Good morning to you all, South Jersey, and T.G.I.F! Well, we would all be saying that a bit more if we weren't keeping a very close eye on Tropical Storm Andrea. As of this post, her current position is near Charleston, South Carolina and moving to the northeast at 15mph. While her center is well to our south, we're already experiencing the outer bands of moderate to at times heavy rainfall. This will be the running theme through the rest of the day today and into the evening, with that time frame holding the best chance at seeing some rather heavy rainfall. Beyond the rain, temperatures won't warm up too much with low to mid 70s on the mainland and 70 on the coast with a breezy southeast wind at 15 to 25mph. The main concern won't be with wind or coastal flooding per se, but the sheer amount of rainfall that is expected. With forecasted amounts of 2 to 3 inches of rain for most of us (With locally higher amounts near 4 inches), flash flooding is the bigger concern. A flash flood watch is in effect until tomorrow morning as a result. Rainfall will begin to taper off later tonight and through the overnight hours, but not before we see a few more moderate to heavy rain bouts. Lows won't drop too much due to the persistent cloud cover. Temperatures only reach the upper 60s tonight with a southeast wind at 10 to 20mph.
Thankfully, Andrea will be out of here as quickly as she arrives. The weekend, in general, is dry. However, she will leave a tropical air mass in her place, giving us some residual instability in the atmosphere as a result. Some scattered showers and thunderstorms are possible through the afternoon, and it will also be rather muggy through the day tomorrow and Sunday. Highs for the first half of the weekend reach the upper 70s on the mainland and low 70s towards the boardwalks. Sunday holds the better chance at being drier, but it will be just as muggy, warmer, and still hold the chance for a scattered shower or storm. Highs on that day will climb to the 80 degree mark. The mugginess doesn't depart until a cold front arrives on Monday and slowly creeps through the region. Scattered showers and thunderstorms are possible Monday and Tuesday with highs in the low 80s. Once that frontal boundary departs, cooler and drier air arrives for Wednesday and Thursday. Highs for both days reach the upper 70s under partly to mostly sunny skies.
Drive safely out there, and have a great weekend!
