Following the record Rockies/N Plains snowstorm came the record cold and this morning was another (record) cold one. This time over the Lower Midwest and interior Northeast with widespread 30s and low 40s. Even pockets of 20s! It’s all thanks to that cold, dry Canadian high which now spans a large swath of the country from the Rockies to East Coast. Some […]
Back at the close of July into the start of August, Ex-Hurricane Bertha brought an end to summer over the UK following the largely warm, dry June-July pattern.

Both Jamstec and CFSv2 show a warm fall for much of the US with warmest on both coasts with cool in the middle but head into winter and they go their separate ways. In fact one could argue that they go to the extreme. Jamstec fall temps CFSv2 fall temps Interestingly both models have almost identical […]

Jamstec has the warm/wet Sep-Nov period I’ve had since mid summer. Jamstec is going with warm/wet Europe but colder NW UK/Ireland winter (close call?) Note the very dry N Atlantic.

The NAO becomes more significant as we head from summer into autumn and obviously winter. Over the past 12 months, the NAO has been predominantly positive and I believe this is strongly connected to the weak solar maximum of sunspot cycle 24. The positive NAO has laid to a warm Europe last summer, winter and even summer this […]
