This focus in recent days has been the severe weather and drought busting rains on the Southern/Central Plains as well as the summer warmth in the Midwest/East.

However, change is on the way as we progress through this week as an unusually cool Canadian high descends over the Great Lakes and eventually covers the Eastern US late week into next weekend.

This midday temperature map says a lot with 30s in the Dakotas (incoming cold) vs 80s up the East Coast (warm surge ahead of cool down).

The leading edge of this late season brand arctic air will bring 3-5 inches of snow to North Dakota tonight into tomorrow.

GFS surface shows strong surface heights and fairly low thicknesses over New England with this 1032 high.

850mb temps are also impressive by late May standards.

500mb height anomaly perspective.

Here’s what the model suggests for 2m lows Saturday morning. Yeah, I would imagine this is overdone.. I hope!

Will have more including a video tomorrow!
