    Tough to keep track of all these rainfall records in recent years. https://x.com/tararosenblum/status/1793651432765186428

    While we are averaging above normal, the high end temps here this spring have been muted. Places like Newark will finish spring near the low end of the 90° day count. Plenty of rainfall and convection like this morning along with enhanced onshore flow.

    Nice Canadian airmass for the cooler weather fans by this time next week. So we still haven’t reached the point of extended heat yet. It’s been a challenge with all the onshore flow and clouds along with the rain.

    The HRRR has convection with a MCV.

    Yeah, it was my warmest day of the spring so far at 82° here just east of KHVN.

    Memorial Day could feature near record tropical PWATS approaching 2.00” for our area along with near record highs close to 100° in Florida. There will be a deepening low crossing the Great Lakes. So strong to severe storms could be an issue with very heavy downpours and possible flooding where the best training sets up.
  8. bluewave
    Yeah, I just noticed the same thing.
  9. bluewave
    We would be closer to 100° rather than 90° if the historic heat dome over Mexico didn’t get suppressed to our south across Florida. https://x.com/OSUWXGUY/status/1792912484979835203 Sweltering heat looks to continue across Mexico with the ECMWF ensemble mean showing mid level height anomalies as high as 4.7 STD DEV above the climate of just the past 20 years. Suggests a probability of ~1 in 769K
  10. bluewave
    Yeah, it’s probably related in some way to the many marine heatwaves across the planet right now. The Euro shifts back to cooler and wetter again from Memorial Day into the start of June. So no pattern change showing up just yet. May 27 to June 3 EPS forecast

    We got a south based blocking pattern in the summer of 2020 which was really wet so it held the 90° days down at Newark.
  12. bluewave
    The blocking pattern became more south based over the winter which featured the record warmth.
  13. bluewave
    This record blocking pattern near Hudson Bay has been in place since last May. It’s why we had a cooler summer last year. The only extended warmth with this pattern has been during the winter when it linked up with the Southeast ridge. So we need to see this pattern weaken in order to finally get some extended summer warmth. All the warm ups since March 20th have lasted a few days before more rains and onshore flow. Also notice how this pattern has resulted in the only cool spot in the Atlantic sea of record warmth has been to our east. https://x.com/WeatherProf/status/1793089595552456781

    The record heat stayed to our north today. RECORD EVENT REPORT NATIONAL WEATHER SERVICE BUFFALO NY 0442 PM EDT TUE MAY 21 2024 ...RECORD HIGH TEMPERATURE SET AT WATERTOWN NY...

    The big block this month near Hudson Bay continues to be a factor in the long range forecast. Low pressure begins crossing the Great Lakes as we head into Memorial Day. It could potentially slow down and cutoff next week near the Northeast.

    There are several issues that get mixed together. First, the global temperatures didn’t really begin to rise at a faster pace until emissions started accelerating around 1980. Large US urban centers like Philly haven’t seen that much expansion of the heat island in the downtown areas since then. This is why the NWS office in Mount Holly outside the Philly city heat island has seen the same amount of temperature rise since they moved out there in 1994 as the Philadelphia International airport. So all the rise over this period is due to the big global temperature increase. There are areas in China with new cities that have been built since 1980 so they get have a compound issue of global warming and heat island expansion. There are some US cities in the SW like Phoenix and Las Vegas that have seen major population booms and also have heat island expansion and global warming. Our part of the country has had major urbanization for over 100 years and city center populations have leveled off. Second, there are UHI studies that solely focus on satellite pavement temperatures and not the 2m temperatures the meteorological community looks at. So those very big 12° to 20° differences cited are the actual ground temp and not the cooler 2m temps. Sometimes the city and countryside can be more than 10° apart on nights with radiational cooling. But this effect has been consistent for nearly 100 years or more around our big cities so it’s nothing new. What’s new is the acceleration of global temperatures since 1980.

    Yeah, the warmest days this spring so far found a way to miss the weekends as expected. Probably not the pattern the beach vendors and concessions want to see. But this is what happened last summer also with cooler and damp weekends. Warmest days at Newark this spring 4-15…83°…Monday 4-29…86°…Monday 5-2….90°… Thursday 5-7…..83°… Tuesday 5-8…..89°…Wednesday

    Euro has some scattered showers on Saturday. So this would make it every spring weekend since the beginning of March with at least some measurable rain. Then we’ll have to see if that more organized area of low pressure develops for Memorial Day. Hopefully, the Euro is overdone on the rainfall amounts but at least some rain is possible. Still time for Monday to come into better focus on later runs. Newark and other stations have had at least a T of rain on every weekend this spring so far.

    The continuing Hudson Bay block did a good job this month keeping the record subtropical ridge and heat from Central America to Florida from expanding northward. So we are getting a back and forth between warm ups and cool downs but no record heat. Also one of the few times such a strong -PNA occurred with a mean trough near the East Coast.

    Anniversary of the warmest spring day on record around NYC Metro back in 1996. Deep WNW flow all the way out to Islip ahead of the sea breeze front. This was back in the days before these onshore flow patterns with high pressure east of New England began increasing. It’s ironic that our warmest spring day on record nearly reaching 100° occurred after the greatest winter on record for snow lovers. We also had one of our coolest summers after that. It was the last year with under 10 days reaching 90° at Newark. Data for May 20, 1996 through May 20, 1996 Click column heading to sort ascending, click again to sort descending.

    Yeah, temperatures should peak midweek before the cold front arrives. Places like Newark could reach 90° if the flow goes more SSW instead of the current SSE forecast with the slight bend in the streamlines. Best bet to reach 90° is probably in Central NJ away from the sea breeze. Plus areas from Albany to New Hampshire could reach 90° since sea breezes won’t be an issue there. Even your area on the North Shore could get into the 80s. Looks like a step down in temperatures as the stronger onshore flow returns by Memorial Day.
  24. bluewave
    While it’s too early to do a rainfall or clouds potential forecast for Memorial Day, looks like we could see more onshore flow with high pressure anchored east of New England.
