Hail and Tornadoes Threaten the Region, Along with Flash Flooding and 60 MPH Winds – NBC New York (47)

You better include the umbrella in your plans for Memorial Day weekend.

Showers and thunderstorms are in the forecast for New York City beginning Thursday and extending through Sunday, according to the National Weather Service.

A storm system and jet stream, which caused torrential rain and tornadoes in the south-central United States, is expected to change course and move northeast toward the city, according to the National Weather Service.

A general rainfall of 0.25 to 1 inch is forecast with locally higher amounts distributed primarily during the first third of the three-day weekend

But there’s good news: It’s still unlikely to rain all the time, meteorologists predict. Memorial Day is expected to be sunny and summery.

“Mostly sunny, with a high in the 80s,” reads the National Weather Service forecast for Memorial Day.

So this weekend’s rain will likely usher in a glorious unofficial start to summer.

High winds, frequent lightning and flash flooding are considered likely for the region on Friday (only lightning had that distinction in the previous forecast update), while the National Weather Service’s Storm Prediction Center added the possibility of isolated tornadoes and hail. Both tornadoes and hail had previously been considered unlikely.

Damaging winds around 60 mph with higher gusts and isolated flash flooding remain the biggest threats at this time.

New York City and the immediate surrounding areas are in the potential severe weather hazard zone, with potentially severe storms more likely west of the five boroughs, through eastern Pennsylvania and western New Jersey.

The timing of the storms is quite uncertain at this time, but they could begin to enter western New Jersey by late afternoon, as early as 5 p.m., before moving east into the City of New Jersey area. New York later at night. They can weaken while doing so. Either way, people looking to get out of town early for the holiday weekend could see trouble.

Storms associated with the front could impact travel at airports like Chicago and Atlanta before they move over the I-95 corridor on Friday. Showers and thunderstorms will continue into Saturday, but conditions improve Sunday and Monday, with highs expected to reach the 80s Sunday and exceed that mark Monday afternoon under light clouds.

However, embarrassment will be a factor. The warm stretch picks up speed and continues through at least next Friday, when another series of thunderstorms associated with a cold front will bring temperatures back to average for this time of year.

HERE IS THE FULL NATIONAL WEATHER SERVICE FORECAST FOR THE BIG APPLE:

THURSDAY NIGHT

NEW JERSEY

New Jersey can expect a stormy start to Memorial Day weekend with possible severe storms on Friday packing gusty winds and causing flash flooding before more rain on Saturday, forecasters say.

The outlook for the rest of the holiday weekend looks much better with dry, sunny conditions and highs in the 80s on both Sunday and Memorial Day Monday in inland sections of the state, but highs in the 70s throughout. of the coast.

While there are glimpses of sunshine Thursday morning, National Weather Service forecasters are forecasting a “somewhat wet and dreary day” with highs reaching 70 degrees. There is a chance of drizzle anytime between 3 and 8 pm.

The weather service has issued a hazardous weather outlook for 14 counties for Friday, saying “several instances of flooding are possible, especially in poorly drained and urban areas and near particularly vulnerable small creeks and creeks.”

The outlook added that scattered severe thunderstorms are possible on Friday.

Counties not included in the hazardous weather outlook are Bergen, Essex, Hudson, Monmouth, Ocean, Passaic and Union.

Ahead of Friday’s thunderstorms, chances of drizzles and scattered showers continue through Thursday night. Forecasters also mention the possibility of patchy fog, especially north and west of Interstate 95, as nighttime temperatures dip into the 60s.

On Friday, conditions should remain dry into the afternoon across much of the state and possibly into the afternoon along the Jersey Shore before rain arrives.

Even though the weather service forecast says heavy rain and flash flooding is becoming more likely in the mid-Atlantic region, it’s not yet sure where it will happen, again emphasizing that there’s too much uncertainty.

Locally damaging wind gusts are possible, but widespread severe winds are not expected on Friday.

A muggy Friday with high humidity and high temperatures in the 70s and 80s is likely.

The forecast for Saturday calls for “unstable” conditions with areas north of Interstate 78 having the best chance for thunderstorms. Periods of rain are still possible across the state, but the weather service said the day won’t be a complete washout.

Highs on a mostly cloudy day will be in the upper 70s to near 80s.
