A shower or thundershower is possible tonight into early tomorrow. Afterward, tomorrow will be pleasantly warm with highs in the lower to perhaps middle 80s. Some showers are possible tomorrow night and then again Friday night or Saturday. A warming trend could commence on Sunday. The guidance increasingly suggests that hot weather could return to conclude June and start July. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -18.28 yesterday. The preliminary Arctic Oscillation (AO) was +0.424 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 94% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.4 (1.4° above normal). Supplemental Information: The projected mean would be 2.0° above the 1981-2010 normal monthly value.

Today was another day of furnace-like heat in France, Jersey, and the UK. The extreme heat will shift eastward over the next few days.

The Paris-Montouris station, for which records go back to 1872, has recorded its first case of two consecutive 40°C (104°F) or above days. Paris-Jardin du Luxembourg topped out at 41.2°C (106.2°F). Jersey (Maison St. Louis: 39.3°C/102.7°F) and Switzerland (Basel: 38.0°C/100.4°F) set national all-time records. The UK (Merrifield: 36.7°C/98.1F) set a national June monthly record.

The official announcement from Météo-France: Translation: June 24, 2026 France has just experienced its hottest day ever recorded. Across the country, the average temperature over 24 hours reached 30°C, exceeding the 29.9°C measured... the day before, which was already the hottest day ever recorded since measurements began in 1947.

It showed up on the list of all-time records, so I noted it.

Tomorrow and Friday will be pleasantly warm days with highs in the lower 80s. Some showers are possible tomorrow night and then again Friday night or Saturday. A warming trend could commence during or after the next weekend. Some of the guidance suggests that hot weather could return to conclude June. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -22.92 yesterday. The preliminary Arctic Oscillation (AO) was +0.406 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 91% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.5 (1.5° above normal). Supplemental Information: The projected mean would be 2.1° above the 1981-2010 normal monthly value.

Paris, like NYC, has multiple sites. I referenced one such site.

I agree. Indeed, one location in coastal France beat its all-time record that was set just yesterday by 4.0C (7.2F).

"Intense heat destroys even the temper of steel..."-George Prentice. It was that kind of day in France, Spain, and the UK today. In Paris, no relief was found under the trees of Jardin du Luxembourg as the mercury rose to 42.2C (108.0F). The UK recorded its hottest June temperature on record with a high of 36.1C (97.0F) at Gosport. As a result of the ongoing heatwave, which is France's worst June heatwave on record, 2026 already accounts for the second most all-time record high temperatures for any calendar year.

Those were monthly records. 13 all-time records were broken at stations with 80+ year climate records.

Any showers will depart this evening. It will turn somewhat warmer for tomorrow through Friday will likely see highs in the lower 80s. Some showers are possible as a warm front moves across the region on Friday or Saturday. A warming trend could commence during or after the next weekend. Some of the guidance suggests that hot weather could return to conclude June. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -19.68 yesterday. The preliminary Arctic Oscillation (AO) was +0.369 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 90% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.7 (1.7° above normal). Supplemental Information: The projected mean would be 2.3° above the 1981-2010 normal monthly value.

It was a surreal day in France. The air was "a furnace breath." The "heatquake" toppled, shattered, and demolished more than 100 all-time high temperature records. June 2026 has surpassed June 2019 for setting the most all-time record highs in the month of June.

Very tragic. Unfortunately, there will almost certainly be many more fatalities across Europe as the heat dome expands.

Through 6 pm, rainfall amounts included: Bridgeport: 0.78" Islip: 0.07" New York City: 0.58" Newark: 1.00" White Plains: 0.50" Showers and periods of rain will likely continue into early tomorrow. Some locations could experience a thunderstorm. A general 0.50"-1.50" rainfall is likely. Some locally higher amounts are possible. Following the storm, readings will reach the middle and upper 70s tomorrow. Wednesday through Friday will likely see highs in the lower 80s. Some showers are possible as a warm front moves across the region on Friday. A warming trend could commence during or after the next weekend. Some of the guidance suggests that hot weather could return to conclude June. The ENSO Region 1+2 anomaly was +3.0°C and the Region 3.4 anomaly was +1.7°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.42°C and the ENSO Region 3.4 anomaly has averaged +1.22°C. The ongoing El Niño will continue to strengthen through the summer. The SOI was -19.68 today. The preliminary Arctic Oscillation (AO) was +0.029 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 90% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.8 (1.8° above normal). Supplemental Information: The projected mean would be 2.4° above the 1981-2010 normal monthly value.

It will be interesting to see how this ultimately plays out. I suspect that the Sonoran Desert has yet to see its highest temperatures this summer, even if the forecast values for this week verify.
