In the wake of yesterday's historic October heat, much cooler air returned to the region. Under clouds and occasional rain, readings remained in the 50s from New Jersey into New England. Meanwhile, farther south, the historic autumn heat toppled additional daily and monthly records. Today, Raleigh reached 100°, its latest 100° reading on record. The previous latest such reading occurred on September 10, 2007 when the temperature also hit 100°. As a result of today's October record high temperature, Raleigh's highest annual temperature for this year will occur in October for the first time on record. Raleigh's records go back to 1887. With its 101° degree high temperature, Birmingham registered its 8th consecutive daily record high temperature. Previously, the city had two 7-day stretches (September 3-9, 1925 and May 16-22, 1962). Birmingham also recorded its highest annual temperature for 2019 in October, the first time that occurred. Records there go back to 1895. Records included: Athens, GA: 100° (new October record) Atlanta: 98° (new October record) Augusta, GA: 100° (new October record) Birmingham: 101° Charlotte: 98° Chattanooga, TN: 100° (tied October record set yesterday) Columbia, SC: 100° Columbus, GA: 100° (tied October record) Crestview, FL: 101° (new October record) Elizabeth City, NC: 96°(new October record) Greenville-Spartanburg, SC: 98° (new October record) Huntsville, AL: 100°(tied October record set yesterday) Macon, GA: 102° (new October record) Mobile: 98° (new October record) Montgomery, AL: 102° (new October record) Nashville: 99° (tied October record set yesterday) Pensacola: 97° (new October record) Raleigh: 100° (new October record) Richmond: 97° Savannah: 96° Tallahassee: 97° (new October record) Tuscaloosa, AL: 101° (tied October record set yesterday) Wilmington, NC: 98° (new October record)　 Today was also Atlanta's 90th 90° or above temperature this year. That ties the annual record set in 1980 and tied in 2011. Today was also Atlanta's 13th 90° or above temperature after September 15. The previous record was 11, which was set just last year. The ENSO Region 1+2 anomaly was -0.5°C and the Region 3.4 anomaly was +0.5°C for the week centered around September 25. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.73°C and the ENSO Region 3.4 anomaly has averaged -0.07°C. The recent strong cooling in Region 1+2 indicates that the prospects for a neutral-cool ENSO during the winter have continued to increase. Since 1991 when weekly ENSO region data was available, five years have seen September record 2 or more weeks with -1.0°C or cooler weekly anomalies in Region 1+2: 1996, 1999, 2007, 2010, and 2017. 4/5 (80%) of those cases went on to feature warm December-February temperature anomalies in the Middle Atlantic and southern New England regions. Those cases include La Niña winters. However, the larger pool of neutral-cool ENSO winters, many of which predate the weekly ENSO regional data, have often featured frequent Atlantic blocking. For now, there is a mixed winter signal. The SOI was -20.44 today. Today, the preliminary Arctic Oscillation (AO) figure was -0.423. Since 1950, there have been five prior cases when the AO averaged -0.500 or below in both July and August: 1950, 1958, 1960, 1968, and 2015. The average temperature for September through November in New York City was 58.9° (59.6° adjusted). All cases featured a warmer than normal fall. The potential for autumn 2019 to rank among the 30 warmest cases on record has increased in recent weeks. For New York City, that would translate into a September-November mean temperature of at least 58.8°. The latest EPS weeklies show a return to warm anomalies in the East after the second week in October. While the timing is far out, the EPS weeklies also suggest that the warmth could roll into the start of November. On October 2, the MJO was in Phase 1 at an amplitude of 1.729 (RMM). The October 1-adjusted amplitude was 1.758. Based on sensitivity analysis applied to the latest guidance, the implied probability of New York City having a warmer than normal October is approximately 59%. 　

This afternoon, the temperature reached 100° at Raleigh. That broke the October record of 98°, which was set on October 6, 1954. It is also the latest 100° or above temperature on record. The previous latest such temperature occurred on September 10, 2007. 2019 also becomes the first year on record when Raleigh's highest annual temperature was reached in October. Records go back to 1887.

As of 2 pm, Wilmington, NC had a high temperature of 96°. That surpassed the previous October record of 95°, which was set on October 5, 1954 and tied on October 3, 1986.

As of 2 pm, Raleigh had a high temperature of 99°. That surpassed the 98° reached on October 6, 1954 to become the warmest October temperature on record.

As of 2 pm, Atlanta has had a high temperature of 97°. That surpasses yesterday's 96° reading as the highest on record for October.

