Happy Wednesday! Today will feature more pleasant weather with more sunshine and seasonable temperatures this afternoon. But another, larger storm system we’ve been talking about this week, will be bring more heavy rainfall tomorrow.
Happy Monday! Pleasant weather continues today as high pressure slides offshore this afternoon. Some mid and high level clouds will make their presence known as the day goes on, but sunshine will filter through the clouds until at least the late afternoon hours. This will help temperatures rise into the lower and middle 60s over much of NJ, NYC and even parts of the interior. A light southeast wind may keep high temperatures in the mid and upper 50s closer to the shores, including Long Island.
Tropical moisture and just enough lift combined to support the development of torrential rains on Saturday, with localized flash flooding reported both in New Jersey and throughout the Mid Atlantic. Much of the same is forecast on Sunday, with a warm front nearing the area during the afternoon. This may be particularly true across Northeastern New Jersey, where a convergence zone will allow for moisture to “pool” along a frontal zone.
This allows for a few things to occur, but most notably, it juxtaposes lift and moisture to develop torrential rains. With plenty of anomalous moisture still available throughout the area, the recipe could be there once again for flash flooding in localized areas. Upwards of 2″ of rainfall in relatively short periods of time could cause problems, especially in flood prone areas.
Hot and humid weather will continue today, with heat index values expected to again rise into the mid to upper 90’s by the late morning and afternoon hours. The temperatures will again be hot, but the bigger story by this afternoon and evening will be the dew points, which are expected to rise into the 70’s. The combination will lead to heat index values higher than yesterday. The air will feel quite oppressive as well, especially as the afternoon draws on into the evening.
