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 pm this evening
As of 500 am edt Wednesday...

very light isolated showers are still continuing to move off
the coast early this morning. Once the showers move off the
coast in the next couple of hours, the area will remain dry
through the morning. Temperatures will quickly heat up into the
90s with heat indices approaching 100 by mid-morning, before
rain begins to develop.

Short term 6 pm this evening through Friday
As of 500 am edt Wednesday...

hot conditions will be moving into the area for the rest of
this week and into this weekend. Today, temperatures will climb
into the upper 90s along i-95 and mid 90s elsewhere.

Dew points will also be in the mid to upper 70s, leading to
heat indices of 105-107 (mainly areas along and east of i-95,
including DELMARVA and NE nc). Showers tstms may pop-up along
the seabreeze for NE nc and hampton roads late in the morning to
early afternoon (pops 20-30%). Later in the afternoon, storms
will develop as the shortwave moves across the area. Highest
confidence for precip will be from richmond on northward, and md
eastern shore. Pw values will be greater than 2" across the
area, therefore storms will likely produce heavy rain. Tstms
will develop once again on Thursday as a trough remains in the
area. Temperatures won't be as hot with highs only in the mid
90s and lows in the lower 70s.

Friday and Saturday is when the excessive heat builds in. High
pressure aloft will build over the area as a sfc high off the
coast bring moisture up from the tropics. Highs will be in the
low 100s for the richmond metro and va piedmont and upper 90s to
near 100 elsewhere (low-mid 90s at immediate coast). These
temperatures combined with dewpoints in the 70s will give way
to heat indices of 110-115. An excessive heat watch may be
needed for fri-sun as this looks to be a prolong heatwave. In
addition, overnight lows will not provide much relief from the
heat. Lows will struggle to drop below 80, especially in the
urban area of the richmond metro and hampton roads.

Long term Friday 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 10z Wednesday through Sunday
As of 150 am edt Wednesday...

despite some lingering isolated showers from ric to orf,VFR
conditions noted across area terminals early this morning.

Sct-bkn mid and high clouds with a ssw wind of 5-8kt to continue
early this morning through midday, increasing to 8-12kt out of
the SW by aftn, with some occasional gusts to ~15-18kt possible.

We do have the chc for some additional isolated to widely sct
aftn evening showers tstms this aftn, mainly over SE sections
from phf orf ecg.

Outlook: very similar setup on thu, with a chance for additional
sct showers and storms Thursday aftn evening, dropping back to
20% or less Friday through Sunday. Predominate conditions will
remainVFR at terminals, with brief flight restrictions (mainly
due to lowered vsby) with any showers tstms.

Marine
As of 430 am edt Wednesday...

early this morning, sfc high pressure was centered well off the mid
atlc coast, while a trough of low pressure was pushing thru the oh
and tn valleys. This was resulting SW winds 5-15 kt over the waters
with waves and seas 1-2 ft.

The trough of low pressure will slide eastward toward the area this
aftn into tonight. This will tighten the gradient a bit and kick ssw
winds up to 10 to 15 kt in the ches bay, and 15 to 20 kt in the
coastal waters. This will build waves to 2 ft in the ches bay, and
seas to 3-4 ft on the coastal waters.

The winds will begin to relax to 5 to around 10 kt on the bay and
rivers, and 10 to 15 kt on the ocean waters on thu, as the trough of
low pressure slides over the area. This pattern will continue into
fri, allowing for a continued weakening of the winds to 5-10 kt.

But, once the weak trough breaks down, the bermuda high will once
again begin to build into the region and ssw flow will again
strengthen to 10-15 kt over most of the waters for Fri night thru
sun.

Climate
Upcoming heatwave may challenge or break record highs and or
record high lows (esp from Fri through sun).