This is a big and sad tragedy.

At 11 am CDT, the temperature at Birmingham reached 95°. That surpassed the daily record of 93°, which was set in 1911. Birmingham has now recorded daily record high temperatures on 8 consecutive days. That surpasses the old record of 7 consecutive days, which was set in 1925 and tied in 1962. 7-Consecutive Daily Record High Temperatures: September 3-9, 1925 May 16-22, 1962 (1962 recorded 16 record high temperatures in May)

I agree. Such a consumption tax would generate revenue and it would have the desired impact of reducing carbon-intensive consumption. The CBO provided a summary related to a potential $25 per ton carbon tax last year: https://www.cbo.gov/budget-options/2018/54821

IMO, markets will need to be leveraged, not supplanted, to offer perhaps the highest probability that the challenge of anthropogenic climate change is met. Policy that aims to supplant markets will probably run aground.

It should be noted that the above is political commentary by a Senate candidate. Policy and political discussions related to climate change are not necessarily the same thing as scientific discussions.

Cut Bank fell to 1° yesterday.

Today saw more historic heat across parts of the South. For the first time on record, Birmingham's annual maximum temperature was recorded in October. Tuscaloosa's 101° figure tied the high temperature of 9/13 for the year's hottest reading. Select records (and the list is not all-inclusive): Athens, GA: 98°(tied October record) Atlanta: 96° (new October record) Baltimore: 98° (new October record) ***59th 90° day ties record set in 2010*** Birmingham, AL: 103° (new October record) ***first annual high temperature in October; records go back to 1895; previous latest such temperature 9/9 in 1925*** Charlotte: 99° (new October record) Huntsville, AL: 100° (new October record) Lexington, KY: 96° Louisville: 96° Macon, GA: 98° Mobile, AL: 96° Montgomery, AL: 99° Nashville: 99° (new October record) Norfolk: 97° (new October record) Pensacola: 93° Raleigh: 96° Richmond: 98° Sterling, VA: 96° (new October record) Tuscaloosa, AL: 101°(new October record) ***tied the 9/13/2019 reading for the hottest this year; first October entry in the record book; records go back to 1948*** Washington, DC: 98° (new October record) Distribution of Birmingham's Highest Annual Temperature by Month (1895-2019) May: 3 (2.1%) June: 28 (19.3%) July: 53 (36.6%) August: 43 (29.7%) September: 17 (11.7%) October: 1 (0.7%) Note: The numbers add up to more than the 125-year record, because some years saw the highest annual temperature occur in more than one month.

Much of the region experienced its hottest October day on record. Records included: Allentown: 93° (new October record) Athens, GA: 98°(tied October record) Atlanta: 96° (new October record) Baltimore: 98° (new October record) ***59th 90° day ties record set in 2010*** Birmingham, AL: 103° (new October record) ***first annual high temperature in October; records go back to 1895*** Bridgeport: 87° Charlotte: 99° (new October record) Harrisburg: 93° Huntsville, AL: 100° (new October record) Islip: 89° (new October record) Lexington, KY: 96° Louisville: 96° Macon, GA: 98° Mobile, AL: 96° Montgomery, AL: 99° Nashville: 99° (new October record) New York City-Central Park: 93° New York City-JFK: 95° (new October record) New York City-LGA: 95° (new October record) Newark: 96° (new October record) Norfolk: 97° (new October record) Pensacola: 93° Philadelphia: 95° Poughkeepsie: 88° Raleigh: 96° Richmond: 98° Sterling, VA: 96° (new October record) Tuscaloosa, AL: 101°(new October record) Washington, DC: 98° (new October record) White Plains, NY: 90° (new October record) Wilmington, DE: 98° (new October record) Much cooler air is now pushing into the region. Tomorrow will likely see temperatures struggling to reach 60°. Overall, a 7-10 day period with readings generally near or below normal lies ahead. The ENSO Region 1+2 anomaly was -0.5°C and the Region 3.4 anomaly was +0.5°C for the week centered around September 25. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.73°C and the ENSO Region 3.4 anomaly has averaged -0.07°C. The recent strong cooling in Region 1+2 indicates that the prospects for a neutral-cool ENSO during the winter have continued to increase. Since 1991 when weekly ENSO region data was available, five years have seen September record 2 or more weeks with -1.0°C or cooler weekly anomalies in Region 1+2: 1996, 1999, 2007, 2010, and 2017. 4/5 (80%) of those cases went on to feature warm December-February temperature anomalies in the Middle Atlantic and southern New England regions. Those cases include La Niña winters. However, the larger pool of neutral-cool ENSO winters, many of which predate the weekly ENSO regional data, have often featured frequent Atlantic blocking. For now, there is a mixed winter signal. The SOI was -11.93 today. Today, the preliminary Arctic Oscillation (AO) figure was -0.443. Since 1950, there have been five prior cases when the AO averaged -0.500 or below in both July and August: 1950, 1958, 1960, 1968, and 2015. The average temperature for September through November in New York City was 58.9° (59.6° adjusted). All cases featured a warmer than normal fall. The potential for autumn 2019 to rank among the 30 warmest cases on record has increased in recent weeks. For New York City, that would translate into a September-November mean temperature of at least 58.8°. Events during September, including the SOI's falling to -35.30 on September 19, the MJO's being in Phase 1 at an amplitude of 2.000 or above during the September 20-30 period for more than two days, the historic late September snowfall in Great Falls, MT, and the possible ongoing evolution toward a generally positive AO regime, favor a warmer than normal October based on past outcomes. On October 1, the MJO was in Phase 1 at an amplitude of 1.766 (RMM). The September 30-adjusted amplitude was 1.909. Based on sensitivity analysis applied to the latest guidance, the implied probability of New York City having a warmer than normal October is approximately 58%.

