Saturday’s Weather Outlook; West/Plains/Great Lakes/Mississippi Valley/Northeast System

1:00AM

On Sunday, a system will continue to slowly push eastward through the Plains. Showers and storms will be possible over portions of the Northeast, Great Lakes, Mississippi Valley, Plains and the lower elevations of the West. There is a moderate risk for severe storms in portions of Kansas, Texas and Oklahoma, with a slight risk from Michigan down into Missouri. CAPE values will be around 2500 J/KG, LI’s of -7 and Effective Bulk Shear values of 30-50KT. This along with a system pushing through, will help storms become severe. Severe storms will develop along a frontal boundary from Michigan down through Missouri and into Oklahoma. These storms will push northeast through the Night, before weakening. The main threats from the severe storms will be hail, damaging winds and tornadoes. On the north side of the system, snow will be possible in the higher elevations of the West. Below is the severe weather and snowfall outlook for Saturday.
