Major storm system will develop across the Intermountain West and move into the Plains Wednesday-Friday. This storm will dump very heavy snow across the Rocky Mountains with Denver getting close to a foot in a half of snow by Thursday night. Here is the latest NAM 12Z model showing predicted snowfall accumulation by Thursday Evening.

Another big event of this storm system will be severe weather. This will start to become a threat by tomorrow evening(Wednesday evening) however it may take till overnight into Thursday morning before really getting going. A very strong jetstream will dive into the Southwest then eject out into the Plains by Thursday. This will create very strong sheared environment first across Oklahoma and Texas Wednesday night then expand northeast Thursday and Friday. Severe weather with a threat of tornadoes and Wind damage will develop and spread across Okahoma and Texas. Then Thursday and Friday east into Missouri, Arkansas, Louisans, Illinois, Indiana, Ohio, Kentucky, Tennessee, Alabama and Mississippi. As the low pressure forms over northeast New Mexico and races northeast into Northern Minnesota by Friday. Here is the latest SPC outlooks for Wednesday night and on Thursday.   -Justin-
