Tuesday May 14th … Dear Diary. The main purpose of this ongoing blog will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Wild Climate Disruption To Affect The United States Through The End Of May
Looking at meteorological models the last couple of days the old Climate Guy is really scratching his head. I can’t recall forecast 500 millibar patterns around the Northern Hemisphere this wild going through late May in my 35+ career of being a meteorologist. The lower 48 states will continue to take the brunt from what looks like obvious climate disruption. For today’s main topic let’s break the forecast evolution of the weather pattern down.
To start we will see more anomalous warmth near and north of the Arctic Circle, which will force cold pockets aloft southward towards lower latitudes. By Saturday we see this pattern, which is similar to what we have been experiencing the past month:
Snow in May? Yes, this is not that unusual or unprecedented, but one cold pocket has moved into the Northeast producing the white stuff:
The next lobe of energy coming out of the Southwest should produce more severe weather in the Plains along with exacerbating flooding around tributaries leading to the already woefully swollen Mississippi:
Speaking of the Mississippi:
This jet stream pattern looks very wild:
The West will be chilly under a highly unusual synoptic regime:
At the surface yet another strong low pressure center will move through the Plains this weekend producing more wet weather and severe storm havoc:
After the weekend we will see more strong Pacific systems move into the Southwest with probably one more ejecting into the Plains:
Rainfall totals could get seriously high again in the Mississippi River Basin next week:
One last system entering the Southwest next week is likely to consolidate into a large closed low and get stuck there for a few days. Consequently a very strong heat dome by May standards should build over the Southeast:
Just how strong remains to be seen, but anything over 594 decameters would be very impressive. I suspect that the southern Plains, Texas, and Southeast will experience record high temperatures next week if met models are correct.
Again, global warming is weakening the polar vortex, causing many more cold pockets to pinch off, producing this climate disruption. The weather pattern forecast for the last two weeks of May is a classic example:
From this article:
“It’s been proven that the jet stream has been shown to stall and recycle storms and wet weather for several weeks, if not months. Dr. Michael Mann argued this point with his depiction of the Quasi-Resonant Jet.”
We will see how all this plays out. Hopefully life and limb won’t be harmed, especially from severe storms and flooding, but unfortunately we will be lucky not to see fatalities from this coming weather pattern.
