Records: Highs: EWR: 66 (2000) NYC: 62 (2000) LGA: 62 (2021) JFK: 61 (2021) Lows: EWR: 6 (1951) NYC: 1 (1919) LGA: 9 (1951) JFK: 16 (1973) Historical: 1884 - A three week blockade of snow began at Portland, OR. A record December total of 34 inches was received. (David Ludlum) 1903: Wilbur and Orville Wright made four brief flights at Kitty Hawk, North Carolina with their first powered aircraft on this day. After having success with their 5-foot biplane kite, the brothers realized the weather conditions in Dayton were not ideal for their flying experiments. They wrote the Weather Bureau in Washington, D.C. requesting a list of suitable places on the east coast where winds were constant. Below is the response the Wright Brothers received from Joseph Dosher, who staffed the Weather Bureau office, wrote in August of 1900 regarding the suitability of Kitty Hawk. 1924 - A severe icestorm struck central Illinois. It coated the ground with nearly two inches of glaze at Springfield. The storm caused 21 million dollars damage along with much hardship. Ice was on the trees until the 4th of January, and electricity was not restored until January 10th. (David Ludlum) 1924: From the Monthly Weather Review, "a severe glaze storm occurred in west-central Illinois on December 17 and 18, the area of great destruction embracing a territory about 75 miles in width and 170 miles in length. In the affected area, trees were badly damaged, wires broken, and thousands of electric poles went down. Electric services were paralyzed, and it required weeks to restore operation and months to permanently rebuild the lines. The street railway company and the Illinois Traction System resumed complete operation 17 days after the storm. Electric light service was completely restored January 10. The ice had practically disappeared from the trees and wires by January 4, but on January 20, there was still considerable ice on the ground. The Western Union Telegraph Co. lost 8,000 poles and the Illinois Bell Telephone Co. about 23,000. The total damage to wire service in Illinois probably equaled or exceeded $5,000,000." If the loss of business, the damage to trees and possible injury to winter grains, the storm may be considered one of the most disastrous of its kind in the history of Illinois." 1929 - An icestorm in western New York State resulted in much damage and hardship. A Buffalo report stated, "one was kept awake by the breaking limbs, which snapped off with a report much louder than a rifle shot." (17th-18th) (The Weather Channel) 1987 - A storm in the southwestern U.S. brought heavy rain and heavy snow to parts of California, Nevada, Arizona, Utah and New Mexico. Charleston NV was blanketed with 12 inches of snow. Lake Havasu City AZ was drenched with 2.26 inches of rain. (Storm Data) (The National Weather Summary) 1988 - Squalls brought locally heavy snow to the southeastern shores of Lake Michigan. Totals in Michigan ranged up to 14 inches at Harvey. Totals in Ohio ranged up to 16 inches at Chardon. (The National Weather Summary) (Storm Data) 1989 - Twenty-one cities from Kentucky to Pennsylvania reported record low temperatures for the date, including Columbus OH with a reading of 12 degrees below zero. Heavy snow continued in the Colorado Rockies. Vail received 65 inches of snow between the 14th and the 18th of December. Steamboat Springs was buried under 74 inches, and reported a total of 108 inches of snow between the 10th and the 18th of the month. (The National Weather Summary) (Storm Data) 2002 - Thunderstorms preceding a strong cold front pushed into the U.S. Mississippi Valley, producing severe weather and tornadoes. Three people were killed in Missouri and Arkansas with more than 40 injuries (Associated Press). 2008 - A winter storm dumped as much as 3.6 inches of snow across Las Vegas, Nevada, prompting the closure of schools and highways. This was the largest December snowfall on record and the heaviest snowfall since January 1979 when a total of 7.5 inches fell (Associated Press).

29 / 21 warm the next 3 days Wed - Fri with perhaps some of the warmest areas touching or close to 60 on Friday, otherwise mid/upper 50s. Overnight Thu into Fri upto an inch of rain. Colder Saturday - warmer Sunday- then back down Mon - tue before warming Chirstmas eve. Overall looking warmer between Christmas and the 30th with strong nationwide ridge perhaps a day in there that approach 60 / record high?. Colder air just to the north and the warmest is to the south west. Still would watch the period 12/30-31.

