Hartford: 87° (old record: 88°, 1941)

Tomorrow will be another summerlike day. Temperatures will likely peak in the upper 80s in most of the region. The hot spots could approach or reach 90°. Long Island will be cooler with highs peaking in the 70s due to onshore breezes. 

Following the bout of early season heat, readings will return to the 70s to end the week and start the weekend. It will turn cooler on Sunday. A sharp cold shot is possible early next week.

Generally dry conditions will also persist through at least Friday.

The ENSO Region 1+2 anomaly was +1.5°C and the Region 3.4 anomaly was +0.2°C for the week centered around April 8. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.30°C and the ENSO Region 3.4 anomaly has averaged +0.07°C. Neutral ENSO conditions will continue through at least mid-spring.

The SOI was -9.45 yesterday. 

The preliminary Arctic Oscillation (AO) was -0.814 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 83% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 56.3° (2.6° above normal). 

Supplemental Information: The projected mean would be 3.3° above the 1981-2010 normal monthly value.

I'm fully prepared for a spring, summer, and fall of storms firing off well north and west and not making it here.  Already we've had two days of some media hype about storms with little to nothing to show in every location in the forum.  I'm watching that line out in western PA, and things are always possible, but it's likely to be a miss or fizzled out to sprinkles by the time any of it gets here.  

Our area might get lucky with something later on tonight.  Further east chances less.

Picked up .24” from lasts nights stuff.  I did sprinkle the grass seed earlier so I am not overly confident we get anything later.

Mid 80's still in NYC at this hour, in mid-april, is nuts.

 

Hoping those storms in PA make it here.  Had a nice downpour last night.

With today's 90° high in Central Park, 2026 became only the third year on record with a high of 80° or above in March and a high of 90° or above in April. The only prior years were 1977 and 1990.

Some distant lightning visible here from storms in CT. Too bad not a chance in hell any reach me.

Plus if we have a trough sitting in that location we’ll be socked in low clouds on east wind struggling to get to 50. 

Yeah, we may get one of our famous spring cut-off low patterns.
