Heat advisories have been expanding across the country as we prepare for dangerously hot temperatures. For some, heat index values could reach 105+ degrees!
We're still tracking a large ridge of high pressure. Previously, heat alerts were in effect across the Central Plains. This ridge eventually shifts East, and cities along the I-95 corridor could feel some of their warmest temps of the season.

Newly issued Heat Advisories have been issued into the Tri-State area. This includes New York City and the Philadelphia metro areas. These are in place for Thursday, where heat index values will make air temperatures feel as hot as 100 degrees.


Heat Advisories have now also been issued for portions of the Bay Area and Central Valley; temperatures up to the triple digits are expected here as well.

As for the Pacific Northwest the warmest air of the year will impact Portland on Sunday & Monday!
