Special Weather Statement, NWS Wakefield, VA

AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
356 PM EDT Tue Jul 16 2019

.SYNOPSIS...
High pressure will remain off the Southeast coast through
Wednesday. A weak trough of low pressure will cross the region
Thursday. Otherwise, hot and humid weather will continue until
Monday.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
As of 325 PM EDT Tuesday...

ISOLD-SCT tstms have been popping up the past couple of
hours...and are expected to persist into this evening...likely
waning w/ loss of heating. Heat advisory will remain in place
for SE VA-NE NC through 22Z/16 (though may trim early where
tstms persist). Heat indices have reached 105F (unofficially)
at ORF/ECG/AKQ this afternoon. Otw...mainly SKC and humid w/
lows ranging through the 70s.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY/...
As of 325 PM EDT Tuesday...

While remnants of a tropical cyclone pass well N of the region
Wed-Wed night...sfc hi pres becomes reestablished off the mid-
Atlantic/SE CONUS coast. SW flow pushes hot and humid air into
the region Wed w/ only minimal (diurnal) rain chances. Highs in
the m-u90s inland...l90s at the (immediate) coast.

Before (even) hotter wx arrives (for Fri-Mon)...a weak trough
aloft will be crossing the region Wed night-Thu which potentially
causes another increase in convection. Otw...partly cloudy w/
lows Wed night in the l70s W to the m-u70s elsewhere. Highs Thu
in the l-m90s.

Heat advisory has been raised for areas along/E of I 95 for Wed
for heat indices reaching around 105F. Dew point forecast is
tricky on Wed given potential for a bit of lowering (due to SW
winds) before/around the time of peak heating but that may
result in a bit higher actual temperature. Heat advisory may be
necessary again Thu...esp over SE VA-NE NC.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
As of 240 PM EDT Tuesday...

Not much to say (that hasn't already been conveyed) about the
upcoming heatwave Fri into early next week (Mon). A typical mid
July/summertime wx pattern persists through the extended
forecast period as (stagnant) hi pres sfc- aloft builds from the
SE/mid-Atlantic states on W through the mid MS valley.
Confidence is very high right now that this will be the hottest
period of the summer so far and result in dangerous heat
indices. Mainly partly cloudy...hot/humid during the day...very
warm/humid at night through the period (w/ aob climo diurnal
PoPs (blo 30%) - except a bit higher by Mon). Highs Fri in the
90s...then highs Sat and Sun mainly 95-101F - locally u80s-l90s
at the immediate coast each day. Heat effects will be cumulative
through the period as nighttime lows will avg 75-80F.

Heat advisories (heat indices 105-109F) and/or excessive heat
warnings (heat indices 110F+) are likely Fri through next
weekend (dependent upon future dew point forecasts). Will
continue to highlight this potential in the HWO. Record highs
may be tough to reach but record high lows appear to be
attainable...see CLIMATE below.

A breakdown of the hot pattern is showing up on the extended
guidance Mon through Tue as the heat ridge weakens and a trough
aloft begins to amplify toward the ern CONUS. Highs still in the
90s Mon w/ PoPs to 40-50% ahead of an approaching cold front.
Timing of that front completely through the FA remains uncertain
but it does appears that Tue will begin the cooldown in earnest
(w/ continued relatively high PoPs). Highs Tue in the u80s.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
As of 115 PM EDT Tuesday...

Mainly VFR conditions are expected through the 18Z TAF forecast
period. ISOLD-SCT tstms are expected into early this evening...have
included VCTS for ORF/PHF/ECG due to stms popping up INVOF SE
VA-NE NC. Winds generally SSW winds aob 10 kt. The chc of
showers/tstms will diminish overnight w/ only a 20% or less chc
of showers/tstms Wed. The chc for showers/tstms bumps up
slightly to 20-30% Thu afternoon/evening and then drops back to
20% or less Fri and Sat.

Brief flight restrictions (mainly due to lowered VSBY) are
possible w/ any stms the next several days.

&&

.MARINE...
10
As of 345 PM EDT Tuesday...

Overall winds are generally light 5 to 10 kt from the South this
afternoon as a weak areas of high pressure slides farther off
shore and a weak trough of low pressure is over Western Virginia
in the lee of the mountains. There are some isolated storms are
moving off shores in the Bay and coastal waters from the Bay
southward. In these showers some gusty winds to around 30 kts
are possible. These showers should dissipate by early evening.
After that the winds will return to a southerly to southwesterly
component but increase to around 10 - 15 kt as the Bermuda high
begins to briefly reestablish control of the weather along the
eastern seaboard.

A trough of low pressure over the Ohio Valley will begin to
push eastward into the area Wed afternoon into Wed night. This
will tighten the gradient and kick winds up to 10 to 15 kt in
the Bay and 15 to 20 in the coastal waters. Some of the wave
guidance suggest a short period of waves up near 5 Ft in the
northern coastal waters. For now have held values at 3 to 4 Ft
for last Wed into Wed night. Overall not raising any SCA Flags
through Wednesday night.

The winds will begin to relax to around 10 kt on the Bay and
rivers and 10 to 15 kt on the ocean waters on Thursday as the
trough of low pressure slides over the area. This pattern will
continue into Friday allowing for a continued weakening of the
winds to around 10 kt, but once the weak trough breaks down,
the Bermuda high will once again begin to build into the region
and the southerly to southwesterly flow will again strengthen to
around 10 to 15 kt for the coming weekend.
