Feeling tropical Thursday: Not as hot, very humid, scattered rain
Thursday morning is starting off steamy, with temperatures in the 70s. High temps will be limited to the mid 80s Thursday afternoon. But when you factor in the very high humidity, the heat index ("feels like" temperature) could reach 95 degrees. Uncomfortable.
In addition, scattered showers will continue to impact the Garden State Thursday.
Heat and humidity surge again Friday, as high temperatures return to the lower to mid-90s (away from the coast). With dew points still in the 70s, the math puts our heat index as high as 105 degrees. An isolated thunderstorm will be possible Friday evening — best chance is far northern NJ.
As we've been discussing for days, conditions this weekend are going to be downright dangerous. Saturday's high temperature will be very close to the 100-degree mark. Even the Jersey Shore will pop well into the 90s. Top heat index numbers will be about 110 to 115. Skies appear partly sunny, and I can't rule out a popup thunderstorm at any time in that hot, humid air mass. (Especially if a prominent sea breeze front sets up, that could serve as the impetus for a few tiny thunderstorms.)
More of the same for Sunday, with sweltering sunshine, highs near 100, and a heat index around 105 to 110.
An Excessive Heat Warning continues for the Philly metro area — Mercer, NW Burlington, Camden, and Gloucester counties — until Sunday evening.
Yearning for cooler weather? The end of this extreme heatwave is in sight! A batch of rain Sunday night will precede a cold front on Monday. That will finally open the door to cooler, much less humid air.
But here's the thing. That front is going to stall (get stuck) just south of New Jersey, and serve as a highway for clouds and rain for much of the week. I'm actually thinking temperatures will be held below seasonal normals, closer to 80 degrees. What a difference from this week's intense heat and humidity!
Don't think we're done with heat and humidity after this week though. Still a lot more summer to come...
