The traditional peak of the hurricane season has passed with very few storms, contrary to the predictions. Some of these predictions are based on the premise that warmer air can hold more water vapor. That is true, if the water can get there. Under current global warming conditions, where the air above the ocean surface warms faster than the ocean surface below, the intensity of the marine layer is greater and steadily increasing. Greater temperature differential means stronger low presssure systems are needed to lift moisture so winds aloft can distribute the moisture via the cyclone and atmospheric rivers. Temperature inversion along the ITCZ now makes for fewer thunderstorm clusters that feed water to the upper atmosphere. The Atlantic storm zone now abnormally quiet. With the exception of the Northeast, the North American continent is increasingly dry. In contrast, serious flooding still occurs around the world. Mostly thunderstorm "training" the result of stalled cold fronts. The cold air of the polar regions simply not as robust. Previously-decades ago-cold artic air plunged through the continents with breakneck speeds. Years ago a Canadian clipper could race down through the plains to freeze Florida oranges in just 48 hours. In today's world of weather, the movement of cold fronts is sluggish, frequenlly stalling out to create flooding in a confined area instead of distributing the rain widely along the moving front. The double whammy of global warming; drought and flooding.

Why call it the "Pacific Transition" pattern? I'm assuming it has to do with the changing seasons and the initiation of the Pacific storm train?

Weird that the CPC is calling this coming pattern +PNA... it messes me up, using their correlation composites. Takes longer to plot everything individually.

I average 32"/yr 30 minutes north of Baltimore. Since returning from CA in Jan 2017, I have averaged 11"/yr for those 8 years

Worth noting that the upcoming pattern resembles the pacific transition (PT) pattern. https://www.cpc.ncep.noaa.gov/data/teledoc/pt.shtml#:~:text=The PT pattern is associated,half of the United States.
