Synopsis
Somewhat drier air will prevail this afternoon before another
round of increasing moisture returns Monday through Wednesday. A
period of dry weather looks promising by Thursday and Friday.

Near term until 6 pm this evening
As of 1015 am edt Sunday...

the widespread ra of the past few days has ended. SW flow has
taken over and will continue through this afternoon... Resulting
in a drier day (at least wrt pops). Expecting vrb clouds-partly
sunny conditions... Have gone W a bit lower pops (to 15-30%) for
this afternoon as heating will be the main trigger. By this
eve... A slight uptick in pops possible INVOF sfc trough over nnw
portions of the fa and INVOF lingering moisture axis in SE va-
ne nc. SW winds will average 10-20 mph... Bit gusty at times to
25 mph. Highs in the m-u80s... Even around 80f at the beaches.

Short term 6 pm this evening through Tuesday
As of 1015 am edt Sunday...

but by the evening high res models are suggesting a secondary
area of showers tstms develops moves in from the wnw and have
20-30% pops moving through all areas. Partly mostly cloudy
tonight with lows mainly from the mid 60s to around 70 f.

On mon, will see some weak onshore NE flow develop for awhile
along the coast, but by aftn as the flow aloft shifts from the
w to the wsw... Expecting increasing moisture ahead of the next
approaching systems from the S and w. Partly sunny- mostly
cloudy W pops by afternoon rising to 30-50% inland in the
afternoon... 10-30% toward the ERN shore. SPC has marginal risk
svr now staying off to the NW of the local area. Highs in the
70s at the coast to the low- mid 80s inland.

Warm front pulls N of the region Mon night (w possible sct
shras-tstms)... And will have 40-60% pops all areas. Sfc high
pres off the SE CONUS coast remains in control tue. Low pres and
its accompanying cold front tracks through the midwest- oh
valley tue. Vrb clouds- partly sunny Tue W mainly diurnal pops
(20-40%) (tue) ahead of that system, but pops have been
increased later in the day W decent feed of moisture and lift
noted by latest nam GFS 00z runs. Lows Mon night in the low 60s
on the lower md ERN shore to the m-u60s elsewhere. Highs tue
from the m-u70s at the coast to 80-85f inland.

Long term Tuesday night through Saturday
As of 240 pm edt Saturday...

a respite from the wet wx pattern suggested by most extended
models for mid-late in the upcoming week. Just enough of a nw
flow aloft suggests that drying will take place after Wed and
last into next weekend. Lo pres passing by N of the region tue
night-wed will push a cold front (possibly accompanied by
shras tstms) E and S of the local area. Hi pres is then expected
to build into the region for thu-fri. By next sat... A return
flow from the ssw to set up potentially resulting in increasing
moisture gradual rise in pops.

Lows Tue night in the m-u60s. Highs Wed in the 70s-around 80f
at the coast to the m80s inland. Lows Wed night in the l-m60s.

Highs Thu from the u70s-m80s. Lows Thu night mainly 60-65f.

Highs Fri 80-85f... 70s at the immediate coast. Highs Sat in the
m-u80s inland... U70s-l80s at the coast.

Aviation 14z Sunday through Thursday
As of 800 am edt Sunday...

still some isolated scattered showers that may affect SE sites
through about 14 15z this morning, otherwise mainly MVFR cigs
early will lift scatter out toVFR conditions prior to noon most
areas. A SW of 8-12 kt is expected, with occasional gusts to
20kt possible. There is a 20-30% chc of showers tstms this aftn,
mainly towards the SE va NE nc coast. Another area of scattered
showers isolated tstms will be possible as a weak frontal
boundary drops through tonight. Still not really expecting
anything widespread but some brief flight restrictions will be
possible mainly from 00-06z N to 06-12z south. Could also see
some CIGS lowering towards sunrise on Mon but confidence in
that scenario is rather low at this time.

A chc of aftn evening showers tstms will continue Monday through
Wednesday. A moist airmass will remain over the region and a
potential will exist for patchy early morning fog and or
stratus. High pressure may build in from the N by Thursday.

Marine
As of 415 am edt Sunday...

ssw winds were mainly 10-15 kt with a few gusts to 20 kt early
this morning acrs the waters. Winds will become SW later this
morning into this aftn at 5-15 kt. Seas will be 3-4 ft, except
4-5 ft north of parramore island into this evening, where a sca
remains in effect. Waves 1-3 ft this morning, then 1-2 ft by
tonight. Another frontal boundary will drop into at least northern
portions of the area late tonight into Mon morning, but NE or e
winds will remain around 10 kt or less over the northern waters.

Thus, am expecting seas to remain between 2-4 ft on mon, with
waves fm 1-2 ft. The frontal boundary lifts back north of the
region Mon night into Tue morning, with winds becoming S 5-15 kt
during tue. SW winds 5-15 kt expected late Tue night into wed
morning. A cold front then drops through the region Wed night
into Thu morning, with winds turning northerly.

river, and rawlings on the nottoway river. Flood warnings continue

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.
