Currently looks like the best chance for NYC accumulation should be the colder surfaces like the grass in Central Park. Link to comment Share on other sites More sharing options...

donsutherland1 Posted December 10, 2019 Share Posted December 10, 2019 Tomorrow will be very mild in the Middle Atlantic and southern New England region. Temperatures should top out in the upper 50s in southern New England and lower 60s in much of the Middle Atlantic region. This unseasonable warmth will be short-lived. As the front slowly moves eastward, a wave could develop along the front bringing parts of the region a light snowfall late Tuesday into Wednesday morning. New York City, Newark, and Philadelphia could be in line for perhaps an inch or two of slushy snow, especially on grassy surfaces. Outside the cities, a general 2"-4" with locally higher amounts appears possible. Lesser amounts remain possible should the arrival of the cold air be somewhat delayed. The ENSO Region 1+2 anomaly was +0.1°C and the Region 3.4 anomaly was +0.3°C for the week centered around December 4. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.23°C and the ENSO Region 3.4 anomaly has averaged +0.67°C. These recent conditions are consistent with a weak El Niño. Nevertheless, a neutral ENSO remains the base case for Winter 2019-20 and the recent cooling in Region 3.4 suggests that the base case remains viable. The SOI was -4.72 today. Today, the preliminary Arctic Oscillation (AO) figure was +0.922. In the long-range, there is disagreement among the guidance. The GEFS is colder than the EPS. The latest week 2 and 3 forecasts for the CFSv2 have moved dramatically away from the severe cold that prior runs had shown. The progression of the MJO over the next 10 days and the evolution of the AO could provide insight. No significant stratospheric warming event appears likely through December 18. Wave 2 activity is forecast to remain suppressed and the stratosphere is forecast to remain cold past mid-month on the EPS. According to NCEP, the correlation of 16-day 10 mb GFS temperature forecasts is near 0.25 (much worse than flipping a coin). 5 mb forecasts have an even lower correlation. When it comes to New York City's 4" or greater snowstorms the PNA is more important than the AO during the first half of December. Since 1950, December 1-15 has seen 10 storms bring 4.0" or more snow to New York City. 50% occurred with an AO- or AO+. However, 80% occurred when the PNA was positive. All 6" or greater snowstorms during this timeframe occurred when the PNA was positive. The December 1-3 storm occurred with a negative PNA and Central Park received 1.6" snow. During the second half of December, larger snowstorms have occurred with a negative PNA. 1 Link to comment Share on other sites More sharing options...

We touched on this last week ( new research ) about the MJO cycling through the colder phases quicker, with more time spent in the warmer phases courtesy of the West Pac warm pool. Do you have any idea when, or if the Pac Jet will slow down, or is that outcome unlikely? I know you saw the too the record + IOD is weakening. On a side note, actually seems up next might be the development of a West based - NAO and after the weekend rainstorm a potential winter storm threat.

IMO this is actually helping us score some light snowfalls (last Monday, tomorrow), with a POTENTIAL for a heavy event next week. Hard not to score some snow events in winter when precipitation is in abundance, even if the air is more Pacific in nature. Link to comment Share on other sites More sharing options...

Root for the storm this weekend to become the 50/50 for it. That could allow high pressure to stay anchored over the Northeast. But I am weary of day 8 colder solutions. We have seen these correct warmer closer in recently. 1 2 Link to comment Share on other sites More sharing options...
SnoSki14 Posted December 10, 2019 Share Posted December 10, 2019 MJO avoiding the warmer phases thus far, some have it looping around toward the better phases from the circle last week of December. This is noticeably different than last year which had it going through 4-6 and lingering there for weeks. This could be why a -AO/neutral NAO are showing up 2nd half of December. Personally I'm a fan of this progression and it's why January could be a surprisingly good month. Link to comment Share on other sites More sharing options...

Hard not to score some snow events in winter when precipitation is in abundance, even if the air is more Pacific in nature. This is reminding me of a December 1986 pattern with a negative EPO and plus AO, NAO regime with frequent rainstorms that month. Lived in Central Mass that time and highly disappointed. However, Jan 87 had the switch flipped to snow and we had a record 70 inches for that month alone in Worcester, MA. It was snowstorm after snowstorm. Not saying this will happen in Jan 20, but with a very vigorous and moisture generous pattern, I think we will all score big at least once. 2 Link to comment Share on other sites More sharing options...
