March 7: Afternoon Winter Storm Observations

Discussion: The storm center is now to the east of New Jersey. It should slowly begin to pull away from the coast to the NE. As this happens precipitation will shut off from SW to NE. I expect far-SW areas  near the Delaware Memorial Bridge to begin wrapping up in the next hour. I expect NENJ/Monmouth County to wrap up last (between 6-8pm or so). Very intense rates of snowfall are expected until precipitation shuts off (up to 2-3 inches per hour) and more thundersnow is definitely possible.

Upper-level energy was able to influence the system colder overall and that is why the intense precipitation rates are able to overcome a 38F surface (for areas of stickage). The dynamics were and are simply incredible with this system. I will likely be adding last Friday and today’s events to the slide show I present during public talks.

Expect winds to remain gusty overnight, beyond the precipitation shut off. Coastal flooding has been held to minor levels by lower astronomical tides despite the onshore wind-driven surge today. Tidal cycles should begin lowering overnight and return to near-normal in the next few days.

In English: The jackpot of the storm system has shifted out of EPA/NWNJ and more towards the NWNJ/I-95 corridor. Most areas are all snow now. Snow will end from SW to NE between now and 8pm from SWNJ to NENJ (including Monmouth County). Expect the sky to puke hard from now until then. Hope everyone is making out alright. Be safe! JC