The latest guidance shows a WPO-, EPO+, NAO+, PNA- pattern for late December. This pattern typically is not a "torch" in the Northeastern U.S. and eastern Canada. Using New York City as an example, some statistics: December 20-31, 1980-2024: Mean temperature: 38.0° (1991-2020 Mean: 37.4°) Distribution of Highs: 30s: 19% 40s: 63% 50s: 6% 60s: 13% Lowest: 33° Highest: 65° Distribution of Lows: 20s: 38% 30s: 50% 40s: 13% Lowest: 24° Highest: 42°

Snowfall totals from the Dec 12th event are done and up on the site along with all the events so far for the 25-26 season. I changed the ranges to 0-1/1-3/3-6/6+ to be more for fitting for the variety and location of reports. Reports are from here, cocorahs, coop and official climo sites. Thanks to everyone who sent a report to me. https://www.jdjweatherconsulting.com/sne-25-26

This is wild lol

Now I can lie about my obs and you can’t challenge me. Enjoy! Lets see a picture

Thanks to everyone who sent a report to me. I always include the climo sites, i saw the controversy with the NYC ob. It seems ISP is suspiciously low as well as all the reports in every direction are in the 6-8" range. https://www.jdjweatherconsulting.com/tri-state-25-26

This sums everything up quite well...snake-bitten era continues.

Should happen again.

I’m still waiting for any blocking to help us here…lately it’s been hurting us rather than helping. Let’s hope this time it can be our Allie.

Gonna see a lot of guidance changes in the day or two IMHO for next week…you have that pig ridge in the central CONUS but it’s flat and somewhat zonal so little disturbances are FLYING across the country in the flow….makes for decent model chaos. On top of that you have some blocking trying to form in the Atlantic which adds in more uncertainty.

At first look it seems the Euro and GFS are far apart, but they really aren't. Seems the GFS is sensing more of a cold press. That seems to be the theme this season so far, mute the warm ups

Yea, lovely-

Gotta watch 12/23-24 too for a little disturbance. Obviously there’s the Xmas day threat too but not every model agrees on timing.

Blocking keeps showing up on the modles which is great.

Off hour runs to the rescue…however it was the off hour runs that kept Sunday alive all last eeek, and they were right. So there’s that.

Needs to drop about 50-75 miles south and we got "something" per 6z

If I had a hundo for every time I heard that! But, I did see it happen... ONCE haha. I actually have it on video somewhere, probably about 1987. Golf ball flakes for about 10 minutes, about how long the old video recorders could hold a charge lol

Kind of wild in the wx model world at 0z and 6z. The 6z GFS cuts into the Chinook lifespan fairs significantly. IF the NAO is a realistic player, it is likely going to turn the pattern after 240 upside-down. It sure did last night on several runs.

All we can say is that the first 16 days of December have been one of our coldest 16 day periods relative to the means of the 2020s so far. The clipper was a nice contribution to this period feeling very wintry around the area. This was actually the coldest first half of December in 20 years. The new Newark records for December now go back to 1850. So this was ranked 26th coldest which is very respectable in our warmer 2020s climate. The current 7 station departure across the area is -7.7. With the moderation coming up next few weeks, the final number this month may finish in the -3 to -4 range. Models have been fluctuating from run to so we won’t know the exact number for a weeks.

Ya drive them yourself…let the snow come. We beggars..we need anything we can get . Fire up the Ram!

OMG…truer words were never spoken lol. And the one time it might, it was literally for about a minute to a minute and a half…maybe 10 flakes lmao…what a joke. Great recall United.

Lets keep those systems away from Christmas day! Get that Eve wave in early, and keep the second one for Christmas night! We're having our first big family GTG in a while and don't want people to cancel. Shit, I'll fill up the Power Wagon and drive them myself LOL
