Wasn't March 2014 supposed to be snowy and somehow the storms all ended up suppressed (very unusual in a spring month)?

How did DC do in February 1989 and December 1989, Don?  Those were our two biggest busts in the 80s when 6-8" was predicted and we got virga in the former and rain in the latter.

 

February 1989 had a monthly total of 1.0” at DCA. 2/24 brought just 0.3”. December 1989 was much snowier with 9.0”. 12/8 3.6” and 12/12-13 4.5” were the biggest events.

That forecast Arctic shot for early next weeks looks like it will be colder than anything NYC has seen in the last 2 winters. So this could be the first single digits for NYC in 3 years. The Euro continues with impressive cold for a few days.

One of our  next big climate milestones will be a winter we’re it doesn’t drop below 20. That would bring us to zone 8 and introduce allot of semi tropical plants and trees (many more hardy palms) luckily we are already safe this winter with 19 at the park this morning.

Washington, DC has now gone 1,066 days since its last sub-20 temperature.

LGA was our only station not to drop below 20° during a cold season. But all the other stations came close in 01-02. I can still remember joggers wearing shorts on the LB boardwalk during that lack of a winter.

Europen with 850 temps forecast AT -24C or less could translate to zero or sub  degree readings inland Jan 11-12

Technically, it was sub 20 here this am (19.7) but I record that as 20.

Does anyone record without rounding?  If the decimal is .5, I round to the even number.  Keeps things more even ;)

 

Same here.  Dipped just below 20 this morning but it goes in the books as 20.

25 years ago it would have been in the single digits last night for the city..

If the storm had come 100 miles further north and gave us even a few inches of snow, many of us would've been 5 degrees colder at least. Atlantic City was down to 10, Dover DE was 13, BWI was 15.

well central park had no snow and even without snow with this air mass would have been in the single digits 25 years ago..

Milder air will return tomorrow ahead of the next cold front. There could be some showers. It will turn colder on Thursday ahead of a possible snowfall on Friday. At present, it appears that the storm will develop a little too far offshore and too late to deliver a significant snowfall to the region. Instead, it could be the type of storm that brings a 1"-3"/2"-4" snowfall with higher amounts in eastern New England and across eastern Long Island.

January commenced with an AO-/PNA- pattern. That typically favors somewhat cooler than normal readings in the East. For NYC, the January 1-10, 1991-2020 mean temperature for such cases was 33.5° (normal: 34.8°). This time around, the average will be warmer, but the overall tendency toward cooler weather is underway. By mid-month, New York City's temperature anomaly could be near or even somewhat below normal.

The coldest air will likely remain confined to the Pacific Northwest, Northern Plains, and western and central Canada through this week. Afterward, the cold could press farther south into at least the northern Middle Atlantic and Ohio Valley regions. Arctic air could reach the Middle Atlantic region during the second week of January. There is a chance that temperatures will fall well into the teens and perhaps even single digits in New York City early next week. The colder pattern that has discontinuously developed just after the New Year last for two or perhaps three weeks before it breaks down. Thus, it could begin to break down sometime in the January 15-20 timeframe.    

The ENSO Region 1+2 anomaly was -1.5°C and the Region 3.4 anomaly was -1.0°C for the week centered around December 29. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.33°C and the ENSO Region 3.4 anomaly has averaged -0.98°C. La Niña conditions will likely persist through meteorological winter.

The SOI was +3.40 today.

The preliminary Arctic Oscillation (AO) figure was -0.649 today.

On January 2 the MJO was in Phase 7 at an amplitude of 2.183 (RMM). The January 1-adjusted amplitude was 2.086 (RMM).
