Synopsis
Cold high pressure remains over the area today. A cold front will
produce light snow on Wednesday and will push offshore Wednesday
night, followed by high pressure building in from the west late in
the week.

Near term until 6 pm this evening
As of 325 am tues... Fog and low stratus continue to invade
portions of eastern nc reducing visibilities to a mile or less
at times this morning. Latest nighttime microphysics satellite
imagery, via GOES east, shows the cloud deck and associated fog
entering martin and washington counties currently, and already
covering most of tyrrell, dare, and hyde counties. The current
rate of advection is more or less following high-res guidance,
which shows fog advection all the way down to the southern coast
of carteret county later this morning. So far visibilities have
stayed above dense fog criteria, but will likely issue another
sps for fog in the coming hour.

Fog and stratus will begin to dissipate by
mid morning, and temperatures are expected to rise into the
upper 40s to low 50s this afternoon. Some shower activity is
expected across the outer banks and hyde and dare counties in
association with an inverted trough off the coast. However,
high-res guidance wasn't as robust as the previous forecast, and
have scaled back pops in this region to now be mainly over the
outer banks.

Short term 6 pm this evening through 6 am Wednesday
As of 335 am tues... Increasing clouds Tuesday night will
prohibit another night of lows in the 20s. Low temps are
expected to reach the low 30s inland, and mid 30s along the
coast. Most areas should remain dry ahead of advancing cold
through Wednesday morning.

Long term Wednesday through Monday
As of 345 am Tuesday... 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 by evening.

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. The 00z models have come
in slightly cooler suggesting a faster change over to snow
Wednesday afternoon, especially inland as a surface cold front
moves rapidly east across the area Wednesday morning. This will
be an anafront, where precip occurs behind the sfc boundary.

Thus, not expecting freezing rain, as cooling will occur from
top down. Bndry layer wet bulb temps will be near 0 degrees c
through the day, and even though sfc temps will climb to the
upper 30s north to mid 40s south, the arrival of precip will wet
bulb down to the sfc due to dynamic cooling. So expect a brief
period of rain before transitioning to a ra sn mix then quickly
to snow, from northwest areas to southeast. Right now think
timing will be early afternoon for snow across NW zones, finally
switching to snow southeast zones by early evening as the
precip is coming to an end. Best chance of light accums will be
northern and northwestern counties where deeper cold bndry layer
temps will reside. Timing of the snow should adversely affect
the afternoon and evening commute when the heaviest of the snow
is forecast to occur. Column drying occurs Wed evening as deep
layer saturation quickly erodes, and there may be a brief period
of freezing drizzle before precip comes to an end 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.

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 09z Tuesday through Saturday
Short term through Tuesday night ...

as of 340 am tues...VFR conditions expected for most of the
rest of the night before MVFR fog and ceilings creep in from the
east over the TAF sites. Lifr conditions have begun across ne
nc including the nobx, and will continue the rest of the night.

This area of fog and stratus will move westward and reach kewn
and kpgv a few hours before sunrise. Further west,VFR
conditions will remain. MVFR conditions will likely persist from
kpgv and kewn eastward through mid morning whenVFR conditions
should return.

Long term Wednesday through Saturday ...

as of 345 am Tuesday... Rain snow will impact flying conditions
Wednesday and Wednesday night, then a return toVFR conditions
are expected Thursday through Saturday with dry high pressure
forecast to be over the area.

Marine
Short term through tonight ...

as of 340 am tues... Have issued a dense fog advisory for the
coastal waters from duck to hatteras inlet, as well as the
pamlico sound, albemarle sound, and alligator river until 8 am.

Visibilities are currently 1 nm or less in many locations, and
the fog is continuing to spread south and west, and may enter
portions of the inland rivers, and southern coastal waters later
this morning.

Winds are currently N 10 to 15 kts, with seas 5-8 ft still. Sca
advisories continue for all the coastal waters, with areas
south of ocracoke inlet forecast to come down later this
afternoon. Winds will remain mostly 10-15 kts out of the nnw for
the rest of the period. Seas will be slowly coming down today
with 4-7 ft expected by mid morning, and 3-6 ft likely by
tonight.

Long term Wednesday through Saturday ...

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.

Mhx watches warnings advisories

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.
