Light rain and drizzle will continue into the night. Across northern and western Maine, an appreciable snowfall is likely. Parts of that region could see 3"-6" of snow with locally higher amounts.

Tomorrow will become milder with temperatures reaching the lower 60s in the northern Mid-Atlantic region and approaching or reaching 70° or above from southern New Jersey southward. However, much colder air will pour into the region tomorrow night. Afterward, the coldest air of the season will cover the region to end October and begin November. The chill will moderate by next weekend.

October is solidly on track to finish as a warmer than normal month. Since 1950, only a single El Niño event with a monthly ENSO R3.4 anomaly of +1.00°C or above was warmer than normal in New York City during October: 2015 (sample size: 6). If one lowers the ENSO R3.4 anomaly to +0.75°C or above, only two 2/12 (17%) of El Niño cases saw a warmer than normal October in New York City: 1963 and 2015. Both years saw warm Octobers followed by warm Novembers.  

The ENSO Region 1+2 anomaly was +2.3°C and the Region 3.4 anomaly was +1.6°C for the week centered around October 18. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.57°C and the ENSO Region 3.4 anomaly has averaged +1.57°C. El Niño conditions will likely continue to strengthen into the fall with the current East-based event transitioning to a basinwide El Niño for the upcoming winter. That transition is currently underway.

The SOI was -3.29 today.

The preliminary Arctic Oscillation (AO) was -0.943 today.

On October 26 the MJO was in Phase 7 at an amplitude of 1.239 (RMM). The October 25-adjusted amplitude was 1.256 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal October (1991-2020 normal). October will likely finish with a mean temperature near 60.4° (2.5° above normal).

Misty and foggy muck.  Visible satellite has clouds strapped in from CNJ north - but wouldn't rule out some northward advance and breaks of sun later. Warmer 60s perhaps a 70 CNJ.   Cool down / chill down 11/1-11/3 first frosts and freezes inland Tue night / Wed Am, Wednight / Thu am,  before moderating back to and above normal.  Looks like the weekend streak could break this coming weekend 11/4-5.  Coold back down by the 8th and into the following next weekend 11/8 - 11/11 - stormy longer range guidance that period to break the relatively dry stretch.

1925 - Nashville, TN, was blanketed with an inch of snow, their earliest measurable snow of record. (The Weather Channel)

1947 - The Donora, PA, smog disaster finally came to an end. For five days an inversion trapped impurities in the lower atmosphere over the Monongahela Valley killing 20 persons, and leaving more than 2000 others sick. (26th-30th) (David Ludlum) (The Weather Channel)

1987 - Severe thunderstorms in Oklahoma produced golf ball size hail and wind gusts to 74 mph near the town of Gould. Unseasonably warm weather prevailed across the central U.S. Temperatures warmed into the 80s form Texas to the Lower Missouri Valley. (Storm Data) (The National Weather Summary)

1988 - Ten cities in the Upper Midwest reported record low temperatures for the date. The morning low of 20 degrees at South Bend IND was a record for October, and lows of 18 degrees at Grand Rapids MI and 20 degrees at Fort Wayne IND equalled records for October. The low of 2 degrees at International Falls MN smashed their previous record for the date by 11 degrees. Syracuse NY received 2.9 inches of snow to establish a record for October with 5.7 inches for the month. (The National Weather Summary) (Storm Data)

1989 - Temperatures soared into the 70s in the northeastern U.S. The record high of 73 degrees at Alpena MI marked their sixth straight day of record warmth. In the western U.S., Klamath Falls OR reported a record low of 19 degrees. (The National Weather Summary)

1991: The Perfect Storm, also known as the No-Name Storm reached maximum strength on this day with a low pressure of 972 mb and sustained winds of 69 mph.

Dry stretch? My backyard stopped squishing when you walk on it on Thursday for the first time in 2 months. I don't think of that as dry.

Same here-rain every weekend has made things saturated and with vegetation going dormant it's soggier now than say a month ago...

Here are some recent numbers for the Sunday-early Monday event. Essentially this shows the EC-EPS and GEPS-GGEM-RGEM were far too far north in their predictions for qpf 06z Sunday-12z Monday, with the GFS/GEFS much-much more accurate here in the northeast USA.   Note the NYC reservoir data is from before yesterdays event. So... we're 16% above normal. 

The GFS on large scale systems should not be trashed.   Buying into the EC well in advance can be fraught with as much error as the GFS.  In this case and probably the upcoming event early Wednesday... the GFS should prevail on best axis of qpf. 

Also...so far this season, in my mind,  the GEPS-GGEM-RGEM (Canadian) has slipped to #3 behind the GFS, EC.

I don't look at any other model too closely beyond 60 hours...don't have time and its a bit of a distraction for me when I';m trying to gauge reliability.  1003A/30
