Great Snow 1717 Posted February 26, 2019 Share Posted February 26, 2019 1 hour ago, weathafella said: The direction matters. As mentioned yesterday, half the gust speed on E winds would have created more havoc imby. I agree. I've seen more damage in the Merrimack Valley area on E/NE/SE winds than on W/NW/SW winds.

dendrite Posted February 26, 2019 Share Posted February 26, 2019 Frozen ground (in spots) and no leaves make a difference too. It’s hard to compare this to 10/17 when we had inches of rain, leaves on some trees, and easterly winds. Link to comment Share on other sites More sharing options...

This was said on-air last night by a certain local TV met. Link to comment Share on other sites More sharing options...

OceanStWx Posted February 26, 2019 Share Posted February 26, 2019 I grabbed the old April 1934 surface map to reverse engineer the mid level jet responsible for the 231 mph gust on MWN. The pressure gradient was 7 mb from PWM to Northfield, VT. The max gust was 103 m/s, so the "slower" wind speed would mean a 135 knot jet around the inversion. That's a pretty stout LLJ, but not impossible given the pressure gradient in place. Unfortunately we don't know what the vertical profile looked like that day. 1 Link to comment Share on other sites More sharing options...

Pinkham Notch original COOP form has rain-snow-sleet-gale in the comments for 4/12. 1st Lake has "gales". So it must've been pretty windy in the north country. Wish we had some kind of archaic tethered sounding data. Link to comment Share on other sites More sharing options...

Have you played with any of the data here? https://www.ncdc.noaa.gov/data-access/weather-balloon/integrated-global-radiosonde-archive Looks like BOS (72509) has data back to 1926.

I haven't used that at all. My raob program is not loving the format it gives you though, so I would have to dig into it a bit more. Link to comment Share on other sites More sharing options...
