1016 AM CST Thu Dec 12 2024
Valid 121630Z - 131200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Lightning is possible this evening and tonight along the eastern
shores of Lake Ontario in association with lake-effect snow bands.
...NY...
Cool/dry and stable conditions will prevail over the most of the
CONUS today, with no organized thunderstorm activity expected. One
exception will be in the vicinity of the eastern shores of Lake
Ontario (Jefferson/Lewis/Oswego counties). A long-fetch lake-effect
snow band is forecast to develop later this evening and tonight.
Forecast soundings suggest a sufficiently deep convective layer to
promote charge separation and a few lightning strikes - mainly after
02z.
