Despite there being a strong -AO, it’s been a toasty October from the Plains to East Coast.

Despite this nice tropospheric warming event which forced the tanking of the AO…

This is the temperature anomaly across the US through the opening 18 days of Oct.

There’s an abrupt shift now underway for the East and despite this weekend’s winter-like slap in the face, the models continue to persist with a NEGATIVE in the Gulf of Alaska extending down towards California which supports continued storminess into the Pacific Northwest/British Columbia with western trough and continued ridging for the central and east.

This weekend will be a shock to the system.

This morning’s video looks at the details of the upper air setup but below GFS ensemble shows the warmth continuing through the rest of this month.