Record highs around NYC included: Bridgeport: 87° Islip: 89° (new October record) New York City-Central Park: 93° New York City-JFK: 95° (new October record) New York City-LGA: 95° (new October record) Newark: 96° (new October record) White Plains: 90° (new October record)

JFK had a 4 pm temperature of 94°.

Yes. This is an extremely impressive outbreak of heat.

In parts of the South, monthly record high temperatures were shattered. Monthly records included: Birmingham: 99° (previous October record: 94°, 10/1/1919, 10/5/1927, and 10/6/1954) Chattanooga, TN: 97° (previous October record: 94°, 10/5/1954) Huntsville, AL: 99° (previous October record: 96°, 10/8/1911) Lexington, KY: 97° (previous October record: 93°, 10/6/1941) Louisville: 96° (previous October record: 93°, 10/7-8/2007) Mobile: 97° (previous October record:95°, 10/2/1904) Montgomery, AL: 101° (previous October record: 100°, 10/6/1954) Nashville: 98° (previous October record: 95°, 10/1/1953, 10/5/1954, and 10/8/2007) Pensacola: 96° (previous October record: 95°, 10/8/1884 and 10/5/1951)

Today was a day of records in many parts of the United States. In the wake of a historic late September snowstorm, record low temperatures were recorded in parts of Montana. Records included: Cut Bank: 1°(old record: 14°, 1950) Great Falls: 9° (old record: 22°, 1959) In parts of the East, monthly record high temperatures were shattered. Monthly records included: Akron: 91° (previous October record: 89°, 10/1/1927 and 10/5/1922) Birmingham: 99° (previous October record: 94°, 10/1/1919, 10/5/1927, and 10/6/1954) Cleveland: 93° (previous October record: 90°, 10/6/1946) Huntsville, AL: 99° (previous October record: 96°, 10/8/1911) Lexington, KY: 97° (previous October record: 93°, 10/6/1941) Louisville: 96° (previous October record: 93°, 10/7-8/2007) Nashville: 98° (previous October record: 95°, 10/1/1953, 10/5/1954, and 10/8/2007) Pensacola: 96° (previous October record: 95°, 10/8/1884 and 10/5/1951) Some of this warmth will push into the Mid-Atlantic region tomorrow. Temperatures will likely reach the middle and upper 80s into parts of southern New England. Locations, including Washington, Baltimore, Philadelphia, Newark, and possibly even New York City could reach 90°. The last October 90° or above temperature for select locations occurred on the following dates: Baltimore: October 15, 2015, 90° New York City-Central Park: October 6, 1941, 90° New York City-JFK Airport: October 8, 2007, 90° New York City-LaGuardia Airport: October 6, 1946, 90° Newark: October 6, 1959: 91° Philadelphia: October 7, 1941: 93° Washington, DC: October 4, 2018, 90° Afterward, a period of cooler than normal readings will move into the region during the latter part of the first week of October. This pattern could last 7-10 days, though not every day will be cooler than normal. 　 The ENSO Region 1+2 anomaly was -0.5°C and the Region 3.4 anomaly was +0.5°C for the week centered around September 25. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.73°C and the ENSO Region 3.4 anomaly has averaged -0.07°C. The recent strong cooling in Region 1+2 indicates that the prospects for a neutral-cool ENSO during the winter have continued to increase. Since 1991 when weekly ENSO region data was available, five years have seen September record 2 or more weeks with -1.0°C or cooler weekly anomalies in Region 1+2: 1996, 1999, 2007, 2010, and 2017. 4/5 (80%) of those cases went on to feature warm December-February temperature anomalies in the Middle Atlantic and southern New England regions. Those cases include La Niña winters. However, the larger pool of neutral-cool ENSO winters, many of which predate the weekly ENSO regional data, have often featured frequent Atlantic blocking. For now, there is a mixed winter signal. The SOI was +2.32 today. Today, the preliminary Arctic Oscillation (AO) figure was not available. Since 1950, there have been five prior cases when the AO averaged -0.500 or below in both July and August: 1950, 1958, 1960, 1968, and 2015. The average temperature for September through November in New York City was 58.9° (59.6° adjusted). All cases featured a warmer than normal fall. The potential for autumn 2019 to rank among the 30 warmest cases on record has increased in recent weeks. For New York City, that would translate into a September-November mean temperature of at least 58.8°. Events during September, including the SOI's falling to -35.30 on September 19, the MJO's being in Phase 1 at an amplitude of 2.000 or above during the September 20-30 period for more than two days, the historic late September snowfall in Great Falls, MT, and the possible ongoing evolution toward a generally positive AO regime, favor a warmer than normal October based on past outcomes. On September 30, the MJO was in Phase 1 at an amplitude of 1.909 (RMM). The September 29-adjusted amplitude was 2.041. Based on sensitivity analysis applied to the latest guidance, the implied probability of New York City having a warmer than normal October is approximately 60%.

