I'm taking off for awhile.

a line of severe thunderstorms has broken out across Southern Ontario late this morning and have intensified early this afternoon while slowly tracking south and east. Some of these storms have cloud tops to 44,000 feet and hail associated with them.
The Niagara Peninsula is definetely under the gun this afternoon for some strong to severe thunderstorms...including my area
The line of storms is breaking out ahead and along a cold front slicing into 85F+ temperatures.
