Wildfire smoke in the New York area.

An extended period of generally cooler than normal temperatures is ongoing. No return to summerlike heat is likely through the remainder of June. However, temperatures will gradually warm toward seasonal levels during the first week of July. Afterward, near to somewhat above normal readings will likely prevail through mid-month. The Desert Southwest will likely see its hottest temperatures so far this year during the weekend into early next week. As has been the case throughout June, extreme heat appears unlikely in the northern Mid-Atlantic region for the foreseeable future. The ENSO Region 1+2 anomaly was +2.9°C and the Region 3.4 anomaly was +1.0°C for the week centered around June 21. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.37°C and the ENSO Region 3.4 anomaly has averaged +0.77°C. El Niño conditions have developed and will likely continue to strengthen through at least the summer. The SOI was -0.35 today. The preliminary Arctic Oscillation (AO) was +0.753 today. On June 27 the MJO was in Phase 2 at an amplitude of 1.073 (RMM). The June 26-adjusted amplitude was 1.334 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a cooler than normal June (1991-2020 normal). June will likely finish with a mean temperature near 70.0° (2.0° below normal).

In the wake of record low seasonal snowfall for New York City (Central Park) and Bridgeport and the development of what could become a strong, and perhaps basin-wide El Niño event, it is worth looking back at how seasonal snowfall changed over the past 30 years relative to the prior 30-year period (1991-2020 vs. 1961-1990). In many parts of the Middle Atlantic region, seasonal snowfall had declined and variability of seasonal snowfall had increased. In the northern Mid-Atlantic and southern New England regions, seasonal snowfall had increased and variability in seasonal snowfall had increased. Bangor's figures have likely been impacted by the increasingly frequent and significant marine heatwaves off Maine's coast. As the climate continues to warm, cities such as New York City and Newark will likely see a decline in seasonal snowfall. That transition may already be in its early stages. By the mid-2030s, New York City's average seasonal snowfall could slip toward or below 20.0" based on rising winter temperatures. Mean seasonal snowfall and mean temperatures constructed from a regression equation (coefficient of determination: 0.836). When mean winter temperatures rise above 40.0°, seasonal snowfall totals could decrease and variability could also begin to decrease. That is the case with Atlanta and Richmond shown on the above chart and Greensboro listed on the below chart. Additional areas with mean winter temperatures of 40.0°F or above with decreased seasonal snowfall and decreased seasonal snowfall variability include Charleston (SC), Charlotte, and Wilmington (NC). Not all areas will likely see decreasing snowfall over the next decade. Central and northern New England could see additional increases in seasonal snowfall along with increased variability, as their winters remain colder than the thresholds at which seasonal snowfall begins to decline through at least the 2020s.

An extended period of generally cooler than normal temperatures is ongoing. No return to summerlike heat is likely through at least the first three weeks of June. Tomorrow will be fair and a bit warmer. The pleasantly warm readings will continue through the weekend. Parts of Texas are in the early stages of an extreme heat event. At present, there is no indication that this heat will move into the Middle Atlantic and southern New England regions. The ENSO Region 1+2 anomaly was +2.6°C and the Region 3.4 anomaly was +0.9°C for the week centered around June 7. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.28°C and the ENSO Region 3.4 anomaly has averaged +0.58°C. El Niño conditions have developed and will likely continue to strengthen through at least the summer. The SOI was +1.41 today. The preliminary Arctic Oscillation (AO) was +0.279 today. On June 12 the MJO was in Phase 3 at an amplitude of 1.439 (RMM). The June 11-adjusted amplitude was 1.382 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 66% probability that New York City will have a cooler than normal June (1991-2020 normal). June will likely finish with a mean temperature near 71.0° (0.8° below normal).

An extended period of generally cooler than normal temperatures is ongoing. No return to summerlike heat is likely through at least the first three weeks of June. Tomorrow will be variably cloudy and a bit cooler. Some showers and thundershowers are possible. Texas could see near record and record heat develop during the middle and latter part of the week. Already, Laredo saw a near record 110° high today. At present, there is no indication that this heat will move into the Middle Atlantic and southern New England regions. The latest ECMWF weeklies continue to show no significant heat until at least late in the month. The ENSO Region 1+2 anomaly was +2.6°C and the Region 3.4 anomaly was +0.9°C for the week centered around June 7. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.28°C and the ENSO Region 3.4 anomaly has averaged +0.58°C. El Niño conditions have developed and will likely continue to strengthen through at least the summer. The SOI was -1.69 today. The preliminary Arctic Oscillation (AO) was +0.601 today. On June 11 the MJO was in Phase 3 at an amplitude of 1.384 (RMM). The June 10-adjusted amplitude was 1.359 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 66% probability that New York City will have a cooler than normal June (1991-2020 normal). June will likely finish with a mean temperature near 71.0° (0.8° below normal).

Today will likely prove to be the warmest day this week. High temperatures included: New York City: 82°; Newark: 85°; Philadelphia: 89°; and, Washington, DC: 91°. Across the Atlantic, London reached 31°C (88°F) for the second consecutive day. No prior year had more than one 31°C temperature through June 15th. An extended period of generally cooler than normal temperatures is ongoing. No return to summerlike heat is likely through at least the first three weeks of June. A system will bring a general 0.25"-0.75" rainfall with locally higher amounts tomorrow into Tuesday. Some areas could experience thunder. The latest ECMWF weeklies have backed off the development of sustained warmer than normal conditions after the second week of June. The warmth is delayed until late in the month, but that's a low-skill forecasting range. The ENSO Region 1+2 anomaly was +2.3°C and the Region 3.4 anomaly was +0.8°C for the week centered around May 31. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.25°C and the ENSO Region 3.4 anomaly has averaged +0.50°C. El Niño conditions have developed and will likely continue to strengthen through at least the summer. The SOI was +10.54 today. The preliminary Arctic Oscillation (AO) was -0.484 today. On June 9 the MJO was in Phase 3 at an amplitude of 1.254 (RMM). The June 8-adjusted amplitude was 1.274 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 59% probability that New York City will have a cooler than normal June (1991-2020 normal). June will likely finish with a mean temperature near 71.3° (0.7° below normal).
