Excessive Heat and Humidity on the Way!

Well, today is another hot one in our area! Our current temperatures are still in the lower 90s at this time, but the fortunate news is that the humidity has been falling throughout the day. Current heat indexes are into the mid 90s to upper 90s in spots with the higher humidity. We do have to point out the cold front in our area that has been sinking south throughout the day. As a result, storms could develop anytime, most likely south of I-78 or so in our area. Tonight will be a nicer night with temps into the low to mid 70s with the lowering humidity with the skies going mostly clear during the overnight hours.

Tomorrow will be most likely the nicest day of the week with the lowest humidity and the lowest temperatures, although most areas will still top out near 90 deg in areas like Newark. If areas like Newark do reach 90 deg tomorrow, you will still be continuing your heat wave. The lower dew points and temperatures will probably not be enough to bring significant heat relief....that may not happen until Sunday or Monday, but the GFS and EURO models still have to determine the day our heat wave will end, which will be discussed later in this blog post. For Wednesday night, the humidity will be increasing with temps only dropping to the mid 70s.

Thursday, the humidity will be increasing into the 70s as the worst of this heat wave rolls through our area, making the temperatures feel much warmer, possibly over 110 deg! As a result of a storm system passing through areas north of our region, we will have some clouds building. The heat and humidity will last through Friday, maybe even through Saturday depending on when the cold front arrives. For Thursday and Friday night, there is a possibility that the nighttime lows may have to be raised to around 80 deg, but those details are being worked out at this time. Nonetheless, it will be very uncomfortable at night with the lows so warm. Even heat indexes will remain in the mid to upper 80s all night, contributing to the uncomfortable heat.

The toughest part of this forecast will be when the heat will actually end. As I mentioned earlier, the day we forecast the heat will end will depend on the trend of the GFS and Euro models. At this time, the GFS model is quicker pushing the cold front through which would mean a quicker end to this heat wave, probably on Saturday. However, the EURO model has a slower solution on when this cold front will move through, which will probably be on Sunday according to the EURO model. It seems like we're leaning towards the EURO model more than the GFS, although we are in middle-ground with this forecast. Either way you slice it, it will be very warm this weekend, but how warm???? More details to come.
