Areas affected...northern Lower Michigan
Concerning...Severe Thunderstorm Watch 252...
Valid 201952Z - 202145Z
The severe weather threat for Severe Thunderstorm Watch 252
continues.
SUMMARY...A tornadic supercell may persist as it travels
east/northeast toward Lake Huron.
DISCUSSION...The storm co*plex that crossed Lake MI has indeed
evolved into a supercell, which has beco*e tornadic as it
encountered the warmer surface-based air mass. This storm is
currently producing a tornado near Gaylord, MI. The air mass
remains relatively warm for the duration of the expected storm track
over the next couple hours, and the 19Z APX sounding shows plenty of
low-level shear with 0-1 values around 280 m2/s2. This is higher
than objective analysis had earlier indicated. As such, the tornado
threat is expected to persist until the storm encounters the cooler
air near the lake.
