Quiet Before the Storm A weak cold front will go though Today...there is a slight chance for a few showers. Another weak front will go through on Friday. Both of these will add on colder air as we go into the weekend. This could be setting up a wintry mix of precipitation for us on Sunday Morning. It still looks like a big storm will be moving into the Eastern Great Lakes on Sunday. It will then transfer it's energy to a coastal storm in New England. There will be a swath of big snow from The Lakes into the NE...some areas could have blizzard conditions for a while. So, what does it mean for us? As the storm cuts West of here, a warm front will approach from the South Saturday Night. Overrunning precipitation will develop here by Early Sunday Morning. At that time, I believe we will be dammed in. The models are underestimating the strength of the cold air mass that we will have in place. If you are looking at the computer models right now, keep in mind they do not handle cold air damming very well from this far out. I believe we could see a few hours of pure snow here before it gradually changes over to a cold rain on Sunday. As everything passes on Monday, the arctic air will spill in behind the storm and temps should be falling all day. This NW flow will set up a big time Lake Effect Snow event Mon-Tue. As a matter of fact, I think some of those snow showers might make it into the Metro Area. Highs will be lucky to get out of the 20s on Tuesday....again, the models are underestimating the cold.
