donsutherland1 Posted May 31 Share Posted May 31 Galveston experienced its warmest December on record last year with a mean temperature of 69.9°, which crushed the old mark of 66.4° that had stood since 1889. The December temperature average was warm enough to qualify as that city's 7th warmest November on record. Since then, one or more record-breaking or record-tying high temperatures were set in each month. April 2022 was the warmest April on record with a mean temperature of 75.5° (old record: 75.0°, 1967 and 2017). Just five months after the historic December warmth, May experienced historic warmth that demolished the monthly record that was set in 2018.The combination of dry conditions, development of a persistent heat dome, and much warmer than normal water temperatures amplified by the impact of climate change produced the record outcome. Summary information on the impacts of climate change in the Houston and Galveston areas can be found here:https://www.globalchange.gov/sites/globalchange/files/CCPR_HOU_brochure-final.pdfFor background information, the mean temperature rose 2.0° at Galveston from the 1961-1990 period to the 1991-2020 period. The number of 90° days rose particularly sharply. Annual temperature: 1961-90: 69.7°; 1991-20: 71.7°Number of days with highs of 80° or above: 1961-90: 151.0 days; 1991-20: 175.7 daysNumber of days with highs of 85° or above: 1961-90: 92.3 days; 1991-20: 126.0 daysNumber of days with highs of 90° or above: 1961-90: 13.5 days; 1991-20: 58.2 daysNumber of days with lows of 80° or above: 1961-90: 52.1 days; 1991-20: 62.3 daysThe last year with fewer than 100 85° days was 1997 when there were 94 such days. The last year with fewer than 20 90° days was 1992 when there were just 7 such days.80° warmth has now been occurring both earlier and later in the season as the "hot" season lengthens.Number of days with highs of 80° or above in March-April: 1961-90: 1.1 days; 1991-20: 4.3 daysNumber of days with highs of 80° or above in November-December: 1961-90: 0.5 days; 1991-20: 1.8 daysThe synoptic pattern, regional drought, and warm sea surface temperatures occurred against the backdrop of a warming climate that was resulting in a dramatic increase in hot days. As a result, May 2022 essentially rewrote the record book for warmth in May.

StormchaserChuck! Posted June 1 Share Posted June 1 Really cool, I noticed record High pressure in the SW and Alaska/warming, but I didn't think it would penetrate moisture. They are right on the GOM. Link to comment Share on other sites More sharing options...

donsutherland1 Posted June 1 Author Share Posted June 1 The impact of climate change can be seen from Galveston's monthly temperature records. None of Galveston's cold monthly records occurred during or after 2000. In contrast, 9 of the 12 warm monthly records occurred since 2000; 8 of 12 occurred since 2010; and, 4 of 12 have occurred since 2020. In terms of annual records, the coldest year was 1979 with a mean temperature of 67.7°. The coldest year since 2000 was 2010 with a mean temperature of 70.2°. 2010 ranked as the 72nd coldest year overall. The warmest year was 2017 with a mean temperature of 74.4°. All of the 10 warmest years have occurred since 2000. For perspective, the 2000s currently account for 15.1% of Galveston’s climate record (May 1874 through May 1875).

donsutherland1 Posted June 2 Author Share Posted June 2 With a high temperature of 92° as of 2 pm CDT, Galveston has now had 5 consecutive days with high temperatures of 90° or above. The 5/29-6/2 period is the earliest such stretch of 5 consecutive days. The old record was 5/31-6/4/1875. Link to comment Share on other sites More sharing options...

Roger Smith Posted June 3 Share Posted June 3 At the same time it has been record cold in the Pac NW and southern BC, anomalies in WA state were close to -5 F deg. I live near the border north of Spokane and our trees only finished their normal mid-May full foliation cycle today. We can still see snow on top of nearby hills with summits of 7,000 to 8,000 ft. Last week there was still snow on even lower hilltops reaching 6,000 ft. Certainly normal to see snow on alpine slopes around here into July, but these lower hills are usually free of snow by early to mid May. As a result there was no spring flooding at all in the region as a lot of the snow is still up there. In 1948 a similar weather pattern turned very warm with heavy rain, and historic floods hit both the Fraser and Columbia Rivers. It was the end of June last year when we had the unprecedented heat dome and highs around here of 110 F. Hoping we don't see that this summer although even in a normal summer you can expect a few days in the 100-105 F range. 1 Link to comment Share on other sites More sharing options...

Vice-Regent Posted June 13 Share Posted June 13 Probably another residual of the AMOC situation because the Gulf of Mexico relies on oceanic transport to reduce it's heat content and the climate of Galveston is highly correlated with sea surface temperature. 2 Link to comment Share on other sites More sharing options...
donsutherland1 Posted June 16 Author Share Posted June 16 At Galveston, which has seen two consecutive warm monthly records, June 1-15 was, by far, the warmest first half of June on record. The mean temperature was 87.1°. The old record was 85.3°, which was set in 2018. Galveston has already seen 9 days with low temperatures of 83° or above. The previous record for the entire month was 7 days. That record was set in 1994. Records go back to June 1874. Link to comment Share on other sites More sharing options...

StormchaserChuck! Posted June 20 Share Posted June 20 Lack of rainfall in Florida has something to do with it, I think. Watching the radar, it doesn't rain like it used to. sea-breeze fronts used to intersect middle of state. GOM SSTs Link to comment Share on other sites More sharing options...

No relief. 2 Link to comment Share on other sites More sharing options...
