Synopsis
High pressure will build in from the northwest today and
continue north of the area through the weekend. Slow moving low
pressure will impact the area early to mid next week.

Near term until 6 pm this evening
As of 940 am fri... Latest sfc analysis shows 1033 mb parent
high pressure centered over the upper mid-west extending
southeast into eastern nc where a secondary center was beginning
to take form. This has resulted in very dry airmass across the
region with very little moisture in atmosphere as evidenced in
the 12z mhx sounding. Pw values were down to 0.15" more
reminiscent of a winter cp airmass. Skies will remain clear
today but with persistent northerly flow, highs will be well
below normal values ranging from the low 50s outer banks, to 55
to 60 east zones and low to mid 60s western counties. This is
about 15-20 degrees colder than yesterday and about 10 degrees
below normal. As the secondary high center develops over the
area this morning winds will be diminishing.

Short term 6 pm this evening through 6 am Saturday
As of 2 am fri... High pressure will continue to build into the
area from the north tonight. Mostly clear skies and light winds
will lead to excellent radiational cooling conditions across the
area resulting in another chilly night. Main challenge for the
overnight is the frost potential inland. If winds are able to
decouple and dewpoints rebound, could see areas of patchy frost
develop inland. Lows in the upper 30s to low 40s.

Long term Saturday through Thursday
As of 300 am fri...

Saturday and Sunday... Sfc high pressure will dominate the region
through Sunday. Meanwhile to the west, an upper level low will move
across the southern plains lower ms valley, while at the sfc an area
of low pressure develops over the gulf states. Expect mostly sunny
with mild temps Saturday, then Sunday an increase of clouds ahead of
the low pressure system. Expect Saturday's highs in the mid 50s in
the NE sections of the forecast area to mid 60s to the sw, then
Sunday expect temps to increase to the upper 50s to the NE to upper
60s SW of the area. Overnight lows... Saturday night, the low mid 40s
inland and mid upper 40s coast, then Sunday night, in the mid upper
40s inland to low mid 50s coast.

Monday through Thursday... The 00z models continue to show a good
agreement with the sfc low over the gulf states and lifting towards
the carolinas tues wed, but models don't have a good handle when the
upper level low will weaken and lift north. Then a significant
shortwave will drop from the northern plains towards the southeast
Wednesday with a weak cold front associated with it and expected to
push through thurs or Friday. Overall, expect cloudy conditions with
isolated to scattered showers on Monday, then becoming widespread
Monday night and Tuesday as the sfc low is to the south of the area.

Tuesday night Wednesday the low will lift across nc with rain
chances lowering. There will be a brief break from rain Wed until
rain developed again with the shortwaves and approaching cold front.

The warming trends will continue through Thursday with highs in the
upper 60s low 70s inland and low mid 60s outer banks.

Aviation 18z Friday through Wednesday
Short term through Saturday ...

as of 145 pm Friday... High pressure surface and aloft will
build into the region through the period bringing mainly clear
skies with a high confidence ofVFR conditions. North to
northwest winds may gust to around 15 kt for the next couple
hours but generally winds diminish through the afternoon. Light
and variable winds are expected tonight and Saturday.

Long term Saturday night through Wednesday ...

as of 300 am fri...VFR conditions will dominate most the taf
period. High pressure will continue to dominate through Sunday.

Mid to high clouds will increase across the region Sunday, ahead
of a low pressure system. This low will bring scattered to
widespread Monday and Tuesday... Leading to MVFR with possible
ifr conditions Tuesday. Improving conditions expected Wednesday
with the low lifting north of the area.

Marine
Short term through tonight ...

as of 940 am fri... Gusty winds and elevated seas continue
across the waters this morning and will gradually subside this
afternoon as high pressure builds over the area. With winds
still gusting to 25 kt over the southern and central waters will
need to extend the SCA into early afternoon. 5-7 ft seas this
morning will be subsiding to 2-5 ft this afternoon. N NE winds
5-15 kt are forecast overnight with seas 2-4 ft.

Long term Saturday through Tuesday ...

as of 315 am fri... Northerly 5-15 knots will continue Saturday, then
winds will slowly veer to the NE Saturday night through Sunday as
the high pressure gradually shifts off the mid-atlantic coast. Wind
gradient will tighten Monday as a low pressure system approaches the
region from the gulf states, expect winds to become ene 10-20 knots,
then increasing to 20-30 knots Tuesday. Seas will generally be
around 2-3 ft through early Monday morning, then seas will build 4-6
ft throughout Monday. Seas will continue to build Monday night and
Tuesday as the sfc low approaches the area, expect seas to reach as
high 10-13 ft.

Mhx watches warnings advisories
Nc... None.

Marine... Small craft advisory until 2 pm edt this afternoon for amz150-
152-154-156-158.

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.
