Synopsis
High pressure will build south of the region today. Two dry
cold fronts will cross the area this week, the first one
Tuesday, the second one Thursday night.

Near term through today
As of 230 am Monday... High pressure will continue to build over
the area from the south today producing clear skies and light
winds. Highs will be in the lower to mid 50s.

Short term tonight
As of 230 am Monday... A dry cold front will approach from the
west late. Initially light winds clear skies early will lead to
strong radiational cooling and rapidly falling evening
temperatures. Then late tonight as the front approaches winds
could increase late as the pressure gradient tightens. Thus low
temps could occur around midnight with steady or slowly rising
temps late.

Long term Tuesday through Sunday
As of 300 am mon... Another shot of arctic air will surge in tue
night and Wed as upper trof crosses the region. Models are dry
with limited moisture so no precip expected. Very cold Wed with
lows in the mid 20s inland to low 30s coast and highs mainly
upper 30s to lower 40s.

Another front moves through late in the week. Timing of this
feature much in question. HPC surface prog has it passing
through Thursday. However, the latest run of both the GFS and
the ECMWF are much slower with it, bringing it through fri
afternoon. Because of this, I will continue the dry forecast for
late week as moisture still appears limited. The weekend looks
dry with high pressure building into the region from the
southwest.

Highs Thu upper 40s to lower 50s and mostly lower mid 50s fri
and upper 40s to lower 50s sat. Temps moderate a bit Sunday with
highs in the mid upper 50s.

Aviation 07z Monday through Friday
Short term through tonight ...

as of 230 am Monday... High confidence in mainlyVFR conditions
through tonight as high pressure prevails today and a dry cold
front approaches late tonight. Expecting mostly clear skies and
light winds through the period. Early this morning, if winds
decouple, then patchy shallow ground fog could occur with a
brief period of subVFR visibilities possible.

Long term Tuesday through Friday ...

as of 300 am mon...VFR dry weather expected with partly cloudy to
mostly clear skies.

Marine
Short term through tonight ...

as of 230 am Monday... Small craft advisory conditions are
expected to develop late tonight as a strong cold front
approaches from the west thus advisories have been issued for
all of the near shore waters and the pamlico sound. Through this
morning westerly winds 15 to 20 kt will diminish to 5 to 10 kt
this afternoon and evening as high pressure to south builds over
the waters. Then late tonight (after midnight) the pressure
gradient will tighten as the cold front approaches causing winds
to increase to SW 15 to 25 kt. Seas 3 to 5 ft this morning will
subside to 2 to 3 ft late this afternoon and evening then build
to 4 to 7 ft toward Tuesday morning.

Long term Tuesday through Friday ...

as of 300 am mon... The long term will feature mostly poor
boating conditions for the coastal waters and sounds. Two dry
fronts will pass through the area, one on Tuesday and the other
on Thursday.

The flow will be westerly through the period, with the strongest
winds Tuesday into Wednesday at 20-30 knots on the coastal
waters and pamlico sound. Small craft advisories are now in
effect for those zones. A few gusts to gale force will be
possible Tuesday and Tuesday night on the coastal waters.

Winds Thursday and Friday will average 10-20 knots, with 20-25
knots possible from hatteras to ocracoke on Friday.

Seas on the coastal waters will be highest Tuesday and Tuesday
night, averaging 5-9 feet. Seas will remain elevated for the
remainder of the period, with small craft conditions continuing
through the end of the week for most of the coastal waters.

Mhx watches warnings advisories
Nc... None.

Marine... Small craft advisory from 4 am Tuesday to 7 pm est Wednesday
for amz135-150.

Small craft advisory from 4 am Tuesday to 7 pm est Friday for

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.
