With a huge dip coming in the jetstream and plenty of cold air still hanging out in Canada. That will provide us with enough strength in the upper levels of the atmosphere to get things rolling on the surface.
The RPM holds on with the squall line right into eastern Ky. on Thursday evening. In some of the other data it begins falling a part. The bulk of the activity trys to develop south along the line and swallows most of the moisture. Those storms end up using more moisture so the transportation of the rest of it becomes a little more scarce. Now I am in no way saying we won't see severe weather. I am saying that the deep south should see a whole lot more.
By the time Thursday gets here I think many of you will begin to feel the moisture in the air. It will actually become humid outside. Not the overbearing July & August stuff. It will be much more noticable than it has been recently. I am thinking dewpoint readings will likely be in the low 60s in many areas on Wednesday and again on Thursday. Actually, higher on Thursday.
I'll have another update on Wednesday.
