Synopsis
The remnant circulation of barry and its trailing surface trough
will depart into the western atlantic through tonight. High
pressure will build over the southeastern united states Friday
through the weekend. A cold front approaching from the great
lakes and pennsylvania will cross the region early next week.

Near term through tonight
Another hot and humid day is in store, but not quite as hot as
Wednesday given expected cloud cover and potential for scattered
to numerous showers and thunderstorms developing a few hours
earlier than yesterday. These factors should keep heat indices
in the 95-100 range, just a few degrees shy of headline
criteria, but still hot nonetheless.

There's less shear today, but still expecting around 2000 cape.

Overall, storm organization should be less, and coverage less
widespread. Heavy rain and perhaps some strong gusty winds are
still possible given instability and high pwats in place. One
concern is slower storm motions and a weak mesolow progged by
some guidance developing near i-95 later this afternoon, so if
any heavier thunderstorms re-develop over the same areas,
isolated instances of flooding could be an issue.

Warm and humid tonight with lows in the 70s and patchy fog
possible, especially in any areas that receive rain today given
decreasing cloud cover.

Short term Friday through Saturday night
Have opted to extend the excessive heat watch through Sunday
evening, and include the nighttime hours for multiple reasons:
1) multiple days with heat indices forecast to be near or above
warning thresholds (105 west of the blue ridge 110 east of the
blue ridge) during the afternoon hours, and 2) heat indices not
dropping below 80 for long (if at all) overnight, possibly
staying above 90 in the major urban centers, offering very
little relief from the heat. The prolonged and persistent nature
of the heat could prove to be even more dangerous than usual for
these reasons, even though the forecasted temperatures, dew
points and subsequently heat index values at any given hour on
any given day aren't necessarily unheard of for the mid-atlantic.

It is vitally important to plan ahead so you can beat the heat
late this week. Do not engage in strenuous activity during peak
heating (afternoon hours). Avoid prolonged exposure to the
heat, staying in air conditioned areas when possible. Drink
plenty of water and wear loose, light fitting clothing. Keep
pets in cool, air conditioned areas with plenty of water, and
avoid taking them outside during the day when pavement
temperatures are very hot. And do not leave pets or children
unattended in a vehicle.
