I'm gonna study up a bit on what a 1050mb means, interesting stuff. Maybe it has something to do with this Vort I see you talk about Zack.
What it means is a 1050mb surface high pressure center, which is the winter the higher the pressure the colder the temperatures. The avg. surface pressure is around 1013mb and as the air gets colder it gets denser and the air tends to sink thus higher pressure. So in winter the higher the pressure is in a high pressure system usually the colder the weather.
The whole idea was to seed clouds in the outer bands with silver iodide which would cause the clouds to increase and cutoff the flow to the eyewall storms. This would cause the eye to increase and decrease the winds (much like eyewall replacement we see in strong hurricanes). They had some success, but after a day or so the winds would go back up. The biggest fear was that they did not know how this would effect the motion of the storm, possibly turning it in a different direction. There was also the expense and could only work with hurricanes with a certain type of structure.
