Good Tuesday morning, South Jersey! If you enjoyed yesterday's cooler temperatures (And believe me, I did), you're unfortunately out of luck for a while. Fall doesn't officially begin until September 22nd, and the next three days will act as a reminder that we are still in the summer season for about two more weeks. A warm front lifted to our north over the course of last night, and as it did, we saw our winds shift from a cooler easterly direction to a warmer and more moist southerly direction. At the same time, high pressure to our south has been moving towards the coastline, putting us in the warm sector, or the western side, of that associated ridge. That one-two combination will aid in warming us up considerably, especially when you compare it to the 75 degrees we felt yesterday. Skies will gradually clear through the rest of the day, and dew points will also rise. Highs will climb into the mid 80s on the mainland and low 80s on the beaches with a light southwest wind at 5 to 10mph. When you factor the dew point (Expected to be in the upper 60s) into the mix, heat index values will approach 90 degrees. There is little to no relief for us tonight, as we remain under the influence of this rather tropical feeling air mass. Lows only drop into the low 70s under partly cloudy skies. Winds will remain light and out of the south at 5 to 10mph. Our warmest day of the forecast comes around on Wednesday. Skies remain partly to mostly sunny, and with the southwesterly winds at the surface and in the atmosphere continuing to bring up warm air as well, this will be our best chance at reaching 90 degrees on the mainland...something that has only happened once since last July's eight day heat wave (That occurred on August 9th). The coast should remain in the mid 80s.
Though Thursday won't be as hot as Wednesday, we'll still feel just as muggy and uncomfortable with dew points remaining at the 70 degree mark. What we'll need to watch is an approaching cold front that will sweep through the region later in the evening and into the overnight period. This will hold our best chance for scattered showers and thunderstorms, and a few of these may have heavier periods of rainfall. Highs will reach the mid to upper 80s on the mainland and low 80s on the coast. Behind this cold front is a rather strong push of cooler, drier, and more comfortable air from Canada. High pressure will clear us out through the day on Friday with highs in the seasonably cool range of the low to mid 70s across the board. The core of this cool air hits the region this weekend, with both Saturday and Sunday featuring high temperatures that will struggle to reach 70 degrees at times on the mainland and mid to upper 60s on the coast.
Have a great day!
