donsutherland1 Posted June 30, 2021 Share Posted June 30, 2021 It was another hot day across the region. Temperatures rose into the lower and middle 90s in many places. 90° or above high temperatures included: Albany: 92° Allentown: 96° Atlantic City: 93° Baltimore: 97° Bangor: 93° Binghamton: 91° (old record: 90°, 2012) Boston: 99° (tied record set in 1933) Bridgeport: 94° (old record: 93°, 1959) Burlington: 93° Concord: 96° Harrisburg: 97° Hartford: 99° (old record: 98°, 1934) New York City-JFK: 90° New York City-LGA: 98° (tied record set in 1959 and tied in 2012) New York City-NYC: 95° Newark: 102° (old record: 100°, 1934 and 1959) ***Tied June Record*** Philadelphia: 95° Portland: 96° (tied record set in 1944) Poughkeepsie: 97° Providence: 97° (old record: 96°, 1934) Scranton: 97° (old record: 96°, 1959) Trenton: 93° Washington, DC: 93° Wilmington, DE: 94° Worcester: 93° The hot and humid air mass will remain in place over the Middle Atlantic and southern New England areas through tomorrow. Under partly sunny skies, temperatures will likely reach the middle and upper 90s in many parts of the region. The hottest spots will likely reach or exceed 100°. A shower or thundershower is possible especially during the afternoon and evening. Out West an unprecedented heat event shattered additional high temperature records. Preliminary high temperatures included: Boise: 105° (tied record set in 2008) Dallesport, WA: 107° (tied record set in 2008) Fort Nelson, BC: 97° (old record: 85°, 1983) Hermiston, OR: 118° (old record: 102°, 2015) ***New All-Time Record*** Kamloops, BC: 116° (old record: 102°, 2008) ***New All-Time Record*** Lillooet, BC: 116° (old record: 103°, 2008) ***New All-Time Record*** Lytton (RCS), BC: 121° (old record: 104°, 2008) ***New All-Time Record; New National Record for Canada*** Pasco, WA: 113° (old record: 105°, 2008) Pendleton, OR: 117° (old record: 102°, 1904 and 2008) ***New June Record*** Portland: 93° Redmond, OR: 112° (old record: 100°, 2008) ***New All-Time Record*** Spokane: 109° (old record: 98°, 1939) ***New All-Time Record*** Vancouver: 90° (old record: 83°, 1995) Walla Walla, WA: 116° (old record: 105°, 2008) ***New All-Time Record*** Yakima, WA: 113° (old record: 103°, 1948) ***New All-Time Record*** The heat will continue shift slowly to the north and east. Readings will remain much above normal in parts of eastern Washington State, Oregon, Idaho, and eastern British Columbia Climate change has increased the frequency, magnitude, and duration of extreme heat events in the United States and worldwide. Climate change has increased the frequency, magnitude, and duration of extreme heat events in the United States and worldwide. Further increases are likely in coming decades as the world's climate continues to warm. In large part on account of Phoenix's recent extreme heat event, there is an implied near 100% probability that June 2021 will become Phoenix's warmest June on record with a mean temperature near 95.2°. The existing record of 94.8° was set in 2013 and tied in 2016. The ENSO Region 1+2 anomaly was +0.2°C and the Region 3.4 anomaly was 0.0°C for the week centered around June 23. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.17°C and the ENSO Region 3.4 anomaly has averaged -0.20°C. Neutral ENSO conditions will likely prevail through August. The SOI was +0.77 today. The preliminary Arctic Oscillation (AO) figure was +0.869 today. On June 27 the MJO was in Phase 1 at an amplitude of 1.697 (RMM). The June 26-adjusted amplitude was 1.545 (RMM). In late April, the MJO moved through Phase 8 at an extreme amplitude (+3.000 or above). Only February 25, 1988 and March 18-19, 2015 had a higher amplitude at Phase 8. Both 1988 and 2015 went on to have an exceptionally warm July-August period. July-August 1988 had a mean temperature of 79.1°, which ranked 4th highest for that two-month period. July-August 2015 had a mean temperature of 78.9°, which ranked 5th highest for that two-month period. September 2015 was also the warmest September on record. The MJO's extreme passage through Phase 8 could provide the first hint of a hot summer. Since 1896, 76% of years that saw Phoenix reach 115° or above in June, as occurred this year, had a warmer than July-August in the Middle Atlantic region. The ratio of top 30 July-August temperatures relative to bottom 30 temperatures was 6:1 in favor of the warmth. Overall, the ingredients continue to fall into place for a warmer than normal to potentially hot summer. Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 74.3° (2.3° above normal). 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted June 30, 2021 Share Posted June 30, 2021 Morning thoughts... Following a night in which the prior day’s intense heat hung on despite the sun’s departure, another stifling day will follow. It will be partly sunny and very hot today. Near record and record heat is possible in parts of the area. There could be afternoon or evening showers and thunderstorms. Temperatures will likely reach the middle and upper 90s in most places today. Likely high temperatures around the region include: New York City (Central Park): 96° Newark: 101° Philadelphia: 97° Normals: New York City: 30-Year: 83.6°; 15-Year: 83.8° Newark: 30-Year: 85.9°; 15-Year: 86.3° Philadelphia: 30-Year: 86.9°; 15-Year: 87.4° Daily Records: New York City-LGA: 97°, 1945 and 1964 Newark: 99°, 1964 Tonight into Friday have the potential to see a general 1.00”-2.00” rainfall across the region with some locally higher amounts. Highest amounts could exceed 3.00”. Link to comment Share on other sites More sharing options...

bluewave Posted June 30, 2021 Share Posted June 30, 2021 The new NYC micronet is proving to be a valuable resource. We continue to see other stations in Queens with warmer high temperatures than LGA. The lows all stayed at 80° or above. LGA…………….…….98…81 Astoria………….….99…81 Corona……………..100..80 Queensbridge…..99…80 2 Link to comment Share on other sites More sharing options...

SACRUS Posted June 30, 2021 Share Posted June 30, 2021 Hot town summer in the city. Mid / upper 90s on tap today. High launch pad may get LGA 100 or > and EWR again. Western Atlantic ridge begins to move offshore today with one more day of high heat. Storms should be more prevalent today as heat dome is displaced where it peaked at 598DM ridge . Slow to move front and storms Thu (7/1) - Sun (7/4) - morning should bring heavy rains over the 60 - 72 hour period 2 - 4 inches of rain. Models kinder for the fourth of July as brunt of the rain and storms falls Thu - Sat morning, then unsettled showers Saturday and sunday morning. At this point models may be lining up to salvage the 4/5th. Not completely rain free / but looks more scattered and light. July 6 and beyond - heights and heat rise and resume with more 90s and humidity the work week as piece of the high heat out west bleeds east ahead of the Western Atlantic Ridge expansion. Need to watch some tropical system near FL early next week and if the re-expanding W . Atl Ridge steers it up the EC. Overall warm to hot summer continues. 1 Link to comment Share on other sites More sharing options...
