Weather Summary

High pressure dominated for a second day as a major storm began brewing over the Great Plains. Blizzard conditions, freezing rain, damaging winds and tornado-producing thunderstorms affected the central US from Colorado to Michigan and from Texas to Minnesota. Southern Ontario however, was quiet and clear. A few high clouds moved over extreme southwestern Ontario late in the afternoon ahead of the major storm, but that was it.

 

Flight Summary

There was no flight today.

 

Satellite Images

Images are taken every four hours beginning at 0045 UTC.

GOES-12 Visible (during daylight hours) and Near IR (night) albedo from CIRA.

 

GOES-12 IR (10.7 µm) brightness temperature from CIRA. The color scale begins at 0 °C with an increment of -10 °C between color changes.

 

GOES-12 experimental cloud phase from CIRA. Blue represents ice particles, red is liquid droplets above freezing and yellow represents supercooled liquid droplets. Gray areas are clear (no cloud) based on an IR cloud mask.
