320 pm edt Sat mar 23 2019

Synopsis
High pressure will pass through the area tonight and Sunday. A
storm system will impact the region Monday into Tuesday. High
pressure building down the east coast will then dominate later
Tuesday into the second half of the week.

Near term until 6 am Sunday morning
As of 320 pm sat... High pressure centered just to the northwest
this afternoon will be centered directly on top of the forecast
area by early Sunday morning. Breezy west to northwest winds
this afternoon will quickly drop to calm throughout early this
evening. Excellent radiational cooling will take place overnight
with clear skies, calm winds in an extremely dry atmosphere.

Have upgraded the freeze watch to a freeze warning, and added in
mainland dare county. Low temps around 30 along the coastal
plain to lower 30s close to the coast.

Short term 6 am Sunday morning through 6 pm Sunday
As of 320 pm sat... The center of the high will shift off the
coast during the day with a light south to southwest flow
developing in the late morning into the afternoon. Still a very
dry atmosphere in place which will allow temps to climb quickly
in the morning into the afternoon. High temps will reach the
upper 50s lower 60s northeast and outer banks, upper 60s to near
70 elsewhere.

Long term Sunday night through Saturday
As of 320 pm sat... Unsettled to start the period as a complex
low pressure area and front affect the region, then dry high
pressure builds in with mainly dry and seasonably mild temps
second half of the period.

Sunday night through Tuesday... Sunday night will continue dry as
area is under influence of higher hts, though a complex and
atypical upper level patten will emerge early next week as the
area of greatest energy associated with a shortwave aloft slides
from the northern jet stream across the missouri valley early
Monday to the southern stream across the carolinas by Tuesday
morning. The result is a complex and broad frontal system that
will impact the east coast Monday into early Tuesday. Locally,
moisture advection will be strongest Monday as we will be
located within the warm sector of the approaching system.

Surface low pressure will slide across the appalachians into the
carolinas later Monday. Guidance is resolving a complex low by
the time it reaches our area Monday night, with the primary low
center passing to our south, but a secondary low possibly
forming near over eastern nc. While exact details and
characteristics of the rainfall remain uncertain, the wettest
period should be late Monday afternoon through overnight Monday,
when column destabilization is greatest ahead of and near the
passing low. A few rumbles of thunder are also possible, though
instability appears too low for a severe threat.

Gusty winds and some coastal flood concerns will emerge late mon
night and ESP tue, as low offshore in tandem with building high
across the great lakes mid atlantic strengthen gradient winds.

Wind adv criteria (gusts > 45mph) may be met for coastal
counties for a time, and may lead to minor coastal flooding as
persistent nne winds occur through at least Tue night.

Wednesday through Saturday... High pressure ridging down the
east coast will dominate locally, keeping a mainly dry forecast
in place for the second half of the workweek as low pressure
stalls well offshore. Northeast winds will prevail, though they
will gradually diminish through the period. Accordingly, temps
will trend from below normal Wednesday to above normal by
Friday. High pres should finally ridge overhead by next weekend,
bringing very pleasant spring-like conditions to the region.

Aviation 19z Saturday through Thursday
Short term through 18z sun
as of 320 pm sat...VFR skc through the short term. Northwest
winds will quickly diminish to calm early this evening and
continue through mid-morning Sunday. Light south to southwest
winds will develop by midday Sunday.

Long term Sunday night through Thursday ...

as of 320 pm sat...VFR conditions will prevail through sun
night. Flight restrictions are then possible Monday through
Tuesday morning as a broad and complex storm system impacts the
area.VFR conditions and gusty northeasterly winds arrive during
the day Tuesday, likely continuing through Wednesday.

Marine
Short term through sun
as of 320 pm sat... Seas have subsided below 6 feet in the
oregon inlet to ocracoke zones have cancelled the small craft
advisory that was set to expire at 5 pm. High pressure will pass
through the marine zones tonight and Sunday. Winds this evening
of 5-15 knots will diminish to 5-10 knots after midnight,
continuing Sunday. Seas tonight will be 2-4 feet north of oregon
inlet and south of ocracoke, 3-5 feet in between. Seas Sunday
will be 2-3 feet throughout.

Long term Sunday night through Thursday ...

as of 320 pm sat... Southerly flow will increase Sun night ahead
of a complex low pressure frontal system approaching from the
west. The cold front low pressure area will pass off the coast
Tuesday morning. The low will deepen offshore Tuesday as high
pressure builds inland, resulting in strong north to northeast
winds developing. Gale conditions are likely on Tuesday into
Tuesday night as low pressure remains stalled well offshore,
keeping the gradient tight locally. Winds will slowly diminish
on Wed though likely persist in the strong SCA range.

Seas will remain fairly benign Sunday night through Monday
night, though will build slightly in response to developing
southerly southwesterly winds in the 10-20 kt range, building up
to as high as 4 ft late Mon night in choppy wind swell. Strong
northeasterly winds will bring rapidly increasing northeast
windswell as the low frontal system moves well offshore Tuesday,
and seas will become large and dangerous Tuesday through
Wednesday.

Mhx watches warnings advisories
Nc... Freeze warning from 2 am to 8 am edt Sunday for ncz029-044>047-
079>081-090>095-098.

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.
