will start to inch upward indicative of the return of low
level moisture. Still, under mostly clear skies, overnight
temperatures will remain comfortable for this time of year,
generally near 60-lower 60s.

Long term Thursday through Tuesday
As of 300 pm edt Tuesday...

a subtle upper level low in vicinity of the tx gulf coast this
afternoon is progged to meander slowly NE into the deep south on thu
before deamplifying lifting NE across portions of the carolinas on
fri. Expect dry conditions to persist on thu, followed by an
increasing potential for convection Fri afternoon evening as the
deamplifying upper wave lifts NE across the carolinas and southerly
return flow strengthens (temps moisture rebound toward climatology).

Cyclonic flow aloft will strengthen over the eastern us this weekend
as a potent upper level low (currently in alberta) digs SE into the
great lakes (sat) and lifts NE across new england (sun). Broad
troughing aloft will suppress confine the sub-tropical ridge to the
fl peninsula and aid in the development maintenance of a pronounced
surface trough east of the appalachians over the weekend. With the
above in mind, expect above normal chances for convection and near
normal temperatures Sat sun. Forecast confidence decreases early
next week. Several mcs's are expected to develop upstream of the
region Mon Tue as shortwave energy in NW flow aloft progresses from
the rockies into the central plains central ms river valley. In
general, temperatures are expected to increase as flow aloft over
the mid-atlantic weakens flattens and the previously suppressed sub-
tropical ridge expands northward from fl into the deep south
southeast, and the relative best potential for convection should
shift along east of the hwy 1 corridor, though coverage timing may
ultimately depend on the evolution of upstream mcs's. -vincent

Aviation 06z Wednesday through Sunday
As of 140 am edt Wednesday...

24 hour TAF period:VFR conditions will continue through the 24 hour
taf period as surface high pressure builds into and across the
region. This will result in light and variable winds and mostly
clear skies.

Outlook:VFR conditions are expected to continue through Thursday
evening. A moistening southerly return flow will allow for the
chance of early-mid morning sub-vfr conditions from Friday morning
on, with an increase in mostly diurnal showers and storms from
Friday afternoon onward.

Rah watches warnings advisories
None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
