More Heat In An Already Hot Stretch Of Weather

Posted: Updated:

Good Thursday morning to you, South Jersey! It's as if the record player that is our weather is skipping on the same track: Hot and humid. That has been the case over the last four days, and today will make it five days. High pressure to the west is slowly beginning to drift to the south and decay as well, and this will serve as a catalyst for a rather significant pattern change coming up in a few days. Until then, we must continue to deal with this long-standing heat wave. Heat advisories are up for southeastern Burlington and Ocean county until 8pm today, and an excessive heat warning is up for Gloucester, Camden, NW Burlington, and Mercer county through Saturday. No heat advisories are up for South Jersey and Salem county as of this post, but that may change later today. Air quality alerts are up for everyone today due to poor air quality levels caused by an increased concentration of pollutants in the atmosphere. The cause? The "dome" of high pressure that has been over us this week. It causes air to become stagnant, allowing for such an accumulation. Please be sure to take it easy outside. So for today, once again, we're hot and humid with highs in the mid to upper 90s on the mainland and 90 degrees on the shore with a southwest wind at 10mph. An isolated thunderstorm is possible as a weak impulse passes through the area. Otherwise, we're partly cloudy and uncomfortable tonight with lows in the mid 70s and a light southwest wind at 5mph.

As our core of high pressure decays and moves southward, that will allow a cold front that is currently in Canada to move to the south. It is expected to interact with that plethora of warm, moist, and unstable air already in place over the Northeast, which will bring about the threat for some stronger storms. That WON'T be the case on Friday...that front will remain in northern New England. We DO, however, still have the chance for a late day isolated thunderstorm on Friday evening. Otherwise, we remain mostly sunny, hot, and humid again with highs in the mid 90s west of the GSP and upper 80s on the beach. All eyes remain on Saturday, primarily on the evening time frame. That, for now, is the running consensus for when this front is expected to approach as well as the time when thunderstorms of a stronger variety may begin to form. I know everyone is anxious about the Saturday forecast...especially anyone in Ocean City. Well, the day appears to remain mainly dry, but we can't overlook the threat for some thunderstorms later in the evening. Dan, Sydney, and I will have you all covered. At any rate, I think one more 90 degree day is likely on the mainland, while the coast is in the mid 80s for high temps. The front is expected to stall just off the coast, allowing for some lingering storms to pop up on Sunday. Otherwise, we'll see partly sunny skies and slightly more comfortable conditions. Highs in the mid 80s with dew points "only" in the mid 60s. We get a brief break on Monday and Tuesday before a few more storms are possible on Wednesday. Thankfully, highs remain in the 80s.

Stay cool, stay safe, and have a great day!
