GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed the widespread precipitation (WPC Storm Summary) produced by a midlatitude cyclone that rapidly intensified off the Northeast US coast on 29 January 2022.

GOES-16 Water Vapor images with hourly plots of wind barbs and gusts (below) showed that the highest wind gusts occurred near the New England coast.

GOES-16 Air Mass RGB images (below) included contours of RAP40 model PV1.5 pressure — an indicator of the height of the “dynamic tropopause” — which showed that the dynamic tropopause had briefly descended to the 900 hPa pressure level at 20 UTC.
