Around 7 or 8 o'clock morning, the high pressure system, I had predicted would move over the Eau Claire area did just that. You may have noticed calm winds this morning, this was due to the high pressure system's center being directly over Eau Claire. The nature of the high pressure system pushing wind outward in a clockwise orientation is the specific reason for this.
The surface map is currently depicting the center of the high pressure system has moved to the eastern edge of Wisconsin. I see a few dry lines on the surface map, but what else is there of note on this map? How about the low pressure system to our West? But is it a developing mid-latitude cyclone and how soon before that low pressure system is knocking on our doorstep?
Looking at the visible satellite image I can clearly tell this is not a mature mid-latitude cyclone. It has the potential but the stationary front in the system is the inhibitor. In order for a full mature mid-latitude cyclone to form the the cold air mass needs to over take the warm air mass in in the stationary front.
This is what a mature mid-latitude cyclone looks like (above). Regardless look for vertical growth in the cumulus clouds over the next twelve hours. It is possible that we could see some thunderstorms this evening and early tomorrow morning. I have a feeling we could in for a good storm tomorrow afternoon as well, more on that tomorrow though!
