It was nice not to have a big salt build up on the cars and roads this winter. Nor were there many of those big ugly snow banks that just collect dirt and car soot on the side of the roads. 

from a hobbyist/snow lover point of view the winter sucked, but practically speaking, no salt, no snow days for the kids, lower heating bills, no snow to clear etc...that part was a plus

I don’t see a cooler pattern in the spring. Weeklies keep the torch going into April. This -epo in January would give us the same results with the -pna. 
 

enjoy the weather and put this winter behind you already. 

I can’t believe the EPO is still being hyped for cold lol it’s spring lol and like you said -EPO with RNA is warm. It’s a torch right into April

Expecting that the forecast EPO- will lead to sustained cold will likely lead to more disappointment in a disappointing winter/opening to spring.

Given the impact the sustained strongly positive AO has had on the atmosphere, one will likely see a continued tendency for ridging and above normal temperatures in the East during the March 11-25 period overall despite the forecast development of a negative or strongly negative EPO. One saw such circumstances during the same period in 1990 when the EPO averaged -1.000 or below following the extreme AO+ for February. Overall, March remains on course to be much warmer than normal.

Let's hope that hold into April-nothing worse than cold/drizzle with blocking in April like last year

An extended period of generally above to much above normal temperatures continues. The warmth should persist until at least the closing 7-10 days of March. During this time, any intrusions of cold air should be brief and limited in magnitude.

Based on the historic data, no significant snowfalls (6" or more) are likely in the major Middle Atlantic cities (Baltimore, New York City, Newark, Philadelphia, and Washington, DC) through the remainder of the 2019-2020 snow season. There is a greater but still low probability for Boston to see such a snowstorm.

As a result, New York City will very likely finish winter 2019-2020 with less than 10" snow for the first time since winter 2011-2012 and for only the 10th time on record. Snowfall records go back to winter 1868-1869 (when 25.5" fell from January-March 1869).

The ENSO Region 1+2 anomaly was +1.1°C and the Region 3.4 anomaly was +0.5°C for the week centered around March 4. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.58°C and the ENSO Region 3.4 anomaly has averaged +0.45°C. Neutral ENSO conditions will likely prevail through March.

The SOI was +1.00 today.

Today, the preliminary Arctic Oscillation (AO) figure was +4.006. The previous daily record was +3.296, which was set in 1977.

There are now some emerging hints that a "final warming" seasonal event could begin to develop in the extended range. More guidance will be needed to gain confidence in such an event. Overall, most of the stratosphere is forecast to remain cold on the EPS through March 19.

On March 10, the MJO was in Phase 5 at an amplitude of 1.327 (RMM). The March 9-adjusted amplitude was 1.499.

A sizable majority (>80%) of years during which the AO has been, on average, strongly positive during the first 15 days of February were followed by a warmer than normal March. The preliminary February 1-15 AO average was +2.758. Only 1989 (+3.336) and 1990 (+2.948) had higher AO averages during this period. Recent rapid warming in ENSO Region 1+2 has also typically preceded a warmer than normal March and spring in the Middle Atlantic region. A warmer than normal March and spring remain the base case.

The ECMWF monthly and seasonal guidance initialized on March 1 shows a much warmer than normal March. It also shows a warmer to much warmer than normal spring.

February 2020 saw the ENSO Region 1+2 anomaly increase by more than 0.50°C. Such a development has typically occurred before a warmer than normal summer. In all such cases, a warmer than normal spring was followed by a warmer than normal summer. Therefore, a warmer than normal summer is currently more likely than not. Should Spring wind up warmer than normal, a warm or even hot summer will be very likely.

Based on sensitivity analysis applied to the latest guidance, there is an implied 90% probability that New York City will have a warmer than normal March.

The next 8 days are averaging 47.5degs., or about 6 or 7 degs. AN.

Month to date is  +9.0[48.4].        Should be  +7.0[48.0] by the 20th.

The next 17 days are averaging (06Z, GFS) 46.5degs.[40/53], or about 2degs. AN.     A colder run, but snow less anyway.

47* here at 7am.

That's why +AO, crazy progressive patterns are the worst. They cause warm cutters but also late developing/suppressed storms like this and the one that recently hit NC/VA and out to sea. When storms do form to our south the fast jet shoves them out to sea. Phasing happens too late or not at all. It all just comes together to shaft our area time after time. Needless to say some small tweaks could've caused a monster for our area. Instead we have some light rain and some kinda mangled snowflakes when you look at the streetlight. 

shades of 2001-02 (and 1972-73 too)

My favorite part of that day? Being at work, seeing the snow falling and it looking like January and having WFAN on the radio and Mike and the Mad Dog are just laughing while watching the game on tv and killing Steinbrenner for not canceling the game.

I feel pretty confident that won't be an issue this year.

that was one of the most amazing games to watch, I loved every second of it!

Great winters in that stretch but some of those summers were absolutely awful. Although Dewsaster 2018 can compete with any of those.

As for Floyd, that was the second weather event I remember from growing up after the 1998 Labor Day derecho. The small lake next to my elementary school tripled in size and merged with a nearby creek to force the only rain-induced early dismissal of my school career.

I loved the contrast between the winters and summers, the high dewpoint summers we are having now are definitely the worst, I'd much rather have the high heat low humidity summers that actually feel refreshing because the air is so dry.  I think we're headed towards more of those summers, especially with the 11 year cycle peaking again next year.

Epo is going to be crashing.  Where the hell was this during the winter ?

It’s still going to be a torch here though. Severe -PNA. The result would have been the same even in winter. Huge SE ridge pattern, -EPO doesn’t automatically mean cold East as we are about to see.....

A system will bring some rain to the region tonight into tomorrow. Afterward readings will surge into the 60s before modestly cooler air overspreads the region.

The next 8 days are averaging 46.5degs., or about 4.5degs. AN.

Month to date is  +8.7[48.2].        Should be about  +7.0[47.5] by the 21st.

The next 17 days are averaging (06Z, GFS) 50*[42/58], or about 5degs. AN.

EURO Weeklies are 6 straight weeks AN.         CANSIPS has 12 straight months of intensifying heat everywhere.     Well, maybe the Heat will get the coronavirus before either it or the heat gets us.

48* here at 7am with FOG---<0.1mile, rainy.       49* by 10am, same FOG, no rain.        55* by Noon, fog almost gone.       60* by 2pm with sun/clouds.     65* at 3pm, sun, breezy.       68* at 3:30pm.        71* by 5pm.       60* by 9pm.
