EURO is 8" of Snow for the next 10 days. GEFS is 70% of at least 14" by Feb. 2. Link to comment Share on other sites More sharing options...
donsutherland1 Posted January 17, 2019 Share Posted January 17, 2019 2 hours ago, LibertyBell said: Don what do you think was the reason we had much colder winters back then but much less snow? Januaries back in the 80s almost universally had monthly average temps in the mid to upper 20s and the southern track was much more frequent with several cases of DC getting more snow than what they've gotten in the last couple of decades (outside of the really big winters like 1995-96, 2002-03 and 2009-10.) While synoptic patterns, along with SSTAs, likely shaped the storm tracks, the larger-scale observed ongoing warming has likely resulted in warmer January cases. Given synoptic patterns have been warmer than they were back in the 1980s. The following are mean temperatures for New York City (Central Park): January 1980-89: AO-: 29.9°; AO+: 31.8° January 2010-18: AO-: 33.1°; AO+ 34.5° A similar outcome with some differences in the extent of the warming can be seen throughout the Northeast and Middle Atlantic regions. I would post relevant charts from the NCDC site, but the site is currently down due to the ongoing partial federal government shutdown. Link to comment Share on other sites More sharing options...
bluewave Posted January 17, 2019 Share Posted January 17, 2019 We are finally going to be able to beat the November low temperature in NYC by Monday morning. Very unusual for a November monthly minimum to remain as the coldest of the season through January 19th. But it’s the 2010’s so we have become accustomed to these new types of weather oddities.

This is SO interesting, because although the temperatures have warmed by 3-4 degrees (fairly significant!) we have also seen more snow than we did back then. And we didn't just warm, we crossed a significant threshold, where the monthly average temperatures were below freezing regardless of the AO back then to above freezing regardless of the AO now in our statistically coldest month!

I think since December 1, Central Park's met winter low has only been 20 degrees? How many met winters have there been when we didn't get a low below 20 or one in which it occurred this late?

The trend over the last 24 hours of modeling has been to slow the departure of the storm a bit, but it still seems like the stratiform shield should be eroding by 0z Monday. Totality begins just before midnight, by which time the GFS cloudcover outlook is pretty favorable. The nice thing about a lunar eclipse is that even with broken overcast, it would be almost impossible not to get a clear patch around the moon at some point over the course of an hour. A solar eclipse is totally cooked if you get one wayward Cu passing through. Link to comment Share on other sites More sharing options...

donsutherland1 Posted January 17, 2019 Share Posted January 17, 2019 After a just over two-month wait, Central Park will likely see some measurable snow from a weak system tonight into tomorrow morning. A light accumulation of snow (generally a coating to an inch of snow with locally higher amounts of up to 2") will accumulate in the region. Boston, which has received a record low 0.2" snow to date (the old record was 0.7" in 1927-28), could pick up about an inch of snow. The SOI was -7.30 today. It has been negative for 15 out of the last 17 days. The Arctic Oscillation (AO) was -0.133. That is the 12th consecutive day the AO has been negative. The preliminary average for meteorological winter is -0.078. On January 16, the MJO was in Phase 3 at an amplitude of 1.089(RMM). That amplitude had risen above the January 15-adjusted figure of 0.958. This is only the second case on record where the MJO re-emerged into Phase 3 with an amplitude of 1.000 from its having gone into Phase 8 at a low amplitude. In coming days, the MJO could advance fairly quickly into and through Phase 4 and into Phases 5 and 6. As the MJO moves through Phases 5 and 6, the AO could go positive for a time (as has been indicated on the guidance in recent days). However, with the MJO's likely pushing back toward or into the colder phases near the end of the month, the AO will very likely return to negative values. Strong to perhaps severe blocking could develop in late January. The persistence of such blocking could set the stage for a snowy to perhaps very snowy February in the Middle Atlantic and New England areas. A major storm could impact the region during the January 19-21 period. A light to moderate snowfall is likely along the immediate coast. There is a growing risk of a significant period of sleet and freezing rain in parts of the coastal plain and just inland. Cities such as Albany, Bangor, Binghamton, Burlington, Caribou, Concord, Portland, Rochester, Rutland, and Syracuse remain in line to receive a substantial snowfall. Those areas could see a widespread 12"-18" snow with locally higher amounts. New York City could pick up 2"-4". However, any delay in the changeover could result in an accumulation of several additional inches of snow. A blast of bitter cold air will follow the storm. The temperature could fall into the single digits in New York City for the first time since January 7, 2018. Overall, the probability of a colder than normal average monthly temperature in the New York City area has increased further. Link to comment Share on other sites More sharing options...
bluewave Posted January 18, 2019 Share Posted January 18, 2019 EPS weeklies are going for the classic El Niño progression to colder well into February. This matches up with the MJO weakening for the first time since October in about a week. https://mobile.twitter.com/RyanMaue/status/1086035577428938752?ref_src=twsrc^google|twcamp^serp|twgr^tweet Link to comment Share on other sites More sharing options...
