Doesn't take much to fill up the reservoirs.  Sometimes one good event.  Supposedly the real key are winter snows (Summer snows not as much).

Reservoir levels are meaningless to my well and dead garden that didn't produce the food I planned for ;)

I'm in reservoir land here and I was 25" below average last winter. I was also about 8" shy on liquid precip too.

Today was another cloudy, rainy, and cool day. Newark received 1.61" of rain, which broke the daily record of 0.93" from 2006.

It will remain unseasonably cool through tomorrow. Some additional rain or showers are likely.

Afterward, a brief period of warmer readings will follow before another strong cold front crosses the region on Friday. All said, the first 10 days of October are on track to be much cooler than normal. The temperature will likely average 4°-6° below normal during the October 1-10 period.

Afterward, the pattern evolution will depend on the state of blocking and the influence of the cool ENSO Region 1+2 region.

Since 1950, 15/21 (71%) of cases with an ENSO Region 1+2 anomaly of -0.75°C or below were warmer than normal in the Middle Atlantic region, including Philadelphia and New York City. 48% were 1° or more above average in New York City and 62% were 1° or more above average in Philadelphia. Just 14% were 1° or more below normal in New York City while 24% were 1° or more below normal in Philadelphia. One-third of cases in both cities saw a monthly mean temperature of 60° or above. Overall, such ENSO conditions also favored warmth in the Central and Northern Plains, along with dry conditions in the Plains States.

October 1988 was the coldest exception. The closing week of September saw the coldest Region 1+2 anomaly since September 1988. That development raises the probability of a cooler exception this month.

The ENSO Region 1+2 anomaly was -1.7°C and the Region 3.4 anomaly was -0.8°C for the week centered around September 28. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.88°C and the ENSO Region 3.4 anomaly has averaged -0.88°C. La Niña conditions will likely persist through the fall.

The SOI was +32.81 today. The old daily record was +26.36, which was set in 2010.

The preliminary Arctic Oscillation (AO) was +1.066 today.

On October 2 the MJO was in Phase 4 at an amplitude of 0.929 (RMM). The October 1-adjusted amplitude was 0.822 (RMM).

Morning thoughts…

Today will be mostly cloudy with some periods of rain and continued cool. High temperatures will reach the upper 50s and lower 60s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 59°

Newark: 60°

Philadelphia: 63°

Tomorrow will turn warmer.

Normals:

New York City: 30-Year: 68.6°; 15-Year: 69.9°

Newark: 30-Year: 70.2°; 15-Year: 71.7°

Philadelphia: 30-Year: 71.4°; 15-Year: 72.6°

Impressive for Newark to get two record low maxes in a row. This is the first two consecutive records since the Memorial Day weekend in 2021. So the typical warm October La Niña pattern is getting overpowered by the North Pacific warm pool and more Nino-like +PNA.

Will it tho?   Sometimes these spinning wheels of crap like to keep the low level clouds around longer

It's as good as gone and it'll be gone for  a nice long time.

By the way, look towards the south, I can see large gaps in the clouds already with blue patches of sky visible in that direction.

This is why ENSO centric forecasts are going to have major issues (they've had issues for a few years now.)

The best we can do is identify which competing warm pools may pushback against the canonical ENSO expectations in the new era of ongoing marine heatwaves. In the old days, it was usually just ENSO and whether the NAO would be positive or negative. Now, a new layer of record SST warmth has added to the complexity with record SSTs in both the tropics and subtropics. So this is why seasonal model forecasts can be low skill when models don’t know which warm pool or pools will dominate.

Do you think that the LR weather modeling will be able to add this new layer of complexity programmed into it so that we can improve these forecasts, Chris?
