1/Often with (PV) disruptions the stratosphere leads the troposphere. Currently the PV is split into two vortices separated by high pressure. In a week's time textbook Rex (high over low pressure-60W) & omega (Greek letter-60N) blocks are predicted in the troposphere

Oh no too bad it’s going to be extremely cold & snowy for the next few days... guess I’ll just have to stay inside & watch all of the Studio Ghibli movies. 🍃

Yes, the weather is mild today, but a is on the way, bringing the COLD winter weather with it. So the recommendations might not be so bad after all. And of course, this means more time for reading...

The December 28 2020 blog accurately predicted the upcoming weather across Europe based on the disruption. But now my thinking for North America is at odds with the weather models-so I pulled out my winter bingo card, what space did I land on? https://t.co/DHrQlUsLWp

GFS still predicting a (PV) split with this morning's run. Of course still an open question if we get a PV split but also does the N America daughter vortex end up in eastern N America? Could it allow a return of wintry weather to Eastern US sooner rather than later?

This week's blog is all (PV) all the time. Latest CFS predicts classic PV disruption for January. i give my thoughts for different scenarios and the implications for weather for the US, Europe, East Asia from weeks to months: https://t.co/NBg26lakvl

In today's blog I argue that the current Northern Hemisphere weather pattern is consistent with a split but when may we expect a pattern change? https://t.co/0rotabiRX0

The unprecedented 2020 northern hemisphere has come to an end. The split, allowing air into the Arctic, closely matching last week's forecast from the Monitoring Service.

Nerd post. March 2020 had a remarkable stratospheric pattern. Record low temps (white) on the N. America side of the Arctic. This is a reflection of the unusually strong, and late season ...........

Models consistently predict first weakening of the and warming of the polar stratosphere with cold air displaced to lower latitudes since November. What are the possible implications for our spring weather? https://t.co/cNZDZmod1S

The Oscillation remains positive and the (PV) strong but because the PV is predicted to be no longer circular but rather elongated along an axis from Siberia to Canada allowing cold air to spill out of the Arctic into Siberia and Canada in early March.
