Sharp Regional SSTA Patterns Guide The U.S. Week 2-4 Outlook

Leading into August, sharp regional SSTA conditions support a semi-permanent trough near and southwestward the North Atlantic warm hole (NAWH) and south-southeast from the Gulf of Alaska Cool Pool. Extending northeastward across the Southwest U.S. toward Hudson Bay from the immense marine heatwave (MHW) off the Southwest Coast of North America is a semi-permanent high-pressure ridge.

What is TD 2/Bertha Potential?

At 8AM EDT, Tropical Depression 2 was located at 28,6N/85.6W or about 110 miles south of Panama City, FL moving northwest at 3 mph with top wind near 35 mph and surface pressure 1006 MB. Convection surrounding TD 2 is disorganized but increasing.

Global Wind Oscillation Phase_7 Encourages -NAO Pattern To (Eventually) Cool East U.S./East Europe

A strong positive phase global atmospheric angular momentum combined with the convection phase of the Madden Julian oscillation in the tropical East Pacific helps to force a semi-permanent global wind oscillation in phase_7. In this regime, there is a tendency to force negative North Atlantic oscillation. -NAO ahead forces an upper ridge near and southeast of Greenland with compensating upper troughs in northeast/east portions of North America and through Eastern Europe. Cooling results for Eastern Europe and eventually the Eastern U.S.
