Not every single model is on board with this solution, but the Canadian deterministic (not ensemble) model is showing a tropical system in the Gulf around the 20th. The GFS also has been waffling back and forth over a tropical system hitting the Carolina coast around the same time frame.
Canadian model precipitation output and wind fields/sea level pressure valid on the 24th:
And a crazy model run from the GFS, although this model has NOT been consistent from run-to-run, showing the 24th of May making a Carolina imapact:
This is ONLY something to watch and is NOT A FORECAST. Please do not take this literally since it is about A WEEK AWAY. Again, this is only SOMETHING TO WATCH FOR NOW AND SHOULD ***NOT CAUSE PANIC****. EVEN IF SOMETHING DOES FORM IT WILL BE VERY WEAK, SUCH AS A TROPICAL DISTURBANCE OR DEPRESSION AT THE MOST.
