What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Dry weather is expected through Friday under the influence of
high pressure off the mid-atlantic coast. Low pressure over the
gulf of mexico will gradually bring a return of moisture for
the upcoming weekend, mainly in the form of afternoon showers
and thunderstorms.

Near term through Friday
As of 330 pm edt Thursday...

sfc high pressure (1022 mb) is currently situated off the
eastern shore with a cold front now down into central nc. Drier
air (dew pts in the 50s) have made their way into much of the
area with little to no afternoon CU to speak of. The offshore
high will set the stage for a great evening. Clear and
comfortable tonight with lows in the mid 50s to low 60s.

Modest increase in temps expected on Friday, as thicknesses
increase slightly and winds veer around to the SW as the surface
high shifts further offshore. MOS and local thickness tool
support highs into the mid to upper 80s (upr 70s low immediate
coast).

Short term Friday night through Sunday
As of 330 pm edt Thursday...

by Friday night into the weekend, we'll see the southerly flow
begin to bring more moisture back to the region as the surface
high slides even further off the coast and the deep tropical
moisture feed that is in place from the west caribbean gets
pulled farther north. Models are coming into better agreement
with respect to handling of the system currently near the
yucatan, with the GFS now trending west with the system similar
to the ecmwf. Even with the system heading more toward louisiana
we can still expect an increase in humidity locally, due to
sustained southerly flow from the gomex, and a mainly diurnal
chance of showers and thunderstorms both Saturday and Sunday.

Highs Sat Sun in the mid 80s, except slightly cooler immediate coast.

Lows from the mid 60s to low 70s.

Long term Sunday night through Thursday
As of 330 pm edt Thursday...

still much uncertainty with both the track and amount of
moisture associated with any tropical system next week. Both the
gfs ECMWF stall the system over the gulf coast states but
differ on the amount of moisture making it this far north. Ecmwf
keeps the deepest moisture south while the GFS shows periodic
atlantic and tropical moisture drifting north along a stalled
boundary across the region.

Upshot will be to keep pops in each day, highest across the south
and greatest chc for thunder during the aftn eve Mon tue. Pops
cont Wed Thu as the tropical moisture gets caught in the
westerlies and tracks ene. Highs upr 70s-mid 80s. Lows mid 60s-
lwr 70s.

Aviation 21z Thursday through Tuesday
As of 200 pm edt Thursday...

mainly clear through sunset with light nne winds. Skc tonight
with light and variable winds.VFR conditions continue Friday
with winds becoming ssw 10 kt or less.

Outlook... Expect moisture to increase for the upcoming holiday
weekend with scattered showers t-storms possible each
afternoon evening from sat-mon. Flight restrictions will be
possible in around tstms.

Marine
As of 330 pm edt Thursday...

no headlines as high pressure moves off the coast then dominates
through the holiday weekend. Nne becomes become S then SW as the
return flow sets up. Could see periodic south channeling in the ches
bay at times, but guidance consensus keeps the winds generally at or
below 15 kts. Seas 2-3 ft with 1-2 foot waves.

Hydrology
As of 330 pm edt Thursday...

a flood warning continues for the appomattox river basin. Expect
the river level will drop below flood stage by this evening. A
flood warning remains in effect for the nottoway river at
sebrell as the river will crest just above minor stage this
evening or tonight. Additional flood warnings continue for
portions of the mattaponi river and for kerr lake due to ongoing
road closure issues. See flwakq and flsakq for more details.

Tides coastal flooding
Levels should reach action stage and may approach minor flooding at
bishops head Friday night due to the south channelling.

Climate
As of 330 pm edt Thursday...

* ric monthly rainfall total through 5 23 is 10.25" which now
ranks as the wettest may on record. (breaking the old record
of 9.79" in 2016). (precipitation records date back to 1880).

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.
