there's a synoptically- and nocturnally-induced increase in the low-level jet tonight that will help a good chunk of LI and CT cash in on tropical downpours, but be careful what you wish for. these features combined w/ 2"+ PWATs will almost always produce flash flooding. could see some wet microbursts and maybe a spin-up here or there later this evening, as well.
aside from widespread heavy rainfall, it's not quite clear what will happen in the city since the transition/lull from diurnal to nocturnal forcing occurs nearby. should be some interesting radar loops this evening at the least.
