Synopsis
An area of low pressure will approach from the south tonight
then lift northeast just inland from the coast Thursday. The
low will quickly lift to the north Thursday night pushing a cold
front offshore. High pressure will ridge into the region
Friday through the weekend. A low pressure area may skirt the
coast early next week.

Near term through tonight
As of 215 pm Wednesday... Dry air in lower lvls will keep any
precip extremely light into the evening and will just have
sprinkles mentioned. Late tonight as cstl warm front begins to
approach cst expect shra to increase in cvrg and intensity
espcly SRN cst. Signif lowered pops thru evening then cont with
categorical pops far S to chc far N late tonight. Lows will
range from lower 40s inland to upper 40s cst with temp rising
late espcly coast as onshore flow dvlps.

Short term Thursday
As of 215 pm Wednesday... Low pressure over sc Thursday morning
and will be strengthening as it lifts NE across eastern nc.

Most of the area will get into the warm sector, with the
exception of deep inland areas. Temperatures and dewpoints will
rise into the 60s and low 70s in the warm sector which will set
the stage for the possibility of severe weather. Strong low and
mid level shear will be present Thursday, however degree of
instab is in doubt as gfs ECMWF keep instab limited and along
imd cst while NAM shows signif more instab spreading inland a
bit. There is certainly a poss for some organized convection
including supercells and assoc tornado threat along the cst
with less chc as head inland. Heavy rain will also fall across
the area as pwat values approach 2", with storm total rainfall
of 1-2 inches expected over the coastal plain, and 2-3 inches
east of us 17. With many areas in eastern nc 200-300% above
normal rainfall over the past two weeks, will cont the flash
flood watch... Did shorten duration of watch as heavy precip will
be ending from W to E in aftn. High temps will range from lower
70s most of the coast to upper 50s around 60 deep inland.

Long term Thursday night through Wednesday
As of 230 pm wed... Drier high pressure will build in late week
through this weekend, and then a week coastal trough develops by
Monday and could bring some rain showers to the coast. High
pressure will then build in again through midweek. Temps will
generally be near climo.

Thursday night through Sunday... High pressure will build in
behind the departing system, and it will be cooler as much of
the us will be under a longwave trough. A modest warming trend
will be present this weekend, with highs Friday in the mid to
upper 50s, and then by Sunday high temps will reach the low to
perhaps some mid 60s across eastern nc. Low temps will dip to
the mid 30s interior, and low to mid 40s near the beaches
(except obx which will remain in upper 40s).

Monday and Tuesday... A weak coastal trough will develop by
Monday, which could bring some rain showers east of us 17, esp
late Sunday night through the first half of the day Monday.

Will raise pops just a bit near the coast (30-50%) based on the
14 12z ecm cmc, but keep coastal plains in only slght chc. High
pressure will build in again from the north on Tuesday, with
dry weather expected. High temps will range from 60-65 Monday,
with slightly cooler conditions expected Tuesday. Lows continue
to be around average in the upper 30s to mid 40s.

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.
