Mild air will finally be moving in across the area today as a smaller 'bubble' of high pressure will set up in the Great Lakes Region
You can see on this surface map that there is a lot going on around us. Low pressure to our west and east, but finally some high pressure blocking any cloud cover and changing very little over the next 3 days. That's about all you can hope for right now as we have a very fast moving jet stream. Okay, so I know this is going to be a little mind expanding and I apologize for it in advance, but I wanted to show you the 200 mb chart. This is the place where the jet stream resides. You can see by the legend that we do have 100 knot winds pushing weather systems through very quickly. Right now that jet is driving the fastest moving air to the north. High pressure is also a factor in pushing this jet stream north. There's always been a debate in meteorology on whether the jet stream steers high and low pressure or low and high pressure steer the jet stream.

I may not always understand every detail of your posts but I greatly appreciate your willingness to explain more than what you can on TV about what is going on in the weather that is effecting our area.
Thanks, DW
