Synopsis
A cold front will approach the area tonight, and produce light
snow across eastern north carolina Wednesday into Wednesday
night. High pressure will build in from the west Thursday
through the weekend.

Near term until 6 am this morning
As of 1 am wed... Fog and low stratus are still plaguing the
nobx tonight with visibilities reduced to 1-4 miles. Foggy
conditions will likely continue through the early morning until
after sunrise. Also, with some locations below freezing,
freezing fog will be possible, and could lead to some icy spots
on roads and bridges.

Low temps are currently in the upper 20s to low 30s across
eastern nc. Temperatures will mostly hover around these marks
the rest of the night as mid high clouds continue to move
through the region.

Short term 6 am this morning through 6 pm Thursday
As of 4 pm tues... Wednesday through Wednesday evening will be
the focus for wintry weather as rain quickly mixes with then
changes over to snow across most of eastern nc starting late in
the morning for the coastal plain and ending in the evening for
the coast.

Fortunately the system will have limited moisture with most
model QPF forecasts indicating 0.25" or less of water
equivalent. Nonetheless, the system will have good forcing to
wring out what moisture is available, as model x-sections
indicate decent fgen banding in the 900-700mb layer, which
co-located with the dgz may produce some decent snow rates at
times, leading to a quick one to two inches of accums for
northwest half of the fa. Initial energy will go into cooling
the boundary layer, as sfc temps will rise into the 40s before
the snow begins, therefore a brief period of rain may fall
before dynamic cooling quickly cools the low levels sufficiently
and switches to snow. This will be an anafront, where precip
occurs behind the sfc boundary. Thus, not expecting an initial
period of freezing rain, as cooling will occur from top down.

In addition, no warm nose will be present as there is little to
no sfc reflection offshore. Timing of the snow will adversely
affect the afternoon and evening commute when the heaviest of
the snow is forecast to occur. Column drying occurs from the top
down Wed evening as deep layer saturation quickly erodes, and
there may even be a brief period of freezing drizzle before
precip comes to an end on the coast around midnight. Roads will
likely be treacherous where snow falls through thur morning as
overnight lows Wed night expected in the upper teens to lower
20s inland to 25-30 immediate coast.

Long term Thursday night through Tuesday
As of 345 am Tuesday...

Thursday through Sunday... Cold and dry conditions will follow
this low pressure system, with high temps Thursday only topping
out in the upper 30s across the area. Low temps will be very
cold Thursday and Friday mornings with teens expected inland,
and 20s along the coast. As the cold upper trough moves away on
Friday, high temperatures will moderate to around 50. High
pressure moving off the coast, and rising heights will allow
temperatures to warm above average over the weekend, with dry
weather expected.

Monday... A cold front will approach late Monday bringing a
threat of showers to area by evening. Mild temperatures will
continue ahead of the front with highs in the lower to middle
60s expected.

Aviation 06z Wednesday through Sunday
Short term through Wednesday night ...

as of 1 am wed...VFR conditions are expected through the first
half of the TAF period, with conditions dropping to MVFR levels
and eventually ifr levels Wednesday afternoon. Mid and high
level clouds will continue to move through the region tonight
and Wednesday morning. Then, as a cold front crosses the region,
rain will begin Wednesday afternoon, and quickly transition to
snow, which will bring flying conditions down to MVFR and then
ifr by the evening. Ifr conditions will persist through the
first part of Wednesday night, with improving conditions after
midnight.

Long term Wednesday night through Sunday ...

as of 3 pm tue... Light snow will likely impact conditions
Wednesday evening with widespread sub-vfr conditions likely,
then improving toVFR by early Thursday morning.VFR conditions
expected Thursday through Sunday with dry high pressure forecast
to be over the area.

Marine
Short term through Wednesday night ...

as of 830 pm tue... High pressure weakens over the waters tonight
with light and variable winds, generally less than 10 kt, and
seas around 3-6 ft. Seas north of ocracoke expected to remain
mostly at or above 6 ft overnight into wed. A cold front will
move through the waters Wed afternoon, with northerly winds
increasing quickly along with building seas. Northerly winds
peak at 20-30 kt with seas 5-9 ft Wed night. A brief period of
gale force gusts will be possible across the central waters wed
night. SCA advisories continue for the waters north of ocracoke,
and issued for the southern waters and sounds beginning wed
afternoon.

Areas of fog and stratus continue to impact the northern obx
and adjacent coastal waters this evening with manteo and first
flight airports reporting 1 4 to 1 2 mile visibilities. Guidance
continues to spread the fog south and west through the overnight
but rapid refresh runs have been gradually backing off on the
extent so confidence on just how far it will spread remains
low. In addition, high clouds are hampering the ability to see
the fog via satellite making it difficult to ascertain the true
extent of the fog. Have issued a dense fog advisory for the
albemarle sound and coastal waters north of oregon inlet at this
time and may need to expand the advisory if conditions warrant.

Long term Thursday through Sunday ...

as of 345 am Tuesday... Small craft conditions will persist
across the through Thursday dues to gusty northerly winds 20 to
25 kt through Thursday morning and hazardous 5 to 8 ft seas
through Thursday afternoon. Winds and seas slowly decrease late
Thursday afternoon. Friday and Saturday W SW flow around 15 kt
is expected with seas 3-5 ft Friday and 2 to 4 ft Saturday.

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.
