I certainly hope everyone fared well with yesterday's severe weather event. Those storms were INTENSE! I was driving home from the in-laws in Toms River and boy was it every a LIGHT SHOW. At one point lightning struck the ground 10 feet away from the car. Terrifying - but in a beautiful kinda way. Call me crazy.
Dew points at this hour are in the 40s but are expected to drop even MORE overnight. This is what is ushering in that cool, refreshing, fall-like feel. The lower those numbers are, the cooler the air feels - certainly more comfy. So why is this happening all of a sudden?
Obviously our weather pattern here in South Jersey is highly variable. We see swings all the time. It's normal. What you're looking at above is the 500mb chart. This shows what's going on above our heads over 15k feet up. Blue is a dip in the jet (trough) while orange/red is a rise, or ridge in the jet. When you see blue over our area, it means we've got a generally cool airmass in place. So cool that we could get into the low and mid 40s through the pine barrens tonight!
I mentioned this last night and I was challenged by someone. And that's GOOD. It means you're paying attention. I was challenged because none of the forecast models were showing lows in the 40s. This is where HUMANS are still needed to determine what's going to happen. When you have clear skies, no wind and low dew points, air temps are able to cool off rapidly. Dry air is able to cool much faster than moist air since water retains energy. This is why I believe that SOME of you may get to 42-44. Crazy, right? The record to beat at ACY is 42. That will be hard in Eastern Egg Harbor Township, but could come close in other places.
