A lobe of low pressure will pass through the region combined with a bump of warmer air leading to more clouds and a potential round of mixed rain and snow around our area mainly in the afternoon. This is just foreshadowing a much more significant storm system later in the week. Computer models are projecting a powerful low to form around the Southern Plains and lift an abundance of moisture into the upper Midwest and Great Lakes. The current track places the storm center in a postion favorable to produce significant accumulation in East Central Wisconsin. The precipitation would start as a rain/snow mix Wednesday night and rapidly change over to snow on Thursday, particularly far Northwest of Milwaukee with cold air wrapping into the back side of the storm. With warm air wrapping in ahead of the low there could be much less accumulation the farther East and South you go. Strong winds could lead to a period of blizzard-like conditions with blowing and drifting snow into Friday. Of course, all of this is predicated on the precise track of the system, so look for several tweaks to the forecast as it gets closer.
Have a great Tuesday!
