GOES-17 (GOES-West) Mid-level Water Vapor (6.9 µm) images from the AOS site (above) showed the broad circulation around an anomalously-deep middle tropospheric cutoff low centered along the California coast on 08 April 2020. The system was producing record daily rainfall amounts, which in tandem with the clouds kept daily high temperatures at record low values at some locations across Southern California.

Overlapping 1-minute Mesoscale Domain Sectors provided GOES-17 “Red” Visible (0.64 µm) images at 30-second intervals (below) — which revealed the southeastward propagation of a compact circulation of clouds west of San Nicholas Island.
