An Excessive Heat Warning, Heat Advisory, and Air Quality Alert are in effect today as temperatures again soar well into the 90s.

Here are your weather headlines for Monday, July 20, 2015...

Ferocious Heat & Humidity

Fans and air conditioners will be put the test once again today, as fierce heat and stifling humidity once again choke New Jersey. Today will be the second 90+ degree day of this 3-day heat wave.

Morning temperatures have only fallen to the upper 70s to lower 80s - a disgustingly warm start to the day. High temperatures look to rise to the 92° to 97° range for inland New Jersey today. Along the Jersey Shore, temperatures will climb to at least the lower to mid 80s (90° is certainly possible). As usual, the temperature doesn't tell the whole story - continuing high humidity will push the heat index ("apparent temperature" or "feels like temperature") to 100° for the second day in a row.

An Excessive Heat Warning is in effect for the Philadelphia metro area today, including Mercer, northern Burlington, Camden, and Gloucester counties. Most of the rest of New Jersey is under a Heat Advisory. And we're in a "Code Yellow" Air Quality Alert day, as ozone concentrations may be unhealthy for unusually sensitive individuals. It all boils down to potentially dangerous heat again today: please take care of yourself and each other, and consider amending your daily activities to accommodate the very hot weather.

Another warm, muggy night tonight with lows in the 70s will lead into one more hot, humid day tomorrow. We'll once again see widespread 90s on the temperature map Tuesday afternoon.

Stray Rain Chances

A pair of weak fronts will push through New Jersey over the next 48 hours and will combine with the heat (energy) and humidity (moisture) to bring scattered rain chances along the way. Today's front will be particularly subtle, so we'll just include a stray shower or thunderstorm chance throughout today and tonight for New Jersey.

Tuesday's front will carry a little more "oomph". I think we'll see a few showers and thunderstorms sweep through the state from about 7 p.m. Tuesday through early Wednesday morning. Not everyone will get rain here, but I could see a strong thunderstorm or two popping up in the warm, humid air.

Any Cooldown in Sight?

Behind the latter front, we'll see a slight cool down for Wednesday through the second half of the week. High temperatures should return to the seasonable lower to mid 80s.

More importantly, the arrival of drier air will lower dew points and make the humidity level MUCH more comfortable. That will be a big difference! In fact, the stretch of weather from Wednesday through Saturday looks quite pleasant.
