An approaching cold front will bring a chance of rain overnight.

Breezy and cooler weather is expected Tuesday and Wednesday as
high pressure builds from the north. The high will move off the
coast late Thursday, with a warming trend into next weekend. A
cold front may bring a few showers next Sunday.

Near term through Tuesday night
As of 4 pm Monday... CU developed inland and remain clustered
along the sea breeze boundary just inland leaving the coast with
mostly sunny skies. Gusty SW winds, along with westerly
downslope flow in the low levels have helped to push temps up
into the mid 70s this afternoon. Could see an iso shwr this
aftn, but the best chc of convection will come later today into
this evening ahead of cold front approaching from the west. Pcp
water level reaches up close to 1.25 inches this evening, but
instability seems weak and remains elevated as the moisture
increases through the column this eve. Soundings also show a
defined dry layer in the first few thousand feet. Overall expect
showers increasing across the i-95 corridor between 8p and 10p
this evening. SPC has area in general thunder with only isolated
tstm coverage expected. A broken line of shwrs iso storms will
progress slowly eastward overnight as the storm movement remains
out of the sw. The front should drop south of the area by
daybreak with the last shwrs should exiting the nc coast as a
shortwave makes its way off the coast. Cooler air will feed in
from the NW with temps making it down just below 50 over the
lumberton area and mid 50s closer to the sc coast.

Temps will not rise much from overnight lows on tues. Temps
will not even make it to 60 most places and brisk northerly
winds will make it feel even cooler. Skies will clear with
increasing sunshine later in the day as dry and cool air feeds
into the area on the back end of exiting low pressure.

Skies will clear by tues night as high pressure builds in, but
gradient remains tight with enhanced n-ne flow. The northerly
flow will continue to drive CAA through the night with temps
dropping down into the 30s. A few spots could reach down toward

Short term Wednesday through Thursday night
As of 4 pm Monday... "cool and dry" may summarize this period,
as cold air advection encompasses most of this time. Winter to
dip its foot into the carolinas, with Wednesday morning wind
chills in the upper 20s, in brisk nne breezes at daybreak. The
ne low level marine flow should help spur a few afternoon fair
weather cumulus otherwise mainly clear this period. Highs and
lows both to run a bit below average compared to climate. As a
result, the primary hazard is frost or isolated freezes in the
early mornings.

Long term Friday through Monday
As of 4 pm Monday... A pleasant 'return to spring' feel shaping
up for the extended period, as a high slips off the coast,
allowing return flow and building warm air advection to set the
stage for a weekend warm up, 5-8 degrees above average.

Gfs ECMWF both resolving cold front transit here Sunday,
handling differences in moisture, but small chance of rain looks

Aviation 00z Tuesday through Saturday
As of 0z... .A cold front, and accompanying rain showers, is
currently making its way across the western boundary of our cwa.

Elevated rain chances through tomorrow morning as a shortwave
will continue to provide lift behind front. Slight chance of a stray
thunderstorm over next few hours. Cloud deck between 5 and 10 kft
will become MVFR at inland terminals around 6z and coastal terminals
around 9z. Chance ceilings could become ifr briefly, but confidence
too low for TAF inclusion. Ceilings should improve toVFR around 18z
tomorrow, with skies clearing shortly after. Southwest winds to become
quickly northerly behind frontal passage, with gusty north winds
tomorrow sustained around 15kts and gusting into the 20s.

Extended outlook... MVFR ifr conditions Tuesday, becomingVFR during
the day.VFR remains in place through the rest of the week.

As of 4 pm Monday... Gusty s-sw winds will continue ahead of an
approaching cold front into tonight. Low pressure will lift off
to the northeast dragging the cold front through the waters by
early tues morning. As the winds reach up to 10 to 20 kts out of
the SW this evening, seas will bump up to 3 to 5 ft, but the
main increase in winds and seas will come on the back end of the
low through late tues into wed. Seas should rise above sca
thresholds tues aftn, reaching up to 5 to 8 ft through tues
night as brisk northerly winds reach up to 20 to 30 kts with
gusts up above gale force. Will upgrade gale watch to gale
warning with this forecast package beginning late tues.

Wednesday the ocean is still dangerous, but a slow recovery
will begin later in the day as winds trend down. Thus it is
likely that a period of 'small craft advisory' will follow,
after the gale flags are lowered. Easing winds into late week
will set up very fine marine conditions into the weekend, with a
wave mix of weak SE swell and NE waves 1-2 feet, both wave
trains around 8 seconds. A front is expected to cross the coast
late Saturday or Sunday.

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 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.
