This much ZR in a Nor'easter? That is quite uncommon. Not your typical overrunning/CAD situation with waves on a E-W front and cold wedges inland way to the SW. Also getting 3" of IP in any storm in New England, that's uncommon as well. You typically see that in the SEUS and Southern Plains. And to have blockbuster snow amounts just NW of this sig ZR/IP area at the same time? Even CoastalWx *has* to be impressed! Yet another over-performing storm in New England this winter, whether it be rainfall, snowfall, high winds, or coastal flooding. We've had it all. And looking at the pattern and GEFS for the next two weeks, all sort of "fun 'n game" potential lined up. This time of year, you are not going to get the long range explicitly showing a sig snowstorm these parts, but you can't deny the pattern is there for perhaps something. Why not? I think we let the furnace meteorological winter get to us too much. I say, get the big snows any way you can, even if it is a "bookend" winter, like 1981-82 and 1996-97 were. CoastalWx saying to himself now, "PLEASE let's get a March 31-April1, 1997 or April 6-7, 1982 repeat! Heck, he will even take May 9-10, 1977 or April 28-29, 1987, even though Weymouth-land missed out these two storms!

Oh, CoastalWx must be pining big time!

Thunder reported at Lempster NH around 8pm from a reliable observer I know. This matches a back end weenie +SN band on radar the moved thru in the last 90 min. This is the 3rd time he has had thundersnow this winter, the other two were the two strong cold front snow squalls days, the most recent on 3/20! Not so bad a winter after all, right CoastalWx?

Scott's all excited that BOS dropped from 42 to 37 F in 26 min!

Actually, May 1995 did not have a low tornado count. Quite the opposite with 391 tornadoes, the 7th highest monthly total on record. Be careful with taking statistics at face value on social media.

NOUS41 KWBC 161520 PNSWSH Service Change Notice 21-30 National Weather Service Headquarters Silver Spring MD 320 PM EDT Tue March 16, 2021 TO: Subscribers: -NOAA Weather Wire Service -Emergency Managers Weather Information Network -NOAAPort Other NWS Partners and Employees FROM: Captain James Crocker, NOAA Director, Surface and Upper Air Division Office of Observations SUBJECT: NWS Upper Air Station at Chatham, MA, to permanently close effective April 1, 2021 The NWS will cease all radiosonde observations (RAOB) and data transmissions from the Chatham, MA, upper air site, after the final sounding 12Z March 31, 2021. The WMO Site number is 74494 and the Site ID is KCHH. These two AWIPS products will cease effective April 1, 2021. These products are for the RAOB Mandatory (MAN) and Significant (SGL) levels observations. WMO HEADING AWIPS PIL USUS41 KBOX MANCHH UMUS41 KBOX SGLCHH Users should refer to upper air observations from the three nearest NWS upper air sites: Brookhaven, NY, (72501); Albany, NY, (72518); and Gray, ME, (74389). Following decommissioning of the Chatham upper air station, when weather conditions or circumstances warrant, these stations will make supplemental observations. Recent significant erosion of the coastal bluff where the Chatham upper air station is located is a safety concern for the personnel who launch radiosonde soundings. The balloon inflation building is at risk of loss from a landslide. For this reason, the NWS will decommission the site on March 31, 2021, and have the facility buildings demolished in April 2021. The NWS is actively seeking a new site for upper air observations in southeastern New England and will notify the user community when property acquisition is made. If you have questions or feedback, please contact: Hiram Escabi, Jr., NCE, CET Upper Air Program Manager NWS Program Management Branch Silver Spring, MD 301-427-9195 [email protected] NWS Service Change Notices are online at: https://www.weather.gov/notification/

I posted this several ago ago. Here is the update for 2017-2020, and also the complete file starting in the 19th century. I only listed killer or significant tornadoes prior to 1975, and all tornadoes 1975-2020. newenglandtor201720.txt newenglandtor.txt

Goni as strong as Haiyan? Going strictly by satellite here. I did a comparison of EIR and BD geostationary imagery (4 km resolution) at Goni's and Haiyan's peak intensity of 170 kt. Goni EIR 10/31/20 18z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2020wp22/4kmirimg/2020wp22_4kmirimg_202010311800.gif Haiyan EIR 11/7/13 1830z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2013wp31/4kmirimg/2013wp31_4kmirimg_201311071830.gif Goni BD 10/31/20 18z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2020wp22/4kmsrbdc/2020wp22_4kmsrbdc_202010311800.jpg Haiyan BD 11/7/13 1830z 170 kt https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2013wp31/4kmsrbdc/2013wp31_4kmsrbdc_201311071830.jpg Haiyan looks more symmetrical with a thicker/colder CDO ring and warmer/clearer eye. ----- Comparison of Polar EIR imagery (1 km resolution) Goni EIR 10/31/20 1225z https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2020wp22/1kmirimg/2020wp22_1kmirimg_202010311225.gif Haiyan EIR 11/7/13 1640z https://rammb-data.cira.colostate.edu/tc_realtime/products/storms/2013wp31/1kmirimg/2013wp31_1kmirimg_201311071640.gif Polar imagery is not at the same time but still Haiyan looks so much more impressive overall for its cold COD ring and a warmer/clearer eye overall. Geostationary imagery for Goni at 18z does not suggest its satellite presentation improved to this level from 1225z.

USAF did do recons in the WPAC (mostly out of Guam) until 1987. That's when I think full reliable geostationary coverage (GMS satellite) was available. It is virtually without a doubt there have been several STYs in the WPAC stronger than STY Tip. Haiyan (2013) and Zeb (1998) are likely candidates. A few more are discussed here: https://ams.confex.com/ams/26HURR/techprogram/paper_75465.htm https://ams.confex.com/ams/pdfpapers/75465.pdf Many TCs globally, weak and strong, are underestimated when no recon is present. Dvorak does best with systems 60-105 kt. This mean two things 1) a lot of TDs are actually weak TSs, and 2) the most intense TCs are often underestimated, sometimes by significant values. The smaller, more intense a TC is, the greater the error. Dvorak does not do well for small/tiny intense TCs. No way we would ever have got 215 mph for Patricia based on satellite, even if it was an average size TC. Usually TC centers will max 1-min winds at 185 mph for satellite-only estimates, such as EPAC Linda 1997 (likely strong than 185 mph). JTWC until Haiyan never went about 185 mph satellite-based only. Even Haiyan's 195 mph is only an estimate. In the hurricane re-analysis project for the Atlantic, adjustments to the most intense TCs are capped at 185 mph. Just no way to tell what really goes on in these mesoscale cores of intense TCs without recon, even with direct pressure readings as we now know how variable the winds can be for a given eye pressure. I will say with the FL Keys Labor Day hurricane in 1935, an 892 mb pressure and RMW smaller than Andrew's, and 30 mb lower than Andrew, that meant the winds were probably ~200 mph.
