Since it's dry out there and we could use a good soaking, I'm glad to see that the models haven't backed down on the heavy rain for tomorrow night. Still looking like a nice 1 to 2 inch soaking. 

Not dry here. Sure it hasn't rained much this month but the ground is still wet and muddy and the Croton River and all of the reservoirs here are as high as they can be. It's wet right up through Dutchess County and NW CT.

Grass and trees stopped soaking up the water....the same period in September would end up with dry ground...

We have issued a Freeze Watch for Bronx, Richmond (Staten Island), Southern Nassau, and Hudson Counties 12:00 am-8:00 am EST Tuesday November 21, 2023.  The watch is in effect where temps could fall to 30-32 degrees. The growing season has not officially ended here (ends Nov 21).

Forget the freeze watch where I am. It  was 29 this morning and that is about the 4th or 5th time below freezing.

Tomorrow will be increasingly cloudy and somewhat milder. Showers could arrive late in the day or during the evening. Temperatures will generally top out in the upper 40s and lower 50s.

A strong cold front will move across the region Tuesday night into Wednesday. A storm along the front will bring a general 1.00"-2.00" rainfall with some locally higher amounts.

New York City's annual precipitation will surge past 50.00". Years with 50.00" or precipitation have increased dramatically since the City's climate became abruptly wetter in 1972.

The frequency of 50.00" or above years is as follows:

1869-1971: Once every 7.9 years
1972-2023*: Once every 2.3 years
Since 2000*: Once every 1.8 years

*Includes 2023 as a 50.00" year. 2023 currently has 49.70". No year had less than 0.30" from November 19-December 31. The record least precipitation during that timeframe was 0.67" in 1955.

Following the storm and frontal passage, a renewed shot of cold air will arrive. However, the latest guidance is warmer than it had been previously. Thanksgiving Day will be blustery and cooler. Some additional showers are possible Friday into Saturday. The remainder of November will likely be generally cooler than normal. However, no Arctic blasts appear likely.

The ENSO Region 1+2 anomaly was +2.0°C and the Region 3.4 anomaly was +1.9°C for the week centered around November 15. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.27°C and the ENSO Region 3.4 anomaly has averaged +1.70°C. El Niño conditions will likely continue to strengthen into the early winter as the current East-based event completes its evolution into a basinwide El Niño.

Currently, 2023 is in uncharted territory as far as the ENSO Region 3.4 anomaly and PDO are concerned. The October ENSO Region 3.4 anomaly was +1.59°C while the PDO was -1.71. Prior to 2023, the lowest October PDO when the ENSO Region 3.4 anomaly was +1.00°C or above was -0.36 in 1965.

Should the ENSO Region 1+2 and 3.4 anomalies remain at or above +1.00°C in December, which is likely, and should the PDO remain negative, there is a single past case (1950-2022) with similar conditions: December 1972.

The SOI was not available today.

The preliminary Arctic Oscillation (AO) was +1.003 today.

On November 18 the MJO was in Phase 8 at an amplitude of 1.507 (RMM). The November 17-adjusted amplitude was 1.535 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 80% probability that New York City will have a cooler than normal November (1991-2020 normal). November will likely finish with a mean temperature near 46.4° (1.6° below normal). That would be New York City's coldest November since November 2019.

Yup. That makes such a big difference but we've been getting enough to keep the surface moist and blocking the lower level moisture from evaporating. Meanwhile the western 40% of the state is dry to very dry.

If it stays clear, the temperatures could hit single digits in parts of the Catskill and Adirondacks.

Looks like the forecast is for 1° at Saranac Lake but the record is -10°.

Saranac Lake Area, NY
Period of record: 1903-03-01 through 2023-11-19

11/21 -10 in 1933 -3 in 1903 -2 in 2018

Below normal but nothing crazy for the good rad cooling spots

A famous cold spot in our forecast area, Saranac
Lake, has a forecast low of around 0 degrees Fahrenheit.  It`s only a
single night with this frigid cold though, as a storm system
approaching will advect in
 milder air and increasing clouds for the following periods.

Cold air drainage special.

Interesting article. I have found on calm, clear nights, the temperature difference can be surprising over very short distances. In February of 1979 Old Forge NY (not to far from Saranac Lake) hit the NY State record low of -52 degrees. Would have been interesting to know what the temperature was at  Lake Clear that night.

Looks like the low topped squall and 40+ mph gusts come through early tomorrow. Then a mostly dry day for travel with highs near 60° on Long Island. Then a seasonable and dry Thanksgiving with highs in the low 50s. So great travel weather around the holiday.
