Synopsis
High pressure will build in from the north through the weekend.

A slow moving low pressure system will impact the area Monday
through Wednesday. A cold front is expected to push through the
area region next week.

Near term through today
As of 2 am sat... Latest sfc analysis shows sprawling 1033mb
high pressure centered over michigan wisconsin early this
morning, extending through the eastern us. Could see some
patchy frost mainly inland early this morning with temps
dropping into the mid 30s. Low level thickness values and
mostly sunny skies support highs ranging from the mid 50s
across the northern outer banks to upper 60s inland.

Short term tonight
As of 2 am sat... High pressure will continue to extend over the
area from the north tonight. Another cool night expected, with
decent radiational set up, but think it will be a few degrees
warmer than previous nights as low level flow becomes more
easterly. Could see some increasing high clouds across the
northern forecast area late. Not expecting any frost concerns at
this time with lows in the upper 30s to low 40s.

Long term Sunday through Friday
As of 330 pm fri...

Sunday... Sfc high pressure will prevail across the region
through Sunday with continued dry and seasonably cool
conditions. Highs will moderate into the mid to upper 60s
Sunday.

Monday through Friday... Unsettled conditions are expected
through the period as a energetic mean upper trough develops
over the eastern us. Mon it appears that the surface high will
delay precipitation onset associated with a upper low lifting ne
out of the deep south and not expecting much rainfall before 8
pm (00z) with best chance south and west late. The upper low
will become an open wave as it becomes absorbed phases with a
northern stream shortwave Mon night and tue. This is when the
models track a developing low across the area. There is a
potential for heavy rains in excess of 1 inch Mon night into tue
as high theta-e air gets advected off the gulf-stream. Will
have to watch for isolated severe potential with inland tracking
surface low Tue and backed low level SE flow but instability
remains in question. Dry slotting will end the widespread
precipitation threat Tue evening as the sfc low lifts NE of the
area but additional mid level shortwave energy will drop from
the northern plains towards the southeast Wednesday with a weak
cold front associated with it and expected to push through thurs
with a secondary cold frontal passage possible on Friday
keeping the threat of showers in the forecast into at least thu.

The warming trend will continue through Thursday with highs in
the upper 60s low 70s inland Tue and low to mid 70s Wed and
thu. Cooler 60s are expected along the coast.

Aviation 06z Saturday through Wednesday
Short term through tonight ...

as of 2 am sat... PredVFR conditions expected through the period
with mostly clear skies. Could see some increasing high clouds
late tonight and early Sun morning.

Long term Sunday through Wednesday ...

as of 330 pm fri...VFR conditions will prevail into Mon morning
as high pressure influences the weather. Moisture will increase
across the region late Mon into Tue as low pressure tracks
across the area producing widespread rain subVFR conditions mon
night into tue. Improving conditions expected Wednesday with
the low lifting north of the area and drier air moving into the
region.

Marine
Short term through tonight ...

as of 2 am sat... Latest obs show variable winds NE to S 5-15 kt
with seas 2-3 ft. High pressure will continue to extend over
the waters from the north through the period. Flow becomes more
n NE 10-15 kt this morning, then more easterly late today and
tonight. Seas generally 2-3 ft.

Long term Sunday through Wednesday ...

as of 330 pm fri... Ne winds 10- 15 kt are expected Sunday as
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 15-20 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.

Winds become SW 10-15 kt Wed with elevated 7-10 ft seas
gradually subsiding to 5 to 8 ft late.

Mhx watches warnings advisories
Nc... None.

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.
