Record highs are possible for parts of the Northeast Monday and Tuesday, as parts of the central U.S. take a little breather from the worst of summer's dog day heat.

Expansive high pressure in the upper atmosphere will focus on parts of the East and West this week, sending heat indices well into the triple digits from the Mid-Atlantic states into the South.

Heat Advisory
Issued: 3:38 PM EDT Jul. 25, 2016 – National Weather Service

... Heat advisory remains in effect until 8 PM EDT this evening...

* heat index values... up to 110 this afternoon due to
temperatures in the mid 90s to around 100... and dewpoints in the
70s.

* Impacts... risk of heat-related illness for those without air-

Precautionary/preparedness actions...

A heat advisory means that a period of high temperatures is
expected. The combination of high temperatures and high humidity
will create a situation in which heat illnesses are possible.

Take extra precautions if you work or spend time outside. When
possible... reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work... the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency - call 911.
