Just in case some people don't know here's Upton's criteria for heat related advisories and warnings.

 

Excessive Heat Warning
Issued when heat index values are forecast to reach or exceed 105°F for at least 2 consecutive hours.

Heat Advisory
Issued when maximum daytime heat index values are forecast to reach 100 to 104°F for at least 2 consecutive hours.
NOTE: For New York City, a Heat Advisory is issued when the heat index is forecast to reach 95F or greater for at least 2 consecutive days or 100 to 104F for any length of time.
