Good Wednesday morning to you, South Jersey. Normally, I'd also say "Happy Hump Day" and begin my discussion, but with today being what it is, I feel that we should all take a moment to reflect on the events of 12 years ago, remember those who were lost on that fateful day, and be thankful for how far we've come since then. So wherever you may be or whatever you may be doing, please...just take one moment to remember.
With that said, let's focus on today's weather. To sum it up simply, it's going to be hot today. High pressure to our south will move to the east, and the associated ridge in the jet stream will also move eastward. This places us on the warmer western side of this area of high pressure, and our winds (Which will be out of the southwest both at the surface and further in the atmosphere) will carry plenty of warm and moist air from the Gulf of Mexico right into our backyard. With ample sunshine, increasing dew points, and high humidity, heat index values will climb well into the mid 90s throughout the region. High temperatures themselves will hit 90 on the mainland and the mid 80s on the coast with a light southwest wind at 5 to 10mph. Please be sure to stay cool today if you are attending any of the 9/11 remembrance ceremonies. There will be little to no relief tonight as well, with lows only reaching the low to mid 70s with a light south wind. Dew points remain high, making things rather uncomfortable even in the dead of night. A change begins to occur on Thursday. A cold front that is currently in the Midwest will pass through the region late on Thursday and into the night. Ahead of it, the pre-frontal air mass will interact with the pre-existing warm and moist air mass that we are experiencing as I type. As a result, there is the chance for some scattered showers and thunderstorms...some of which may be stronger in nature. Highs will take a step back with increased cloud cover, but we'll call it partly cloudy overall. Temperatures will climb into the mid 80s on the mainland and low 80s on the coast.
An isolated shower before sunrise is possible on Friday as that cold front moves off the coast. Once it does, high pressure out of Canada will move over the Northeast and stay put through the weekend. Highs begins a more substantial descent for the end of the work week with gradually clearing skies and more comfortable conditions as well. Highs in the mid 70s on the mainland and low 70s on the coast. The core of this cold air arrives on Saturday, with some of the coolest forecasted temperatures we've seen in a long time. It will be a struggle to reach 70 degrees on the mainland (let alone the coast) with a strong northwesterly flow in place. Plenty of sunshine can be seen on Saturday and Sunday as we warm up slightly...back into the low to mid 70s to be more exact. We'll keep an eye on a weak cold front for the start of the work week, but we'll keep the forecast dry for now with partly sunny skies and highs expected to remain in the mid 70s.
Take care, and have a great day!
