I seem to remember hearing that at the time A first for such a strong El Niño. But we did it in 1977 with a weak El Niño. Link to comment Share on other sites More sharing options...
Mark McIntyre Posted January 31, 2019 Share Posted January 31, 2019 According to Staten Island's Mesonet site at CSI, 2-m temperature bottomed out at 1.6° in the 7AM hour. It has since warmed up to 6°F. Link to comment Share on other sites More sharing options...

Can you do a little comparison of what the surrounding airports did on VD 2019 vs what happened this morning? I dont think JFK or LGA went below 0 with that outbreak (I think EWR did), so this one may have matched that one for our local airports. Link to comment Share on other sites More sharing options...

NorthShoreWx Posted January 31, 2019 Share Posted January 31, 2019 Low here was +3. Could have been a little colder but we're still sucking heat out of the Sound. Our below zero days in recent years have been in mid and late February. Yesterdays squall began with a few flakes at 4:28 and peaked in white out conditions from 4:44 - 4:47. it calmed down pretty quickly after that.

donsutherland1 Posted February 1, 2019 Share Posted February 1, 2019 This morning, the temperature fell to -31° in Rockford, Illinois. That set a new all-time record low temperature for that location. The prior record was -27°, which was set on January 10, 1982. Aided by today's 2° minimum temperature, New York City finished January with a monthly mean temperature of 32.5°. That is 0.1° below normal. The SOI was +0.01 today. While the MJO moves through Phase 6, the SOI could continue to retain positive values, as is currently the case. Afterward, it will likely return to negative values. The Arctic Oscillation (AO) was -2.286. That was the lowest figure since November 27, 2018 when the AO was -3.072. The preliminary average for meteorological winter is -0.263. On January 30, the MJO was in Phase 6 with an amplitude of 1.459 (RMM). That amplitude had fallen from the January 29-adjusted figure of 1.577. The MJO will continue to advance through Phase 6 and then move into Phase 7 within day or two. Upon reaching Phase 7, its amplitude could decline toward low amplitude values. It remains uncertain whether the MJO will reach Phase 8 before it either reaches low amplitude values or possibly reverses to Phase 6. The risks of a turn toward Phase 6 or a drop to low amplitude prior to any move to Phase 8 have continued to increase. Both Phase 6 and a Phase 7 at low amplitude favor a positive AO. As the dynamic models have shifted toward an increased likelihood of either outcome, the ensemble guidance has shifted toward at least a period where the AO goes positive. Such a turn would fit with the upcoming warmup that is forecast. Strong blocking could have blunted its magnitude, but now the guidance has shifted toward a less blocky outlook for perhaps a week. The operational ECMWF, GFS, and EPS forecast high temperatures in the 50s to perhaps 60° during the February 3-6 period in the northern Middle Atlantic and southern New England areas. Farther south, parts of the Middle Atlantic region could experience a high temperatures in the 60s. Colder air should follow by the end of that week. There is a possibility that a predominantly colder than normal regime could then lock in for at least a 2-3 week period, especially as the EPO is expected to go negative and blocking could redevelop.

Like when you thought the SOI would drop to -10 a few days ago, and severe blocking would develop. Anyway.....I am optimistic that your optimism will finally pay off post Feb 10.

The models had been much more aggressive with the forecast WWB. It’s now clear that on account of marginal El Niño conditions, such guidance needs to be taken with a healthy dose of skepticism.

Too many people don't understand that these medium/long-range pattern forecasts are largely probabilistic, as deterministic forecasts are useless beyond about 7-8 days, due to the chaotic nature of weather. So, there will always be a decent level of uncertainty in pattern forecasts and Don conveys that well, IMO. Link to comment Share on other sites More sharing options...
