Cold and rain north - warm and stormy south

Incoming low pressure late Wednesday night and Thursday will bring a surplus of moisture into northern Illinois and southern Wisconsin.  Initially the moisture will have a little dry air to overcome Wednesday afternoon, but by Wednesday evening light rain will likely be falling.

The same low that will bring us a rainy Thursday is also bringing severe weather to parts of Texas Tuesday evening.  Several reports of tornadoes and hail have occurred with severe weather moving into east Texas Tuesday night.

As the low moves northeast tonight and Wednesday, the severe threat will remain to the south.  The low will track through central Illinois (taking a similar track as the previous two storm systems), keeping us on the 'cooler' side.  Winds
will shift around to the southeast on Wednesday, and then to the east on Thursday.  A warm front associated with the low will fall short of northern Illinois, keeping highs in the low to mid 40's during the afternoon.  While south of the front temperatures will climb into the 60's and possibly near 70 degrees over southern Illinois.  Highs Friday remain in the middle to upper 40's, but we should return to the mid 50's by the start of the weekend.
