Severe Severe weather threat (2/15 - 2/17)

...DISCUSSION...
An upper trough is forecast to develop eastward across parts of the
central/eastern CONUS from Day 4/Monday into Day 5/Tuesday.
Low-level moisture should return northward across parts of the Gulf
Coast states and the Carolinas ahead of a northeastward-developing
surface low. A severe risk may develop across parts of these
regions, mainly from late Monday into Tuesday. However, confidence
in sufficient destabilization to support surface-based storms is not
great enough to include 15% severe probabilities for now.

Medium-range guidance is in relatively good agreement that another
large-scale upper trough will move across the central/eastern states
around the Day 6/Wednesday to Day 7/Thursday time frame. Some severe
risk may once again materialize across parts of the central Gulf
Coast states and perhaps the Carolinas as low-level moisture returns
northward across these areas. Regardless, there is far too much
uncertainty in the prospect for substantial boundary-layer
destabilization to include any severe probabilities at this extended
time frame.