At 1 pm, the temperature was 91° in Cleveland. That set a new October high temperature record. The previous monthly record was 90°, which was set on October 6, 1946.

Utqiagvik (formerly Barrow) remains solidly on course to experience its first September on record with a mean temperature of 40.0° or above. At present, a figure of 40.5° +/- 0.1° appears likely. Based on sensitivity analysis, there is an implied 97% probability of a 40.0° or above mean temperature. The current record is 37.7°, which was set in 1998. Overall, summer 2019 featured historic warmth in Alaska. Anchorage had its first 90° day. The meteorological summer mean temperature of 62.8° exceeded the mean figure for the hottest month on record prior to 2019 by 0.1°. In an opinion piece published in The New York Times three scientists, Vera Trainer, Rick Thoman, and Gay Sheffield, wrote about the impact climate change is having on Alaska and its environs. In part, they explained: Nome lies south of the Arctic Circle, on the edge of the Seward Peninsula along the northern Bering Sea. The peninsula is the closest point of the North American mainland to Russia. Months of darkness and daylight alternate there. And the effects of the warming climate are front and center. In June, people there told us, they watched a herd of musk ox retreat to small patches of snow that lingered in the hills as they panted through a three-day heat wave of temperatures at and above 80 degrees Fahrenheit. The normal daily maximum in June is 54.9 degrees. More ominous, the ocean is now free of ice most of the year; not that long ago, ice covered the sea near Nome generally from early November to late May. The ice is crucial to the sea life that is central to the people who live there... Over past centuries, the temperature gradient at the edge of the sea ice near Nome was a signal to marine animals that food was plentiful. Melting ice provides nutrients that fuel plankton blooms when sunlight is sufficient for photosynthesis. This ice melt during warmer, sunny days provides a banquet of plankton for small fish, shellfish and baleen whales. Those whales and other marine creatures typically followed the retreating ice, feasting as they hugged the Alaska coastline. Now whales often show up emaciated because the timing and extent of the ice melt has changed. The system is out of sync. The ice melt happens too early in the season, when shorter days and lack of sunlight are insufficient to nourish the algae blooms. What’s also troubling is the recent discovery of enormous cyst beds, the seedlike dormant resting stages of ocean algae, in ocean sediments in the Chukchi Sea, north of the Bering Strait. Unlike the nourishing blooms that bring life to the waters of Nome, these cysts can hatch into toxic algal blooms when the ocean warms. The toxins produced by these algae were recently detected at low levels in over a dozen species of marine mammals throughout Alaska, many of which are consumed by Native Alaskans. These algal toxins were also identified in dead sea birds — murres, fulmars and storm petrels — found during an unusual die-off in Alaska beginning in 2015. https://www.nytimes.com/2019/09/25/opinion/climate-change-ocean-Arctic.html
