High pressure will gradually move offshore today. A strong cold
front will move through the area early Sunday. High pressure
will be over the area Monday into Tuesday. A cold front will
cross the area Tuesday night followed by high pressure for mid
to late next week.

Near term through today
As of 300 am Saturday... High pressure moving offshore and strong
cold front will produce pre-frontal warm sector conditions over
area today. Initial weak short wave will result in increasing
high clouds this morning with some CU scu development this
afternoon. Low level thicknesses increasing to 1360-1365 meters
support MAX temps 65-70.

Short term tonight
As of 300 am Saturday... Models remain consistent with positively
tilted short wave and associated cold front moving into area
late tonight and near coast by 7 am Sunday. With main dynamics
moving north of area, models continue to indicate main
widespread precip over NW third of area and increased pops to
likely there with solid chance pops rest of area. Bulk shear of
50-60 kt indicated but negligible CAPE instability, this
expecting only showers but any heavier activity could produce
gusty winds. Stronger gradient winds of 25-35 mph support wind
advisory for outer banks and eastern carteret county. Min temps
from mid 50s inland to near 60 coast.

Long term Sunday through Friday
As of 230 am sat... A cold front will move off the coast Sunday
morning. High pressure then builds in Monday and Tuesday.

Another front will move off the coast Wednesday morning. Low
pressure will pass by to the southeast thanksgiving day into

Sunday... The cold front is expected to cross eastern nc Sunday
morning, with showers quickly ending from west to east before
noon. Precipitation amounts will be light, mainly 0.10" or less
in most areas. Low temps Sunday morning will be mild, in the
50s, as we will still be receiving strong warm air advection.

Highs on Sunday will be cooler, with temps only rising 5-6
degrees from the morning lows behind the cold front.

Monday and Tuesday... High pressure will build in from the west
Monday and then move off the coast on Tuesday. Cold air aloft
will lead to much below normal highs on Monday, but then warmer
southerly flow on Tuesday will lead to milder highs. Highs
Monday will be in the mid 50s, and on Tuesday highs will reach
60-65. Low temps will be in the lower to mid 30s inland both
Monday and Tuesday mornings, with mid to upper 30s further east,
and low to mid 40s along the coast.

Wednesday thru Friday... Another fast-moving front will move off
the coast Wednesday morning. After that, an offshore trough
will develop and move over the gulf stream on Wednesday, and
will bring showers to eastern nc. Have slight chance pops west
of highway 17 and chance east. Low pressure will pass by to the
southeast Thursday and Friday. GFS is much stronger with the
low, while the ECMWF is much weaker. Consensus is favoring the
ecmwf solution at this time. Will carry mostly slight chance
pops Thursday and Friday.

High temps will be in the mid 60s Wednesday, and then the mid
50s Thursday and 55-60 Friday. Low temps Wed will range from
the mid 40s inland to the upper 40s to low 50s along the coast.

Lows Thursday will be around 40 on the coastal plain to 45-50
south coast and obx. Lows Friday morning will be in the mid to
upper 30s coastal plain to mid upper 40s south coast and obx.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
