Hard to believe that it's been one week since an EF-2 tornado touched down in parts of Winnebago and Boone counties but here we are on the 29th of November and looking at almost a similar set up to last week. While the track of our next storm system will be almost the same as the one last week, there are however, a few things that are different. One is the fact that we are not going to be anywhere near as warm as we were last Monday. Temperatures on the 22nd were well into the upper 60s during the afternoon and thanks to the cloud cover this morning, we've had a hard time getting out of the upper 30s. Second, the warm front will stay well to the south whereas on Monday the warm front lifted northward into southern Wisconsin - and it was right along the warm front we were able to get enough spin in the atmsophere to create a tornado. Thirdly, the cold front will move through during the overnight which during this time of year would be really hard to get any severe weather going.
As we go through this afternoon the clouds will stick with us and dew points will rise some as moisture from the Gulf moves northward. We're already starting to see a few showers pop up across eastern Iowa as the trough/low pressure in the west moves east. Strong winds in the jetstream will continue to bring moisture northward which could lead to a steady rain later this afternoon and evening. With a little instability in the mid-levels a few thunderstorms can't be ruled out, some of which may produce small hail.
As the low moves into the Upper Great Lakes by Tuesday afternoon temperatures will likely fall into the low 30s with a few light snow showers possible. While no major accumulation is expected it may be enough to make roadways a little slick during the morning and afternoon commutes.
