GOES-16 Air Mass RGB images, with and without contours of RAP40 model PV1.5 pressure [click to play animated GIF | MP4<\/strong><\/a>]<\/p><\/div>\n

GOES-16 (GOES-East)<\/em> Air Mass RGB<\/strong><\/a> images (above)<\/strong><\/em> showed the signature of a Potential Vorticity (PV) Anomaly — denoted by shades of red to pink within the comma head portion of the storm — which likely aided in enhancing precipitation rates within a midlatitde cyclone (surface analyses<\/strong><\/a>) as it moved across the region on 03 January 2022<\/strong><\/a>. RAP40 model contours of PV1.5 pressure indicated that the “dynamic tropopause” descended as low as the 900 hPa pressure level.<\/p>\n

GOES-16 “Red” Visible (0.64 \u00b5m<\/strong><\/a>) images with plots of hourly surface weather type (below)<\/strong><\/em> showed the distribution of precipitation from 1400-2120 UTC (9:00 am – 4:20 pm EDT). Overlapping 1-minute Mesoscale Domain Sectors provided imagery at 30-second intervals during this time period. Note the development of convective banding where heavier precipitation was being reported — this storm was responsible for producing flooding rainfall and significant snowfall<\/strong><\/a>.<\/p>\n

GOES-16 “Red” Visible (0.64 \u00b5m) and Day Snow-Fog RGB images [click to play animated GIF | MP4<\/strong><\/a>]<\/p><\/div>\n

On the following day, GOES-16 Visible and Day Snow-Fog RGB<\/strong><\/a> images (above)<\/strong><\/em> displayed the areal coverage of resulting swath of snow cover (shades of red in the RGB imagery), which stretched from northern Alabama and Georgia to southern New Jersey. A few patches of low stratiform clouds (shades of white in the RGB images) persisted in parts of the southern Appalachians during the day.<\/p>\n

A closer look at GOES-16 Visible and Day Snow-Fog RGB images (below)<\/strong><\/em> is centered on Virginia — and showed the portion of Interstate 95 in northern Virginia (between Fredricksburg KEZR and Washington KDCA) where hundreds of vehicles became stranded for as long as 24 hours. Snow depths<\/strong><\/a> were generally in the 8-12 inch range across that area.   <\/p>\n
