🔴🔵⚠️❄❄🇺🇸🇨🇦More than 180M people hit by #Fern,the strongest #winterstorm in the last 5 years for #US & #Canada.More than 880000 power outages due to heavy #snowfalls and severe cold temperatures(-9°C in #NYC)⬇️24hrs by #GOES17 via

Given that today was the last day of the #GOES17 "Longitude Test", it's also likely the last time we'll be able to do a 4-GOES-R-series comparison. Here's a view of southern Lake Michigan from #GOES18/#GOES17/#GOES19/#GOES16, showing lake ice near the WI/IL/IN coast along with lake effect clouds.
On Dec 21 (local time in #Tonga), @NOAA #GOESWest/#GOES17 shows continued #eruptive activity at #Hunga Tonga-Hunga Ha'apai, with abundant #lightning in the #volcanic plume.
Data: #GOES GeoColor and Geostationary Lightning Mapper Group Energy Density products from @CIRA_CSU.
VOLCAT also recorded a very high #volcanic cloud vertical growth rate in #GOES17 & #Himawari8 data. At ~40 standard deviations above the mean meteorological cloud growth rate, this is among the highest rates reported by Pavolonis et al. (2018)....
Correction: #eruption on Dec 19 at 20:30 UTC (Dec 20 local time in #Tonga). #GOES17 images are from @CIRA_CSU.
#Sentinel5P #TROPOMI UV data measuring ~9 kilotons of SO₂ in the #volcanic cloud spreading north of #HungaTongaHungaHaapai at 2:00 UTC on Dec 20. @CopernicusEU
#Eruption of #HungaTongaHungaHaapai #volcano in #Tonga on Dec 20 at 20:30 UTC. #GOESWest (#GOES17) images show water/ice-rich #volcanic cloud and lightning detected by #GLM. Some SO₂ also being detected by UV/IR sensors. @Eruptn @MetService @MichaelFieldNZ @NOAASatellites
#Kilauea #eruption plume update. Latest #GOES17 imagery (@CIRA_CSU GeoColor) shows NE trade winds weakening & the #Halemaʻumaʻu plume drifting N of Kilauea. Vog (haze) visible in the #Hawaiian eddy downstream. NE trades forecast to return on Thurs. @USGSVolcanoes @NWSHonolulu
The dispersion of #volcanic SO₂ around the leeward (Kona) side of #BigIsland is beautifully shown in these #GOES17 GeoColor images from @CIRA_CSU. The plume is caught in the 'wake' of the island. #Kilauea summit plume also visible - until the orographic clouds roll in.
Lava, lava burning bright. Hotspot at #Kilauea #volcano holding steady through the longest night of the year. Flickering is mostly due to the passage of clouds overhead. #GOES17 data from @CIRA_CSU. #KilaueaEruption2020 #Solstice
You can also tune in to the #GOES16/#GOES17 hashtags, which are @NOAASatellites. Mostly you'll see things posted to @NOAASatellitePA though. They produce these unsatisfying summary maps as periodic work products. graphical.weather.gov/sectors/pacsouthwest.php
