There’s a “big temperature contrast across the country as a battle of the seasons commences,” stated the Weather Prediction Center.
Cooler-than-average temperatures have infiltrated the West, whereas above-average temperatures are occupying the East.
Between the 2 competing air lots is the place the intense climate will battle.
Autumn extreme climate is similar to extreme outbreaks we see in early spring — as colder air clashes with the oncoming warming of spring, says CNN meteorologist Chad Myers.
“The shorter fall severe weather season occurs when the warm air of summer is pushed away by the incoming colder air of winter.”
Early-season snow storm
A storm system is already delivering welcome snow throughout the Rockies. Already a foot within the mountains of Montana.
“The snow is expected to be quite heavy to the west of the storm track over the northern High Plains tonight,” says the prediction heart. “Winter Storm Watches and Warnings are currently in effect where snowfall totals of 1 to 2 feet are possible.”
These winter climate alerts stretch from Utah to Montana.
The chance for tornadoes
“A supercell or two may pose a threat for significant (EF2+ damage) tornadoes, in addition to very large hail,” stated the SPC.
The best menace for tornadoes is in western Oklahoma and Kansas. There is an enhanced danger — degree 3 of 5 — for extreme storms.
Areas of slight danger — degree 2 of 5 — embrace extra of Oklahoma and Kansas and a small portion of Texas and Nebraska.
A marginal danger — degree 1 of 5 — of extreme storms stretches from southern Texas into South Dakota.
In addition, a harmful plume of moisture will transfer in throughout central Texas, together with Dallas.
Moisture from a landfalling hurricane named Pamela will stream into Texas and mix with this robust storm, stated CNN meteorologist Dave Hennen.
This surge of tropical moisture from the Pacific will result in widespread storms prone to produce a number of inches of rain from very heavy and intense downpours, based on the WPC.
Flood watches stretch from the Mexico, Texas border to the Texas, Oklahoma border.
