NYC Weekend Weather: TS Matthew – Sep 29, 2016

We are in an active weather pattern for the entirety of the weekend, with chances for rain nearly every day. This rain is welcome and much needed, as drought persists across much of the area. Friday looks to deliver the heaviest, most persistent rain. We’re also closely monitoring the progress of Tropical Storm Matthew. While Matthew is still only in the Caribbean, it appears increasingly likely it will impact the East Coast next weekend.

Today – high pressure anchored over southern Quebec/southeastern Canada will serve to block the progress of an upper-level low that’s been drenching areas of the Mid-Atlantic. The influence of the high should keep most of the region relatively dry today, with the exception of further west in New Jersey. However, the high pressure to the east and frontal boundary siting just south of us will induce an onshore northeasterly wind, bringing cooler than normal temperatures only in the mid-60s.

Friday – rain chances ramp up considerably Friday as the front depicted to the south edges slightly northwards. This looks to bring a batch of moderate to heavy rain onshore primarily in the afternoon and evening hours. Temperatures will be even cooler than today in the low-60s with overcast skies and that persistent northeast wind.

Saturday – temperatures warm up a little into the upper-60s, but rain chances continue throughout the day along with overcast conditions.

Sunday – rain chances begin to diminish as temperatures continue to warm to around 70ºF. Even if rain doesn’t fall, it’ll still be a cloudy day.

Tropical Storm Matthew – Potential East Coast Impact?

Tropical Storm Matthew formed just east of the Lesser Antilles a couple days ago as a vigorous tropical storm and has been steadily progressing west and growing in intensity. Matthew is already a 65mph storm. It is being impacted by moderate southwesterly wind shear that will impede significant strengthening the next couple days. However, this shear is expected to ease as it moves over the warmest waters of the Caribbean. That should allow for more rapid intensification.

Of course, Matthew is far from being a threat to us now, but for days, it’s been clear from various forecast models that this storm will eventually turn north. The pivotal question for whether Matthew becomes a direct threat to us is when this turn north occurs. It’s not looking particularly good for us now, as the forecast package from the National Hurricane Center continues to suggest Matthew will eventually move up the East Coast next week.
