Info on Friday/Saturday and the cold front:

Here are the rainfall maps for the Friday into Saturday night period from the Model Blend and Euro as a cold front will be coming through with rain possibly ahead of the front as well. Exact timing and details are still uncertain, and you can see the Euro is showing a good amount of rain. The Canadian model seems to be in that camp as well, and of course the GFS is different, showing less rain. You can see the warm temperatures ahead of the front and much cooler temperatures behind the front in the 3rd image from the Euro ensemble mean.
