TOR Warning for portions of Oswego and Cayuga Counties…

Posted in Live Blogs on by Kristin Calhoun.

Based on the SRM radar data combined with a few MRMS products, Eric decided to issue a tor warning for the strengthening cell in Cayuga County at approx 1959 UTC.  Whether or not this storm has produced or will produce a tornado remains to be seen.  Nevertheless, here are some of the imagery which helped with the warning decision process…

The next image is the MRMS 0-2 km azimuthal shear product valid at approx 2000 UTC.  Notice the higher values in NE portions of Cayuga County coincident with the broad rotation noted on the KYTX radar.

Lastly, here is the MRMS low level 30 minute rotation tracks data valid at 1957 UTC.

Granted, there is still some product familiarity and pattern recognition needed with these newer types of data.
