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.

Watches & Warnings

Heat Advisory
Issued: 8:04 PM EDT Jul. 25, 2016 – National Weather Service

... Heat advisory in effect from noon to 8 PM EDT Tuesday...

* heat index values: 105 to 109.

* Impacts: prolonged exposure or any strenuous activity may lead
to heat related illnesses that require immediate medical
attention.

Precautionary/preparedness actions...

A heat advisory means that a period of hot temperatures is
expected. The combination of hot temperatures and high humidity
will combine to create a situation in which heat illnesses are
possible. Drink plenty of fluids... stay in an air-conditioned
room... stay in the shade if possible... and check up on relatives
and neighbors.

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 9 1 1.
