...Synopsis and Discussion...
An amplified upper trough/low with an intense mid-level jet will
continue advancing east-northeastward over Ontario/Quebec and the
eastern CONUS today. A related strong surface cold front will also
move east-southeastward across the Southeast and Gulf through the
period. With negligible instability forecast over land ahead of the
front, thunderstorm probabilities still appear less than 10%.
