Record autumn warmth will meet an early winter blast resulting in heavy mountain snow in the West and severe storms in the South, according to a report from CNN. 

Areas west of the Mississippi River will see “multitudinous weather hazards” thanks to an elongated area of low pressure that is going to swing East, according to the Weather Prediction Center. The same system will make contact with another one coming from the Pacific Northwest which will result in rain, snow and strong winds. 

Areas like Salt Like City have seen temperatures soaring to 70 degrees Farenheit but then dropped to below freezing by Wednesday evening, ushering in the first snowfall of the season. States like Utah, Arizona and Nevada can expect to see snow on Thursday before moving on to Colorado, New Mexico, Wyoming, Nebraska, and South Dakota.

The threats of tornados will make a comeback to the south as the season heads towards the end. Cold air from the West will hit the warm temperatures of the Midwest which can create severe storm systems starting late on Thursday and continuing into Friday morning. 

The Storm Prediction Center has issued a slight risk (level 2 of 5) of severe storms in parts of Oklahoma, Texas and Kansas and has added a marginal risk (level 1 of 5) to surrounding areas. “Damaging gusts, isolated large hail and a marginal tornado threat will be possible,” the SDC warned. 

Other parts of the South in parts of Oklahoma, Arkansas, Louisiana and Texas could see more severe storms from Friday morning onwards.  The SDC has issued an enhanced risk (level 3 of 5) of severe storms warning for parts of the these states. 

Heavy rain is expected to accompany the worsening weather with most areas likely to see at least 2 inches of rain, according to CNN.
