Look at 1944, 1949 and 1959 putting in such strong performances on all standings! 1953 putting in a strong performance on number of 100 degree days.

I knew we had some real roasters back then but this is very extreme.

Beautiful day today

Bring on the rain

[donsutherland1]

Tomorrow will be dry and continued pleasant. Temperatures will generally top out in the lower 70s. Showers and/or thundershowers are possible Tuesday night into Wednesday. It will turn somewhat warmer on Thursday and the week could end with temperatures in the upper 70s to perhaps 80°.

Meanwhile, parts of Texas will see extreme heat. The temperature could approach or set new May monthly high temperature records in such cities as Austin, Del Rio and San Antonio on Wednesday.

The extended guidance has grown cooler for the second half of May than it had been. Both the CFSv2 and ECMWF weekly guidance are now in good agreement that the second half of the month could average near normal overall.

The ENSO Region 1+2 anomaly was +0.1°C and the Region 3.4 anomaly was -0.1°C for the week centered around April 30. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.68°C and the ENSO Region 3.4 anomaly has averaged -0.05°C. Neutral ENSO conditions will likely continue through at least early summer.

Early indications are that summer 2025 will be warmer than normal in the New York City and Philadelphia areas. The potential exists for a much warmer than normal summer (more than 1° above normal).

The SOI was -0.82 today.

The preliminary Arctic Oscillation (AO) was +0.718 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied near 76% probability that New York City will have a warmer than normal May (1991-2020 normal). May will likely finish with a mean temperature near 65.6° (2.4° above normal).

Don, when will the clouds move in make our skies overcast?  No sun from tomorrow through Saturday?

It will become mostly cloudy but still dry between 6 am and 8 am. With perhaps a light shower, it should be mainly or completely dry into the evening. Clouds could break for a time on Friday. More sustained clearing should commence Saturday afternoon. At least, that's where things currently stand.
