?1557960602A heat dome over the Arctic caused by an atmospheric short circuit will create a catastrophic collision between cold air pushed out of the Arctic into the mountain west with Gulf of Mexico air over the midcontinent over the next ten days. While the Arctic sea ice melts at extraordinary rates under the heat dome a series of tornado outbreaks will ravage the plains and farm belt from Texas to Ohio. This map shows temperature departures from normal at at about 85% of sea level pressure - about 5000ft elevation.
The atmosphere had a convulsion at the end of April in the transition from winter to summer. The cold polar vortex in the stratosphere did not go gently into summer. Instead of fading slowly into a dome of warm air the whole atmosphere from the surface to the top of the stratosphere convulsed with wave energy driven upwards by an atmospheric dome over Scandinavia. Extraordinary atmospheric heating took place in the over the pole and cold air was pushed towards the temperate latitudes especially over the Pacific ocean. A dome of hot sinking air formed at very high levels over the Arctic pushing cold air and the jet stream south causing unseasonable storms to track across the Pacific ocean into California in mid May.

This animation shows 8 days of forecast atmospheric circulation at the level of 50% of surface pressure. Extremely intense waves on the jet stream will cause severe storms to track from Texas to the Canadian border in the midcontinent region while an extraordinary meltdown hits Arctic sea ice at the worst possible time early in the melt season when it will cause maximum Arctic amplification by increasing adsorption of heat by dark open water.
The European and American models agree on the main features there will be severe storms beginning this weekend lasting for a week or more but they have subtle differences in the timing and intensity of individual events. The most severe tornado outbreak is apparently going to begin on Monday or possibly Tuesday. However, severe weather outbreak forecasts arent reliable beyond 3 days or so, so expect modifications by local experts. Do not rely on anything I write here. This is written to give an early warning to people and because this is what climate change looks like. Consult your local NOAA weather forecasts to stay safe over the nest week. The American model shows an extremely unstable situation developing late Monday over Texas and Oklahoma.

An extremely unstable Gulf air mass will be sucked into an intense low pressure area developing over west Texas late Monday. It will be undercut by a very cold air mass pulled down over the mountain west by a disrupted jet stream. Note, the European model is a little slower, so this scenario could happen on Tuesday instead of Monday.

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS CENTERED OVER CENTRAL NEBRASKA AND WEST TEXAS.....SUMMARY... Severe storms are expected across parts of the Plains, mainly from Nebraska southward into west Texas. Very large hail and a few tornadoes are possible. Scattered severe hail is also possible across southern South Dakota, as well as across parts of Ohio and West Virginia.

I know, I should take it more seriously.
In one of the Laura Ingalls Wilder books, Little Town on the Prairie, I think, they had a summer in which there was one tornado after another. Very interesting reading.

Nothing to see here, no global warming, all good according to the Trump party.
The Republicans have sold out to the Fossil Fuel Industry in addition to Orange Mr. Bone Spurs.
