Cool start to the week

Talk about a cool down. It looks like the main low has moved through our area and we are looking at a secondary low coming today and even early tomorrow.

Here is the secondary front in today you can see the shield of precipitation around this as it pulls down cooler air out of the north.
At 1:00 am it doesn't change much early tomorrow as a trough in the upper atmosphere still spinning around. Many times, especially during the winter and early spring we see the upper trough lagging behind the surface system.
A repeat performance tomorrow morning, although it looks like high pressure will begin to clear things out by late morning and early afternoon.
