donsutherland1 Posted November 2, 2019 Share Posted November 2, 2019 Under partly sunny skies, temperatures topped out into the lower 50s this afternoon. Increasingly, the New York Botanical Garden is taking on an appearance of autumn. The trees are now changing fairly quickly. 4 2 Link to comment Share on other sites More sharing options...

donsutherland1 Posted November 3, 2019 Share Posted November 3, 2019 The temperature fell to 40° in Central Park this morning. That was New York City' coldest temperature since April 11 when the temperature also reached 40°. Outside the City, widespread frost was reported. Numerous locations saw the temperature fall near or below freezing. Minimum temperatures included: Allentown: 31°; Binghamton: 33°; Boston: 39°; Bridgeport: 34°; Danbury: 28°; Harrisburg: 33°; Hartford: 32°; Islip: 33°; New Haven: 33°; Newark: 36°; Philadelphia: 36°; Poughkeepsie: 28°; Providence: 31°; Scranton: 32°; Westhampton: 25°; and, White Plains: 32°. This initial push of cooler air will likely yield to milder conditions early next week. However, an even colder air mass could arrive later next week. This air mass could be sufficiently cold to bring New York City its first freeze of the season. Some of the guidance suggests the potential for the season's first snow in parts of the northern Mid-Atlantic and southern New England areas Thursday night or Friday. The area to the north and west of New York City and Newark, from northeastern Pennsylvania eastward into New England has perhaps the greatest chance of seeing some accumulations. For New York City, 7/51 (14%) of the EPS ensembles show 1" or more snow. The following are percentages of EPS ensembles showing 1" or more snow at select locations: Allentown: 20%; Binghamton: 51%; Bridgeport: 20%; Harrisburg: 12%; Newark: 14%; Poughkeepsie: 31%; Scranton: 51%; and, White Plains: 14%. After mid-month, a prolonged period of above normal temperatures with some possibly much above normal temperatures could develop. Nevertheless, there remains uncertainty about the second half of the month. The possibility of a persistence of cold air from the first half of the month will need to be watched closely. The more likely scenario involves the large area of much above normal height anomalies covering the Gulf of Alaska shifting toward the Bering Strait and then into eastern Siberia over the next two weeks. The disappearance of the negative EPO will then set the stage for a milder regime to develop and establish itself over much of the CONUS. The ENSO Region 1+2 anomaly was -1.3°C and the Region 3.4 anomaly was +0.6°C for the week centered around October 23. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.82°C and the ENSO Region 3.4 anomaly has averaged +0.43°C. A neutral ENSO is currently the base case for Winter 2019-20. Since 1981, approximately one out of every seven December cases involved a neutral ENSO. In general, a neutral ENSO in which Region 1+2 had a cold anomaly and Region 3.4 had a warm anomaly (as has been the case in the 6 week moving average) saw a warmer than normal December. Such neutral ENSO cases accounted for about 27% of all neutral ENSO December cases during the 1981-2018 period. This data does not consider blocking, as it is too soon to be confident about that factor in December. However, the greatest warmth coincided with a negative PDO while the coldest outcome coincided with a strongly positive PDO (+1.00 or above for December). Therefore, the first part of winter could start off milder than normal in the Middle Atlantic and southern New England regions. The SOI was -2.99 today. Today, the preliminary Arctic Oscillation (AO) figure was +0.468. Since 1950, there have been five prior cases when the AO averaged -0.500 or below in both July and August: 1950, 1958, 1960, 1968, and 2015. The average temperature for September through November in New York City was 58.9° (59.6° adjusted). All cases featured a warmer than normal fall. There remains a potential for autumn 2019 to rank among the 30 warmest cases on record. For New York City, that would translate into a September-November mean temperature of at least 58.8°. On November 1, the MJO was in Phase 5 at an amplitude of 1.837 (RMM). The October 31-adjusted amplitude was 1.376. Since 1974, there were 3 cases that saw the MJO in Phase 2 at an amplitude of 1.500 or above for at least 3 days during the October 15-25 period, as occurred this year: 1990, 2011, and 2015. All three cases featured a warmer than normal November in New York City and readings that were 3° or more above normal during the second half of November. The MJO's move into Phase 5 at a high amplitude could reinforce this earlier MJO signal should it remain in that phase at high amplitude. For that reason, the base case remains a warmer than normal November, but any warm anomaly will likely be much smaller than the October one.

I wonder if the low solar is having an impact on Temps this fall and will it carry over to winter? I'm hearing this is a lower minimum than 2008 and the lowest minimum since they've been keeping records The solar minimum definitely helps, and should continue to help for the next few winters as well. 1 Link to comment Share on other sites More sharing options...

bluewave Posted November 3, 2019 Share Posted November 3, 2019 This is following our warm October to cold November pattern that has been so persistent since 2013. Even with all the record warmth in the East during October, the CONUS had its 6th coldest October since 1949. Several stations out West had their coldest October on record. The cold and -EPO blocking is finally shifting east for November like we have seen in recent years. 1 Link to comment Share on other sites More sharing options...

If we get some kind of major or even moderate snowstorm this month lets see if your theory holds up that early season snow may be bad for us because when the pattern flips to mild it doesn't have enough time to flip back to cold and snowy again until half the season is over. 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted November 3, 2019 Share Posted November 3, 2019 At 11 am EST, temperatures were running near or even above the MOS forecast for 18z. Bridgeport: 52°; 18z Forecast: 53°; Forecast high: 55° Islip: 52°; 18z Forecast: 52°; Forecast high: 54° New York City: 50°; 18z Forecast: 51°; Forecast high: 52° Newark: 52°; 18z Forecast: 52°; Forecast high: 54° As a result, readings in parts of the region could top out somewhat above what the MOS guidance had suggested. 1 Link to comment Share on other sites More sharing options...

There’s no question it has some sort of bad correlation but I don’t believe the snow event itself is the reason. It’s the pattern which leads to the snow event. Chances are if you see a snow event before 11/20-11/25 in this area you’re under some sort of anomalously cold pattern. There’s been plenty of evidence that getting too cold too early can cause some sort of atmospheric reshuffle between the mid latitudes and polar regions that impacts the winter. 89-90 is one example and there’s quiet a few others. 2 Link to comment Share on other sites More sharing options...

Many folks share this view. Some concerns are increasing the odds that the holiday period will be very warm, such as recent years, also that the cold air mass is wasted because snow climo itself is still too early and hostile. However, some areas of the country I have seen in the past do start early, with cold and snow, and remain so during the heart of winter. I hope this is not a head fake. I believe there are plenty of reasons to expect cold and snow in the NE this winter. Link to comment Share on other sites More sharing options...
