What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Wakefield, VA wrote its last area forecast discussion before this special weather statement went out at Aug 2, 1:50 PM EDT, 10 minutes earlier.

Area forecast discussion, Aug 2, 1:50 PM EDT, 10 minutes before
Area Forecast Discussion
National Weather Service Wakefield VA
150 PM EDT TUE AUG 2 2016

.SYNOPSIS...
A weak frontal boundary will drop from southern Virginia south
through North Carolina today through tonight, as high pressure
builds from the Great Lakes into New England. That high will slide
off the New England coast Wednesday through Thursday, as the
frontal boundary will linger across the Carolinas and offshore.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Updated forecast for the afternoon to reflect shower activity
developing along slow moving frontal boundary, which is bisecting
the area at midday. High PWs, deep warm cloud depths and lingering
mid level cap will serve to favor moderate to heavy showers vice
thunder...but better chances for thunder remain in for the
afternoon across the southern half of the area.

Highs a bit cooler than previous days...low to mid 80s north and
coastal sections, mid to upper 80s south central VA/interior NE
NC.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/...
Late this evening into Wed morning, chcs will diminish to 20-30%
acrs srn/sw counties, as the boundary pushes farther s into NC,
and high pressure blds into New England. Mostly clear to mostly
cloudy tngt with lows in the upper 60s to lower 70s.

Latest model runs (00z/02) show high pressure sliding off the New
England coast Wed thru Thu, as the frontal boundary lingers acrs
the Carolinas and offshore. Thus, have tweaked the fcst a bit,
especially acrs the srn/sw counties where deeper lo level
moisture will remain along with possible lo level convergence and
lift, which may result in isolated or sctd showers or tstms.
However, still expect dry conditions acrs nrn/ne counties Wed and
Thu with more sunshine and more comfortable humidity. Highs will
average in the mid 80s both days, with lower 80s along the Atlc
coast of the Ern Shore. Lows Wed ngt will range fm the mid 60s to
lower 70s.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Surface high pressure off the New England coast is expected to
push out to sea Thu night/Fri as a sfc low crosses nrn Ontario.
This feature is expected to drag a cold front through the Great
Lakes and Ohio Valley Fri...then cross the Mid Atlantic Region
Sat/Sat night. The front is now showing signs of stalling over
the Carolinas on Sun. Meanwhile, a large scale upper low
traverses the SE half of Canada...potentially bringing cooler
temps and maybe even some clouds to the area in nw flow aloft. A
little too soon to hash out these exact details, but this would be
enough to shunt the frontal boundary south of the area as progged
by long term model solutions. Little to no changes have been made
to ongoing temp/precip forecast. Overall, aftn/evening
thunderstorms possible Fri-Sun.

With sfc high pressure shifting ewd and away from the New
England/Atlantic coast, temperatures and dewpoints/humidity will
begin a gradual warming trend Fri through the upcoming weekend.
Lows Thu night around 70F inland/lower 70s beaches. Highs Fri
in the upper 80s inland/low-mid 80s beaches. Lows Fri/Sat nights
70-75F inland/mid-upper 70s se beaches. Highs Sat/Sun in the
lower 90s inland/mid 80s beaches.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
As of 17z...A weak frontal boundary was moving to the south through
southeast Virginia. Scattered thunderstorms were developing along
the boundary mainly affecting PHF and ORF. The boundary will
continue moving to the south. Convection should remain south of
RIC ard SBY. Will need to monitor for thunderstorms through this
evening southeast portions.

Brief periods of IFR and gusty winds can be expected with the
thunderstorms. Some MVFR conditions are possible Wednesday morning.
Thunderstorms will be possible far southern portions on Wednesday.

OUTLOOK...The front stalls over the Carolinas. Most of the
convection should remain to the south through Friday. Scattered
thunderstorms are possible over the weekend.

&&

.MARINE...
A sfc frontal boundary was situated ovr the nrn bay/ocn waters at
06z/02. Wnds NNE N of that boundary...WSW S of it (speeds mnly aob
10 kt). That boundary fcst to settle S acrs the rmng waters
through 00-06z/03...w/ the hi res guid placing it invof the nrn
NC wtrs by lt tngt. Long pd (through Thu) of onshore (ENE) wnds
expected. Some slgt increase in speeds (to 15-20kt) mnly on the
ocn wtrs (mnly on Wed). Sfc hi pres retreating E of New Eng by lt
wk will bring a gradual end to the onshore wnds. Seas avg 2-3ft...but
may build to 4ft fm 10-20nm in the persistent onshore flo Wed into
Thu. Waves avg 1-2ft in the bay/snd...though pds of 3 ft psbl
invof the mouth of the bay.

&&

.TIDES/COASTAL FLOODING...
Due to persistent pd of onshore wnds...tidal levels w/ be on the
increase...w/ a few locations potentially reaching within 0.5 ft
of minor flood thresholds (Wed-Thu).

&&

.CLIMATE...
6.98 inches of rain at ORF yesterday set a daily record rainfall.
This appears to rank as the fifth highest calendar day total on
record for ORF.

Another climo note for Norfolk: Per monthly climate, July 2016
will go down as 6th warmest month on record at ORF.
