With the approach of an anomalously-deep 500 hPa low, an early-season winter storm produced very heavy snowfall and blizzard conditions across the Northern Plains — particularly in central/eastern North Dakota and southern Manitoba — during the 10 October – 12 October 2019 period. GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed the long duration of precipitation... Read More
Himawari-8 Advanced Himawari Imagery (AHI) from the ‘Target’ sector, above, show a strong albeit asymmetric storm south of Ise Bay and southwest of Tokyo Bay. Clean window infrared (10.41 µm) imagery, above, shows a compact eye that is cooling with time, suggesting weakening (and/or becoming more cloud-filled). Most of the... Read More
GOES-16 (GOES-East) Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) revealed the classic signature of a leeside cold frontal gravity wave (reference) moving southward across the High Plains on 10 October 2019. Peak wind gusts of 50-60 mph were reported at some sites in eastern Colorado and... Read More
SSEC/CIMSS is producing Advanced Clear Sky Processor for Ocean ACSPO Sea Surface Temperatures (SSTs) from Direct Broadcast data received in Madison. (Here is a blog post on ACSPO SSTs in Guam) The example above shows Great Lakes water temperatures around 0800 UTC on 10 October 2019. The example below shows SSTs computed from the... Read More
