While dangerous heat will hold in the South, a dose of hot and humid conditions will reach the Ohio Valley and Northeast this weekend and into next week.
A large and strong area of high pressure anchored over the South Central states will bulge enough to send near-90-degree Fahrenheit air northward.
In many cases, temperatures will surge to 5-10 degrees above average during what is typically the hottest part of the summer.
The combination of heat, high humidity, sunshine and light winds could pose problems for those partaking in extended strenuous physical activity and those with respiratory problems.
Excessive Heat, Humidity to Swelter South This Weekend
According to AccuWeather Senior Meteorologist Dave Dombek, "Actual temperatures in parts of the mid-Atlantic states could still challenge their highest mark so far this year, which was during the middle of June in most locations."

Much of New England will stop short of 90. However, highs will reach or exceed 80 in many areas with RealFeel Temperatures well into the 80s and middle 90s.
The warmth will allow some people to hit the beach or hang out at the pool.
The only deterrent to non-strenuous outdoor activity will be the threat for thunderstorms.
The bulk of the storms will occur north of Tennessee and North Carolina as well as over Florida, with a few exceptions.
In much of the Southeast states, actual temperatures will not be quite as extreme as that of the second half of June. However, the combination of actual temperatures reaching well into the 90s, high humidity, little wind and strong mid-July sunshine will push RealFeel Temperatures to well over 100. In terms of RealFeel Temperatures, this swelter could be worse than that of late June.
Cities in the Southeast set to broil into next week include Atlanta; Nashville; Birmingham, Alabama; Charlotte, North Carolina; Columbia; South Carolina; and Richmond, Virginia.
AccuWeather RealFeel® Temperatures From Thursday, July 16, 2015
Over the next several days the Dallas/Fort Worth Metroplex is likely to reach 100 for the first time this year and could do so on multiple dates. There have only been a handful of years where the temperature has not hit 100 in Dallas since the late 1800s.
It is very easy to be overcome by the heat this time of the year. If you must work outdoors, be sure to take frequent breaks and increase your intake of water and electrolyte balancing fluids.

Oh,
and also, many were freaking out about the forecast for a wet july with
a parade of thunderstorm across the ohio valley and mid atlantic...and
thy Reverend didst warn yes of a great hysteria that wast developing,
not entirely dissimilar to that which we didst experience in Salem many a
year ago....anyways, my point is proven that if a forecaster has
disappointed you in their forecast for a warm and dry summer, when they
then call for a wet period, the disappointment then works in your favor.
The chill of late March ended early, as did the chill of late April, as
did the May warmth, as now it seems the july rain will as well.
Cottone Mathere
LOL...everyone
was freaking out about it being the coldest summer in the history of
the world...and now it is getting hot...could it be ANOTHER mid July
pattern change, JUST LIKE last year? Could it be that the weather
patterns actually have an ebb and flow to them, and that I am not full
of hot air? (no pun intended -- well, actually, it was
intended...)...anyways, maybe not an actual pattern change, but no ice
age. At least not til 2030 -- ha ha ha.

Verily
thou speakest well. I be sorely vexed by some forecasters when they
soothsay, as it doth seem sorely ludicrous when the prognostications be
made weeks ahead.

So don't exercise when it's humid outside period!
Cottone Mathere
Ann, only because of the dumb decisions people make. Hot weather isn't really more dangerous.

