Yep, even in this climate we’re almost guaranteed another couple of freezes outside the city. 

That's going to be a bigger problem down the line. Very early blooming only to get damaged by unusual late freezes.

good - this early blooming is the earliest I have seen and the birds are chirping outside at 4 AM - maybe the cold will shut them up too till dawn.......

Looks like multiple freezes and even hard freezes likely just outside the city and immediate coast coming week.

Should put a damper on any early blooms and leafouts. 

EPS showed this a week ago, yet GEFS was posted with warmth instead.

It’ll hold the bugs off for a while which is always good.

LOL at people acting like we are getting a snowstorm this week. Normal march temps incoming. Our last freeze usually is early April 

areas north of I-80 have a good chance of some the next few weeks....

It’s the areas that sustain a hard freeze in the mid 20s that are most susceptible to plant damage after an early bloom.


https://hortnews.extension.iastate.edu/faq/hard-freeze-early-spring-damaged-newly-emerged-growth-several-trees-and-shrubs-will-plants

Question: 

A hard freeze in early spring damaged the newly emerged growth on several trees and shrubs. Will the plants recover?

Answer: 

Newly emerged tree and shrub foliage is susceptible to damage from below freezing temperatures. The new growth on many trees and shrubs can tolerate temperatures in the low 30s and upper 20s. Freeze damage is most likely when temperatures drop into the middle 20s or below. Symptoms of freeze damage include shriveling and browning or blackening of damaged tissue. Damaged growth usually becomes limp. Eventually, damaged or destroyed leaves drop from the tree or shrub. 

Fortunately, trees and shrubs have the ability to leaf out again if the initial growth is damaged or destroyed. Damaged trees and shrubs have only suffered a temporary setback. Healthy, well established trees and shrubs will produce additional growth within a few weeks. Good care during the remainder of the year, such as watering during dry periods, should aid the recovery of trees and shrubs planted within the past two or three years.

Cooler air will push into the region. One shot will begin to arrive tonight. Another somewhat stronger shot will arrive Wednesday or Wednesday night. The low temperature could approach or reach freezing on Thursday morning or Friday morning in New York City.

Milder air will begin to return during the weekend. The closing days of March could turn warm.

No significant snowfall appears likely in the northern Middle Atlantic region through at least March 20th. The probability of an unprecedented second consecutive winter with less than 10" seasonal snowfall in New York City's Central Park has continued to increase. It is now very likely that New York City will finish the 2023-2024 snow season with less than 10" of seasonal snowfall. Records go back to 1869.

The ENSO Region 1+2 anomaly was +1.0°C and the Region 3.4 anomaly was +1.4°C for the week centered around March 6. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.98°C and the ENSO Region 3.4 anomaly has averaged +1.53°C. A basinwide El Niño event is ongoing. The ongoing El Niño event will continue to fade during March. Neutral conditions could develop during the spring.

The SOI was -3.88 on March 16.

The preliminary Arctic Oscillation (AO) was -1.234 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 99% probability that New York City will have a warmer than normal March (1991-2020 normal). March will likely finish with a mean temperature near 47.9° (5.2° above normal).

Don - I like that you are being careful with not ruling out any significant snowfall past March 20th .......

Thurs night/Fri AM a freeze looks likely even within NYC. Perhaps a hard freeze at that. We'll see how these cherry blossoms and magnolia blooms fare by next weekend.

That includes interior sections e.g., NW NJ. I highly doubt that Philadelphia, Newark, or New York City will see much if any additional snowfall.

If you mean High Point State Park in Sussex County, NJ may get some more snow then I agree. The entire NYC metro area is done though

Down to 40 and partly cloudy.  Step down in temps today to upper40 / low 50s.  Colder 3/19 - 3/23.  Coldest looks to be Wed - Thu mid/upper 20s inland and near freexing city areas and coastal areas.  Warmer and wetter by the 24 and into next week.  In between clouds and rain more 60s perhaps 70s.

Historical:

1925 - The great Tri-State Tornado occurred, the most deadly tornado in U.S. history. The tornado claimed 695 lives (including 234 at Murphysboro IL and 148 at West Frankfort IL), and caused seventeen million dollars property damage. It cut a swath of destruction 219 miles long and as much as a mile wide from east central Missouri to southern Indiana between 1 PM and 4 PM. The tornado leveled a school in West Frankfort IL, and picked up sixteen students setting them down unharmed 150 yards away. Seven other tornadoes claimed an additional 97 lives that day. (David Ludlum)

1971 - High winds accompanied a low pressure system from the Rocky Mountains to the Great Lakes. Winds gusted to 100 mph at Hastings NE, and reached 115 mph at Hays KS. High winds caused two million dollars damage in Kansas. Fire burned 50,000 forest acres in eastern Oklahoma. (17th-19th) (The Weather Channel)

1987 - A storm in the central U.S. produced up to 10 inches of snow in western Nebraska, and up to six inches of rain in eastern sections of the state. The heavy rains pushed the Elkhorn River out of its banks, submerging the streets of Inman under three feet of water. (The National Weather Summary) (Storm Data)

1988 - Light rain and snow prevailed east of the Mississippi River. Fair weather prevailed west of the Mississippi. (The National Weather Summary)

1989 - A storm in the western U.S. produced heavy rain in California, with heavy snow in the Sierra Nevada Range. Venado CA was drenched with 5.40 inches of rain in 24 hours. A dozen cities in the eastern U.S. reported new record high temperatures for the date, including Baltimore MD with a reading of 82 degrees. (The National Weather Summary) (Storm Data)

1990 - Heavy rain caused extensive flooding of rivers and streams in Georgia, with total damage running well into the millions. Flooding also claimed six lives. Nearly seven inches of rain caused 2.5 million dollars damage around Columbus, and up to nine inches of rain was reported over the northern Kinchafoonee Basin in Georgia. (Storm Data)
