1110 am edt Sat apr 29 2017

High pressure will extend across the area from offshore through
Sunday. Near record high temperatures today in a few places and
still warm and humid on Sunday. A cold front will bring a
likelihood of showers and thunderstorms late Monday into early
Tuesday. High pressure will follow for the mid-week period. A
low pressure system will impact the region Thursday into Friday
amd may bring widespread showers and thunderstorms and heavy

Near term /through tonight/
As of 1100 am Saturday... Near record high temps today, lower 90s
inland and upper 80s to near 90 closer to the coast. Only the
beaches will hold in the lower to mid 80s.

Location predicted high record high
wilmington 87 92 set in 1975
north myrtle beach 81 90 set in 2002
florence 91 91 set in 1981
lumberton 91 no established record
a very humid air mass will continue to maintain dewpoints near
70 to the lower and mid 70s this afternoon. A strong seabreeze
will push slowly inland and this will kick winds up to 15 to 20
mph with higher gusts along and on the marine side of the

A shallow layer of moisture will allow cumulus clouds to
develop, but with dry air aloft, the clouds should lack vertical
depth and are not expected to grow sufficiently to support any
showers, even along the sharp seabreeze this afternoon and eve.

Tonight, winds above the boundary layer should be sufficiently
strong to preclude widespread fog development. However, soundings
and moisture profiles show low stratus redeveloping on a fairly
widespread basis. It will be a warm and muggy night with lows
near 70 to the lower and mid 70s, warmest at the beaches.

Short term /Sunday through Monday night/
As of 300 am Saturday... Chances for convection increase through
the period as a cold front moves east across the coastal
carolinas, with a deep upper trough descending upon central
conus. High pressure over the western atlantic will retreat east
as the cold front approaches, with Sunday being generally dry
other than some spotty afternoon sea-breeze related convection.

Pops increase on Monday, maxing out in the likely category
Monday night as the front moves across the forecast area. Steady
sw flow in advance of the front will maintain above-normal
temperatures for both days, with highs in the mid 80s (lower at
the coast) and lows in the 60s.

Long term /Tuesday through Friday/
As of 300 pm Friday... A cold front will move off the coast tue
morning and high pressure along the gulf coast will slide east
and then offshore to our S during wed. This should bring a dry
period. Deep low pressure will move out of the mid south and
gulf coast states wed, lifting slowly to the ne. Its associated
cold front will move into the southeast states thu-thu night,
bringing the risk for robust thunderstorms.

Aviation /12z Saturday through Wednesday/
As of 12z Saturday... Main forecast uncertainty regards when
patchy stratus currently blanketing area will break up. Although
overall confidence low that stratus will lift by mid- morning,
satellite loops show myr and cre will likely be most affected
due to a large and persistent area of offshore stratus. A return
to ifr/MVFR conditions possible again overnight.

Extended outlook... Periods of ifr/MVFR conditions are possible
in showers and thunderstorms late Monday into early Tuesday.

Near term /through tonight/...

as of 1100 am Saturday... Southerly return flow around offshore
high pressure will keep winds from the S through tonight. Wind
speeds will be sustained at 10 to 15 kt, however, across the
near shore waters, a stout seabreeze circulation will bring
wind gusts up to 20 kt or so this afternoon and early eve.

Seas will be around 3 ft throughout.

Short term /Sunday through Monday night/...

as of 300 am Saturday... Increasing SW flow in advance of the
next cold front will make it likely that a small craft advisory
will need to be issued on Monday for winds gusting up to around
30 kt. By Monday night seas will have built to 4 to 7 ft
although winds may slacken in the pre-dawn hours of Tuesday as
the front makes its close approach. Sunday looks to be the
better day for boating, with seas of right around 3 ft and winds
of 10 to 15 kt.

Long term /Tuesday through Wednesday/...

as of 300 pm Friday... In the wake of the cold frontal passage
early Tuesday, offshore winds will slowly diminish. The offshore
trajectories will knock seas down and should drop below small
craft advisory levels by Tuesday afternoon. There are no
concerns for Wednesday into Thursday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