What
makes this upcoming cold season hard to figure is there is still a near
record warm "bubble" in the EPAC which is a cold signal for the east.
How this reacts with this strong El Niño should be interesting
Cory Morrison ·
I
think this could result in a pattern similar to the last 2 winters, but
that the brunt of the below normal temps would be farther south than
the last 2 winters, meaning that the cold won't be quite as severe for
the Midwest/GL/Northeast compared to the last 2 winters.
Cottone Mathere
The
interesting thing is, the PDO was supposedly positive in the '80's and
'90's, but the east had warmer winters. And warmer el nino winters, even
when the el nino's weren't that strong.
Wayne Langhuber ·
My
long range forecaster at EPAWA is saying the rest of July will be above
normal in the east. So far this month we are about 1.5 degrees below
normal. I think that the rest of the month will offset that so we end up
normal. We have had alot of warm/humid days but some cloudy days that
have held off the heat. The pattern is changing. Today will be the last
comfortable day in Eastern Pa for perhaps the rest of the month. Sat-Mon
look like a three day heat wave with dewpoint temps near 70-72. Heat
Index high 90's to near 100. Next Tues-Thurs we cool off a bit to the
upper 80's and moderate humid...See More

1997-98
was an east-based El Nino. Right now, this El Nino looks to be
east-based, but I read somewhere that regions 1+2 may have cooler
anomalies into the fall and winter but region 3.4 may have warming
waters. This would suggest a central-based El Nino similar to 2009-10
but hopefully not as brutal as the last 2 winters.

Cory
Morrison 2009-10 probably see worse weather where I live than where you
live. We were in the "Sweet Spot" for heavy snowstorms. We only had
four but they totaled 55 inches. Philly got 78 inches from those 4
snowstorms. As far as cold Dec was slightly below, Jan normal and Feb
below. However February was not extreme. I suspect snow cover held down
the temps. Most days saw lows around 20 and highs mid 30's. And because
there was no sleet/ice issues clearning the roads was pretty easy. They
just piled the snow on the Lancaster county farmland and waited till
March when it melted. That very ...See More

In
those 20 years from 1988-89 to 2007-08: 1993-94, 1995-96, 2002-03, and
2003-04 were those 4 colder than average winters where you are?

It's
about time! This summer was looking like one of the coldest on record
around here. Though it might've hit 90 a couple of times in NYC,up here
in the suburbs the closest we got is a couple of days that it hit 88
degrees either in White Plains or Yonkers and today it was 75 degrees IN
MID-JULY. Usually at this time of year for it to be 75 for a high it
has to be raining and/or thunderstorming and cloudy most of the day yet
we had wall-to-wall sunshine today and it still only got to 75 or 76
degrees. Proves that the Jet-stream is hanging too far to the south this
year to be normal,allowing unseasonably cool, Canadian air to come in.
To use a popular term that's been bambied about lately, we shouldn't be
having Polar Vortexs in the middle of the summer. That's just crazy. Add
in the frigid,brutally cold winter of 2014-15 and 2015 is looking to be
one of the coldest years on record for this area if the second half of
this summer doesn't end up being a real sizzler around here.
Cory Morrison ·
Good
points, though you still have September, October, November, and
December to be above normal to prevent 2015 from being the coldest year
on record in your location (Not that I actually think this will happen, I
am just stating the possibilities).
Neven Prvinic ·
William,
you said exactly what i wanted to say about this summer and 2015. We
are suffering an exact same fate here in Cleveland OH. We pride
ourselves with warm to hot and warm to hot summers, but not as opressive
as southern areas, but this year i have to apologize for our weather
and for living here to people from out of town that are visiting.
Grant McGuire ·
I
have to laugh at Accuweather's amazement: "Much of New England will
stop short of 90. However, highs will reach or exceed 80 in many areas
with RealFeel Temperatures well into the 80s and middle 90s." Really?
80s in mid-July? So astonishing!
Phil Derasmo ·
Ah
but u choose to ignore that meteorological summer is only about half
over there's plenty of time to reach the 90s even through September
Cory Morrison ·
I
read "Coolest Summer Ever" on the ad and it scared me at first, then I
realized "Oh, it's just for Disney World. Nothing to do with the
weather".
A few NYC weather facts:
(1) We haven't seen 90 in 23 days (and it's mid-July).
(2) We haven't had a heatwave in 2 years.
(3) We're on track for the fewest number of 90-degree days in recorded history.

Paul Berger But why does it also have to get humid with the 90 plus degree temps in NYC?
