Synopsis
A complex low pressure system will continue to impact eastern
north carolina today then move northeast away from the region
tonight. High pressure in the central atlantic will build in
Wednesday through the weekend bringing above normal temperatures
and below normal rain chances. A cold front will approach from
the west Monday.

Near term /today/
As of 715 am tue... Latest analysis shows sfc low around the
pamlico sound and outer banks, with the upper low along the
sc/nc coast. Low becomes vertically stacked today and lifts
across eastern nc. Latest radar imagery shows widespread
moderate to heavy rainfall pushing through the NW CWA this
morning, pushing westward, and should clear the CWA in the next
hour or so. Flash flood watch continues through early this
morning for those counties, and dropped for southern counties.

Updated pops based on radar trends. While deepest moisture
slides off the coast early today, scattered showers and isolated
thunderstorms through the day as the stacked low tracks
overhead. Steep mid level lapse rates and cold temps aloft could
result in some small hail. Low level thickness values and 850mb
temps support highs in the low/mid 70s.

Short term /tonight/
As of 255 am tue... Stacked low will lift off to the nne
tonight, with shower chances tapering off. Think winds will stay
up overnight to inhibit fog development, but could see
increasing low stratus develop late. Mild overnight with lows in
the upper 50s/low 60s.

Long term /Wednesday through Monday/
As of 230 am tue... Surface high pres over the atlantic combined
with ridging aloft will lead to warm and mainly dry weather
through the weekend. Increasingly moist airmass may lead to some
isold aftn and evening tsra along the sea breeze inland from
time to time but most locations will see no rain. Highs on wed
will be in the mid 70s to lower 80s then warm to 85 to 90 inland
and upper 70s to lower 80s beaches Thu through mon. Lows will
be mostly in the 60s with some lower 70s closer to the coast. A
cold front will approach from the W Mon but looks like bulk of
the day will remain rain free.

Aviation /12z Tuesday through Saturday/
Short term /through tonight/...

as of 715 am tue... Widespread sub-vfr conditions currently
across the terminals ranging from lifr toVFR, with rain
gradually tapering off this morning. Should see improving
conditions late morning becomingVFR. Scattered showers/iso
tstms late morning into the early evening. Forecast soundings
and guidance show low stratus developing late tonight and early
wed morning, with the potential for ifr ceilings.

Long term /wed through sat/...

as of 230 am tue...VFR should dominate this period with warm sw
flow around offshore high pres. Isold late day tsra poss but
just a very small chc will see any subVFR impact a terminal.

Marine

but dangerous seas will continue. Replaced gales with sca. Latest

lingering today and tonight. Seas subsiding to 5-10 feet by

period of mainly SW flow this period. Speeds will avg 10 to 15
kts but may occasionally reach 15 to 20 kts espcly during the
aftn and early evening. Lingering swells will keep seas in the 5
to 7 foot range Wed then shld be 3 to 5 ft Thu into sat.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
