Coldest Air of the Season Thus Far Due Next Week

The cold air spoken about on a few previous blogs will engulf the region by Sunday and hold over the region into at least mid week. An Alberta Clipper will surge east-southeast across the northern Lakes late Saturday and bring a brief burst of milder air before the Arctic air BLASTS the Great Lakes late Saturday into Sunday. By Monday evening; the Arctic express will be fully revved-up from the Arctic south-southeast thru Canada down into the Great Lakes and East.



Look for the Clipper to surge the Arctic front thru the region Saturday evening after a rather, breezy mild Saturday with temperatures rising into the 40s across Southeast Lower Michigan. Normal highs for mid-late January are in the upper 20s to lower 30s across the region.


By Tuesday evening; a broad, expansive Arctic high pressure will be sprawled over the Midwest to the East Coast bringing the core of the Arctic cold to the States. Much of the area is snow-free; so while temperatures originating in the Polar region will be below normal, they will moderate a bit over the snow-less region. Coldest of days; Monday into Wednesday will see highs struggle to rise to between 10 and 20, while lows fall to around zero to around 10 above.




After the surge of Arctic air passes; we will turn our attention to a developing low pressure system late in the week which will bring the threat of snow as it moves toward the southern Great Lakes.
